GeForce Range of GPUs by Nvidia

GeForce is a brand of graphics processing units (GPUs) designed by Nvidia. As of the GeForce 30 series, there have been seventeen iterations of the design. The first GeForce products were discrete GPUs designed for add-on graphics boards, intended for the high-margin PC gaming market, and later diversification of the product line covered all tiers of the PC graphics market, ranging from cost-sensitive GPUs integrated on motherboards, to mainstream add-in retail boards. Most recently, GeForce technology has been introduced into Nvidia's line of embedded application processors, designed for electronic handhelds and mobile handsets.

GeForce 256 GPU by Nvidia

The GeForce 256 is the original release in Nvidia's "GeForce" product-line. Announced on August 31, 1999 and released on October 11, 1999, the GeForce 256 improves on its predecessor by increasing the number of fixed pixel pipelines, offloading host geometry calculations to a hardware transform and lighting (T&L) engine, and adding hardware motion compensation for MPEG-2 video. It offered a notably large leap in 3D PC gaming performance and was the first fully Direct3D 7-compliant 3D accelerator.

GeForce 2 series Series of GPUs by Nvidia

The GeForce 2 series (NV15) is the second generation of Nvidia's GeForce graphics processing units (GPUs). Introduced in 2000, it is the successor to the GeForce 256.

GeForce 4 series Series of GPUs by Nvidia

The GeForce 4 series refers to the fourth generation of GeForce-branded graphics processing units (GPUs) manufactured by Nvidia. There are two different GeForce4 families, the high-performance Ti family, and the budget MX family. The MX family spawned a mostly identical GeForce4 Go (NV17M) family for the laptop market. All three families were announced in early 2002; members within each family were differentiated by core and memory clock speeds. In late 2002, there was an attempt to form a fourth family, also for the laptop market, the only member of it being the GeForce4 4200 Go (NV28M) which was derived from the Ti line.

GeForce 6 series Series of GPUs by Nvidia

The GeForce 6 series is Nvidia's sixth generation of GeForce graphic processing units. Launched on April 14, 2004, the GeForce 6 family introduced PureVideo post-processing for video, SLI technology, and Shader Model 3.0 support.
