question therefore is if there is a way to detect whether hyperthreading is supported AND ENABLED If so how exactly. c windows osx assembly.. AND ENABLED If so how exactly. c windows osx assembly hyperthreading share improve this question The way I understand the question..

I should provide an example A quad core Intel CPU's with hyperthreading enabled has 4 physical cores yet 8 logical processors hyperthreading.. enabled has 4 physical cores yet 8 logical processors hyperthreading creates 4 more logical processors . So my current function would..
