BD Gaming Affinity

[sm625]

Does anyone know of a review that benchmarks games with the 8150 manually configured to use only one thread per FPU? (ie, core 0 active, core 1 disabled, core 2 active, core 3 disabled). Either done by disabling cores in the bios, or by simply setting the cpu affinity of all the relevant processes from within windows.

Here is what i think your saying.

Thanks. I found this for anyone who is interested:

About 5% faster when you disable odd numbered cores. Couple that with hopefully a 10% increase in overclocking headroom and we might be able to eek out 15% more fps.

Or just, you know, buy Sandy Bridge and get 20% extra FPS without doing anything. Up to you!

Some pretty solid improvements, more than I was expecting. With a module aware scheduler this architecture should work quite a bit better. Just a shame we have to wait for Win 8 for that. Can MS not release a hotfix or something for Win 7 users?

Not enough improvement The problem is that windows is already juggling so many processes that the gains wouldn't be nearly as dramatic as this bios disabling works, because even with a smarter scheduler, just sharing the module will reduce performance.

If AMD couldn't do it with it's research $$$ and engineers...I have doubts bunch of nerdy geeks can.

May not be quite as dramatic, but I'm optimistic, I bet it will help quite a bit in situations using four or less threads. AMD had that slide that showed anywhere from 2-10% increase in gaming performance between Win 7 and Win 8 developer preview. Left 4 Dead 2 (the most CPU limited game among those listed?) saw a 10% improvement. Looks promising IMO. Like I said just too bad enthusiasts may have to wait until Win 8, seems like this is something important enough that MS should release a hotfix for Win 7 users.
