AMD's Bobcat and Bulldozer

[kl0012]

You also had separate scheduler for math and address ops in 10h,now you have the unified scheduler for both. The problem with 10h is that ALUs were underutilized(although in theory as you show it was quite capable) and BD is supposed to fix that bottleneck.

You're probably right saing that ALUs in K10 were underutilized but I have a hard time to belive that the average IPC was less then 2. Now AMD is adding many stuff to improve ALU utilization but in the same time is reducing number of ALUs. Where is the logic?
