AMD might not officially support it but there is little they can do to stop OEMs. Since OEMs intend to keep selling X470 boards support for PCIe "official" or not will become a selling feature. Brands that enable it will sell better than those that don't.
Actually there is little OEMs can do if AGESA flat out blocks it. On AMD platforms the OEMs really don't have that much influence on the core workings of the BIOS, unlike on Intel where they have all the control.
Also, I'm sure AMD has contracts with these companies and can dictate a lot of things.
They can always withhold shipments of X570 chipsets and Navi GPU,s to board vendors that would choose to circumvent their policy. And frankly I would be shocked if any board MFR offered it anyway as they would want to sell new motherboards anyway. That doesn't however mean that some very tech savvy people couldn't do it themselves, but I would not risk bricking my MB with a nodes bios.
Really there will be no pissing contest. The motherboard vendors aren't exactly quaking in their boots to back port PCIE 4.0 to older boards especially since the new boards cost more.
The old school perception that AMD has been fighting for 30 years is that AMD has inferior products and that it's not as reliable as Intel.
In order to fight that perception, they need to have products that are consistently faster, cheaper, and more reliable right out of the box. Having even a few models of older motherboards not work with PCIe 4.0 would muddy the waters and cast doubt once again. It would cause confusion in the marketplace and play right into Intel's hands.
Really, AMD is trying to support its customer base by keeping the socket the same. Sure, it would be nice to have PCIe 4, but the new Radeon RX 5700 will still work fine on PCIe 3. If you really want PCIe 4 you can always sell your old board and buy a new one, but I suspect most people will be ok just keeping their old one.
Unbloodylikely given that Zen 4 would be two generations and you don't really need PCIe 4, let alone 5. The use cases are so rare there's basically no reason to implement it.
Sure, those things will happen, but not in that timeframe.
Well, one use case is, you know, the chipset. It's limited to 4 lanes, so in order to reduce this bottleneck, more speed per lane is needed.
Now, with PCIe4, that bottleneck has widened compared to old chipsets and Intel, but you can still choke it by connecting lots of things to the chipset.

Probably more like 2 years and X770. 2021 is the next scheduled major chip update.
And that's assuming they can figure out a way to make a PCIe5 rated board without adding hundreds of dollars in repeater chips or super ultra quality PCB materials.
There is actually a big push on PCIe 5, much more than on PCIe4. There are a lot more design tools than for PCIe 4 at the same time after launch, and a lot of the MB issues they had to over come for PCIe4 will rollover to PCIe5. Panasobic has been ramping up MegTron production as well which will help TTM.
I'm not sure you've understood that (a) this is a company's marketing manager talking up the area it's got a vested interest in, and (b) what market they're referring to (hint; not consumer motherboards). As saratoga said, you won't be finding PCIe 5 in consumer boards for a while - it'll be very expensive with bugger-all use case. Even 4 is largely overkill, although it has the benefit of reducing the number of lanes needed to get the same bandwidth.
There’s no “big push”. 3 has been around too long, but there’s no way 5 will be pushed out that fast. At the very least, manufacturers have to amortize their investments in 4 first.
I think you mean around 24 months. The only thing coming out in your time period is Zen2+ and that's just going to improve clocks / IPC a bit. AMD didn't introduce anything with it's last refresh x470 chipset either.
"Having even a few models of older motherboards not work with PCIe 4.0" It's not only a few models. Every board with multiGPU support won't be able to run pcie4.0 on GPU's That's almost all x370, x470 boards and top of the line B350 boards. They could try to provide pcie4 only on NVME slots, but that mix might not be possible at all.
I dont get whay you are nagging about? you want pcie 4 buy an x570 motherboard. the entry ones are pretty good. You do realize that if no1 buys pcie4 there is no way to pay for the cost of R&D right ??
ppl don't buy new technology, than complain about lack of innovation ? its one thing to say i can't afford x570, i'll stick to b450. but than demand that some1 else pay for pcie4 to come to you is ridiculous. Intel won't even have pcie4 on comet lake and LGA1200, and you wont stop nagging about a 30 dollar premium
You don't understand how the BIOS/UEFI works for Intel/AMD. Intel and AMD have a core set of tweaks. OEMs provide a UI for those tweaks. If Intel/AMD remove the tweak, the OEM simply removes the UI for that tweak. In addition, if you dig into the BIOS using one of many tools, you can unlock hidden tweaks for nearly every board. For Zen 1 and Zen+, all those fancy "features" that manufacturers advertised were simply manipulating AMD CBS and PBS settings. From a BIOS/UEFI standpoint, there are actually no differences between manufacturers that are using the same AGESA version. Vendors simply customize their UEFI UIs to look 'flashier'.
Are we really buying AMDs reason? To me it seems more likely it's to push higher margin chipset sales (X570) but of course it's not PR friendly to state that. I'll also go so far as to say if it weren't AMD but competitors the reaction would also be more along those lines.
I would bet most people would be mainly interested in PCIe 4.0 support on either the x16 and/or one m.2 slot. Judging by some third party validation data at the moment this seems very doable on existing boards.
Instead you have to buy X570 at a higher price and deal with the higher power requirements and fan if you want any PCIe 4.0 at all. Good for extra chipset sales I suppose.
As for board signal integrity it's not as if OEMs can't design new revisions or even new models but just using the older (and cheaper) chipsets.
wouldnt it be possible for AMD to not allow support for pcie 4 in the bios, no matter what though ?? if it cant be enabled in the bios, there is little oems can do...
That is correct, AGESA (AMD Generic Encapsulated System Architecture) is more or less the "foundational code on which BIOS files ... are built" to quote Anandtech. I don't believe this code is not modifiable by OEMs.
It sounds like AMD is bundling support for the 3xxx series and the lock to PCIe 3.0 to the same AGESA release. Either the boards not going to POST or remain in fail safe mode, or it's going to recognize the 3xxx series CPU and be locked to PCIe 3.0
I dont get what there is so much hate for 30 dollar premium on x570 when you get pcie4. If it was up to intel we'd be on pcie3 and quad cores well into 2025.
you do realize that if no1 buys pcie4 there wont be pcie5 ??
AMD deserves a nobel prize for bringing pcie4 to mainstream and helping to reduce the cost of it and surrounding stuff like high quality PCB etc etc.
its one thing to complain at NAVI being so late, more power hungry than nvidia with a 7nm advantage and no RT/Tensor Cores, but on pcie 4 cmon. they just doubled your bandwidth and u cant stop nagging at their margins.
"intel we'd be on pcie3 and quad cores well into 2025.
you do realize that if no1 buys pcie4 there wont be pcie5 ??"
This is bias statement as it comes - Intel will have picie5 and just because pice4 could fail with AMD implementation. ( too early - maybe there is reason why Intel skip it ) does not mean PCIe5 will not exist.
You are leaving with AMD blinders on.
Yes Intel is struggling with 10nm and new machines but they have a lot of technology. Just remember Pentium 4 days and then intel came out with I series and dominated AMD so much.
Wondering how long it would take for you to come along with your shilling. It must really be killing you to see AMD in the news so much over the past few weeks.
And spare me your "AMD blinders on" spiel. You can't comment like that whatsoever, since your Intel blinders are so thick it's a wonder you don't bang into things everywhere you go.
What Intel did after Pentium 4 was essentially buy the market and force everyone to avoid AMD. And they lost a monopoly lawsuit over it. I don't think things will be so easy for them this time around. They may have to actually compete on merit. Yes, I know, a foreign concept.
Oh, stop it! You, and others here shill for AMD plenty. We’ll see just how long they have their minor advantage. This has happened before, in the early 2000’s, though you, and a lot of others are either too young to have experienced it, or choose to forget.
melgross, and you obviously havent been here long enough to see how he tries to turn ANY good news for amd, into bad, trying tp spread lies and BS about amd, while making intel look like the best thing since slice bread. when confronted with proof of this, he vanishes. he refuses to acknowledge any of the negative things intel has done over the years.
I’ve been here since the very beginning of the site. But no, I don’t bother to memorize everybody’s “name”.
And well, I’ve been around long enough to also know that AMD is often it’s own worst enemy. They’ve made so many major blunders over the decades that it’s amazing they’re still around.
But both companies have done some very good things as well as some very bad things.
I use both Intel and AMD, and recognize that both have had pros and cons over the years. AMD is currently in the lead, but no doubt Intel will come back at some point. I want that to happen, so they can cut each others' throats instead of doing it to us, the customer.
I was around in that timeframe, and long before that too. But this is about more than Intel vs. AMD. This is specifically about HStewart, and his extremely annoying posts. I've frequent lots of hardware boards, and even some that were before the Web/Internet was a thing. And I can say that in 25+ years of all this, I've __never__ seen someone that has shilled so hard for a company. If you had any experience here, you would have seen this too. He __really__ gets on my nerves with his illogical, incoherent comments, and I will take the opportunity whenever possible to take him down a notch.
Who is the shill now? Wow, the hypocrisy is off the charts. Let's conveniently leave out the behind the doors payments Intel made to OEMs to stifle any advantages AMD had back in the 2000s. Apparently Intel thought that "minor advantage" was enough to engage in unfair practices and rather pay a fine than forego the profits they were going to make.
And as always, it's an AMD ARTICLE. You may have a point if this were an Intel article and people were saying the same things but you are the one trying to promote Intel's superiority when the article is NOT about them. This article is obviously for fans of AMD products so you can't be more in the wrong with your statements.
melgross " AMD’s sales didn’t change. " maybe because the damage was already done ? and as Korguz said, if it was legal, when why did intel have to pay amd a few billion in damages/fines ?
shabby, that would be awesome if HStewart would do that.. i would LOVE to see his reasoning for once as to why he thinks PCIe 4 will fail with AMD. amd blinders, thats GOOD one, i wonder how big and thick HIS intel blinders are. i would also like to see where he gets this BS about intel skipping pcie4 and going straight to pcie 5. sorry HStewart, but azfacea is correct, if intel had their wait, we would still be on pcie 3 and quad cores. " Yes Intel is struggling with 10nm and new machines but they have a lot of technology. Just remember Pentium 4 days and then intel came out with I series and dominated AMD so much. " this is golden !!! they also have A LOT of money, clout in the tech industry, and with that comes bribes, kick backs and threats. JUST like they did back in the pentium 4 days, and look what that COST your beloved intel HStewart. gosh this guy really IS a shill, he HAS to find a way to make intel look better...
“The use of PCIe Gen 5.0 is also a big element to Agilex, as it allows customers to connect directly with future PCIe 5.0 host devices” https://www.anandtech.com/show/14149/intel-agilex-... I do not endorse HStewards opinions, but it seems to me like Intel might skip pcie gen4.
Agreed! Intel is probably crapping their pants because AMD has been catching up so fast, especially in heavily threaded programs. Gamers only take you so far.
Richlet, you are also forgetting that amd now has IPC parity ( or very close to it ), uses less power, is as fast or faster, while still charging less, case in point, ryzen 7 3800x, $550 VS i9 9900k, $700
And yet, Intel still gets the advantage because now when reading articles that 'minor' power savings is hardly worth mentioning. Yeesh, AMD can't catch a break. When AMD uses more power, you see comments in the spirit but not exact wording of "it would be competitive if not for the power consumption" or "good numbers but the power you have to use to reach that is ridiculous". When Intel is behind in power consumption you now get "wow, I'll save $7 a year now if go with the AMD" or "it runs a little warm but look at that single thread performance and the fps in my games, too bad for AMD because I want 220fps as opposed to 208fps when playing Fortnite".
That is why I don't buy anyone accusing AMD fans of being shills. I don't frequent Intel articles so can't say what kind of AMD presence exists there but I can definitely say I constantly see Intel shills on these AMD articles. If their product is so great they wouldn't need to be here trying to convince others and they would be busy enjoying their overpriced performance.
Nobel prize? I assume you just joking about that. This is all about competition. While for a while, and was moving in on Intel, that’s stopped more recently. AMD is just racing to get ahead of Intel here. If they can, they believe they’ll have a marketing advantage. If Intel gets ahead, AMD’s sales will suffer somewhat.
But make no mistake about it, very few in business, government, and particularly those who are consumers, need 4 anytime soon. Most people won’t see any advantage from this for years to come.
about competition ? what about innovation ? what about moving the cpu industry forward ? intel pre zen, didnt even do that, but if you want to call <10% performance gains year over year, sticking the main stream with quad core cpus, and stagnating the cpu industry a good thing, all while raising prices to ridiculous levels, then thats your choice.
Please, don’t be that naive. It’s all about competition, sales and profits. I’ve run two companies over the years. It doesn’t work the way you think.
When the founders if a company come up with what they think is a great, and useful, idea. They know that they have to make it profitable. In the beginning, that idea is enough to sustain growth. But when competitors appear, that changes. At that point, it becomes a matter of survival, and in order to do that, their ideals need to be modified. So both AMD and Intel obviously need to continue producing better parts, they also have to persuade people to upgrade.
The industry has changed from one of major growth, to one of mostly replacement, and that’s a totally different market. Intel has an advantage, because their R&D is more than AMD’s sales. Intel has been trying to do more than AMD could ever possibly afford to do. Intel has gotten bogged down at 10nm, not because they’re incompetent, but because they have been trying to do much more than their competitors at that node, rather than taking the easy way out. That’s resulted in wasted time in new designs.
But if anyone doubts that they will catch up, then they’re wasting their own time arguing that. Hopefully we all remember Netburst, and how Intel got hung up on that, but then recovered, and how AMD blew their chance to maintain parity with Bulldozer, with which they made their own major blunders.
The point is that we’re looking at this situation through a slice of time. At any point, things can change drastically. I don’t see that understanding here, where there are cliques for one side or the other,
The big thing for X570 is the PCIe 4.0 link to the CPU and the PCIe 4.0 downstream links. Everything before that is 3.0 to CPU (slow-ish) and 2.0 downstream, which is the real bummer. I honestly don't care if I have a 4.0 GPU slot and even a 4.0 NVMe slot is not that important. Would would be nice is to have three x4 3.0 slots for NVMes and the possibility of another x4 slot for a 10G NIC. Most boards of the 3xx and 4xx variety only offer two PCIe NVMe slots (one 3.0, one 2.0 or x2 3.0) and then the x4 2.0 slot might be shared with that NVMe slot. There isn't a lot of connectivity. And if you are heavily into USB, X570 offers a lot more flexibility there as well. 4.0 from the CPU is the least interesting thing about that platform (kinda) in my opinion.
Have you ever done RF board design? Have you ever seen the price of rodgers? If I were making a motherboard specification I would not let it up to companies that barely do any work besides source components, assemble them, and paste lights on them to responsibly design and validate a PCIe 4.0 channel.
are we really deserving if free pcie upgrades? how is this a normal expectation? when did this happen before? nothing was taken away since the idea only appeared a few months ago yet you twist this into a conspiracy out of nowhere, on a cheap platform, with the competition not having pcie4 either, absolutely selfish demands & accusations
how about dont buy x570, blame pcisig for being 3 years late, wait a few nanoseconds for the data transmission
limitedaccess seems logical... wouldnt you be a little pissed.. if you bought a x470 mobo, was told you could get pcie 4 with it when you upgraded to a ryzen 3 series, only to find out it wont run at that speed cause of poor quality, or some other reason ? " As for board signal integrity it's not as if OEMs can't design new revisions or even new models but just using the older (and cheaper) chipsets. " maybe they could.. but why bother? designing, testing, validating.. only to save a few bucks over an X570 board, probably not worth it for the mobo makers...
True, I am using 3700x with Msi b450 Tomahawk, atleast I dont have to spend 170$ or more for motherboard and currently it satisfies all the requirements in terms of connectivity for me. As of now I see no need for pci-e 4 connectivity(maybe when 10G nics start appearing with pci-e interface).
I think it is more likely to give mb company a fair playground, since not all x470/450 are build equally, so some company opt to use better pcb, wiring(like asus) will have advantage give almost all their board pcie4 while others cannot. it kinda like review imbargo, make it somewhat a fair play.
Not surprising. The X570 Chipset is actually just the I/O Die on GloFos 14nm process. Not only does AMD earn money with every X570 mainboard sold, they probably use the I/O Die to fulfill the wafer contract they signed with GloFo. AMD has all the interest to differentiate between X470 and X570.
People who are complaining about not getting retroactive PCIe Gen 4 support clearly do not understand what that entails. The standard requires power. LOTS more power. AMD is covering its ass by not releasing backwards compatibility because PCIe Gen 4 has the potential to -fry- your motherboard. Short of possibly very high-end boards, the circuit pathways cannot stably handle the extra power requirements, nor do they have adequate heat dissipation required to keep things cool. Have a good look at the preliminary boards. Most, if not all of them have on-board fan coolers for that reason. To be frank, I can't blame AMD for not wanting to be responsible for the IMMEDIATE backlash of people trying to RMA partner boards because their BIOS update fried them. You don't shoot yourself in the foot intentionally, and that is what it is tantamount to by AMD.
For the record, I have an X399 board running TR2. Now, it's -possible- that my board could handle it, but I wouldn't want risking borking my $400 mobo over a feature that will not really improve anything for me. I have no PCIe Gen 4 devices. Video cards(I run a 2080) do not even fully saturate PCIe Gen 3 yet, so there would be negligible improvement to performance there, if any. Backwards compatibility would be nice, but not at the risk of fragging my very expensive-to-replace HEDT system.
You are mixing all sorts of things here, mate. The signal does not require a lot of power, just very clear paths without crosstalk/interference and what-not. The power comes from the actual switching frequencies in the silicon. But enabling PCIe 4.0 on older chipsets would not make those chipsets suddenly be 4.0 compliant. They would still be 3.0 from CPU to chipset and 2.0 from chipset everywhere else. The only 4.0 lanes would be those 20 from the CPU to the x16 slot (GPU) and x4 slot (NVMe). That added power would be dissipated by the CPU heatsink or the thing would throttle (unlikely as the Wraith coolers have not increased in this new generation).
I mean I was able to mod a bios for my z170 to run an i5 8600 due to the work of modders on a forum so i can't see why the likes of asrock, gigabyte, Asus, msi and the likes who actively make bios and firmware couldn't hack it in regardless of the agesa code, I mean gigabyte boards started supporting it months ago before amds announcement but Asus literally just announced it on certain slots on certain boards even after amd said it wasn't supporting it so I imagine they might keep it going. This is also the kind of thing that Asrock would love doing like they done with the external bclk generated for 6th gen intel
hmmm .mobo mAkers can mod a bios and possibly enable pcie gen 4 ? or they can sell a new motherboard.. so old boards come back after being broken thru bad flash or gen4 doesnt work ? They will sell the new gtd Mobo every day of the day, and twice on Sunday
It depends on how far AMD will go. It is OK to drop official support while letting MB makers to put their own effect. It will be ugly if AMD try to prevent or even forces all MB makers to drop their support.
Why can't people accept that some % of existing boards will run into problems if pcie4 is enabled. Because there are literally 0 products that benefit from pcie4, and problems may result, they will not enable it.
really too bad I have to get a 570 to get PCIe4. There's no way I am getting a mobo that requires active cooling on the chipset. I am done with fans smaller than 120mm. Loud, die easily, just forget that noise. Hopefully they get a process shrink on the chipset soonish
Signal intergrity is only formal, explanation, in reality AMD is hungry for cash. PCIE requires error correction, so data always is trasmited correctly, but with lower speed. Seems than older mobos handle transmision to well, with very rare errors that do not seriously slow donw transmission, so it must be disabled.
TristanSDX, " in reality AMD is hungry for cash " care to share your proof of this ? a link perhaps ? as Richlet said, intel and nivida aren't ? maybe you should keep buying their over priced products and give them your money instead ?
So AMD is offering two AGESA codes, one in beta form with the PCI-E Gen4 enabled for older boards, and another stable without? I can see some reasoning behind this, but definitely not the most consumer friendly of moves.
nor really, the one that enables PCIe4 on older boards, was beta/pre release when amd thought they could add support for older boards, the new codes, disables it on older boards.
i doubt that support will last, once asus gets new bios's from amd with this AGESA code removed, and bios's get updated with that code. but, can asus guarantee pcie 4 support on these boards as they claim, on ALL boards ? what happens if 2 people have the same board, and one is able to have pcie 4, and the other doesnt, then what ?
How many people have complained about low end first and second generation AM4 motherboards that won't get third generation Ryzen support because the motherboard makers decided not to bother? How about the motherboards that don't have the VRMs to support Ryzen 9(3900X and 3950X), and people claiming that AMD isn't honoring the support of socket AM4 through 2020? It has been a given that some new features WILL require a X570 or B550 motherboard. There is also the problem of motherboard quality, and AMD is making sure that a feature that AMD claims to support will NOT work on 75% of the motherboards out there.

Zen2+ officially doesn't exist. The next step on the roadmap is Zen3.Granted, Zen+ didn't originally exist on the roadmap either.
Anyway, I expect neither of these will feature PCI-E 5 or DDR5.

"Having even a few models of older motherboards not work with PCIe 4.0"It's not only a few models.
Every board with multiGPU support won't be able to run pcie4.0 on GPU's
That's almost all x370, x470 boards and top of the line B350 boards.
They could try to provide pcie4 only on NVME slots, but that mix might not be possible at all.
azfacea - Saturday, July 13, 2019 - link
I dont get whay you are nagging about? you want pcie 4 buy an x570 motherboard. the entry ones are pretty good. You do realize that if no1 buys pcie4 there is no way to pay for the cost of R&D right ??ppl don't buy new technology, than complain about lack of innovation ?
its one thing to say i can't afford x570, i'll stick to b450. but than demand that some1 else pay for pcie4 to come to you is ridiculous.
Intel won't even have pcie4 on comet lake and LGA1200, and you wont stop nagging about a 30 dollar premium

You don't understand how the BIOS/UEFI works for Intel/AMD. Intel and AMD have a core set of tweaks. OEMs provide a UI for those tweaks. If Intel/AMD remove the tweak, the OEM simply removes the UI for that tweak. In addition, if you dig into the BIOS using one of many tools, you can unlock hidden tweaks for nearly every board. For Zen 1 and Zen+, all those fancy "features" that manufacturers advertised were simply manipulating AMD CBS and PBS settings. From a BIOS/UEFI standpoint, there are actually no differences between manufacturers that are using the same AGESA version. Vendors simply customize their UEFI UIs to look 'flashier'.limitedaccess - Friday, July 12, 2019 - link
Are we really buying AMDs reason? To me it seems more likely it's to push higher margin chipset sales (X570) but of course it's not PR friendly to state that. I'll also go so far as to say if it weren't AMD but competitors the reaction would also be more along those lines.I would bet most people would be mainly interested in PCIe 4.0 support on either the x16 and/or one m.2 slot. Judging by some third party validation data at the moment this seems very doable on existing boards.
Instead you have to buy X570 at a higher price and deal with the higher power requirements and fan if you want any PCIe 4.0 at all. Good for extra chipset sales I suppose.
As for board signal integrity it's not as if OEMs can't design new revisions or even new models but just using the older (and cheaper) chipsets.

wouldnt it be possible for AMD to not allow support for pcie 4 in the bios, no matter what though ?? if it cant be enabled in the bios, there is little oems can do...weilin - Saturday, July 13, 2019 - link
That is correct, AGESA (AMD Generic Encapsulated System Architecture) is more or less the "foundational code on which BIOS files ... are built" to quote Anandtech. I don't believe this code is not modifiable by OEMs.It sounds like AMD is bundling support for the 3xxx series and the lock to PCIe 3.0 to the same AGESA release. Either the boards not going to POST or remain in fail safe mode, or it's going to recognize the 3xxx series CPU and be locked to PCIe 3.0

I dont get what there is so much hate for 30 dollar premium on x570 when you get pcie4. If it was up to intel we'd be on pcie3 and quad cores well into 2025.you do realize that if no1 buys pcie4 there wont be pcie5 ??
AMD deserves a nobel prize for bringing pcie4 to mainstream and helping to reduce the cost of it and surrounding stuff like high quality PCB etc etc.
its one thing to complain at NAVI being so late, more power hungry than nvidia with a 7nm advantage and no RT/Tensor Cores, but on pcie 4 cmon. they just doubled your bandwidth and u cant stop nagging at their margins.

"intel we'd be on pcie3 and quad cores well into 2025.you do realize that if no1 buys pcie4 there wont be pcie5 ??"
This is bias statement as it comes - Intel will have picie5 and just because pice4 could fail with AMD implementation. ( too early - maybe there is reason why Intel skip it ) does not mean PCIe5 will not exist.
You are leaving with AMD blinders on.
Yes Intel is struggling with 10nm and new machines but they have a lot of technology. Just remember Pentium 4 days and then intel came out with I series and dominated AMD so much.

Wondering how long it would take for you to come along with your shilling. It must really be killing you to see AMD in the news so much over the past few weeks.And spare me your "AMD blinders on" spiel. You can't comment like that whatsoever, since your Intel blinders are so thick it's a wonder you don't bang into things everywhere you go.
What Intel did after Pentium 4 was essentially buy the market and force everyone to avoid AMD. And they lost a monopoly lawsuit over it. I don't think things will be so easy for them this time around. They may have to actually compete on merit. Yes, I know, a foreign concept.

Oh, stop it! You, and others here shill for AMD plenty. We’ll see just how long they have their minor advantage. This has happened before, in the early 2000’s, though you, and a lot of others are either too young to have experienced it, or choose to forget.Korguz - Sunday, July 14, 2019 - link

I’ve been here since the very beginning of the site. But no, I don’t bother to memorize everybody’s “name”.And well, I’ve been around long enough to also know that AMD is often it’s own worst enemy. They’ve made so many major blunders over the decades that it’s amazing they’re still around.
But both companies have done some very good things as well as some very bad things.

I use both Intel and AMD, and recognize that both have had pros and cons over the years. AMD is currently in the lead, but no doubt Intel will come back at some point. I want that to happen, so they can cut each others' throats instead of doing it to us, the customer.I was around in that timeframe, and long before that too. But this is about more than Intel vs. AMD. This is specifically about HStewart, and his extremely annoying posts. I've frequent lots of hardware boards, and even some that were before the Web/Internet was a thing. And I can say that in 25+ years of all this, I've __never__ seen someone that has shilled so hard for a company. If you had any experience here, you would have seen this too. He __really__ gets on my nerves with his illogical, incoherent comments, and I will take the opportunity whenever possible to take him down a notch.

"minor advantage" "AMD blinders"Who is the shill now? Wow, the hypocrisy is off the charts. Let's conveniently leave out the behind the doors payments Intel made to OEMs to stifle any advantages AMD had back in the 2000s. Apparently Intel thought that "minor advantage" was enough to engage in unfair practices and rather pay a fine than forego the profits they were going to make.
And as always, it's an AMD ARTICLE. You may have a point if this were an Intel article and people were saying the same things but you are the one trying to promote Intel's superiority when the article is NOT about them. This article is obviously for fans of AMD products so you can't be more in the wrong with your statements.

Richlet, you are also forgetting that amd now has IPC parity ( or very close to it ), uses less power, is as fast or faster, while still charging less, case in point, ryzen 7 3800x, $550 VS i9 9900k, $700Tewt - Monday, July 15, 2019 - link
And yet, Intel still gets the advantage because now when reading articles that 'minor' power savings is hardly worth mentioning. Yeesh, AMD can't catch a break. When AMD uses more power, you see comments in the spirit but not exact wording of "it would be competitive if not for the power consumption" or "good numbers but the power you have to use to reach that is ridiculous". When Intel is behind in power consumption you now get "wow, I'll save $7 a year now if go with the AMD" or "it runs a little warm but look at that single thread performance and the fps in my games, too bad for AMD because I want 220fps as opposed to 208fps when playing Fortnite".That is why I don't buy anyone accusing AMD fans of being shills. I don't frequent Intel articles so can't say what kind of AMD presence exists there but I can definitely say I constantly see Intel shills on these AMD articles. If their product is so great they wouldn't need to be here trying to convince others and they would be busy enjoying their overpriced performance.

minor power saving ?? i dont consider a 50 to 100 watt difference minor.melgross - Sunday, July 14, 2019 - link
Nobel prize? I assume you just joking about that. This is all about competition. While for a while, and was moving in on Intel, that’s stopped more recently. AMD is just racing to get ahead of Intel here. If they can, they believe they’ll have a marketing advantage. If Intel gets ahead, AMD’s sales will suffer somewhat.But make no mistake about it, very few in business, government, and particularly those who are consumers, need 4 anytime soon. Most people won’t see any advantage from this for years to come.
Korguz - Sunday, July 14, 2019 - link
about competition ? what about innovation ? what about moving the cpu industry forward ? intel pre zen, didnt even do that, but if you want to call <10% performance gains year over year, sticking the main stream with quad core cpus, and stagnating the cpu industry a good thing, all while raising prices to ridiculous levels, then thats your choice.melgross - Monday, July 15, 2019 - link
Please, don’t be that naive. It’s all about competition, sales and profits. I’ve run two companies over the years. It doesn’t work the way you think.When the founders if a company come up with what they think is a great, and useful, idea. They know that they have to make it profitable. In the beginning, that idea is enough to sustain growth. But when competitors appear, that changes. At that point, it becomes a matter of survival, and in order to do that, their ideals need to be modified. So both AMD and Intel obviously need to continue producing better parts, they also have to persuade people to upgrade.
The industry has changed from one of major growth, to one of mostly replacement, and that’s a totally different market. Intel has an advantage, because their R&D is more than AMD’s sales. Intel has been trying to do more than AMD could ever possibly afford to do. Intel has gotten bogged down at 10nm, not because they’re incompetent, but because they have been trying to do much more than their competitors at that node, rather than taking the easy way out. That’s resulted in wasted time in new designs.
But if anyone doubts that they will catch up, then they’re wasting their own time arguing that. Hopefully we all remember Netburst, and how Intel got hung up on that, but then recovered, and how AMD blew their chance to maintain parity with Bulldozer, with which they made their own major blunders.
The point is that we’re looking at this situation through a slice of time. At any point, things can change drastically. I don’t see that understanding here, where there are cliques for one side or the other,

The big thing for X570 is the PCIe 4.0 link to the CPU and the PCIe 4.0 downstream links. Everything before that is 3.0 to CPU (slow-ish) and 2.0 downstream, which is the real bummer. I honestly don't care if I have a 4.0 GPU slot and even a 4.0 NVMe slot is not that important. Would would be nice is to have three x4 3.0 slots for NVMes and the possibility of another x4 slot for a 10G NIC. Most boards of the 3xx and 4xx variety only offer two PCIe NVMe slots (one 3.0, one 2.0 or x2 3.0) and then the x4 2.0 slot might be shared with that NVMe slot. There isn't a lot of connectivity. And if you are heavily into USB, X570 offers a lot more flexibility there as well. 4.0 from the CPU is the least interesting thing about that platform (kinda) in my opinion.willis936 - Saturday, July 13, 2019 - link
Have you ever done RF board design? Have you ever seen the price of rodgers?

I think it is more likely to give mb company a fair playground, since not all x470/450 are build equally, so some company opt to use better pcb, wiring(like asus) will have advantage give almost all their board pcie4 while others cannot. it kinda like review imbargo, make it somewhat a fair play.Galatian - Saturday, July 13, 2019 - link
Not surprising. The X570 Chipset is actually just the I/O Die on GloFos 14nm process. Not only does AMD earn money with every X570 mainboard sold, they probably use the I/O Die to fulfill the wafer contract they signed with GloFo. AMD has all the interest to differentiate between X470 and X570.Averant - Saturday, July 13, 2019 - link
People who are complaining about not getting retroactive PCIe Gen 4 support clearly do not understand what that entails. The standard requires power. LOTS more power. AMD is covering its ass by not releasing backwards compatibility because PCIe Gen 4 has the potential to -fry- your motherboard. Short of possibly very high-end boards, the circuit pathways cannot stably handle the extra power requirements, nor do they have adequate heat dissipation required to keep things cool. Have a good look at the preliminary boards. Most, if not all of them have on-board fan coolers for that reason. To be frank, I can't blame AMD for not wanting to be responsible for the IMMEDIATE backlash of people trying to RMA partner boards because their BIOS update fried them. You don't shoot yourself in the foot intentionally, and that is what it is tantamount to by AMD.For the record, I have an X399 board running TR2. Now, it's -possible- that my board could handle it, but I wouldn't want risking borking my $400 mobo over a feature that will not really improve anything for me. I have no PCIe Gen 4 devices. Video cards(I run a 2080) do not even fully saturate PCIe Gen 3 yet, so there would be negligible improvement to performance there, if any. Backwards compatibility would be nice, but not at the risk of fragging my very expensive-to-replace HEDT system.
Death666Angel - Saturday, July 13, 2019 - link
You are mixing all sorts of things here, mate. The signal does not require a lot of power, just very clear paths without crosstalk/interference and what-not. The power comes from the actual switching frequencies in the silicon. But enabling PCIe 4.0 on older chipsets would not make those chipsets suddenly be 4.0 compliant. They would still be 3.0 from CPU to chipset and 2.0 from chipset everywhere else. The only 4.0 lanes would be those 20 from the CPU to the x16 slot (GPU) and x4 slot (NVMe). That added power would be dissipated by the CPU heatsink or the thing would throttle (unlikely as the Wraith coolers have not increased in this new generation).Agaonm - Saturday, July 13, 2019 - link
I mean I was able to mod a bios for my z170 to run an i5 8600 due to the work of modders on a forum so i can't see why the likes of asrock, gigabyte, Asus, msi and the likes who actively make bios and firmware couldn't hack it in regardless of the agesa code, I mean gigabyte boards started supporting it months ago before amds announcement but Asus literally just announced it on certain slots on certain boards even after amd said it wasn't supporting it so I imagine they might keep it going.
