AMD FX "Bulldozer" Review - (4) !exclusive! Excuse for 1-Threaded Perf.

[dess]

i think your mixing up statements and there were quite a few

I don't think I'm mixing up anyting.

A: using 1 thread per CU helps gaming performance, TRUE
B: using 2 threads per CU and overclocking farther can in many cases give more perf if your not on a super strong WC system, also TRUE

C: Depending on the workload, sometimes it's A, sometimes it's B that gives you the higher performance...

heres a link with details for 'A'

Thanks, but I've inserted charts here from this article already.

4/6 games got ~5% faster when using 1 thread per CU (but at the same clocks), the other 2 games were identical, aka no penalty.

Nice, but it's just a few games.
Edit: I think you're reading the chart wrongly. All games gained some (2-12% [and 40% in case of Houdini 2, although it's not of typical game load]) with 4CU/2C, compared to 2CU/4C.

the windows 8 bonus i hope is not just about making the turbo work better by ensuring threads stick to modules so the others can turn off and reduce TDP

This diagram (and the explanation here) suggests that the default mode for unrelated threads is to execute them without sharing, if possible.

since thats something we should have working now with very simple fixes rather than needed to purchase a brand new OS.

What fixes do you mean?

Regarding utilizing cores with priority on unsharing (edit: I mean automatically), and the need for Win8: I've already pointed out it should be easy to do it on Win7 by simply enabling SMT-aware scheduling (if it's true it's already supports it in case of Intel CPU's with HT). Although, in some cases you will prefer to disable it.
