As with the previous page where we tested the NVIDIA SLI scaling between the chipsets, we want to do the same for the AMD CrossfireX. When we decided to run this series of tests, we were able to get in touch with our friends over at XFX and they kindly sent over a pair of XFX Radeon HD 6950’s.
Not only does Aliens Vs. Predator scale well in SLI, but it also scales extremely well in CrossFireX, actually even better. The Intel DX58S02 X58 motherboard is no exception in Aliens Vs. Predator. At 1280×1024 the Intel DX58S02 went from 50.4 frames per second with a single XFX Radeon HD 6950 to 100.7 frames per second in CrossfireX. That’s a gain of 99.8%! At 1920×1080 we started out at 37.9 frames per second and jumped to 75.4 frames per second in CrossfireX for a gain of 95.8%!
Metro 2033 and the Intel X58 chipset don’t seem to play well together. All of the Intel X58 systems we have tested have seen gains in the single digits. The Intel DX58S02 fits right in with our other X58 systems. At 1280×1024 we saw a gain of 1.72 frames per second or 5.9%. 1920×1080 was slightly better we saw a gain of 3.4 frames per second which is an increase of 12.8%.
In S.T.A.L.K.E.R.: Call of Pripyat the Intel DX58S02 did a significantly better job in CrossfireX than it did in SLI. At 1280×1024 we jumped from 104.4 frames per second to 151.8 frames per second for a gain of 45.4%. 1920×1080 we started out at 73.1 frames per second and jumped to 117.1 frames per second by adding in our second XFX Radeon HD 6950. This is a gain of 60.2%.
