Wikipedia About GeForce
This: G force (disambiguation)
GeForce is a brand of PC graphics processor units (GPUs) designed by Nvidia. The first GeForce products were designed and marketed for the high-margin computer gamer community, but later the product's releases expanded the product line to cover all tiers of the graphics market, from low-end to high-end. As of 2008, there have been ten iterations of the design. Nvidia only designs the chips; manufacturing is outsourced. While several companies (notably, Intel) design low-end GPUs, only Nvidia's GeForce and ATI's Radeon series compete for the high-end GPU market.
Name origin
The "GeForce" name originated from a contest held by Nvidia in early 1999. Called "Name That Chip", the contest called out to the public to name the successor to the RIVA TNT2 line of graphics boards. There were over 12,000 entries received and 7 winners received a RIVA TNT2 Ultra graphics board as a reward.
Generations
- GeForce 256
- Launched on August 31 1999, the GeForce 256 (NV10) was the first PC graphics chip with hardware transform, lighting, and shading although 3D games utilizing this feature did not appear until later. Initial GeForce 256 boards shipped with SDRAM memory, and later boards shipped with faster DDR memory.
- GeForce2
- Launched in April 2000, the first GeForce2 (NV15) was another high-performance graphics chip. Nvidia moved to a twin texture processor per pipeline (4x2) design, doubling texture fillrate per clock compared to GeForce 256. Later, Nvidia released the GeForce2 MX (NV11), which offered performance similar to the GeForce 256 but at a fraction of the cost. The MX was a compelling value in the low/mid-range market segments and was popular with OEM PC manufacturers and users alike.
- GeForce3
- Launched in February 2001, the GeForce3 (NV20) introduced DirectX 8.0 programmable pixel shaders to the GeForce family. It had good overall performance and shader support, making it popular with enthusiasts although it never hit the midrange price point. A derivative of the GeForce3, NV2A, was developed for the Microsoft Xbox game console.
- GeForce4
- Launched in February 2002, the high-end GeForce4 Ti (NV25) was mostly a refinement to the GeForce3. The biggest advancements included enhancements to anti-aliasing capabilities, an improved memory controller, a second vertex shader, and a manufacturing process size reduction to increase clock speeds. Another "family member," the budget GeForce4 MX, was based on the GeForce2, with a few additions from the new GeForce4 Ti line. It targeted the value segment of the market and lacked pixel shaders.
- GeForce FX
- Officially launched in November 2002, the GeForce FX (NV30) was a huge change in architecture compared to its predecessors. The GPU was designed not only to support the new Shader Model 2 specification but also to perform well on older DirectX 7 and 8 titles. However, initial models suffered from weak floating point shader performance and excessive heat which required two-slot cooling solutions. Products in this series carry the 5000 model number, as it is the fifth generation of the GeForce, though Nvidia marketed the cards as GeForce FX instead of GeForce 5 to show off "the dawn of cinematic rendering".
