Is it 128bit or 96bit?

I think I remember reading something that said everything in R3xx is 128bit except the Pixel Shaders.

Only the pixel shader are FP24. Everything else is FP32.

Not only is everything eslse 32, Bt i think that they even store the FP24 data in Fp32 IEEE 32 format at certain stages...

I think it means this:


What, (FP24 that was) padded (with nothing in order to claim it was FP32)? :D

Just a thought. :p

So on NV3X. is it only the Pixel shader being hacked down to fp16 fx12? and everything else is still at fp32? or is there more to it?
