Because this was reported last time with the M2 vs M1. The major performance improvements came from increased clocks, at the expense of some core stability.

These new cpus can bounce tracks faster, but are apparently worse at real-time processing. Most DAWs can only process individual tracks on a single thread.

If you’re monitoring while using heavy plugins then you may be more prone to dropouts on the newer chips.

The different # of P and E cores plays more into the multithreaded performance

Imagine 2 runners racing. One can trip and fall, get up and still win. Faster but less stable. For real time signal processing you have to maintain a minimum clock or dropouts and artifacts will occur.

It means the clock frequency varies more than M1

My guess is this has to do with core stability. Dropouts occur more easily on the newer chips because the cores behave more erratically, even though they’re faster overall.
