Threadripper, PCI Express, and multiple GPUs

Quartz · 13 Aug 2017 at 17:49

Paging @Kaapstad !

One of the plus points of Threadripper - and Epyc - is the large number of PCI Express lanes. I would like to see someone test the effect of this with multiple GPUs, both Radeon and Geforce, in 2, 3, and 4 card configurations. I suspect that there will be a modest difference but I'd like actual numbers.

I tried all this time ago can try to post up tomorrow. It's very easy for me to run again.

I didn't know earlier CPUs and chipsets supported so many PCI Express lanes.

Obviously Intel X Chipset has supported four GPU's for many years.

The Intel CPUs have never had 64 PCI Express lanes with x16 support, have they?

But if you could post a link to your results, I'd be most interested.

I'm having zero problems with my SLI Titans in games.
