WE SPOKE with some folk that that really really know how graphic semiconductor works and how far 0.13µ chips can go. Apparently you can get to 600 MHz maximum if you are skilled and lucky enough. We reported earlier that 0.13 microns R420 will work around 500MHz and I guess that NV40 might even go more then that but it seems no one can exceed 600MHz.
The next marchitecture that ATI (RV370) and Nvidia are playing with might just be 0.11µ based. It's hard to confirm whether the RV370, DX 9 PCI Express card will come at 0.11 µ but it would make sense, since this is exactly how ATI went from 0.15 µ to 0.13 µ in the mainstream market, less dangerous and less noisy, it seems
