Thread: Where is Multithread on Phenom II?

Guys i am very happy with this link http://www.anandtech.com/cpuchipsets...oc.aspx?i=3674 yes Bulldozer has CMT instead of SMT. Note from Anand “A major focus is going to be improving on one of AMD’s biggest weaknesses today: heavily threaded performance . Intel addresses it with Hyper Threading, AMD is throwing a bit more hardware at the problem. The dual integer clusters you may have heard of are the route AMD is...

Wasn't that proven to be a hoax when Phenom 1 came out? Is this said hoax rekindled or is it something new?

The L3 cache sorta dose this already when I run AOD with one core for stability test the other 3 somehow get at least 25-50% load, even though it set for one core. this could just be vista 64 bit though, I'll post a screen shot in a few minutes.

What if there are no cores, only threaded dreams? What then?

Yea sure, true quad vs dual with HT, is better.. but i7 (or i9 in close future), has HT.. which makes them quite effective (at least for crunching). He tought about disguising quad core as dual core and sell it as "dual-core with HT". Which is simply stupid. i7 with HT is regular quad wich is able to use unused processor time for additional thread, hence CPU is more effectively used than without that.. but its still...
