NVIDIA ended support for their 10xx series [1]. To be clear, AMD also moved support for their equivalent 5xxx series to legacy drivers [2], but "supports their cards for many years" doesn't hold value if both companies stopped their respective GPUs at basically the same time.

Also remember that one of those 2 companies has opensource drivers for Linux for their old GPUs, while the other doesn't (newer NVIDIA GPUs have an opensource driver but this isn't the case for the 10xx series). Users of legacy NVIDIA cards needs on Linux needs to use their old driver branches, with results that are less than optimal to say the least.

This is about their FPGA tooling. It has nothing whatsoever to do with GPUs.
