No. AMD Ryzen™ 7 PRO 5850U can boost upto 4.4Ghz, likely it would be consuming upwards of 50W for that short duration.

An easy way to verify it, is to measure the benchmark delta when on battery and when connected to an external power source. (M1 benchmarks remains almost the same)

Intel i7 9750H for example has a P2 of above 80W and only then can it break the 4Ghz barrier. Even though the processor is technically rated only 45W. At 45W it can just maintain the base clock i.e. 2.6Ghz on all cores.

M1 is much more efficient than any x86 chip on the market right now.

The M1 is hitting 4gHz across only 4 of it's cores, whereas the 9750 is driving 6 (and 12 threads on top of that). Furthermore, the M1 will have no problem hitting ~20w during peak load, so frankly the math checks out to me. The comparison definitely starts to deteriorate once you consider that the M1 is ~3x as transistor-dense as the Intel chip, and part of me actually wonders why they didn't get more power out of a chip that only needs to worry about a handful of instructions and doesn't know about hyper-threading.

Pretty sure M1 does not hit that frequency on any of its cores…

[smoldesu]

I was under the impression that the performance cores had hit 4.1gHz before, is that incorrect?

Max frequency is 3.2GHz and you can max pretty much indefinitely on the pro with a fan or the air with the heatsink mod.
