I want to know how in the world.............???

Question

I want to know how in the world they say that the PS3's PPU is not used and that it is just for backup,let's do some little math and see:PS3's cell=8 SPUs

1 SPU used for XMB all the time=7 SPUs

7 SPUs=6 for games=1 SPU

1 SPU=1 SPU for the OS(operating system) all the time=0 SPU

then there's no backup SPU,where they get that info form?where is the backup SPU?all the SPUs are used for different stuff,all of hemare busy,so tmy question is:where is the backup SPU if all the SPUs are used at all times?

Answer 1

the XMB is actually the PS3's OS... so you've actually allocated an extra SPU there.

Answer 2

The XMB is the PS3s OS.
