The M2 was a tiny upgrade over the M1 since the 5nm to 4nm step was tiny, 4nm was basically 5nm. The M3 is probably running on TSMC's 3nm which is a huge improv

The M2 was a tiny upgrade over the M1 since the 5nm to 4nm step was tiny, 4nm was basically 5nm. The M3 is probably running on TSMC's 3nm which is a huge improvement over both their 5nm and 4nm processes.
