With the Linux 3.10 kernel having been pulled recently into the Ubuntu 13.10 archive, new benchmarks have been conducted comparing the open-source Nouveau driver against the binary NVIDIA 319.32 Linux graphics driver on a NVIDIA-powered laptop.
This is just some quick weekend testing comparing the current state of Nouveau vs. the blob on Ubuntu 13.10 in its current development form. Ubuntu 13.10 right now is still running the Unity 7.0.1 desktop over an X.Org Server and is shipping the Linux 3.10 kernel with Mesa 9.1.4. Mesa 9.2 will be pulled in prior to the official Ubuntu 13.10 release, which is why this weekend testing is just a quick one-laptop benchmarking session.
Both the Nouveau and NVIDIA graphics drivers were tested in their "stock" configuration on Ubuntu 13.10. The Nouveau driver still lacks dynamic re-clocking support "out of the box" even with the Linux 3.11 kernel.
