I’m running CachyOS, and having an Nvidia card, I’m using their Nvidia-specific kernel. I know this 3060 won’t last forever, and I’m planning to upgrade to an AMD card for a better overall experience.
Is there anything I should be aware of regarding the kernel or other compatibility when switching brands? Can I simply plug in the new one and run pacman -Syu?
Sidenote: I will plan around my PSU’s output, so no need to advise regarding physical compatibility.


Updated the comment. (The ICD is explicitly installed by vulkan-radeon, vulkan-intel or nvidia-utils/vulkan-nouveau. Just as with all linux-firmware categories/companies being their own package now, this is probably done to minize unused space/bloat.)
