I slightly disagree - AMD seems to go down the path of producing a CPU that fulfills all "specifications", yet just isn't a good performer.

It doesn't have 12 logical cores like 2010's gulftown already had, it has just 8 minicores.

It's not having a bigger bandwidth than Sandy Bridge, and it sure has to compete against Sandy Bridge, which it can't do.

It does have on paper however have everything. It has small L1's, it has slow caches, allowing it to clock high, it has 8 minicores, it has it has it has everything except performance.

It's a third world design.

The real question with respect to Bulldozer is of course: how many years delay did they have with it in total, everything counted?
