Currently, PSVita has a 4-core SGX543MP4+ GPU (133MT and 1000MP fill rate, DX9 and OGL 2.1 support) and a 4-core ARM Cortex-A9 MPCore CPU, the PSVita2 (working title) is believed to implement a 4-core G6400MP4+ GPU (380MT and 5000MP fill rate, DX11 and OGL4.2 support) and a 4-core ARM Cortex-A15 MPCore CPU, that's almost 5X the raw power of the current PSVita. I'd wait for that one to come and skip this entire generation of PSVita ....
