AMD all the way. Few weeks ago I finally made a switch from Nvida for the first time. I have no problems in gaming. All games that I play run same as on windows.

Just chipping in to say I have a 3060 and I’m scared of every update breaking my drivers again - just don’t get a Nvidia, don’t do it to yourself

Short answer: AMD

Long answer: AMD used to be very bad, NVIDIA has always been the same, i.e. if you're willing to use proprietary drivers it works, but it has some hiccups. A while back AMD open source their drivers so the game turned around, nowadays they're very easy and compatible from what I've heard. I've used NVIDIA for over a decade, but my next card Winn be AMD for sure.

PS: if you're still in doubt, the latest Linux kernel purposefully broke the NVIDIA proprietary driver because NVIDIA has been copyright infringing the Linux kernel by using functions that are considered so integral to the kernel that if you have to use them you work should be considered derivative and be bounded by GPL licence.

Definitely AMD. The drivers are actually open source, much better with less bugs and there are no problems known to me. I currently have had a GTX 1070 for the last 5 years, until I've enough money for an AMD card. My setups, especially Wayland based, are riddled with bugs not present on my (Intel based) laptop - which means the only explanation is the NVidia card. The (admittedly: testing on Arch) drivers have broken two times in a year, not making the system unusable but definitely preventing gaming.
On top of that, the 4090 may be 25% better than the 7900 XTX - but it's also 50+% more expensive than the 7900 XTX, which is a pattern which can be seen for every generation and version of GPUs by Nvidia/AMD. Nvidia's equivalents to AMD's cards are generally 25-50% more expensive, with worse performance but better Raytracing and of course DLSS support - oh wait, DLSS 1 and 2 are only for RTX 20 and up, while DLSS 4 is only for 40 Series GPUs. Which means no matter how good it looks, FSR will be the only alternative for almost all players, even those using NVidia cards like me.

Something different: Intel's Arc GPUs would maybe be worth a shot. According to a PC World article, the A770 beats the 3060 even in it's own habitat - Raytracing. It's cheap and gets better with every driver update. It also seems like the Arc GPUs are compatible with Linux fine, though I'd suggest you look up the compatibility with the games you want to play.

AMD, easily. Its literally plug and play. You can even pick some second hand options for cheap that are still solid for gaming such as the vega 56/64 and the RX 5700XT (which is I use). Intel isn't bad so long as you're not playing the newest stuff, my Arc a750 is solid in games like Fallout 4 and Elden Ring. Starfield is complete mess on it. Another thing with Intel is you'll need a distro with a 6+ kernel to get the most out of it.

AMD is better on Linux most of the time. Running a AMD card day one is not hassle free.

That being said if you pick a up to date distro all 7000 and 6000 series should work fine now. They are already in the kernel and mesa for a while. You may want to update you kernel and mesa sometimes to get better performance and stability.

But in my experience nvidia is fine on Linux. (I only used older cards gtx 970 and a rtx 2060) especially when you have just one monitor or all monitors on the same refresh rate. It's not on par with windows but will work with the Nvidia drivers.

So I would say if you a simple setup Nvidia is fine and AMD is better. It all depends on the best deal you can get. If ray tracing is not that important AMD is new the best value. If you more on a budget second AMD Rx 5700 XT are pretty cheap here and there are some good deals on Nvidia 30 series cards.

As far I have read intel cards can be a pain on Linux. So I would not recommend it for now.

"Better" is relative to your own use case. If you're a casual user, who maybe play some games on Linux, and don't really care about getting those games to work with Nvidia's version of ray tracing upscaling stuff, getting an AMD card is no brainer because it's cheaper and works out of the box too, and many games are starting to support ray tracing and upscaling on AMD card as well.

But, if you absolutely need to have access to CUDA, RTX and DLSS, then you'll have to get an Nvidia card and deal with consequences of using their drivers (buggy on Wayland, etc).

well...

This sums up my feelings on Nvidia.

I am on AMD, as I had too many problems with Nvidia over the years (e.g. driver borked after upgrade and stuck on console). That said, AMD driver ain't of great quality these days either. Playing around with StableDiffusion and running out of VRAM will crash the driver and require a reboot. Some Xorg/kernel/driver versions crash frequently. One of my monitors does not work when connected over HDMI in Linux (flickering image), but works fine in Windows.

AMD is also quite a bit more challenging with AI stuff in general, as everything is using Nvidia's CUDA. The situation is however improving. On the positive side, AMD cards have more VRAM than equally priced Nvidia cards, which is far more important than raw performance in AI workloads (not having VRAM means you just can't do some things).

So not exactly smooth sailing, but AMD mostly works ok. For plain gaming via Proton I didn't have any issues.

If I were buying a card right now I'd get either the 6700XT or the 6800XT because they're both at crazy good value for the money right now, especially if you can get one used or refurbished from a reputable seller with a return policy.

AMD is generally better

I have never had issues with AMD for my graphics cards, been running team red with Linux for almost a decade now. Even switching distros no issues. But, I don’t buy new hardware, I always grab last gen, so bugs are usually worked out by the time I get my hands on it.

AMD. I’d get the rx 6800 xt

STOP recommending Intel Arc for Linux, people. Do any of you saying that even own one?

I'm mostly a newbie to Linux, I've been using it as a main gaming rig for several months and only Nobara. I hear often that AMD is hassle free, but I'm using Nvidia and honestly I've had no roadblocks. I started with a 2080ti and have since moved to a 4080, no hassles. There is a built in updater and it automatically downloads the newest driver packages. They are always a version or so behind the latest Windows set but meh. Switching on gSync was as simple as toggling VRR for my 144hz monitor.

The one thing that I needed to look up was getting ray tracing running. There was additional stuff I needed to add in Steam (copy paste from the post I found), and then RTX was up and running.

Like I say, I definitely don't know better than the people saying AMD is a smart choice, but I don't think people necessarily need to worry that their Nvidia system is a roadblock to switching to Linux.

I had a gtx1060 when I started using linux, then upgraded to 2060 then again to 2080, they all worked fine without any major problem (except that file system checking at boot sometimes and wayland). Last year I upgraded to RX6800 and man everything just works, no more filesystem checks at boot, Wayland is mu way to go now.

If I have a nvidia card now I would just use, but if I'm buying a new/used gpu it will definitely be AMD.

For gaming and desktop use, I've had a flawless experience using AMD cards and a decent time with NVIDIA. The only reason I'm with NVIDIA now is for the AI capabilities (don't bother trying to run stuff using AMD's ROCm - it's near impossible to install).

I bought a Rx 5700xt for 190€ in Germany this was 4 month's ago

Not Nvidia, they do not play well with Linux. I've had all sorts of weird problems that I've traced back to driver errors caused by Nvidia, both proprietary and open source.

There is also Intel Arc now, which does offer some relatively good value for money.

Otherwise, yeah AMD is more hassle free on Linux. Any model works, so just look at your budget.

I know which NOT to buy

Literally Intel or AMD. You may pick Intel dGPU as well.

I just built my first every dedicated Linux machine. With gaming and 3d design for printing as focus. I chose RX 6700 XT and it's been plug and play. Of course I've only been playing Starfield so far on it. I did have a bug with Steam but got that sorted.

What do you use your PC for? Just games? Or AI as well?

If it's just games, I'd go AMD. More VRAM = more better and AMD has more VRAM for the same price.

If you want to do AI on your PC as well, I'd go Nvidia. The software support from AMD is just not there yet.

I had no issues with Nvidia on pop os and Ubuntu, and rarely any issues on arch. That's the bleeding of "bleeding edge" for ya, lol. But it's a single command to roll back to a previous version of the driver, so no big deal anyway.

Definitely AMD, they give people enough data to build open source drivers and you will simply have better support and integration with those. It's not like Nvidia drivers are awful or anything but they just cause annoyances and especially with new technologies like Wayland (Display server protocol that most of Linux is about to adopt) they can be a pain. AMD GPUs work great on Linux, have far better pricing rn and they have no issues with Windows ether, even if you used Windows more I would recommend AMD rn for the pricing alone!

I can't play starfield right now because of issues with the Nvidia 535 driver causing the game to crash on starting a new game.
Downgrading to the older 525 driver lets the game play but with severe performance issues and a level of input lag and freezing that is toxic. My playtime says 4.5 hours but 4 hours of that was restarting the game with different drivers and toggling off different settings in the game for the absolute lowest performance. I'll just have to wait a month or so until the bugs are worked on and new driver versions are released.

• Valve Github Issue Tracker for Starfield
• Proton DB Reports on Starfield playability issues on Linux and steamdeck

Summary: If you are ok with playing games a month or two after release with a potential for some driver issues, Nvidia will probably be fine. I can play every older game in my steam library using Proton (which is built in to steam, you just need to turn it on in the game properties).
Otherwise it is a risk and you will always run into issues with Nvidia's proprietary drivers and new games.

I'll be getting AMD processor and GPU for my next desktop gaming computer.

I just swapped from NVidia to AMD, since Proton was not working under NVidia for Starfield at launch (and I’ve generally been unhappy using NVidia for a while).

I can finally also use things like Wayland where NVidia just doesn’t support it well enough to be a good option (e.g., weird issues with full disk encryption unlock screen, no night light support)

I know CUDA and productivity apps might push you in the other direction, but if your main priority is gaming, I suspect AMD will be nicer. My first impressions is that it plays way better with Linux and reduces headaches that shouldn’t exist but you’ll deal with under Nvidia.
