To those trying to prove the power of one system against another, using pics/vids is not a very good reasoning. Why? Because the PSP is a generation ahead, and there is good chance that the game engines used to build them were more optimised than their PS2 counterparts.
I have not looked too much into detail with this, but I came up with some figures:
PS2: 6.2 GFLOPS
PSP: 5 GFLOPS
There could be more to these figures then I found, but as far as floating point calculations go, the PS2 is still slightly ahead.
