I dont know that much about the processors in GPUs, but I think there are
two kinds of instruction sets, pixel shaders and texture shaders. One is
very limited and one has a resaonable subset of C + libm. I can't remember
which is more capable, but its the set standardised in OGL 2.

"BionicFX has announced Audio Video EXchange
(AVEX), a technology that
transforms real-time audio into video and performs audio effect
processing on the GPU of your NVIDIA 3D video card, the latest of
which are apparently capable of more than 40 gigaflops of processing
power compared to less than 6 gigaflops on Intel and AMD CPUs."
Hrm, I wouldn't call those FLOPs, since the operations aren't discrete
floating point operations under direct control. Those graphics primitives
are extremely limited in scope to 3D transformations and various
median/anisotropic filtering "calculations". Remember also, that destroying
information is a deliberately permitted aspect of these "calculations".
None of the GPU operations are required to be reversible.
