kpf -

Changing horses to Dothan and successors for Desktop and Server would mean giving up Hyperthreading and PNI. Both features are not really important imo, but you know it is already in all these benchmark-applications, so it will hurt.

All this takes time. Dothan would seem to be a great design for making dual core - it is designed for much lower power consumption. That would beat iHT any day!

But most important, they would close the backdoor to migrate to X86-64, which many (including myself) believe is in preparation in Prescott.

No reason they couldn't do this also. With Dothan-based desktops and servers they would still need features in the P4. Intel's market share is large enough to do both.
