Bulldozer has taped out
The new cores were said to begin sampling to OEMs in 2010. When pressed on the timing of tapeouts, one AMD spokesperson said that the fabs were 'running product now'. That means the chips have taped out and the fun is about to begin.

效能增益，FPU改善比較多





從架構圖看來每個核心有4個整數管線那IPC至少為4，如果兩個核心可以共同執行一個線程(兩個核心當一個用)那IPC說不定可以衝到8(傳說中的逆向超線程!?)
