The GeForce 9 series (also known as the GeForce 9000 series) is the ninth generation of Nvidia's GeForce line of graphics processing units, the first of which was released on February 21, 2008. The products are based on an updated Tesla microarchitecture, adding PCI Express 2.0 support, improved color and z-compression, and built on a 65 nm process, later using 55 nm process to reduce power consumption and die size (GeForce 8 G8x GPUs only supported PCIe 1.1 and were built on 90 nm process or 80 nm process).
