NV40 (next Nvidia product) and R420 (ATI's next offering) are sure to be great cards and I think the NV40 has already taped out but what features would you guys like to see implemented in the next gen GPUs? I personally would like the following;
NV40:
FSAA : Nvidia has to really offer at least 6x (even poss 8x) gamma-corrected, rotated grid, sparse pattern MultiSample Anti-Alising.
Pixel Shading units : I hope NV40 will have 8 piplines - each with a FP32 ALU and a second full FP32 ALU per pipe (NV3x has 4 pipelines - each wilth a full FP32 ALU and then a mini-FP32 per pipe).
Pixel Shader performace : Hopefully FP32 will be able ro use the full speed of the architecture.
R420 wish list :
FSAA : Allow x8 gamma-corrected, rotated grid, sparse pattern MultiSample Anti-Alising (more Z-units per pipe are required for this as increasing number of AA samples decreases avaliable Z-fillrate on R3X0).
Pixel Shading units : If R420 has 8 pipelines then - it could have 8 FP24 ALU (vector + scaler co-issue) and a second full FP24 ALU per pipe).
If R420 is 12 pipelines (think 3x RV360) then it could keep the same config as R3X0 - (one Full FP24 ALU per pipe and a second mini-FP24 per pipe).
Pixel Shader precision :
FP32 would be nice. BUT as it is likely that PS 3.0 will only require FP24 then R420 may stay at FP24 (FP24 is currently more than sufficent - however this will change in the future).
I hope both cards offer better (read faster) Shadow rendering - as both NV3X and R3X0 suffer massive performance problems when shadows are enabled esp when 4x MSAA is enabled).
And obviously both cards should be Vertex Shader and Pixel Shader 3.0 (very likely)
Well there it is peeps. Thhis could be the next GeForce and Radeon, maybe then we can enjoy games the way developers meant them to be played. Maybe thats asking too much it would just be nice to have some software that properly supported what R300 And NV30 (current video cards) can do.
