AMD FX "Bulldozer" Review - (4) !exclusive! Excuse for 1-Threaded Perf.
What I'm about to deal with here is comparing 2CU/4C and 4CU/4C Bulldozers.
(CU stands for Compute Unit, or equivalently 'Module')
It can be an excuse for Bulldozer's initial poor single-thread performance:
benchmark tools are just under-optimized for that kind of architecture, but not virtually a 'poor' performance if some optimization is done.
Here's the test scheme: I'm sure that everybody understand what these pics meaning for.

(real die: do they seems likely?)

(2M/4C: traditional manner for AMD)

(4M/4C: conceptual diagram)
But there's a flaw: current version of CH5F BIOS doesn's support core-by-core on/off. Am I finished then?

...Not really. Newest version of BIOS supports such function!
