Quad, Hex, Oct, Dec Core or Xeon. Which CPU is Best for a test bench?

post #1 of 4
Thread Starter 
G'Day Guys,

I'm currently in the process of building a test bench separate from my main system so I can test parts and so forth and I'm not sure which processor would give me the best results.

I'm looking at running an x99 platform just in case I might need the extra cores to remove a possible bottleneck from the gpus?

I want the test bench to be able to drive at least 2 high end gpus without any bottleneck whatsoever. I currently have a Titan X that I want to put to use, But would a quad core processor be enough to run two GTX titans in SLI without any bottleneck? What about the infamous Quad SLI/Crossfire? What processors would you guys recommend.

I want this test bench to not just be able to do the basic stuff like check for faulty ram sticks, hard drives and solid state drives, But to see if gpus could be faulty when running sli and single card testing.

How much ram would you guys recommend as well? Would 32gb of ram be necessary or would high amounts be required?

Ideally the cheaper option would be the best, But If I need to pay more to get what I need I'm willing to do it.

What about test benches? Unfortunately in Australia you can't buy them anywhere, I was looking at a few.. Can any of you recommend me any? thumb.gif

Check out this article. It's from 2012 but lists good points for benchmarking in general. I think this would be a good start to answer some of your questions.

So after doing some more research it seems that a quad core is best for 2-way SLI, hex core for 3-way SLI and dec core or higher for 4-way SLI. Of course the amount of PCI-E lanes does play a part in how many cards can be natively supported being 40 lanes being the optimal amount.
Comparing the most current hardware of the time, In other to achieve quad sli, I would need a motherboard that has support for it.. plus a 3930k or higher.

Ideally for the best price to performance ratios, I think I'll go with a 2-way sli supported motherboard.. This should keep costs down and I can just test to sets of cards separately if I need to.

My next question is which generation should I go for? I just managed to get a MSI Z87 MPOWER brand new at a good deal.. definitely enough to make a profit on if I choose to resell. Should I buy an 4670k/4790k? Or just go straight to Skylake? The test bench won't look as nice as I was going for a yellow/black themed test bench.. unless MSI plan on releasing a Z170 motherboard version?

Picture for reference..
