Sadly no M2 comparisons (I know they are a Linux site)

If you plug some numbers in, In terms of Pref / Watt M2 is still ahead. But 7840U has closed the gap.

  Does this mean that the Perf/Watt of the M2 Max 12 Core is almost half that of the Ryzen 9 7945HX? I think it's impressive to not only double the performance, and still keep roughly the same power rating.

Blame Apple - Linux is still a 2nd grade beta OS as the team trying to port Linux to Apple is still working on reverse-engineering many of the parts of M1 / M2 SoC. Until Apple actually provides documentation to system developers, we'd be fools to buy and trust the M1+ platform.

  I wouldn't be that strict. It's not like many PC laptop manufacturers provide drivers or documentation. Buying a laptop like Acer or other known brand, you're still relying on a few reverse engineered devices.

    Only a few though. Support for the CPU, chipset components and GPU are contributed by the component vendors themselves. Other components use standard interfaces, like AHCI, XHCI, NVMe, HD audio, ... Not much remains up to the brands like Acer which didn't really provide any components themselves, only put them together. Meanwhile on the M1, even keyboard support was implemented fairly late and is not mainline yet.

The initial AMD announcement included some comparisons, for example "AMD also included battery life benchmarks comparing the Ryzen 7 Pro 7840U against two Core i7 models and the Apple M2 Pro, with the former both having a battery capacity of 54 Wh, while the latter had a 69.6 Wh battery. Meanwhile, the Ryzen 7 Pro 7840U system was equipped with a 51.3 Wh battery yet managed to deliver longer battery life than all three competing laptops, with the highest delta being a 70% advantage over the Core i7-1370P" https://www.tomshardware.com/news/amd-intros-ryzen-7000-pro-mobile-and-desktop-chips-ai-comes-to-pro-series https://www.tomshardware.com/news/amd-intros-ryzen-7000-pro-...

  "AMD says AMD is the best." Wow, I'm so surprised. I also think I am the best(/s). I still find this compute per watt thing such a silly thing for any company to care about. Until Apple did it, it was not on anyone's minds. Once Apple did it, they dumped a bunch of money into marketing a metric that no one cared about; and now people pretend to care about it. Not to mention this obsession with CPU that I just cannot grasp. Not sure what industries this is the bottleneck.

    The sheer audacity to claim no one cared about perf/watt before Apple. More like you did not know what it is before you consumed Apple marketing.

        VR (sorry, "spatial computing" now, Apple doesn't do anything that can be dismissed as a gaming peripheral now..) is another recent example.
