What's interesting is that if this *is* true, then the strength of the SGX540 GPU may actually be comparable to that of the GPU in the Tegra2 T20. The Galaxy S can run Quake3 at around 40-60 fps at 800x480. I'm not sure what the Tab would do with the higher resolution, but it would likely still be quite high.

Of course, this is dependent on a number of factors (ie. the code base that was running). However, this is encouraging.
