AMD's Bobcat and Bulldozer

[Florinmocanu]

People do not get one thing.


the comparison of the BD module having 180% performance of 2 cores (which would have 200%) is not done in regards to a 10H core. So... a BD module (with two cores) is not 180% of 2 thuban cores. That is plain dumb to believe.

The 180% is vs 2 proper BD cores. So, instead of having 2 full Bulldozer cores for 200% perf, they chose a module aproach, giving 180% but at 50-60% the size of 2 full cores. Thus, you pack more cores into the same die.

This is exact the thing people like terrace hang on, that BD cores loose 5-10% compared to Thuban. That is just naive to believe. They loose 5-10% in fully threaded applications vs 2 theoretical BD full cores.
