A ninth metal layer and 400k more transistors seem to be the major change. I'm willing to bet that a lot more rerouting of speed paths were involved, too...

Nine metal layers has GOT to be cutting into the profit margins. Each additional layer involves additional costs, so jumping from six at 0.18 micron to nine at 0.13 has got to hurt somewhere...

Wanna_bmw - I remember your post from yesterday about Ali Chin predicting a performance drop when enabling hyperthreading. I ran across this infoworld article which seems to disagree:

"The performance advantages of hyperthreading are undeniable. Our tests of a hyperthreading-enabled Intel Xeon DP server showed, on average, a 45.71 percent increase in SQL transaction performance and a 31.13 percent increase in three-tier Web application performance, versus the same system with hyperthreading disabled[a P4]."

Our AMDolt friends don't want to know what Hyperthreading will mean for Prescott.
