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 Someone else asked the same question.
The TL;DR seems to be that super cores are the new name for performance cores, and what they're now calling performance cores are upgraded efficiency cores.
