4 modules, 4 threads occupying cores 0,2,4,6
2 modules, 4 threads occupying cores 0,1,2,3
4 modules, 4 threads occupying cores 0,1,2,3,4,5,6,7
- each test repeated 3x to check score consistency
- Windows Scheduler still not properly prioritizing cores (priority should be in the following order: 0,2,4,6, then 1,3,5,7) sometimes. (With second monitor, can watch while gaming. Sometimes 0,2,4,6 are the loaded cores. Haven't paid attention to which games but mainly UT3)
- Cinebench r15 overrides core affinity settings affecting benchmark performance. To get around this (if you'd like to repeat the test), have the 'affinity' window open with the settings you want, and click 'OK' after you start the bench run. Verify the proper cores are being loaded in Task Manager or SpeedFan. 0,2,4,6 should be pegged at 100% and 1,3,5,7 almost completely inactive.
- 16.4% [!!!] threading performance improvement when scheduling four threads to 0,2,4,6 instead of 0,1,2,3
