"M2 takes the industry-leading performance per watt of M1 even further with an 18 percent faster CPU, a 35 percent more powerful GPU, and a 40 percent faster Neural Engine"
18% faster at the same performance per watt is a nice increase. Interesting to see if this will ever make it to their desktop computers.
- paulmd 4y ago> 18% faster at the same performance per watt is a nice increase. 18% faster at the same wattage, which means 18% higher perf/watt.
- skavi 4y agoHave they confirmed anything about power?
- kllrnohj 4y agoSince they never made any specific power claims of the M1, why would you expect them to make any such statements about the M2? You'll have to wait for 3rd party reviews and analysis for that.

- skavi 4y agoAh, completely missed that slide. Thanks!
- smoldesu 4y agoGPU wattage seems to be increasing, but that appears to be linearly correlated with the number of cores they're adding. Still a bit of an "Intel Moment" all things considered, but not as bad as it could have been.
- ntoskrnl 4y agoThe 18% is for multithreaded workloads. Have they said anything about single core perf yet?
- joakleaf 4y agoNo they didn't reveal single core performance. It is commonly assumed that M1 shares high performance Firestorm cores with A14. It looks like Geekbench scores for A15 over A14 is about 18% in multithreaded, and 10% in single thread. It is also very likely that the M2 uses the same Avalanche cores as in A15. So I would suspect that this translates to a 10% increase in single threaded performance between M2 and M1 as well. Incidentally, A15 runs at around 3.2 Ghz vs 3 Ghz for A14. So the majority of the speed-up between A14 and A15 comes directly from increasing clock frequency. M1 runs at 3.2 Ghz.
- sliken 4y agoI didn't see anything, but inferring from what I can find it's mostly improvements the slow cores (icestorm -> blizzard) improvements. The fast cores (firestorm to avalanch) seems like a very small difference.
