The Extreme Edition processor has hyperthreading and a faster bus... The non-extreme processors don't have HT for MONEY, not for heat.

There's hardware sites which benchmark the processors for energy consumption and find that turning on hypthreading increases power consumption (which increases heat).

But anyways, does it really matter why hyperthreading isn't there?

Can you post a link?

I'm sure that it does matter why HT isn't there... After all, if you are claiming heat issues with HT, it would be useful for individuals reading this thread to take that into account as well... If it doesn't matter I'm not sure why it was mentioned.

Hey I've been reading dual core comparisons till my eyes fall out. I found this link to be very helpful.

I rearanged my wish list and I think I've talked myself out of the Intel option. Sigh. I should just order this thing and get it over with. :}

I was talking more specifically about Hyperthreading in conjunction with heat.
