I'd rather see 3D-RAM instead of DDR
First of all it's faster-
9.6 GB/s
Second-
It's dual ported whereas DDR is single
(Correct me if I am wrong)
Third-
It has some of the 2d functions of WRAM
Fourth-
It can do some 3d calculations whereas DDR can not
Obviously this can be expensive but it is only necessary for the frame buffer say 16-24 MB. The other 64-96 MB for textures can be regular SDRAM. This should balance out the cost.
