Phenom was bad in branch prediction, so AMD improved it far beyond intel's best, just watch the die space used by it on the only "litle bobcat". It's just impressive. Alu Pipes seem to have been change from 3ALU/AGU that can do 1.5 of each per cyle to 2AGU + 2ALU that can do 2 per cylce. So more IPC.

About L1D it's not very clear, we need know if it's inclusive or not. So it can be incredible faster, or simply as good as old Phenom II, latency is said to be masked.

L2 latency is 17cycles, so it's not bad. and seem to be 1MB and shared between 2 Alu cores, so that mean less data will go L3 to change of core.

Pipe is longer, but aimed for ramping up clocks, and prediction is far better to hide the bad effect of the long pipe.

It's gonna be the "core 2" effect i think.
