AMD cuts to the core with 'Bulldozer' Opterons

[-Boris-]

Boris,using Athlon II for future comparison isn't the best choice due to lack of L3.IMO any other 45nm core(Penryn,Deneb,Thuban,Lynnfield) with solid amount of cache will do great for future games.Bulldozer is supposed to bring another level of shared cache(L2,shared by core pairs) and with more cache and more much improved cores(8 for desktop) I bet it will do great in games.

But they perform the same when bottlenecked?
So L3 matters, but performance don't? A phenom II 910 and a Core i7 980X will perform the same in games 2014? I have a feeling that the benchmarks made today which aren't bottlenecked will give a good clue on the 980X scenario.

BD scaling(the often quoted 80% figure) just means that instead of 8x perfect scaling you can look at the 4x1.8=7.2x for applications that can scale to 8 threads perfectly(like Linpack).This is around 11% penalty,in other words pretty good scaling if application is able to use the cores efficiently.

This is all wrong, there are no numbers of scaling on multiple modules. The only number we have is within a module, between one and two cores.
And 1.8x is 90% performance per core.

How can you get 80% scaling to 11% penalty? The numbers are 90% and 10%.
