I have a i7 920. It has four physical cores in addition to Hyperthreading (which the motherboard is turned on as default).
PC is used mostly for gaming as well as conversion of audio from FLAC to MP3, etc.
What I wonder about Hyperthreading is: if a game supports multiple cores, how does the allocation of cores?
In Windows (I run XP x64) you will see 8 cores in Task Manager. If a game can do to utilize two cores, how to avoid that the two cores that are not one and the same physical core?
Are best served by having to turn off Hyperthreading? Or there is a form of intelligence in either game, OS or CPU which ensures that the wires separated over physical cores?
