Would Tukwilla beat a Clovertown with IMC/CSI ? I seriously doubt it.
The 65 nm dual core FSB based Woodcrest beats the 90 nm dual core FSB based Montvale on many HPC apps and loses to it in many other HPC apps.
That is a comparison between an out of the park home run of an x86 design with a full process shrink advantage to an IPF design which fell substantially short of target due to project managements issues.
If this was an x86 vs x86 comparison it wouldn't have even been close.
