RX 7900 (RDNA 3 flagships) are officially supported. I think the 6900 (RDNA 2) was supported at one point as well, and in both cases other cards with the same architecture could usually be made to work as well.

Do you assume that it working means official support? I had been under the impression that RDNA had unofficial ROCm support.

I've been using my 6750XT with rocm ever since I picked it up ~2 years ago. Idk if it's "officially" supported but it's works with SD and LLMs just by setting an environment variable.

They are not a myth, those cards frequently have issues with newer hardware and a whole handful of issues wayland itself such as screen tearing.

I am running Wayland on a 3090 Ti and there are zero tearing issues in KDE plasma 6.2. I do not know what you mean by “issues with newer hardware”. It has always worked just as well on Linux as it worked on Windows as far as I know.

Graphics output is largely issue free on Nvidia too.

this has never been the case for me, and evidently for the vast majority of others as well.

Those who have had or perceived issues tend to be the loudest.

I have had a good experience with Nvidia and when there is an issue, I report it and Nvidia fixes it within months. The only time I have seen a better turn around was Intel graphics, where they fixed things within 24 hours after I pointed out a bug in their kernel driver. AMD graphics on the other hand seems unresponsive to community reports or outright refuses to handle issues.

For example, they refused to implement VK_EXT_fragment_shader_interlock in AMDVLK despite implementing the equivalent for D3D12 on Windows:

https://github.com/GPUOpen-Drivers/AMDVLK/issues/108

The damage in that case is limited to Windows, as the community driver for Linux implemented it, but it made cross platform support in emulators more difficult. If it were not for Valve working on the community driver, the Linux experience on AMD graphics would be no where near how good it is on Nvidia graphics.

Is modern Radeon support on Linux still great? I've heard that NV Geforce on Linux was kinda bad since ever, but it has massively improved over the past 3-4 years. Is Radeon still the way to go for Linux? EDIT: My usecase is a Linux gaming PC. I was fortunate enough to score an RX 6800 during the pandemic, but moved from Windows 10 to Linux a month ago. Everything seems solid, but I'm looking to upgrade the whole PC…

I helped a friend install Linux last year; they had an NVIDIA card, aaaand they had problems. Both in X and Wayland. I'm was on a 6000 series at the time and it worked great, as you know. I am on a 7000 series now, and it's as smooth as ice. AMD is the way to go for Linux. There's that new NVIDIA driver cooking, but I'm not sure what the status is on it. BTW, even Ryzen 3 is a substantial upgrade over 1. Any X3D proc…

The status is that NVIDIA latest mostly works on Wayland now, but if you are on Debian the timer just started for it to not suck by default.

No ROCm at launch? After they delayed it for months? What a joke. That's like not having CUDA available at launch. https://www.phoronix.com/news/AMD-ROCm-RX-9070-Launch-Day

This card is marketed to consumers, not AI developers. Most people who will buy these cards don't even know what ROCm is.

Edit: it just doesn't matter for launch day. It'll likely be supported eventually.

I resorted to scripts from smxi.org for installing the Nvidia drivers on Debian and my GTX 770, but AMD RX 7800 XT is just fine with some firmware enabled.

Ubuntu seems to be even better. I turned my system into a Frankendebian for a day to try out ROCm, the AMD install scripts work out of the box on newer Ubuntus.

16GB? In 2025 that seems very small for anything other than gaming.

These cards are $550-$600 16GB is great for what these are: Gaming cards. Even on the nVidia side you have to spend $2000 (likely more) to get more RAM than that. You could buy 3 of these for the price of a single nVidia 5090.

I suppose it's dissapointing that the 6800xt launched over 4 years ago at $649 with 16gb as welll. Inflation can partly explain this, buts still - we had been used to progress across the board each generation previously, at least with AMD.

On Linux, there is official support for a few Navi 21 (gfx1030), Navi 31 (gfx1100) and Navi 32 (gfx1101) cards [1]. As you mention, in practice, there's also quite a few cards that work but are not officially supported.

It does seem like there is room for an $700-800 9070AI with 32 gb vram.

There's room but neither GPU vendor is willing to sell 32gb at that price

I get their point, but at the end of the day it's politics and marketing having it their own way.

With a 32GB card well below 1000$ it would sell like candies for anybody doing anything AI-related that's not training (you can easily run inference and fine tuning on such a card).

But it would massively eat in their data center sales which is what executives and investors want to see.

It's a tragedy because such a card would get a lot of love and support from amateurs to make it work great in the ML/AI context and thus improve their data center offerings long term.

So this is gonna end up in the same fashion AMD turns: it will disappoint or be ignored by most gamers cuz it has less brand power and no DLSS, and AMD will still disappoint at the data center level.
