Today, i was curious with the performance difference w/wo HT. And guess what, with HT disabled , on load Temps dropped by 2C and PWM dropped 7C. Tests were run with foldings, yeah, not the most stresstful program out there.
Anyways, no big deal, juz to point out tat, the CPU and PWM temps were affected by HT, a reduction of 2C and 7C respectively. [ as of my setup]

HT is a 'visual' cpu , it fools the OS thinking there are '2' CPUs.
DUal core on the other hand is different, there are two actual physical core exist.

QUOTE(charge-n-go @ Mar 28 2006, 01:40 AM) disabled HT means CPU is less occupied with data to process. Hence less work is done (less W). Tat's y u see 2C drop in yr CPU. W = I x V, where I is the current and V is the voltage. for a fixed vcore, if W drops, current sure drop ma. PWM is in charge of supplying current into CPU. If less current, PWM oso has less load, so temperature drop oso lor. mmm, I've got a question here [i'm no comp engineering ,what so ever  ]. How does this differ as a disabled HT would be less occupied with data to process, but at the same time, it is now 99-100% dedicated to a single process. Isn't it the load wattage drawn should be equalled? Btw it is P=VI [general term ] @KilJim, ooppss yeah should be 'virtual' guess the exam stress has taken its toll.

thanks for the head ups charge-n-go. Finally it made sense for the temp increase
