The GeForce 300 series is a series of Tesla-based graphics processing units developed by Nvidia, first released in November 2009. Its cards are rebrands of the GeForce 200 series cards, available only for OEMs. All GPUs of the series support Direct3D 10.1, except the GT 330 (Direct3D 10.0).
On November 27, 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. [1]
On February 2, 2010, Nvidia announced the release of the GeForce GT 320, GT 330 and GT 340, available to OEMs only. [2] The Geforce GT 340 is simply a rebadged GT 240, sharing exactly the same specifications, while the GT 320 and 330 were newer cards (albeit still based on the previous generation GT200b and G92b architecture). [2]
The GeForce GT 340, holds a unique position in the history of graphics cards due to its relative rarity. Released primarily for Original Equipment Manufacturers (OEMs), the GT 340 wasn't widely available to general consumers, making it less common in the mainstream market. One intriguing aspect of the GT 340 is its unofficial rebranding by some enthusiasts. These modders took the original GT 340, enhanced its cooling capabilities, modified the BIOS, and overclocked it, creating what they termed the "GTX 340." This variant, although unofficial, became even rarer than the original due to its limited production and unique modifications. [3] [4] [5]
