Does the core speed of an M1 core change at all? I thought they used the low/high power cores at fixed-limit clock speeds.

It sounds crazy to consider, but maybe they’d rather not try to speed up the individual cores in M1 Max, so that they can keep their overhead competitively low. That certainly would simplify manufacturing and QA; removing an entire vector (clock speed) from the binning process makes pipelines and platforms easier to maintain.
