Sorry; only p4-based chips can do hyperthreading, and not all p4s have it enabled. Check www.intel.com for details on the p4 family of cpus. Note that there is some level of argument whether hyperthreading is actually a gain -- it is similar to sharing a single cache among two cpus -- cutting in half the amount of cache available to each pretend processor. It is easy to envision work loads that might benefit greatly from hyperthreading. It is also possible to envision work loads that might not benefit as much as one would hope. I will be interested to see results from common operations such as kernel compiles etc... (loads I can understand; outright benchmarks are more difficult to translate into work loads I am familiar with...) -- http://sardonix.org/
