Before going out on that limb of better performance/watt, you better see what is the current situation (09/20/05):

Manchester gets 8678 to P4 670's 31536 in 3D rendering joules. Obviously Manchester gets 3.6 times the rendering per joule than P4 670. Even the best DC P4 820D needs 22016 rendering joules. Manchester still gets 2.5 times the rendering per joule than P4 820D. The best AMD CPU is the single core A64 3800+ Venice at 8176. Thats 3.9 times more rendering per joule than P4 670 and 2.7 times that of the P4 820D.

The results are similar using 3D Mark 2005:

Intel is way behind in performance per watt (joule).
