I am not sure I am following you. What do mean by "how much HT was enabled", and what the "old core" means? Also, it is my humble understanding that thread switching always happen no matter what, since the OS is inherently multi-threaded and run 50-100 threads anyway, time-shared. More, "...does not mean that there were no hyperthreading-related optimisations that were enabled in the Northwood core" Which optimizations ??? I think it is either "enable" or "disable" the feature. I think the matter is clear. The valid test must be as follows: 1. Take a dual-p system with ONE processor, disable MP support, install OS (which will show up as a single processor system), run benchmark; 2. Take the same system, enable MP support in BIOS, change the kernel and HAL.dll to their MP variants, run the same benchmark; 3. Compare results. ;-) Very simple. - Ali
