A cpu for 4 way RTX 2080

[JakePeralta]

Hi!

Im looking to buy a cpu for a pc that will use 4 gpus of RTX 2080.

These are the options I came up with. which one should I take (or a different cpu):

Intel:                        Amd:

i9-7940x                  Threadripper 2950x            

i9-7960x

i9-7980xe

[JakePeralta]

Thanks in  advance

2950X. You wont be able to run 4 rtx 2080's in nvlink sli btw.

Yea I know but it's fine.

First: Thanks:

Second: Can you explain the reason you chose that?

Nvidia doesn't support more than 2 cards in SLI for RTX series the last series from them that supported 4 way was I believe Maxwell which is GTX GTX 980, 980ti and Maxwell Titan

Its MUCH better value, its 5% slower then a 9960x in mutithreaded tasks but in my region costs half the money. You also get 64PCIE lanes, which would marginally help gpu performance.

Pascal also supported 4 way sli, with the 1070, 1070ti, 1080, 1080ti, titan X (pascal) and titan Xp.

Got it thanks a lot! I will probably go for that

 

I'd like to have sacond opinions as well

This is the third thread you're created on this same topic in 24 hours.  You do know you can just ask more questions in 1 thread rather than scatter 3 all over right?

In this thread he for some odd reason didn't post info he posted before, he stated in his 1st thread that he's using them for machine learning (I guess) ?

I'd also go 2950x. I'd say zen+ is level with skylake-x on single core performance. And it's also a beast on multicore too, very close to skylake-x, maybe a bit behind. But the big difference here is, you get basically the same level of performance as skylake-x, just for far cheaper.

new to here.. Sorry, I'll take that in mind

Yes. I assumed this time that it's obvious since there aren't many uses for a machine with 4 RTXs  since they can't NVlink together

Yes with the "enthusiasts key"

You're wrong, SLI on Pascal was limited to only 2 way, the fastest graphics card that supports 4way SLI natively is the GTX TITAN X Maxwell.

 

OP seems not to be going to use SLI but the cards independently for hardware acceleration, for the PCI-e lanes alone the RT 2950X is by all means a better value but it depends on the software OP will use whether or not investing in Intel makes sense.

Which never made it to the market and died as a promise.

The enthusiasts key was no longer required to run 4 way sli on a supporting pascal graphics card after june 2016. But it was only supported in some applications such as benchmarks.

Im not wrong

Exactly, which was why I originally said Maxwell was the last series that had support for it.

Don't assume, you're expecting random internet people to mind-read you since we have no idea if you know that or what other GP-GPU tasks you're interested in (you're new here, we don't know what your tech-savvy level is).

Easy forum rule to think of:  If you want detailed, quality forum replies, you must give us detailed and quality information from the start.  Otherwise it's vague ideas in  - vague answers out.

Well that's due to the 3/4 way SLI profiles being Hidden/removed from drivers for support and being basically benching only if you want to do that.
