The XBOX's 733 MHz Pentium III processor and 233 MHz nVidia NV2A (Geforce 3) Graphics card is powerful enough to emulate the PSP at full speed? I'm impressed.

I tought so, but here http://www.ppsspp.org/development.html it says it it possible, while the PS2 lacks of ram and has weak CPU, so i will try to see what happens...

Basicly anything that's higher in specs as the PSP

Integrated or Support Chips:
IDStorage Keys: stores screen brightness, volume, region, date, time and BIOS data also known as the Ipl
Tachyon: version information for CPU, Media Engine and Graphic Cores
Baryon: version information for the PSP's system control chip
Pommel: the PSP's GPIO and Watchdog
Kirk: the PSP's main encryption processor
Spock: secondary encryption processor, used to decrypt signed UMD data

would potentially be able to Emulate the PSP, though that depends on the target plattform, code speed on it and the code in general (optimization).
Though it also Depends on in-depht-architecture of the Modules themselves. I highly doubt though that Sony went out of their way to invent anything exceptional.

I also saw an article where it benchmarked a 1.4 ghz Pentium 3 and an Iphone 4S, and the winner was the Pentium 3 by a little, but also the Pentium 3 is x86 so it will be faster...
