Try doing that with a CPU.
Why does the GPU have a lower clock speed? It’s because it’s locked
to the RAM speed, in a way that the CPU is not. Once you allow for
this, you realize that their performance limitations, doing like for
like, are not that different after all.
Bullshite.
GPUs have lower clock speed because this way they can operate at lower
voltage and to do more work per Joule.
High-end GPUs are power-bound beasts.
