Tegra will do just fine as the all in one solution for a portable device. These portable devices don't need to be powerhouse systems.

When you have a screen of 400-something x 280 something and are rendering games at that resolution, you really don't need anything better than Gerofce  6

I haven't seen much concern about the performance. It is fast; much faster than the 3DS will be. The issue is power consumption and related delays. The Tegra was claimed to have hundreds of design wins, then 90% of them never materialsed for that reason.

Even then, if the PSP2 doesn't have glasses-free 3D then it may well lose the graphics 'war' too (not that it makes much difference to sales). But that's not related to the choice of graphics chip.

Speed is still technically up the air, as we don't know what CPU 3DS uses (likely ARM11 or Cortex core, but not confirmed and no clue about clocks), but Tegra 2 does employ a more advanced shader architecture (OPGLES 2.0 vs 1.5 for PICA200).

One big question I have with a Tegra 2 core is what happens to backwards compatibility?  Is it capable enough to emulate PSP1?  Will Sony stick a PSP1 core on the system somewhere similar to the PS1 SOC in fat PS2s or EE GS in early PS3s?
