Where can I actually buy EPYC CPUs?

I'm looking to build a EPYC based rig for CAD / rendering / video work. I have been eyeing a supermicro H11DSi motherboard and (2) EPYC 7351s.

I am used to buying components from newegg / amazon / ebay / [H]. I have never purchased server components new. Are there any good distributors to look for? I looked through some suggested server supply distributors on supermicro's site and I have never heard of any of them.
Thanks.
 
Even more PCIe lanes, upto 128 from a 1p or 2p Epyc system, and double the number of cores per cpu

Why Epyc? Isn't Threadripper enough for those jobs?

ThreadRipper tops out at 16c/32t. Ideally I'd want to be at 18c/36t or higher. I'm not the OP but like the OP I'm going to have similar requirements.

In about two weeks you can get a 7980xe.... I'm waiting on a major price drop. 2k is way retarded. I can almost get me a decent LaRue Ar15 for not much more which id rather have lol.

Word is that there could more cores coming to TR too, at least that's the assumption. It is buried in the story about AMD's skunkworks team regarding TR.

"We will continue to build products for the Ryzen Threadripper Socket TR4 platform"

Intel never drop prices. Also, the Epyc chip will have 3x more PCIE and use less power.

Maybe but when looking at how they originally planned it was R series up to 8 core and EPYC for all core counts above. But then came threadripper so not sure if 18c,20c and so on would be TR or EPYC.

That's the point of that story. TR was not planned and came about because of chance. And chances are that there's nothing stopping them from raising the core count or mixing it up some other way. We have JT of AMD on the record saying they will release more TR products. Epyc is the server line and the SP3 Epyc socket is wired differently so if it's going to be a TR product that would logically exclude Epyc.
 
I'd like to see a socket adapter for a Threadripper board like we had for the Cyrix or something processor back in the day. Need a modded BIOS.
 
Weird thing the two sites on the boards say 1 TB registered on CDW and Newegg says 64GB on the Gigabyte.

I don't see how they can do it, it appears to be Ryzen 1 die for dual channel, TR is 2 die for quad and Epyc 4 die for 8 channel - due to memory controller configuration. Maybe they'll add more cores to a die when zen2 comes about, but I don't see how the memory controller setup would work with more than 2 die in there - you'd have to disable the memory controller on the extra die and you'd run into some funky infinity fabric latency in the die that aren't connected directly to a channel....Epyc can go anywhere from 8 core to 32 core, but it's all using 4 die, 2 core enabled per die for 8, full 8 enabled on each for 32 with all the other configurations in between. Don't see how you can get more than 16 core in TR without a different base ryzen chip.

They could disable one controller per die, and have a Quad-channel Quad-die part..
 
I'm about to get a dual Epyc 7451 system via Supermicro Tower 4023S-TRT using a local reseller. Thinkmate has a decent website to build Epyc systems to get a price estimate on a build before requesting a quote from a reseller.

I guess it'd be easy to test the effects on the 4 cores without the memory controller by putting all the memory on one channel on an R7 (or all the memory on 2 channels of a TR). I have a feeling there'd be some latency issues on the cores that had to jump the infinity fabric to get to the memory controller, but yeah, it'd probably work.

#Preach. The more threads the better. I have been using a workstation-replacement laptop and it just blows for solidworks / keyshot rendering. There was a 6hr render that just pushed me too far and now I'm trying to build a rendering machine with the most bang / buck.

You can also buy them from CDW. Here: https://www.cdw.com/shop/products/AMD-PS7281BEVGAAF-EPYC-7281-16-CORE/4779261.aspx?enkwrd=amd epyc&pfm=srh

Thanks! Yeah, I have been looking at the EPYC chips on some vendor sites and I am honestly surprised at the variance in price on just the chips alone. Not only are all the retailers about $100-200 off from AMD's stated retail price, but the number differs by 20-80 between vendor. Like what? I'm used to prices being pretty close between newegg / amazon / superbiiz / microcenter.
I also find it pretty humorous how the supermicro dual socket board with 10g ethernet is priced to match the gigabyte 1 socket alternative. I was considering getting the supermicro board and just buying 1 cpu and getting the second later so the cost up front is not so severe, but man it would have been nice if that gigabyte board was 1/2 as much.

Forbes' article is rewriting he history. The original plan was

AM4: dual channel; up to 8-core
SP4: quad channel; up to 16-core
SP3: octo-channel; up to 32-core

SP3 platform is EPYC and TR4 is a mixture of SP3 and the former SP4 platform.

There is no way to get 18/20 Zen cores on TR, just like there is no way to get 12/14 Zen cores on AM4. Each Zeppelin dies has a max of 8-cores and TR4 only supports two dies.

WRONG. BS. IGNORANCE. IDIOCRACY.

So you expect us to believe you over AMD execs and again in leau of any links. Man you have been busy this past week, multiple instances that you don't know shit. You are making it too easy.

Is this the first hint that Glofo will fail on the 7nm node as well?

It's the color of the posts and statements. Sort of the the opposite of Alan Greenspan's term, " Irrational Exuberance " it's "Unreasonable Pessimism" . The basher's only tool. Has anyone ever asked if Juan has ever received any compensation in any form for opining on the plethora if hardware message message boards which he has made a habit of doing for the last year? Truth is often stranger than fiction.

I say the things as they are. You can believe the guys that are rewriting the history. I couldn't care less!

its not a fixed/firm price but a suggested price, MSRP. retailers can charge double if the market will pay it, thats out of amd's hands.

Huh. I didn't know that. I'm so used to paying MSRP or below that it really caught me off guard. I guess server grade stuff can push premiums.
