Intel Core i5-11400 Runs Without a Cooler Under Thermal Camera

[Wirko]

For some time I thought that all of the cores in a multi threaded CPU were accessible at the same time.

After being a PC Pro for 15yrs it was studying data science when I really gained a good understanding of how a CPU works and how the multiple cores are accessed.

This is what gives GPU's the advantage with certain tasks as the same instructions can be run in parallel (as we all know), where as a CPU only accesses one core at a time... all be it very quickly.

It still has to use the cores individually. It was fascinating seeing each of the cores being used and the speed each core was accessed after the one before. Brilliant video!!!

Hmm ... how do you mean that?

Your 5950X is able to run up to 16 independent threads of program code at the same time, or up to 32 with lower performance.

What Fritz did was starting Prime95, then telling Windows to allow it to run only on a specific core. The default is all six cores - however, a process with less than six threads could never use all of them in parallel.
