Sure, but the M1 generally has a high-quality Apple screen (this laptop from HP advertises only “FHD” so - presumably 16:9 1080p and not Retina-quality 16:10…) and the Ryzen, though much less constrained than Intel still likely has a “boost clock speed” and power throttles itself when disconnected from power or due to heat. By comparison, it’s hard to call the M1 the fastest computer I’ve used - desktops are plenty fast - but it’s certainly the most consistently performing laptop chip I’ve ever used, and is entirely quiet and cool to the touch at all times. It’s hard to compare the values of macOS and Linux because they are very different, but it’s still easy to say that an M1 has excellent uses on macOS and everyone interested in non-Apple machines is (to some degree) waiting to see what Qualcomm or Nvidia can come up with in the ARM chipset space for non-macOS laptops… I think ChromeOS laptops prove that iPad-like performance is possible, but so far only the Apple M1 has shown that traditional x64-like performance is possible on laptop/desktop from ARM chips.

> but so far only the Apple M1 has shown that traditional x64-like performance is possible on laptop/desktop from ARM chips FWIW, ThunderX will sell you a 96 core arm64 desktop that definitely offers x64-like performance. And Ampere will sell you a 256 core arm64 2U server node that matches the performance of the fastest AMD Epyc Milan CPUs. AFAIK there is no desktop case that supports the motherboard of the latter, but there is no reason why you couldn't make one. These things are a bit niche, since the main benefit of arm64 is the reduced power demand at a given performance level, which desktop/workstation users seldom care much about. In the data center though they are killing it, I believe Azure is using the Ampere Altra stuff for their Graviton2-competitor.

> Sure, but the M1 generally has a high-quality Apple screen (this laptop from HP advertises only “FHD” so - presumably 16:9 1080p and not Retina-quality 16:10…) This looks like their current generation Pro/EliteBook lines. I have one of the higher end ones (EB 845) and oh boy does the screen suck. Not just compared to my 9 yo MBP. But even on its own. Very low angles, washed out colors. It's only advertised as 72% NTSC IIRC. Cheaper models have 6-bit panels on which you can see the dithering in the window shadows. It's laughably bad. And it cost more than similarly-specced MacBook Air. Other than that it's a usable PC, plenty fast for my needs, and the RAM and SSD are easily upgradeable. Battery life is OK-ish (I get around 6 hours). Also, everything works under Linux and is even less of a hassle to get going than on Windows (you need an external mouse to install it).
