NVIDIA GeForce GT 425M Gaming: Windows 7 Ultimate vs. Ubuntu 10.10

The GeForce GT 425M is one of NVIDIA's newest GPUs that launched in early September and is based upon their Fermi architecture for notebooks and small form factor devices such as the ASRock Vision 3D computer. The GT 425M supports technologies such as PhysX, 3D Vision, and Optimus. The Optimus technology allows seamless switching between GPUs, but sadly, it will not come to Linux. The NVIDIA GeForce GT 425M boasts 96 CUDA cores, 560MHz core clock, 1120MHz shader clock, and 1024MB of dedicated DDR3 memory clocked at 800MHz with a 128-bit interface. The other new Fermi-based notebook GPUs from NVIDIA include the GeForce GT 415M, GT 420M, GT 435M, GT 445M GTX 460M, and GTX 470M.

The ASRock Vision 3D system we are using for this comparison has an Intel Core i3 370M clocked at 2.40GHz (32nm, dual-core + Hyper Threading, 3MB of L3 cache, 35W TDP), ASRock HM55 motherboard, the GeForce GT 425M, 4GB of DDR3-1066MHz system memory, Blu-ray combo drive, and a 500GB 7200RPM Serial ATA 2.0 hard drive. The NVIDIA driver in use on the Windows side was their 260.66 driver release and on the Linux side was the 260.19.06 release. The open-source Nouveau driver does not yet provide Gallium3D support for Fermi hardware (there isn't even Fermi mode-setting support without 2D acceleration in Ubuntu 10.10 as it requires the Linux 2.6.36 kernel or later), but even if it did the performance would still be very slow...
