I just downloaded the latest version of the PhysX SDK the other day, and toyed around with it a bit.
The froggy sample runs at 22-25 fps on my E6600 with 3 GB of memory.
Sadly there are no fps visible in the Youtube movie, but by the looks of it, it runs well faster than 25 fps on hardware.
Ofcourse the biggest advantage of the PPU can't be seen here... In this sample we're using the full CPU power for physics alone. In an actual game, we'll be needing a lot of CPU-power for all sorts of other things, so the effective physics performance would be much lower... The PPU is dedicated to physics, so it doesn't care what the rest of the system does, it will always have 100% of its time to spend on physics.
