AMD's Bobcat and Bulldozer

[Hornet331]

Yes alus/agus have been taken out but other additions have been made like 4 issue for one. As it is i dont expect PhII to be better in single thread's but sandy bridge is a different story.

Its quite possible that sandy bridge is very good at single threads but then again you dont buy a 8c sany bridge for its single thread performance.I am thinking since power gating is on a module bases most likely so will the turbo. That means that single/dual thread single module will profit from turbo with almost the same speed.

Yes you dont buy 8c for singelcore performance, but you buy dual, and quads at consumer level.

Consumer app/game loads mostly are only partially threaded, already given some exampels.

I don't say bulldozer will have bad singel thread performance, but its a fact that for 1 thread they have less execution resources then a PII, and with the x6 we already got a x6 that clocks itself to 3,6ghz at singelthreaded loads. They(amd) have to move to a more agressive turbo mode to compensate for the lack of IPC in singelthreaded, partially threaded loads.

edit:
but thats only for the information we have now.

Hope the conference slides give more insight, so everything could change again..
