Does the M2 MacBook Air throttle worse than the M1 for 4K ProRes video editing?

Yes, the M2 MacBook Air thermal throttles more aggressively than the M1 during sustained 4K ProRes video editing, and in long exports the M1 can actually hold a higher average performance. The M2’s bigger, faster chip in the same fanless chassis causes it to hit 108°C quickly and drop clocks to 1.8–2.0 GHz, while the M1 stays around 2.4–2.6 GHz.
