> Apple's Arm cores now have significantly higher performance per clock cycle than any traditional x86 PC processor.
I am not an expert but this claim sounds way to high.
- tenebrisalietum 3y agothe claim probably does not include server processors, if that may make a difference.
- dagmx 3y agoServer cores don’t tend to have more perf per clock on a single core. They scale by having multiple cores. So I’m not sure this matters because the statement in question is per core.
- The_Colonel 3y agoARM is also a bit of cargo cult. Apple CPUs are efficient and performant, other ARM CPUs not so much. If it's really the ISA or other "secret" Apple sauce, which makes all the difference, is not completely clear.
- hypercube33 3y agoAlso some things to consider is that apple dropped the majority of legacy software support and runs native arm64 code for a majority of apps. also somewhere I saw that amd64 is better performance per watt than m2 or m3
- minimaul 3y agoI have a 35W AMD 5750GE (zen 3, 8c16t), along with M1, M1 Max and M2 Pro devices - the AMD processor and M1/M2 chips trade blows depending on workload. It’s absolutely possible to get x86_64 to the same power/performance envelope as apple’s M series chips :)

- CardenB 3y agoYou have to admit, “secret Apple sauce” does sound rather tasty.
- GeekyBear 3y agoAt the time of the M1 launch, Apple's chips preformed more instructions per clock cycle than Intel or AMD chips. > What really defines Apple’s Firestorm CPU core from other designs in the industry is just the sheer width of the microarchitecture. Featuring an 8-wide decode block, Apple’s Firestorm is by far the current widest commercialized design in the industry. https://www.anandtech.com/show/16226/apple-silicon-m1-a14-deep-dive/2 https://www.anandtech.com/show/16226/apple-silicon-m1-a14-de... They also ran the clocks slower for power efficiency.
- gruez 3y agoIt sounds way too high because the claim itself is weird. It doesn't claim that arm cores are faster than x86 cores outright, but rather they're faster if you normalize by clock cycle. Also depending on the benchmark chosen, you get very different results. If you combine the two factors the claim is probably true. https://www.cpu-monkey.com/en/compare_cpu-apple_m3_max_16_cpu_40_gpu-vs-intel_core_i9_13900ks https://www.cpu-monkey.com/en/compare_cpu-apple_m3_max_16_cp... https://www.cpu-monkey.com/en/compare_cpu-apple_m3_max_16_cpu_40_gpu-vs-amd_ryzen_9_7950x https://www.cpu-monkey.com/en/compare_cpu-apple_m3_max_16_cp...
