I just got hold of an AMD RX7800 XT to replace my current Nvidia RTX3080.
I’m likely overthinking this but from what I understand I should just be able to swap the cards then uninstall the Nvidia drivers correct?
I’m running EndeavourOS which I installed with the option to include the Nvidia drivers by default so dunno if that changes anything? I’ve been daily driving Linux for exactly a year as of this month but I still kinda feel like a newbie sometimes lmao. Thanks in advance!
(Update) I got my AMD card installed and loaded up Wayland with no issues, only thing I had to install was the AMD Vulkan drivers for Steam.
I’ve never done the process myself, but I would probably uninstall the nvidia drivers while the system is still running, install whatever amd packages you need I know there are some vulkan packages that people need that aren’t installed by default, and then power off and swap the cards.
I’m not familiar with these vulkan packages, what should I look for?
I don’t have an AMD card, so I don’t know, but I recall reading on the endeavourOS forums of people solving their AMD gaming issues by installing the proper vulkan packages. That is to say. You should head to the endeavourOS forums and peruse around there. You will probably find that information very quickly there.
Thanks! I’ve not been having many problems, but if it’s causing a performance loss it would be good to take care of it, I’ll check that out
You just got me to remember something about a Vulkan package when I first installed Steam so gonna find the AMD package for that. Thanks!
You shouldn’t need to install anything for the amd gpu
Most distros have a vk package that steam depends on that varies based on hardware, there is a system different package for amd than Nvidia or Intel.
Oh right. Do you have a distro specific example of this?
Here’s what you need for Arch, for more context: https://wiki.archlinux.org/title/AMDGPU
Isn’t this the kernel driver included by default?
The wiki tells you what you need on arch, and what you need it for. Those packages also don’t seem to have kernel-specific or dkms versions, so seems like they’re not kernel modules.
Mind you, the setup is clearly not monolithic, with different components for different purposes, including alternative options. On top of that, each distro will make different choices - Arch provides the components as packages and puts the responsibility of installing the right ones on you. Some features might be built into kernel drivers, like working video output, but Vulkan support clearly wants a dedicated driver.
Even if you install the drivers while the system is running, it is not recommended to remove the card while the system is running.
I never suggested that they remove the card while the system is running. You must have skipped the part in my comment that says
power off and swap the cards
Only that your newfound time from not having to fuck with video drivers might be enough to solve world peace.
Short answer is that you don’t have to do anything.
Slightly longer answer is that you can remove all existing nvidia packages, with any boot parameters they may have required, call it a day.
Also, install the generic or AMD specific packages now. Eg. vulkan-radeon or amdvlk instead of nvidia-utils (https://wiki.archlinux.org/title/Vulkan)
Yep. When I switched out my Nvidia for AMD it was as plug-and-play as it gets.
I just did this with an RX7900TX and everything worked fine and I decided to install my normal updates. And then my PC wouldn’t boot. After hours of “fun”, it turns out that the issue had nothing to do with the GPU swap and all. Tons of fun!
In case others are interested on the general compute aspect, e.g inference for self hosted AI, here is something related I found :
- ZLUDA, for CUDA everywhere, https://github.com/vosen/ZLUDA/ unfortunately in the process of a major rewrite https://github.com/vosen/ZLUDA/discussions/261 due to AMD (somehow?!) not wanting their code being used in there (maybe they did some shady RE on NVIDIA work?)
- AMD ROCm https://github.com/ROCm/ROCm and HIP https://github.com/ROCm/HIP
If no one minds my hyjacking part of this thread.
Id also like some similar advice.
I use blender. Not heavily but have been playing on it for 20plus years.
My GPU is pretty old. 1050ti at the time nvidia was pretty much it for blender.
Im looking for a sub £300 card in the next 3 to 6 months.
Is AMD well supported by blender now. And what cards would folks recomend these days.
PS not a gamer. 0ad is about as close as i get.
Linux is a monolithic kernel. This means it includes all kernel modules. You can configure the kernel to only compile with a limited set of modules, but it is not necessary unless you have specific security requirements for hardening security and redundant surface area vulnerabilities. Pretty much all distros ship a kernel with a large number of modules enabled in order to make the kernel just work for the vast majority of user hardware.
This is not some optimisations thing like you might initially think. Kernel modules are nothing like a micro kernel (Windows) with drivers. A micro kernel makes a static API spec for drivers and then documents and does nothing further. A monolithic kernel creates support for all existing hardware that is practically possible. Almost all hardware is supported within a general module that encompasses more like a standard, i.e. keyboards work like this so all keyboards are supported in a module like that. There are extra modules when some hillbilly backwards inbred hardware manufacturer makes something stupid that does not conform to industry standards, but these are not too common. The biggest issue is always completely undocumented garbage hardware that the community reverse engineers.
Anyways, you likely already have a bunch of modules you are not actually using. It probably won’t hurt to just leave it in and do nothing.
Is there a particular reason for ditching the 3080? I have the laptop 16 GB Ti version and have thought about getting the desktop version to do split AI loads.
The drivers are infinitely better, and the stutter when creating a ton of windows (ie notification spam from kconnect) is basically gone.
There isn’t anything you need to know. It’s the opposite actually. You can now forget about graphics drivers entirely if you want. Unless it’s like, a job or hobby or something.
Do you do AI stuff?
I’ve heard NVidia is better for AI
For gaming, you’ll probably not notice a difference. If anything, you’ll be happy due to not having to wrestle NVidia Linux Drivers :P
Went from GTX970 to 6800XT.
Just drivers!I think the only thing to keep in mind is that Nvidias proprietary drivers work better for Linux whereas for AMD it is the open-source ones.
I have an Nvidia card and the prop. drivers have worked flawlessly for me for years.
I know the open source drivers are closing the gap for Nvidia, and they also seem to be playing ball on that front. But for AMD the open source drivers are definitely the way to go from what I understand.
Seems weird to replace a 3080 but hey, whatever floats your goat.
I switched from Nvidia to AMD recently. As long as you have a recent kernel you should be fine. If you’re running an old/stable distro you might have issues with mesa, especially if you need OpenCL or ROCm. For general use and gaming it worked for me with no fuss.
I just replaced my 3070 with a RX 7900XT and it was a very noticeable difference in performance. It doesn’t help that my primary display is 3840x1600 though. The 3070 was never particularly great for that res.
