Noticed that I ran the previously GeekBench on balanced power plan. Here are the results on Performance Power Plan - https://browser.geekbench.com/v5/cpu/16821908 https://browser.geekbench.com/v5/cpu/16821908 Summarized results - https://i.imgur.com/X5vKtFn.png https://i.imgur.com/X5vKtFn.png Overall, with the new results - AMD Ryzen 9 5900HX is 18% slower in Single Core, 4% faster in Multi Core. Not that bad ...

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.

Not that bad? Those are absolutely terrible. 4% is probably close to noise level, so essentially you are a couple of percentage points faster on multicore with TWICE the total power envelope. Think about that. And almost 1/5th slower in single core. Also, you went from "It will OBLITERATE M2" to moving the goal post "not that bad" pretty quickly. I love it.

  True. But still, pointless to me - I don't care about power efficiency, battery life or any synthetic benchmarks. I have two concerns with a laptop: 1. Can it run the latest Visual Studio at blazing fast speed? 2. Can it run Dota 2 on Full HD @ >144 fps? So far ... M2 doesn't fulfill fully neither point 1 nor point 2 :)
