Earlier quoted context omitted.

Snapdragon Elite X laptops are plenty decent.

Not for Linux they're not. IIRC Audio and camera don't work, and firmware is non-redistributable and so you need to mooch it off a Windows partition. On top of that the performance on Linux hasn't been great either.

Highly depends on which laptop

Now we just need a decent ARM Linux laptop.

I would wait for X2 Elite laptops at this point.

Qualcomm is already upstreaming support into Linux.

Take this with a grain of salt but since we are one the topic of games….

Anyone can recommend something viable for simple tasks? I don't need 32GB of VRAM, just a reliable machine for everyday tasks that's decent, lightweight, has a good battery. (I know I'm describing an M2 Air, but I'd like to explore alternatives.)

Lenovo Chromebook Plus 12 or Acer - Chromebook Plus Spin 514. Both have an M2 equivalent MediaTek Kompanio ARM CPU/GPU, and comes with native Debian VM built in (Crostini) that runs standard Linux desktop apps. Battery life and performance are great. You can even get it pretty loaded up with RAM to run smaller LLMs if that's your jam.

As you can tell from my past comments about Chromebooks as Linux workstations here, I'm a daily user and very happy with them.

I'n incredibly impressed by valve's commitment to playing the long game. It makes sense to have the frame by arm since the system is lighter and its clear this is just the trojan horse to get arm linux into every gamer's house. I wouldn't be surprised if we end up with an arm steamdeck 1-2 version from now when the tech is ready.

Helps that they are in dominant position and basically just need to not fuck up

Does that mean I can run windows games on my rpi? (In theory at least)

Yes (just possibly at ~2 fps)

Put a GPU on it, and you can get 30+ fps in some newer(ish) games, 60+ fps in older games.

One problem I see is that (e.g.) Qualcomm Adreno GPUs don't even run most Windows games well when executed natively under Windows, due to games only being optimized for GeForce and Radeon. I assume this problem only gets worse when trying to run DirectX games through some sort of translation layer with FEX/DXVK.

The GPU is not run through a translation layer. The GPU is not an x86-64 CPU. Only the CPU code has to be emulated. The GPU runs natively. That does not help with poorly supported GPUs of course.

Pretty sure the GPU doesn't understand DirectX, which is used for Windows games, so it must be run through a translation layer.

Not just used by, Valve is sponsoring FEX. https://news.ycombinator.com/item?id=45903610#:~:text=Valve%...

I wouldn't call this random comment reliable testimony that they are sponsoring FEX.
