GeForce is a Brand of PC Graphics Chipsets designed by NVIDIA . The first GeForce products were designed and marketed for the high-margin Gamer community of Computer users, but later product releases expanded the line to cover all tiers of the graphics market, from low-end to high-end. As Of 2006 , there have been seven iterations of the GeForce design. NVIDIA regularly complements their hardware with graphical Demos to display their prowess. GEFORCE CARD GENERATIONS ; although 3D games utilizing this Feature did not appear until later. Initial GeForce256 boards shipped with SDRAM memory, and later boards shipped with faster DDR memory. ; Radeon and 3dfx Voodoo 5 5500. Later, NVIDIA released the cost-reduced GeForce 2 MX. The MX retained the 3D-rendering feature set (such as hardware transformation and shading) of the flagship GTS. Available in several variants, the MX remains one of the best-selling consumer-level cards of all time. Faster versions of the GeForce 2 GTS were also released in the guise of ''Pro'', ''Ultra'', and ''Ti'' versions. ; 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. The GPU was sometimes outperformed by GeForce 2 Ultra since the Ultra had a faster core clock; however, the GeForce 3 was able to outperform the Ultra at higher resolutions and when anti-aliasing was applied due to an improved and more efficient memory controller. Technology developed for the GeForce 3 later emerged in the Microsoft Xbox game console. The initial 'vanilla' GeForce 3 was later joined by a slightly cut-down version, the ''Ti 200'', and a slightly faster version, the ''Ti 500'' (which was claimed to be around 10% faster). ; GeForce 4 : Launched in February 2002, the high-end GeForce 4 Ti (NV25) was an incremental upgrade to the GeForce 3. A later "family member," the GeForce4 MX, stirred controversy due to the MX's vastly inferior feature set. Commentators criticized the product's name, as the GeForce 4 MX was much closer functionally to an upgraded GeForce 2 (with improvements in the memory controller and video processing engine.) The GeForce 4 MX sold in huge volumes, in some cases because of customers being misled by the "GeForce 4" label, but the card was respected as a capable and relatively fast budget gaming card, despite the lack of shader technology. ; 's Radeon 9700, the FX series performed poorly on DirectX 9 shader operations — the crucial element of "cinematic rendering." In many (shader 2.0) synthetic benchmarks, the fastest FX version trailed far behind (as much as 60-70% slower) the equivalent competition from the ATI R300 series. Even after a refresh (product redesign) cycle, later FX products (such as the 5700 and 5900) still trailed far behind their R300-based counterparts. The FX series also suffered from a high level of incompatibility because of issues with the shader, although this was in many ways due to buggy drivers at the time. The GeForce FX series became a subject of controversy when it was discovered that NVIDIA had "optimized" specific drivers to work with 3D Mark 2003 , a popular benchmarking program used by print media reviewers to compare graphic cards. They had often applied pressure on the media to use these "official" drivers, implying that NVIDIA had applied a "hack" to force 3D Mark to produce better results than the card was really capable of producing, and showing the chipset as superior to ATI's Radeon 9x00 series. As a result, many websites pulled their 3D Mark 2003 results for GeForce FX cards, citing reason to believe that the results were not representative. ; (Scalable Link Interface) and PureVideo capability. GeForce 6 consists of a high-end model; the 6800Ultra, mid-end performance models (6800 GT, 6800 GS, 6800 GTO, 6800) mainstream models (6800 XT, 6800 LE, 6600 GT, 6600 DDR2, 6600) and low-end models (6600 LE, 6500, 6200, 6200 TC) and integrated models (6150, 6100). ; and transparency multisampling anti-aliasing modes (TSAA and TMAA), as well as improved rendering speed and reduced power consumption. Breaking with past traditions of the GPU market, NVIDIA timed the announcement of the GeForce 7 with immediate retail availability. All models of the GeForce 7 series are exclusively PCI-express models, except for the 7800GS, which is exclusively AGP. The GeForce 7 consists of high-end models (7900GTX, 7800 GTX 512, 7800 GTX), mid-end performance models (7900GT, 7800 GT), mainstream models (7800GS AGP, 7600GT, 7600GS) and low-end models (7300GS, 7300 LE) ; cards with native DirectX 10 capability, which is essential to fully utilitize the upcoming Microsoft Windows Vista's Aero graphical interface. MOBILE CHIPSETS Since the GeForce 2, NVIDIA has produced a number of counterpart designs for notebook computers, such as the GeForce Go, a notebook graphics processing unit (GPU). GeForce Go provides solutions for many mobile platforms including thin and light, desktop replacement, and business notebooks, as well as mobile workstations. SEE ALSO EXTERNAL LINKS |
