How CPU Features Affect CPU Performance, Part 4

As promised, this short article will be devoted to the analysis of probably one of the most interesting technologies used in Intel Core i7 processors -- Hyper-Threading. We were interested in a simple issue: when there are four physical cores, each split into two logical cores by HT, totalling in 8 processors per system, even an operating system may get lost in its cores. Especially as the issue of interaction between Windows Vista x64 Ultimate and eight processors hasn't been studied well enough. It's reasonable to assume that Microsoft Vista hasn't been prepared for that stuff. That's why the previous article provided some food for thought, but it didn't satisfy our curiosity about HT completely: we had to cover too much -- physical cores, logical cores, technologies.
