    Maybe I missed it, sorry if I did, but did you measure the VRM Temps as well? Many boards seem to come with lower quality VRMs and cover them up with heatsinks. But even heatsinks can't cover for low quality VRMs when doing overclocking like this.

    On each of the board pages there are links to their respective full reviews. OC testing there with full 360mm AIO and VRM temps with thermal images.

    Would it be possible to do similar overclocking tests for the Ryzen 5950X?

    Chugging along with my 10900f for the next 8 years i hope.. didn't see any benefit doing overclocking these days. Just have enough core and cache and you're all set.
  • TheinsanegamerN - Monday, August 30, 2021 - link

    I mean if you still use a 60hz monitor, as most do, a sandy bridge quad core can still maintain 60 FPS in all modern titles. Games are nowhere near as intensive as people make them out to be.

    Nah Quad cores are out for gaming.

    Quad cores can still hold 60 FPS just fine with an AMD GPU, while rarely dropping a few frames below 60 on an RTX 3090. I’d say quad cores are still good enough for gaming for a few more years.

    You will play 1080p with rtx 3090? Also this is Skylake, Sandy will be even lower
  • TheinsanegamerN - Thursday, September 2, 2021 - link

    >literally every game has a 1% low higher then 60 in all tests except the slowest core i3 in tomb raider

    Please explain how this makes them “out” for gaming? Seems they’re holding up really well.

    I just upgraded from my 10~ year old Core i7 3930K Sandy Bridge CPU, 6-cores, 12 threads. Overclocked to 4.6Ghz with 16Gb of Quad-Channel Ram...

    Haven't noticed much of a difference when upgrading to the Ryzen 9 5900X and 64GB of 3600Mhz Ram in the games I play. (Mostly just eSports titles)

    But hoping this rig lasts 10~ years like my last one.

    Sold my old system in parts and so far made about $1,000 AUD back, which is definitely a good return on investment... Enough to buy a Radeon RX 6700XT.

    Buy Apple Silicon. Pretty soon, no amount of energy-wasting, environmentally unfriendly overclocks can match the speed of a 35w Apple Silicon thin and light Macbook Pro.

    My sides have entered hyperspace. How can one be so dense?
  • bigvlada - Monday, August 30, 2021 - link

    That's what we were hearing about slow and melting Pentium 66 MHz and lightning fast and cool 90 MHz PowerMac.

    And no, "This time it will be different tm" won't work, because just like in 1984. and 1994. majority of people do not want a closed, barely repairable system. In those early days, you needed a bayonet sized screwdriver and soldering iron in order to expand memory on Apple machines.
  • joelypolly - Monday, August 30, 2021 - link

    I mean... look at the smartphone market. It's a good indication that the market has changed and most people are just looking for a computing appliance.
  • M O B - Monday, August 30, 2021 - link

    Oh really. Do people normally want to swap out the GPU, RAM, disk, or WiFi/BT card in their android phone? Of course now. Phones, despite their computational power, are not computers. You fail at analogy.
    Every company except Apple at least makes it possible to swap out several components, granted that soldered RAM or PCIe SSDs are common in certain compact form factors.
  • vshade - Tuesday, August 31, 2021 - link

    Smartphones are computers for most of the world, is the device they will communicate, make planning and game on.
  • whatthe123 - Monday, August 30, 2021 - link

    It's an indication of an entirely new premium market that relies on subscriptions to mask costs. Macs continue to dominate in profitability but they always trail in marketshare because the upfront costs are too high, and nobody can really even get that market except Apple since Apple is the only one that has successfully created and maintained a lifestyle culture around their products. In order for Apple's CPUs to sweep the rest of the market they'd need to sell their chips directly or macs would need to overtake everything else in volume, neither of which Apple seems interested in doing or is really able to do since they're capped by TSMC's output.
  • Exotic - Tuesday, August 31, 2021 - link

    On Desktop I agree as people generally want easy upgradability. Where Apple Sillicon will shine and be very impressive to a lot people will be in laptops. In 99.99% of laptops the CPU and GPU is soldered and is not user upgradeable and the same is to said for ultrabooks regarding RAM as that too is getting soldered onto the mainboard.

    Laptops also sell more than desktops these days.
  • Wrs - Tuesday, August 31, 2021 - link

    Being closed and barely repairable is a side effect of tight integration, not necessarily with being Apple. It is true that Apple tends to be associated with pushing the curve on engineering/miniaturization and naturally this results in a higher price, but they don't have a monopoly on integration and neither does the PC side have a monopoly on expansion and the use of commodity parts.

    I remember Macs from the 90s, as well as Mac Minis in the 2010s that incorporated tool less entry to the RAM slots, and with just a few regular screws you can access the same on Intel iMacs. Hard drives were just more screws. That's leaving aside the Mac Pro lineup. Yet no modern smartphone lets you upgrade the RAM or internal storage because it takes a lot more effort to design user serviceability into such a tiny yet functional form factor.

    424 W under peak nT overclocked load. Those VRMs were earning their stripes!

    53W per core. Per core!

    Is there a reason besides voltage why Chip #3 significantly beat Chips #1, 2 in POV-Ray + Cinebench R23 nT + GB5 nT on the Z590 HERO ? All were 5.2 GHz. Higher voltage = better clock stability?

    //

    Is it a typo or a really good deal on the first page chart at the bottom—i9-11900K to be $374, though earlier written as $545.
  • ceomrman - Monday, August 30, 2021 - link

    This is a great article, nice work! The gains are very modest, but more surprising to me was how variable they were. As a consumer buying top-shelf parts, you could easily end up with worse overclocked performance than you'd get at stock settings with a different random CPU and/or expensive, high quality motherboard. Even for uses that would benefit from overclocking, there are very specific configuration choices to navigate. That's not to mention that the kind of tasks that would benefit from absolute max multi-core performance are noticeable faster on a Ryzen or even on older Intel HEDT chips with more cores, anyway. The 11900K is for gaming. Overclocking it yields no gaming improvement. So yeah, don't bother.

    > full duration, 10 hours a day over 300 days a year equates to an extra $41 in energy bills.

    Please specify what figure you're using for "current average US energy prices". They vary by a lot (in terms of location, time of day (for some), and time of year).

    Also, it'd be worth noting that you're not taking into account additional A/C costs. During the winter, some might not need air conditioning, although electric heat is nearly always more expensive that gas or oil (making this an inefficient substitute). However, during the summer, if the A/C is already taxed, the marginal increase in power utilization is probably nonlinear.

    Although this sort of matrix testing sheds a little light into variations between boards and CPUs, you should probably use multiple samples of each board to draw any strong inferences about them. More importantly, I think a greater number of readers would be better-served by doing a proper GPU review.
  • mode_13h - Monday, August 30, 2021 - link

    BTW, when estimating energy costs, did you account for PSU losses? If we assume the PSU is 80+ Platinum and running near full-load, it'd amount to another 11% or so.
  • TheinsanegamerN - Monday, August 30, 2021 - link

    "The average electricity rate is 13.19 cents per kilowatt hour (kWh)."

  • Dug - Monday, August 30, 2021 - link

    "map provides a good representation"
    Well every site has different averages, so it's misleading.

    And most are done by location, not by population. So 100 people paying 9cents and 1 million paying 13cents averages out to 11cents. Which isn't a realistic average.
  • mode_13h - Tuesday, August 31, 2021 - link

    I typically pay about twice that.

    And if we consider the case of Texas, they typically have lower energy prices. However, during peak-demand season, the spot price really shoots up. During the summer, A/C is so essential that people there will cut back on food expenditures before they completely forego air-conditioning.
  • Wrs - Monday, August 30, 2021 - link

    Or you could back-calculate what kWh rate they were assuming. I suspect a miscalculation somewhere by the quoted… In any case, a TEC is horribly inefficient for substantial active load, and in this case rather ineffective due to being undersized. 200w for 88 C at approx. 300w heat load? Just get a faster water pump to beat that with ambient liquid cooling. Electric cost would be pennies on the dollar!
  • thestryker - Monday, August 30, 2021 - link

    It sure seems like some sort of adaptive core overclocking would be key on these processors. On my 6800k, and now 6900k, I definitely have my overclock set for 2 and all cores just to keep the voltage down, but gain extra clockspeed for lightly threaded. It's not perfect, but assuming this type of setup works on z590 properly it would at the very least keep that stock boost if not allow for higher.

    In general from what I've read regarding both AMD and Intel's recent processors though it just seems like overclocking for a daily driver just isn't particularly worth it. Maybe with the upcoming ADL there'll be something extra to squeeze out of the E cores, but otherwise the future sure seems like minimal OC gains.

    ‘If Intel's Turbo Is So Good, Why Manually Overclock?’

    Unless you’re a professional overclocker (a salesman for companies that profit from the overclocking business) it’s a waste of time and money. There can also be the risk of tinnitus if noise levels are pushed too far.
  • mode_13h - Tuesday, August 31, 2021 - link

    Tinnitus is definitely an occupational hazard for those who spend lots of time in server rooms! However, I would hope that gamers don't often push air coolers that far.
  • Oxford Guy - Tuesday, August 31, 2021 - link

    You’ve not heard of the delta fan braggers of yore.
  • Oxford Guy - Friday, September 3, 2021 - link

    And, of course, the aggravation of an existing tinnitus condition is easy to accomplish even with ‘silent’ hardware (like the Seasonic ‘Snow Silent’ PSU that a reviewer here said could be heard from rooms away).
  • MDD1963 - Monday, August 30, 2021 - link

    I understand the GTX1080 is/was a popular card to this day, but, if when illustrating lack of differences among CPUs and mainboards at 1080P, I'd perhaps at least choose a GPU a little higher up the performance bracket to maximize potential CPU scaling. Doesn't have to be a 3090 to placate the 10 folks who actually own them. Perhaps a 3070 Super or 3080. :)
  • Frequensee - Tuesday, August 31, 2021 - link

    Yeah it’s like using an RTX 2060 for CPU testing, it doesn’t make sense.

    well not been back to this site for weeks due to its obvious roots as an Intel marketing tool and what do I find?
    The front page is dominated by Intel news one little measly mention of AMD and a main article that frankly is about as relevant as a Bicycle for Fish, just how many of your readers do you think actually do this on a daily basis as opposed to use a PC for other stuff, once again the Marketing Dollars are very much in abundance, shame on you for even suggesting your still a journalistic site.
  • mode_13h - Tuesday, August 31, 2021 - link

    Intel recently concluded their Architecture Day. So, there will naturally be a number of articles about Intel tech & products following that. Would you rather Anandtech not cover it?

    If you want to see more broad & diverse coverage, check out their Hot Chips liveblogs.
  • Wilfred86 - Tuesday, August 31, 2021 - link

    Another Intel promotion piece. It should say "advertorial" on the title. Why on earth would you want to overclock an abomination of a cpu that already takes 300 Watts at stock? I know it's stated in the article, but this is so far today removed from everyday reality is not even funny.
  • Samus - Tuesday, August 31, 2021 - link

    That's a whole lotta work for a whole lotta nothin'!
  • watzupken - Tuesday, August 31, 2021 - link

    424W!!! Goodness me. That is almost like adding Intel's TDP number on top of the 300W that it can potentially pull at full tilt. In my opinion, for the cost of pulling off this overclock, one is better off buying a Ryzen 9 processor. In cases where more core matters, you just can't beat an extra 4 cores on the 5900X or 8 cores on the 5950X.
  • Foeketijn - Tuesday, August 31, 2021 - link

    A very long time ago I bought a crate of Socket A Mobile Bartons for peanuts. 6 or so. They could run a 400 fsb instead of their default 266 No locked multipliers (untill 12) .A tiny bit more then the top level Athlon XP. just 75 Watts. And almost double the performance. Quake never went smoother. Those where the days.
  • Oxford Guy - Tuesday, September 7, 2021 - link

    Except that they would catch fire, as I recall. No automatic thermal shutdown feature.

    Great for showing that overlocking is long gone. This is not exclusive to Intel, even AMDs and Nvidia's latest parts have little headroom. One is better of finding a good undervolt with today's latest hardware because it allows longer boosts, lower power consumption, noise, and heat.
  • Wrs - Tuesday, August 31, 2021 - link

    All this stuff gets better headroom with better cooling. Unfortunately the TEC here is one of the worst implementations. 88C is the evidence for all that work. The TEC is at least silent. Here it is a TEC combined with liquid cooling. It would be far more effective to use a chiller with plain liquid cooling. Most effective and technically demanding would be phase change refrigeration directly on the CPU IHS.
  • Spunjji - Tuesday, August 31, 2021 - link

    TECs are pretty rubbish for this particular purpose, but I think it's the best Intel could do for a "retail" product. It's just a cataclysmically bad idea all-round.
  • Oxford Guy - Tuesday, August 31, 2021 - link

    ‘Great for showing that overlocking is long gone.’

    I’ve been saying that for some time and, humorously, someone posted a massive rant in response the last time.
  • Spunjji - Tuesday, August 31, 2021 - link

    Cooling a 400W load with a 200W TEC just seems like a bad idea. It would have been nice to have a more explicit front page heads-up - and maybe more prominence in the wrap-up - that this cooler isn't fit for purpose even with a *stock* CPU.
  • velanapontinha - Thursday, September 2, 2021 - link

    Can't believe people still go through all this hassle just for an uptick of less than 10% performance...
  • Flying Aardvark - Tuesday, September 7, 2021 - link

    Team Clickbait on Youtube panned the 11900K, but given the silicon bugfixes (finally) from Skylake, and the IPC uplift.. I'm loving this chip. Under warranty it holds 5.1GHz on all cores, never dipping in games. And with other default BIOS settings (MCE enabled), I've seen 5.3GHz on 7 of 8 cores simultaneously, nearly all the time in desktop use. It's very snappy and responsive compared to my 5900X- contrary to public opinion.. as I have both.
