Why are there no #8bit #CPU with #GHz #clock-rates?
Here's some answers

> Most 8-bit AVR chips have a maximum clock of 20MHz. For many applications that's enough, but it made me wonder: why do even modern 8-bit CPUs lag so far behind 32-bit CPUs in terms of clock rate?

Not sure on this, but would a higher clock speed require more work from the CPU and more heat given off?
@zleap as far as I remember the heat dissipation goes with the square of frequency.
This is addressed in the linked discussion; I found convincing the "because there's no market for them" reason
