The M1 was made on 5nm which have long been available to AMD and other competitors in volume.

Fast is relative. The Ryzen HX 370 has a TDP configurable down to 15W and at that power level it could be run fanless and would be faster than the M1, but it's still faster yet if you give it 54W and raise the clock speed.
Is that the chip AMD just released? Isn't the M1 about 4 years old?
The premise is that others can now use the same process as the M1 did to make fanless CPUs. Which they can, but they could always make fanless CPUs. The issue is that people also want them to be fast, which is not an absolute measurement fixed for all time, it's relative to competing contemporary systems with more cooling, which will always be faster.
I'm going to need source on that.

What does HX 370 score at 10w?

You're asking for a benchmark result for a CPU which just came out and has a configurable TDP that hardly anybody is going to have set to its lowest value, if they even disclose it, much less have done so in a test against the original M1. If you think a source for that even exists you can provide a link.

But the result seems pretty obvious. Even the 7nm Ryzen U-series at 15W (e.g. 7730U) was beating the 5nm M1 on multi-threaded workloads and the HX 370 is well ahead of both on single-thread performance. Single-thread workloads aren't significantly power limited, so to not be the case the Zen5 HX 370 would have to be slower than the Zen3 7730U on threaded workloads at the same TDP, which seems unlikely.

Again, would like a source on that. Please no Cinebench R23.

7730U (7nm) vs. M1 (5nm) for MT:

Faster in Passmark MT, basically tied in Geekbench MT, faster in average MT score.

HX 370 vs. M1:

Faster in everything, ST and MT. ST difference is significant, MT difference is huge. Obviously this is expected because in this comparison AMD has the process advantage, but the expected thing is indeed what happens.

Let's not use Passmark MT. Stick to the better benchmarks that are optimized for both ARM and x86. GB5 and GB6, M1 is faster in MT despite having 4 fewer cores. If you can find SPEC scores, that'd be great too.

HX 370 vs M1, what's the perf/watt for SPEC and GB5/6 and Cinebench 2024?

HX370 consumes a lot more power. Hence, there aren't any fanless laptops available for it.

4 years later, AMD's chips still can't work in a fanless laptop.
