I was wodering about the new bulldozer.

If processor affinity was used to control the thread assignment so that only one thread is running on a module and not two.

Will that in some cases improve performance. Especially in gaming.

Sort of turning off amd's version of "hyperthreading".

Turning of hyperthreading on intel cpu's does in some cases increase performance. I was wondering if the same is the case with bulldozer.

Thx in advance for info. Hope someone has hardware to try this on.

Some tests have shown this does in fact increase performance, but note that this will vary application by application. Depends a lot on scaling.

Thx for quick answer. You wouldnt happen to have a link to the test ?
