With NVIDIA still not providing any open-source support or technical documentation for their graphics processors, for those in the open-source community who seek to use their GeForce 400/500 "Fermi" GPUs without NVIDIA's binary driver, they are left to use the reverse-engineered, community-created Nouveau driver. Fortunately, the support for the NVIDIA Fermi GPUs is coming along at a respectable pace -- with even working OpenGL acceleration -- considering that NVIDIA is providing no support at all. In this article are the first benchmarks of this experimental GeForce 400/500 "Nouveau NVC0" driver versus NVIDIA's official proprietary driver.
The GeForce 400 series launched nearly one year ago (April 2010) and just days after the GeForce GTX 470 and GeForce GTX 480 appearing, independent work began on bringing up support for this hardware in the Nouveau driver as well as within the PSCNV Nouveau driver fork. PathScale, the compiler company behind the PSCNV fork that's particularly interested in bringing up OpenCL/Compute support, even offered free Fermi graphics cards to developers.
