There it states this: "Two times 4 Bulldozer modules (2 x 8 "cores" or 16 cores) are about 60 to 80% faster than the twelve core Opteron 6100 CPU in SPECInt_rate". Lets presume that's for two CPUs clocked at the same frequency to make it easier. This would mean that a single BD module will be about 20% to 35% faster than a dual core K10.5 based CPU in integer performance. In a later article by AnandTech, Anand simply states this:
I actually wouldn't be surprised if a single BD module is at least about 10-20% faster than a dual core K10.5 CPU in general performance. Remember though, that single BD module will be about the same size as a Sandy Bridge core, maybe a bit smaller than that. Quite an achievement.

That's all still a bit speculation though. We'll just have to reserve judgement until it's launched.

how does Anandtech got such information???
