Plus vita plays psp games through emulation and i simply see the ps2 as barely any more powerful than a psp.
That's not really true, and there is more to emulation than just how powerful the console was. It's easier to emulate wii games than ps2 games, for example.
The difference here is that the vita would need to a bare minimum of 10 times the processing power it has to even have a chance of emulating ps2 games accurately at full speed.
Yes. The Vita needs that to run PS2 games at full speed with sound. If you're Sony with a team of professional coders where half-speed is simply not sufficient, then emulating the PS2 on Vita is impossible. But if you're a homebrew dev working without pay and half-speed without sound is considered playable, then it's possible.
Ok, but it's not going to get half speed, even without sound. Maybe
it could do 1/4 speed for some games, but that seems entirely pointless to me.

Do remember that the N64's CPU is 64bit(and so as the PS2) and the PSP has a 32bit processor. Besides, ARM instructions does more than MIPS'. Only downside is it has half the number of registers.
They are still similar cpus, which gives it a huge advantage.
