Not only that but being such a big product (both literally and figuratively) i thought it deserved a spot on Anandtech's home page as well? Pretty poor form IMO.
Since this is a server chip, I highly doubt we will see mATX boards. We may not even see ATX boards, as these will mostly be used in workstations/servers.
Wow. Really? You're going to complain that someone shouldn't use a word and then point to a definition that greatly substantiates it's use as the name for their product? From UD: "Epyc is a descriptor for something of remarkable high quality even among the highest quality works. It is most easily defined as being an intensified version of the word epic."
Maybe look before you leap. "Phat" on the other other has gone out of style, come back and is now on it's death bed. Also "epic" isn't a term, it's a word. In the immortal words of Samuel L Jackson: "English, Motherfucker! Do you speak it?"
I love it. I love my Ryzen CPU. I couldn't justify waiting or paying for Threadripper but I am absolutely loving the fact that AMD is back in the game. I never thought I'd see the day.
I have a Ryzen system and so far the stability of mine has been better than the Phenom II 955 it replaced (have a 1700X on an Asrock X370 Fatal1ty Gaming stock cpu with 2400mhz 32gb ram)
my 1800x is totally stable. There are some wake-form sleep annoyances with windows 10. once a week it just wont fucking wake from sleep and i have to restart it. I believe that has to do with my motherboard, however. not the cpu. motherboard is msi gaming pro carbon ( i dont recommend it ). I paid 70$ for it.
Years ago i used to get wake from sleep issues on an OEM box, found it to be dirty power coming out of the wall. Connected the computer to an APC ups and never had a wake from sleep issue again. So that may not even be tied specifically to the motherboard or the processor, could potentially be the power supply.
Hey guy, I have a Ryzen 1800x. with 3200mhz Ram. My Ryzen seems to be very very stable. Just 1 lock up so far during Rise of the Tomb raider. Just once though. Love the Ryzen!
The 64 bit computing as we know it today, was given to the masses by AMD. AMD took one bit and now it is giving back a hundred. If that is trolling, let it troll. Go AMD, Go!!!!!!!!!!!!!!
I saw that. I am wondering if Intel will have a X399 platform in the future. Going off the 990FX it should have been probably called 399X or something. Going to be confusing to the consumer at any rate.
Just because you need more than 6 or 8 cores doesn't mean higher clocks aren't important. It's just means the CPU would be capable of more work per core.
16-core clocks are always lower, but isn't Ryzen actually more power efficient than Intel (as long as you don't get too close to the ceiling at 4.1GHz)? So the 16-core clocks might actually be higher on this than on Skylake-X. You'll still get your single-threaded performance, thanks to turbo clocks, but as soon as more cores start to work the clocks will go down. Ideally, this will give you the best of two worlds (high single-thread and multi-thread performance) in one product.
Well AMD's move with ThreadRipper forces Intel to show their superiority with higher clocks, hence why Intel didn't yet announce the clocks for HCC parts waiting for AMD's move first.
Correction, HCC was enterprise-only before, if you've read Intel's Skylake-X recent announcement right here on Anandtech you would've seen that Intel included HCC parts to HEDT as well, that's why I'm saying Intel is waiting on AMD to show their cards first before they reveal their clocks for the 14. 16 and 18 core Skylake-X CPUs.
So the fight will be most likely be more PCIe lanes vs higher clocks, whichever suits clients better.
The OP said people worry about the clock speed and ST performance. My reply was to that. If your use case needs clock speed and ST performance, the an HEDT isn't for you. They tend to be clocked lower a good bit. A 4 core speed demon would suit you better. Of course everyone wants more cores, more speed, more cache for less money. That's a another story all together and not the point. ;)
I have a feeling that the size is mainly because of the PCI-E lanes. Even a 16 core processor should not be that big. At least they can (relatively) easily upgrade the cpu to 32 or maybe even 64 core cpu.
Indeed, and having 2 dies also has other disadvantages (not to mention that each die is already 2 "modules" internally), I wonder how it fares against Intels real 16-core die.
Intel's larger chips have three modules internally, connected by a ring bus. 6 core module * 3 = 18 cores. So the architecture is a little different, but they have the same sorts of issues.
"real" 16core die is a misnomer. theres a tradeoff in using MCM vs. monolithic. I'd argue that MCM offers quicker time to market and while there are certainly latency advantages to monolithic dies, you don't get the advantage of n-scaled cores as easily. cost, performance, ROI. MCM handily beats unified dies at scale.
bias? I'm not stating things one way or the other. simply arguing that MCM, in today's world, is much easier to fab, assemble, and sell. cuts the cost dramatically on a per processor assembly cost basis which in turn affects ASPs and company revenue. how is that biased?
Love, love the Intel-trolling that AMD is up to. Funny how Intel showed their Skylake HEDT chips with the usual marketing-led gimping/segmentation as a response to Threadripper and now Threadripper one-ups Intel's response to itself. Looks like the engineers are finally having fun at AMD.
Glad to answer that. The Intel story was a fully pre-briefed embargo with lots of news, technical reveals, chances to ask questions, etc. Whereas this news comes from a Computex press conference and AMD only announced 2 things about ThreadRipper, both of which we could already infer from Epyc: 64 lanes of PCIe, and quad channel memory.
It will depend. AMD has very strong SMT and multicore scaling. There are some tasks where 1800X 8 core is trading blows with the Intel Core i7-6950X (10 core chip). And the difference between 16 and 18 cores is even smaller.
One thing is certain those who need 16 or 18 cores will care about multithreaded performance, and AMD is very strong there. Not to mention the price/$$$ disparity.

Can someone confirm the tdp of 16core EpIc processor and if an matx motherboard will be manufactured ? (Because that cpu is huge) :)Ryan Smith - Wednesday, May 31, 2017 - link
The TDP has not been announced. As for mATX boards, we'll be crawling the Computex showfloor to see what has been announced.davegraham - Wednesday, May 31, 2017 - link
TDW is ~155w for the 16c/32t part. roughly 75w per MCMclose - Saturday, June 3, 2017 - link
Ryan, quick question since I can't find any previous reporting on this topic. Why is this getting coverage 2 weeks after being announced?Arstechnica covered this on 17th of May. Did Anandtech also report and I missed it?

4 DIMM slots, 2 PCIE slots.Yes it's doable since the boards don't need a Southbridge chipset/hub for peripherals.

PixyMisa - Wednesday, May 31, 2017 - link
They share the package with the 32-core Epyc CPUs.davegraham - Wednesday, May 31, 2017 - link
but are lacking the SoC features of Epyc. hence the need for a southbridge (e.g. X399)aryonoco - Wednesday, May 31, 2017 - link
X399... I see what you did there AMD.I'm loving this. Finally some competition in this space.
I hope they price Threadripper at or below $999. Sure the IPC will be lower than Skylake-X, but that will make for one interesting comparison.
Alistair - Wednesday, May 31, 2017 - link
Same IPC, perhaps 25 percent slower clocks and single threaded is what worries people.Manch - Wednesday, May 31, 2017 - link

> So the 16-core clocks might actually be higher on this than on Skylake-X.There's no chance of that happening, Intel has superior fabs and more mature node which translates in higher clocks
Gothmoth - Wednesday, May 31, 2017 - link
but the intel DIE is denser packed and smaller overall so it has to dissipate more heat over a smaller area too.... it´s not all that simple you know.i doubt it will be higher too, but 16 core skylake-x will be HCC and they are not famous for high clocks either...

64 PCI lanes is awesome but the catch is no doubt significantly slower clocks around 3.2Ghz compared to 3.8-4Ghz of Intel equivalent.PixyMisa - Wednesday, May 31, 2017 - link
If the leaks are correct, the top chips will be 3.5 base, 3.9 boost. Some of the cut-down chips will have slightly higher clocks.3.5/3.9 is great for a 16-core chip.

PCIe lanes number has nothing to do with CPU performance, obviously if you need 16 cores than having 18 will mean more performance overall.sirmo - Monday, June 5, 2017 - link
It will depend. AMD has very strong SMT and multicore scaling. There are some tasks where 1800X 8 core is trading blows with the Intel Core i7-6950X (10 core chip). And the difference between 16 and 18 cores is even smaller.One thing is certain those who need 16 or 18 cores will care about multithreaded performance, and AMD is very strong there.
