Claims about the Nvidia drivers on Linux being bad are largely a myth. Nvidia has long been the gold standard on Linux (for decades). The main reason for complaints is that Nvidia was slow to support xwayland acceleration (mostly due to Linux mainline making it harder for them - see dmabuf being GPL symbol exported), but that has since been fixed.

> support xwayland acceleration (mostly due to Linux mainline making it harder for them) This is not true. There were many differences with how Nvidia had been doing things in their drivers (partially due to them reusing code on all platforms) and how Mesa/Wayland was already doing things, namely with explicit/implicit sync and GBM/EGL streams, but there was no intention to make things hard for Nvidia. Mesa/Wayland e…

DMA-buf was GPL symbol exported specifically to make things harder for Nvidia. This is well known and is not the first time mainline developers have intentionally sabotaged third party driver developers. Saying otherwise is contrary to reality.

Reusing code on all platforms is a reason why the Nvidia driver has long been so good. It deduplicated effort so that they could focus on making the driver better. AMD avoided this prior to vulkan and their drivers had long been a disaster until Valve started helping on Linux. AMD tried copying the unified driver approach for the vulkan portion of their driver with AMDVLK and had some minor success, although the community driver developed by valve is better and they would be better off porting that to Windows.

I'm really intrigued to get one, but where is the 32GB version for all the LLM goodness?

There were rumors that a 32GB skew is coming.

And AMD already said there is not a 9070XT 32GB coming. Which I understand as "we're building a 32GB card with this chip, but it's not coming before christmas and will cost you a kidney".

I really would like to upgrade from my 2070 Super but I'm not getting a 16GB card now just to buy another one with 32GB later on.

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

These are gaming cards. If you think AMD is lacking here with just 16GB I can only assume you never bought NVIDIA gaming cards in the last 10 years.

You can buy used nvidia tesla p40 with 24GB from 2016 and unlike AMD, they still have CUDA support. The only thing they are missing is support for the latest data types like fp8.

NVIDIA offers one new consumer card with over 16gb.

And that one card is $2500 in practice and sold out (only launched with like 500 inventory across USA). 5090 is pure unobtanium right now unless you feel like paying scalper prices in $3k++

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.

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.

On the Nvidia side every GPU released in the last ten years competes against what AMD is doing today. People who need more VRAM go with dual 3090.

The thing is if you don’t need graphic output they are rock solid. I can understand how someone who might use them primarily in headless servers would say the drivers are great.

Graphics output is largely issue free on Nvidia too.

Contrary to what other people are saying, I've had no significant issues with nvidia drivers on Linux either, but I use X not Wayland so that may be why. Play tons of games, even brand new releases, without issues.

I have used both. The experience on both of them is at parity right now.

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…

Agreed. I've been using Linux desktops with nvidia cards for like 25 years. Every now and then I think "Well, everyone insists that Radeons work better on Linux, I'll give one a try", and every single time it turns out to be worse and I end up switching back.

Yeah the drivers aren't open source but, like, they work?

Yeah I may have been held back from switching to Wayland for a while but... honestly I did not care.

With all that said, I would really like to see AMD compete particularly in the AI space where nvidia seems to be able to charge totally wild prices that don't seem justified...
