GF110 GPU Notes

PureVideo HD: VP4
VDPAU: Feature Set C

GF110 has 4 GPCs each capable of 8 pixels per clock. This limits complete GPU to 32 pixels per clock and because of that it can't feed all 48 ROPs when they all require data at the same time.
Additional ROPs however can be used for MSAA (because it doesn't require additional data from rasterizers, while giving more work to ROPs.)

The complete die contains 64 texture address units and 256 texture filtering units.
