I learned a little bit from this article: https://www.pcgamer.com/intel-explains-why-we-dont-have-10ghz-processors-by-now/

Basically, the weakest link in the execution chain determines how fast/efficient a current day CPU is based on it's clock speed. If you're a conspiracy theorist, Intel already has 50Ghz chips but doesn't want to disrupt the market :rolleyes:

"A faster frequency will speed up the initial execution. However, this will cause delays further on down the line, so nothing is really gained. According to Zhislina, the only way to raise the frequency is to shorten the longest step.

Unfortunately, there are not many ways of doing that right now. One way is to develop a more advanced technological process that reduces the physical size of the components. That makes the processor faster since the electrical impulses travel shorter distances, and also because there would be a reduction in transistor switch times.

"Simply stated, everything speeds up uniformly. All steps are shortened uniformly, including the longest one, and the frequency can be increased as a result. It sounds quite simple, but the way down the nanometer scale is very complicated. Increased frequency depends heavily on the current level of technology and advances cannot move beyond these physical limitations," Zhislina says.

Even so, there are constant efforts to achieve this very thing, and as a result we see a gradual increase in core CPU frequencies."

Correctamundo.

This is why we saw such a dramatic frequency boost with Nvidia's Maxwell/Pascal as well (losing compute > higher clocks), and why Ghz increases on CPU do not scale linearly in terms of performance.

Balance in all things :) It works for everything
