Kinda? Apple was known to tune their ACPI tables pretty hard, it wasn't impossible for them to put a hard-limit of 70c like the other Wintel machines at the time. Instead they seemed to push the Turbo mode until you approached junction temp, which didn't seem like a smart idea for a mobile device. Especially those embarrassingly thin i9 workstations Apple tried shipping.

The behavior persists on Apple Silicon, it just gets there slower. Someone internally at Apple must have a vendetta against CPU throttling, I guess.

Heat transfer rates are higher when the difference in temperature is higher. So if the CPU temperature is below the maximum you're leaving some theoretical performance on the table. Someone at Apple has a hard on for performance data that's making them ignore real world consequences.
