Leeor Leeor Nrj, if you run one single-threaded application, it will be allocated to a single core, and activate only a single HW thread on it. If you activate another application it will usually be allocated to another core, and so on until you saturate the number of cores. Beyond that any additional thread will be scheduled to the same cores again using SMT.
Leeor apparently this was my expectation but its not what i found. Leeor I think I did the test incorrectly. Thats why all of them get busy. Note that this terminology varies, depending on who you ask. So, at least in this case, each of the 8 "cores" has two "processors", which is at odds with some other answers here. Show 1 more comment.

It probably says more than a thousand words for small creatures like ants though. Sky Be careful with ants Suraj Jain 4, 25 25 silver badges 39 39 bronze badges. Even " Intel E v2 " only has 12 cores Why do you say "hundreds of cores on the same CPU"? What limits the number of cores possible on a single CPU? Himanshu Gupta Himanshu Gupta 1 1 silver badge 1 1 bronze badge. What exactly happened in ?
Intel didn't invent the concept of simultaneous multithreading. Wikipedia says Alpha EV8 was the first major commercial implementation. But this was about the old processors There could be hundreds of cores in a single processor Eg. Do I need one?

A core can work on one task, while another core works a different task, so the more cores a CPU has, the more efficient it is. You should shoot for at least four cores in your machine if you can afford it. Some apps take better advantage of multiple threads than others.
The same applies to competing CPUs from the same time period. CPUs with higher thread counts are just better multitaskers, and that only matters when you regularly do multithreaded work.
