IIRC it's thousands per day on these systems, mainly due to high power density and low mass, even small lapses in computation (100-500ms) rapidly change the temperatures of stacked die.
So even a GPU averaging 98% utilization may have thousands of cycles per day.
Compared to a regular server blade it may be dozens or barely any at all.

How many contraction/expansion cylces do you normally see in a DC setting, generally? Is there a measure for that to baseline against?

Naive question, but could this not be fixed by a scheduler? If it's only idle 2% of the time, give it busy work for that 2%
the easier answer would be to remove the ability to idle
