That's not such a good result when you're talking about a chip with a 54w TDP (even more peak) vs a ~20w peak TDP for the M2. 4% faster for 2.5x more power isn't a win. The fact that 95% of users care more about that 18% single-threaded performance makes this even worse.

The TDP of the 5900HX is 45W. Don't forget we are comparing last-gen AMD vs current gen M2. M2 on Mac makes 1884/8717, but on Paralles -> 1681/7260. So, the penalty is 11% on single, 17% on multi because of running on Windows via Paralles. APPLE M1 average Single Core is 1706, average multi is 7421 on MAC. If we apply the above penalty becomes -> 1706/7421 -> 1522/6180. AMD 5900HX average Single Core is 1413, average multi is 7656. So, AMD - 1413/7656 | Apple M1 - 1522/6180 -> Amd is 8% slower in single, 19% faster in multi.

  > The TDP of the 5900HX is 45W. The TDP according to AMD's website is "45+W" which they clarify to be a cTDP up to 54w TDP. https://www.amd.com/en/products/apu/amd-ryzen-9-5900hx https://www.amd.com/en/products/apu/amd-ryzen-9-5900hx
