With the NVIDIA 590 Linux driver series removing GeForce 900 series "Maxwell" and GeForce 10 series "Pascal" as part of punting it off to the latest legacy driver branch, it's time for a last look at how the mainline NVIDIA Linux driver is performing with these aging graphics cards relative to the current state of the upstream open-source NVIDIA Linux drivers. In this article is a look at how the open-source and upstream Nouveau kernel driver with Nouveau/NVK Mesa drivers are performing relative to the NVIDIA 580 series with its Maxwell and Pascal support. For further perspective is also tossing in newer graphics cards too for providing a end-of-year GeForce 980 / 1080 / 2080 / 3080 / 4080 / 5080 series comparison between these different Linux drivers.

Early this year AMD announced the open-source GAIA project for "Generative AI Is Awesome" as a showcase of AI support atop their Ryzen AI NPUs and other hardware.

Yesterday I noted some early performance regressions I've found on the Linux 6.19 kernel compared to Linux 6.18 LTS stable. Those initial benchmarks were on an AMD EPYC server. Since then I've seen many of the same workloads regressing similarly on an AMD Ryzen Threadripper workstation between Linux 6.18 and Linux 6.19 Git. Given the significant impact and AMD Threadripper processors always helping out to speed-up Linux kernel build times to make for a quicker and more manageable kernel bisecting experience, here is a look at some of the results for the Linux 6.19 performance regressions.
