re:Prescott poor performance.

You answer is in the article.

longer pipeline (fact)

Intel had to go to 20 stage pipeline to get the speeds out of the P4. Banias is an improved P3 from Israel. A slower Banias will outperform a faster P4 because of the number of stages in the pipeline. Apparently the P4 speeds have hit a wall and more stages have been added to increase the frequency.

The Athlon has 12 stages and the P3 has 10 if I recall correctly therefore clock-for-clock the P3 and Athlon do more work for each clock than the tricked up P4. MHZ sells, so you have some consumer dudes chasing clock speeds instead of performance.

That is why the P4 is good at streaming apps and Intel doesn't want you blasting mutant aliens with a 20 stage pipeline. Now how many stages is in the new Prescott, they didn't say.
