HardOCP managed to get their hands on some benchmark slides from Nvidia, showing the power within the upcoming GF100 ‘Fermi’ based video card.  While HardOCP didn’t run these benchmarks themselves, so they probably lack customizations & performance tweaks that bring the AMD counterpart to a slightly closer match, the comparisons are startling.  Just check out these two charts for beginners:

That’s a 4x performance boost in geometry shaders (tested by using 6 cubemap environment maps in a single render pass), and roughly a 1.5x-2x boost in framerate in the Unigine benchmark.  See the rest at their site.
