I'm so confused by what's what now. Are there now 3 types of M5 cores? Is an M5 performance core an M4 performance core or an efficiency core? WTH is going on?
@paul Efficiency Cores got so good they got Performance Cores and therefore the better performance Cores are now Super Cores? I have no idea.
M5 Pro and M5 Max are surprisingly big departures from older Apple Silicon

Apple is using more chiplets and three types of CPU cores to make the M5 family.
