This confuses me because I thought all of the Mx series chips in the same generation ran at the same speed and has the same single-core capabilities?
The main thing that caused differential single-core CPU performance was just throttling under load for the devices that didn't have active cooling, such as the MacBook Air and iPad Pros.
Based on this reasoning, the M4, M4 Pro and M4 Max in active cooled devices, the MacBook Pro and Mac Mini, should have the same single-core performance ratings, no?
- jsheard 2y agoIt might be down to the memory latency, the base M4 uses LPDDR5X-7500 while the bigger models use LPDDR5X-8533. I think that split is new this generation, and the past gens used the same memory across the whole stack.
- bhouston 2y agoAh, interesting. I didn't catch that change.
