Apple Silicon M1 chip in MacBook Air outperforms high-end 16-inch MacBook Pro

AMD's Zen 3 (Ryzen 5xxx series) are beating the Apple M1 in single core score: https://browser.geekbench.com/v5/cpu/singlecore

As another datapoint Ian (of Anandtech) estimated that the M1 would need to be clocked at 3.25Ghz to match Zen 3, and these systems are showing a 3.2Ghz clock: https://twitter.com/IanCutress/status/1326516048309460992

No, they aren't. All of the top results have crazy overclocking and liquid cooling. You need to look the numbers here: https://browser.geekbench.com/processor-benchmarks. Top end Zen 3 is slightly lower than M1.

Not exactly.

Up to 5050MHz is stock behavior for the 5950X and it's using standard DDR4 3200 memory.

Yet it still makes it very clear: a properly implemented ARM core can easily bury an X86 of equivalent size because of inherent advantage of not having to pay interest on 40 years of technical debt in the ISA.

ISA has very little to do with it, ARM is almost as old as x86.

ARM went through multiple iterations of its ISA. They don’t need to run 40 year old code.

X86 CPUs are not really "running" X86 ISA since Pentium Pro (1995), they are translating on-the-fly X86 instructions to microcode which is actually getting executed. ARM CPUs are also not executing ARM ISA directly and doing translation as well.

Simpler ARM ISA has advantages in very small / energy efficient CPUs since the silicon translation logic can be smaller but this advantage grows increasingly irrelevant when you are scaling to bigger, faster cores.

IMHO these days ISA implications on performance and efficiency are being overstated.
