When having the HP Z6 G5 A workstation in the lab for benchmarking, one of the curiosity-driven tests was seeing how well the latest open-source and upstream Nouveau driver stack is competing against the latest official NVIDIA R595 driver for workstations. The official NVIDIA Linux driver stack remains the best positioned software solution for RTX (PRO) hardware but Nouveau continues evolving while awaiting the Nova kernel driver to reach the limelight.
The Nouveau driver continues to provide open-source, out-of-the-box NVIDIA graphics support on modern Linux distribution that in recent years has become more capable thanks to going the NVIDIA GPU System Processor (GSP) route for supporting Turing and newer GPUs. This has meant much better performance than previously when hitting re-clocking challenges and the like, but most users will still be best off using the official NVIDIA driver stack, now up to version 595. At least though with Nouveau+GSP means a much nicer out-of-the-box experience on fresh installs of modern Linux distributions compared to falling back to the VESA driver or obstacles in trying to launch accelerated-Wayland compositors, etc.
It will be interesting to see how the in-development Nova driver is ultimately positioned by NVIDIA relative to their current official open-source but out-of-tree kernel graphics driver, but for now Nouveau is what’s upstream and usable in the mainline Linux kernel for pure upstream open-source support. This round of testing was done with the Linux 7.0 kernel as shipped by the new Ubuntu 26.04 LTS while opting for Mesa 26.2-devel Git via the Mesa ACO PPA for easy reproducibility. On the NVIDIA official driver side was the NVIDIA 595.58.03 driver as their latest official driver release as of the testing that occurred in late April.
The HP Z6 G5 A workstation that was in the lab for review was equipped with the NVIDIA RTX PRO 6000 Blackwell Max-Q Workstation Edition and thus these Nouveau vs. NVIDIA benchmarks…
