The GeForce 300 series is a family of graphics processing units developed by Nvidia based on their Tesla (microarchitecture). The first card of this series was launched in November 2009. Similar to the GeForce 100 series, the GeForce 300 series consists of re-branded video cards from the previous generation available only for OEMs. All GPUs of the series support Direct3D 10.1, except the GT 330 (Direct3D 10.0).
On 27 November 2009, Nvidia released its first GeForce 300 series video card, the GeForce 310. However, this card is a re-brand of one of Nvidia's older models (the GeForce 210) and not based on the newer Fermi architecture.
On 2 February 2010, Nvidia announced the official titles of the new generation GF100 (Fermi) cards, the GeForce GTX 470 and the GeForce GTX 480.
Later that month the company announced the release of the GeForce GT 320, GT 330 and GT 340, available to OEMs only. The Geforce GT 340 is simply a rebadged GT 240, sharing exactly the same specifications, while the GT 320 and 330 are new cards (albeit still based on the previous generation GT200b and G92b architecture).
NVIDIA ceased driver support for the GeForce 300 series on April 1, 2016.
