Ubuntu - GPU - AMD vs Nvidia

	AMD	Nvidia
Account	No need to have an account or register	The need to have an account and be logged in.
Advertisements	No Ads When Installing Drivers.	Ads showing while it is installing.
Driver stack	Open source.	Proprietary.
Performance & Security	X.Org or Wayland can be easily used.	NVIDIA relies on X.Org for displaying graphics on Linux.
	AMD adapts to newer technologies such as Wayland to offer better performance, code maintainability, and security.	NVIDIA tries to work around this by using XWayland, which is an X server that runs under Wayland and provides compatibility for native X11 applications that are yet to provide Wayland support.
		* XWayland uses X as the display server, so it does not have Wayland’s security features.
		* There is “degraded performance” with XWayland on NVIDIA compared to X11.
		* Some applications may not work on XWayland due to it not being fully backward-compatible with X11.
Security issues	Anyone can fix.	At the mercy of Nvidia to fix. There is no one else to wait for other than Nvidia. They could take ages to fix.
Upgrading the distro	No need to remove the old driver.	Need to remove the old driver.
Vendor Lock-in	No Vendor Lock-In.	Substantial Vendor Lock-in.
