The single core performance looks really fast. Chip | Geekbench Score (Process) ---- | ------------------------ M1 | 2,419 (5nm) M2 | 2,658 (5nm) M3 | 3,076 (3nm) M4* | 3,810 (3nm) In my experience, single-core CPU is the best all-around indicator of how "fast" a machine feels. I feel like Apple kind of buried this in their press release. M4 benchmark source: https://browser.geekbench.com/v6/cpu/8171874
The press release describes the single core performance as the fastest ever made, full stop:
"The M4 family features phenomenal single-threaded CPU performance with the world’s fastest CPU core"
The same statement is made repeatedly across most the new M4 line up marketing materials. I think thats enough to get the point across that its a pretty quick machine.
