The increase over M3 is almost entirely due to increase in clock speed, and the effect of Geekbench 6.3 supporting SME for a small subset of tests, which leads to those tests running ~2x faster on M4. The actual IPC increase on general purpose code is small, around 3%. Apparently Apple has added SME to the M4 cores, which is cool, but makes comparison to previous cores a bit suspect unless your specific application can actually benefit from SME.

- aurareturn 2y agoThere are only two possibilities: 1. Apple changed the design of its cores to achieve higher clock speeds without raising power. In other words, they deliberately decided to alter the design to get these results. 2. N3E is going to be a legendary TSMC node. Could be a little bit of both.
- fh9302 2y agoIf your compare the Geekbench 5 results there is an approximately 8% IPC improvement. Geekbench 5 does not use SME.
