Gigabyte GTX560 Ti SOC
Unigine relies heavily on two things. Incredible GPU power, and as many driver tricks and tweaks as you can employ. For power it's clear that the GTX570 has things well under control and dominates proceedings for nVidia. AMDs focus on achieving incredible scores when Tessellation is employed clearly reaps massive benefits here. Between the two GTX560s the SOC is once again kept at bay by the overclocked reference design.
With the anti-aliasing set to 8x the results from above are mirrored, such is the robustness of the Unigine benchmark.
We do see the first occurrence of that strange phenomena where you're at the silicon limits and things perform worse from the overclocked SOC though, dropping down to 6.8FPS minimum.
