Nvidia GPU's are really your only choice. There is no framework as mature as CUDA and nvidia has been making the fastest hardware for decades. They know their stuff when it comes to architecture, so its unlikely that the hot new thing will actually be able to compete.

Also I run Linux full time, there's nothing better.

Apple side is still severely broken, you'll be fighting x86 shenanigans regularly.

Unless you use linux, where the quality of Nvidia support continues to decline.

I am running 3090 on Linux Mint and 2060 on Rocky (RHEL 9) without any issues. Both CUDA and regular desktop use.

Running KDE on both 2060 RTX laptop and 3080 RTX desktop, flawless.

Have there been issues with CUDA on Linux?

Having their cards run in servers is a big part of their business model, and Linux owns that market, so I’m surprised if their support is getting worse.

Things like poor Wayland support—sure. But then, why would somebody use this matrix-multiplication accelerator to draw graphics, right?

On my home system I've been running 2x RTX 2070's on Fedora and have had serious enough problems. It's been fairly stable for a while, but the last week or so I keep having the screen go black and not come back. I'm going to try Debian as it's supposed to have better support for nvidia cards. I've been using Fedora or Redhat for a long time, and I'd rather not switch, but these driver issues make the system unusable.

So one is for graphics and the other is for CUDA or something?

Yes, the Debian setup is going to be just for cuda and ml. It's intended for cheap and easy experiments, focusing on ml for small systems.

Hmm, I’m still confused sorry. To are you devoting both dGPUs to GPGPU stuff and using the iGPU for the desktop? Or is one dGPU doing double duty?

I wonder if it is worth trying the iGPU, if you haven’t already.

It would be a shame to distro-hop for a non-preference-based reason like this.

The screen goes dark & unrecoverable during normal use, not while using ml tools, so I just assumed it was a problem with nvidia's drivers being generally disagreeable with Fedora.

You make a a good point, I've been having one card do double-duty as hdmi output and GPGPU. I'll try the motherboard's built-in hdmi and see how that goes.

I've been really busy with other stuff for a few weeks and haven't really thought about the best way to fix this. Thanks for the suggestion!

what are you talking about?

CUDA works great on Linux. Full stop. If you’re having issues it’s because you’ve done something bizarre, like installing multiple versions of the driver. I promise you. I’ve been there and it was wholly my fault. Is it obvious or necessarily easy to fix? Nope. But that is problem with Linux and not the driver or CUDA.

Linux support is great, what are you on about? You running Nouveau drivers or something lol

Which GPUs should I consider?
