In the end the new GeForce RTX 4060 graphics card ended out just slightly above the Radeon RX 7600 in terms of overall performance. The Radeon RX 6000/7000 series on their open-source Linux GPU driver stack continue to perform very competitively with the NVIDIA GeForce RTX 30/40 series and their respective proprietary driver stack. Thanks to the work by AMD, Valve, Red Hat, and other parties on the open-source Radeon Linux driver stack the Linux gaming scene continues to become quite vibrant while NVIDIA also continues providing their first-rate binary Linux driver support on Linux that remains in excellent shape largely due to the shared driver code-base with Windows.
Yeah, I also remember, my particular model did worked with open source drivers, but it had a shitty performance. That’s why 2011 was the last time I bought an AMD GPU, however since today their driver is open I’m seriously considering buying an AMD next, exactly because what happened with AMD back then can happen to NVIDIA now (but not to AMD since their drivers are open and can be community-maintained if they dropped support in the future)
