Remember that ATI licensed Fast14 Technology from Intrinsity.

Well Intrinisity has update their site with 90nm and 65nm performance projections.
Looks like the math engine is fast and probably more important is that consumes far less power. This might mean that when ATI goes 90nm they may have lots of extra transistors to play with without wicked overheating.

Higher Performance
CMOS process improvements no longer yield dramatic performance increases. Fast14 Technology has achieved multi-GHz performance in processes ranging from 180nm to 130nm. Performance of 400 MHz to 4 GHz is achievable with Fast14 Technology at 90nm and 65nm without requiring exotic processing techniques.
