well lets see about pipelines in Nintendo consoles.
Nintendo 64's RCP: 1 vertex pipe (RSP) and 1 pixel pipe (RDP)
Gamecube's Flipper: 1 vertex pipe (XF: Triangle Transform Engine) and 4 pixel pipes (or 4 pixels per clock) and the one "4-in-1" texture unit (TEV) 4 filtered texels per clock.
Revolution's VPU: ???? I say at least 4x the pixels per clock that Flipper puts out: so 16 pixels (or more) per clock. maybe 24 to 32 pixels per clock if Nintendo wants higher performance. who knows.
vertex pipes: well both RCP and Flipper had one each, so it's hard to say what Rev will have. maybe one super pipe that can crank out the equivalent of what 8-12 vertex pipes in a Radeon VPU would do. current Radeon X800/X850 have 6 vertex shaders, and R520 reportedly has 8. I'd like Nintendo VPU to have at least 8 if not 12. or the equivalent. (like how instead of seperate TMUs, the Flipper has a TEV that cranks out 4 texels per cycle. maybe Rev VPU will have the vertex equivalent of the TEV.
or maybe instead, the Rev VPU might have unified shaders / unified pipelines like the Xenon VPU. although the 2 VPUs still would not be the same. maybe Rev VPU will be closer to SM 4.0 or maybe not. we don't even know what the basis for Rev VPU is. Is it an extension of Flipper, or is it based more off of R520 or R600 (but still custom and different than Xe VPU) ?
it's easy to speculate. really we have no answers on Revolution VPU unlike Xe VPU which there seems to be quite a bit of info on.
