JPCSP Official Requirements?

JPCSP Official Requirements?
According to this:
Wikipedia Wrote:The PSP uses one 333 MHz MIPS32 R4000-based CPUs, a GPU with 2 MB onboard VRAM running at 166 MHz, and includes 32 MB main RAM and 4 MB embedded DRAM in total.
http://en.wikipedia.org/wiki/PlayStation_Portable
But as seem on PCSX2, as more demanding the game, then powerful resources are needed for a proper JPCSP emulation. In that order, i don't get how is that some games (Demanding ones) on JPCSP need at least 3GHz CPU to get 30/60 FPS since a PSP CPU work at 333 MHz.

In my case for example, i own an Quad Core AMD A8-3510mx running 2.5 GHz at turbo speed for each core. Sometimes 2.5 GHz is not enough to get 30 FPS. God of War for example, ran at 10-15 FPS with that speed; if i overclock my CPU to 3 GHz then GOW got a speed boost getting 25-30 FPS. I guess this subject speed is because my video card since it is ATI and everybody knows the problem between JPCSP and ATI. For sure gid15 is making a great work to fix ATI bugs, like on r2684; however, a 3 GHz CPU to run a game that work on his original console under 333 MHz CPU and 166 MHz GPU is kind of wrong.

So, my point is: Why emulators and on this case JPCSP needs 9x or 10x times the original specs of their native consoles?
