There was a card just detailed on Hot Chips that used a whole bunch of RISC-V CPUs on 2nm to run at 1.8GHz, but really low power, for compute on a CXL card that could also have SSDs for cached storage.
So, don't assume they would crank up the GHz.

I have to admit we were more in the "desktop" use case, then the 7GHz (I don't know how they will manage to keep the backend reasonably fed without severe speculation though).
