Multi-GPU - GTX 980 SLI and R9 Fury Crossfire

Multi-GPU gaming - GeForce GTX 980 SLI and Radeon R9 Fury Crossfire

So we dealt with most possible scenarios game performance wsie, aside from Multi GPU gaming (SLI and Crossfire). The GeForce  362.00 WHQL driver already was SLI compatible. AMD today released the AMD Radeon Software Crimson Edition 16.2.1 Hotfix driver (download) which enables Crossfire gaming. This results into a very  interesting outcome. Let's have a peek.

Above you can see the Radeon R9 Fury x2 both measured as single card and in Crossfire.You'll notice that at 1080p we see negative scaling, we see it often with AMD cards, this is CPU utilization related. At QHD things get more GPU bound.  However we see some excellent Crossfire scaling in Ultra HD. I didn't see that one coming, as it really is terrific. We'll show you the absolute number lower on this page.

SLI then, we take the GeForce GTX 980, again single card and SLI (2-way performance) At 1080p to 1440p you'll get roughly the same performance, again a CPU bottleneck, however at 1440p we see pretty decent scaling. Ultra HD all of the sudden becomes playable as well. So let's plot that in average frame-rates (on the next page we'll zoom in at Multi-GPU FCAT as well).

Yes, at 2560x1440 the 980 SLI combo rocks hard where the Fury seems to be struggling. But now let's move towards Ultra HD:

Look at that, that's a pretty staggering difference considering both cards have 4GB of graphics memory. We see it often, AMD Fiji based graphics cards get stronger in Ultra HD.
