Kap,

In effect, Willamette has an equivalent of a tiny ~16k L1 instruction cache, albeit a fast one. Programs with poor locality will run slow, while Willamette's single decoder is straining to fill the trace cache after trace cache faults.

Sorry to rain on the anti-Willy parade but- PIII has a 16K instruction cache, and the performance is just fine. The penalty of a trace cache miss will be no larger on Willy than an L1 miss on PIII.

ALUs transistors running at twice the clock speed generate twice as much heat as well.

The ALU runs at the same clock speed as the rest of the chip. It just completes arithmetic operations in one phase and forwards it to the next phase. Willy shouldn't draw significantly more power than Athlon at the same speed in a similar technology.

Willy will be a good performer, and run at a high clock speed. Let's not kid ourselves.
