Also, for running DL models you don't need dual CPUs unless you have 8 GPU cards. Finally, Threadripper 2950X provides much better price/performance ratio than either of those Xeons.
No a Threadripper 2950X core does not have the performance of Xeon Gold 12/24 - because Intel has at least 50% more performance per core than AMD, plus there is two Xeons. Plus you can go up to 28/56 Xeon - and this does not even take account these are Engineering computers and likely will use AVX 512,
Intel to have 50% more performance per core than AMD? Any benchmark as a reference for this claim? I would find it unbelievable especially with OS/BIOS/microcode patched to fix Intel's vulnerabilities...
Well that is an estimate and depends on which test - but equal amount cores performance are significantly higher on Intel. Also keep in mind these are new Xeon and they have the Vulnerabilities fix in hardware in a lot of cases.
I didn't find 6136 in comparison - but I did find 6154 - but keep in mind the 6136 is a year old cpu and in Lenovo setup will have two of them.
p1esk said "price to performance" which the link you posted clearly shows. Those benchmarks show a $900 chip performing almost as well as a $3800 chip. AMD is the clear winner in price to performance, which means Intel is only relevant in the most expensive bracket. AMD chips demolish Intel chips at the same prices.
There is a lot more than just x86-64 instructions that make it up a CPU. Xeons have AVX-512 bit while last I heard that AMD has 2 128bit combine together for make AVX2. There are other abilities in that AMD chips don't have like support up to 4 CPU';s
You shouldn't be looking at features in isolation. Yes, Zen is underpowered in the FP departament, but it's still holding up pretty well. And with Zen 2 they will double the DP throughput. And while AVX-512 double the theoretical throughput it also brings (1) down the clock rate and (2) needs software written with AVX-512 in mind to make use of it. Also, Ryzen processors generally have core count advantage at the same price which will compensates for the lower FP throughput. The core count advantage will probably get even bigger with Zen2 - 16cores for the desktop and 64 cores for HEDT! Although I don't claim they will have these core counts at launch. Why do it, when intel cannot come even close. Better to roast them slowly.
As for 4 socket configurations - how many cores can you fit in this way. I'd assume it's like 4x28 =112. With Epyc 2 you will be able to get 2x64=128. You'll have less memory bandwidth 4x6 vs 2*8 but how bad that hurts will depend on the actual workload. There's one thing you can be certain about - it will cost you a small fraction of the cost for intel's 4 socket configs.
But really, my favorite is the Threadripper platform. Last year I got the 12 core TR1920X + Asrock X399 with 10G Ethernet adapter on board for 700 UK pounds total. Total! And I have 3xM.2 NVME slots + 2xPCIex16 + 2xPCIex8 and you can use them all in their full capacity. Plus a 4-wide memory controller that supports ECC. And either this year or a bit later down the road I will be able to replace the CPU with a 64 core beast. Damn, I can plug in a 32-core one right now if I need (and I'm mostly running Linux so I won't be hurt by the inadequate CPU scheduler in Windows). Really, for my money, intel do not exist at the moment.
Considering that the two graphics cards alone will cost close to $10k, it's probably not a stretch to think the entire system will actually be pushing toward $20k.

Titan RTX ($2,500) has the same specs as Quadro RTX 6000 ($4,000), the only difference is ECC support, which is irrelevant for DL tasks.p1esk - Thursday, March 7, 2019 - link

But if you include AVX 512 in picture, Threadripper has no chance of all.

great summarycompletely agree
Intel HEDT at the moment is a waste of $$$
you can of course add to your comments that Zen5 will be drop in for Threadripper also

Depends what type of DL you are doing Reinforcement Learning is very CPU heavy as a lot of environments don't lend themselves to GPU simulation.Valantar - Thursday, March 7, 2019 - link

Yeah, comparable same specced windows lenovo p920 costs around $30k and windows tax is not that high.https://www.lenovo.com/us/en/think-workstations/th...
