The Xbox Series X has its CPU and GPU on a single chip, but the CPU runs at 3.8 GHz and the GPU runs at only 1.8 GHz. Why can’t the GPU run at 3.8 GHz too?

Question

This also applies to the PS5, why can’t the GPU run as fast as the CPU?

Answer 1

A GPU runs very specific tasks, and those tasks are “harder” than the more “general” tasks a CPU performs.

Because the GPU runs “harder” tasks, it takes longer to complete them, and the GPU has to put more effort in. This in turn results in more heat being generated (modern GPU’s run significantly hotter than CPU’s)
