https://youtu.be/QS4fzElm8zk https://youtu.be/QS4fzElm8zk Purpose built hardware can do many operations in a single or fewer clocks. For example reading an input, doing some math to it, and outputting it. A modern microcontroller can do some of that pretty fast, but change over to something like a PC and you're actually fighting a lot of delays in processing. For example you cant just thread out the various hardware components and emulate them efficiently. The OS is going to schedule when those threads execute. Therefore you get locked into one core and are dependent on single clock speed. Even then you're fighting inefficiencies in emulating real hardware.
