6 reasons CPU cores don't matter anymore
The number of CPU cores really doesn't matter in the larger scheme of things.

The floodgates were officially open when Intel and AMD brought dual-core and quad-core CPUs to the mainstream in the early 2000s. Core count became one of the biggest metrics of CPU performance and has remained significant to this day. However, with advances in CPU architecture and denser process nodes, the role of core count isn't as critical anymore.
