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.
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.
The GeForce FX or "GeForce 5" series is a line of graphics processing units from the manufacturer 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.
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.
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.
The GeForce 7 series is the seventh generation of Nvidia's GeForce graphics processing units. This was the last series available on AGP cards.
Quadro was Nvidia's brand for graphics cards intended for use in workstations running professional computer-aided design (CAD), computer-generated imagery (CGI), digital content creation (DCC) applications, scientific calculations and machine learning.
The GeForce 8 series is the eighth generation of Nvidia's GeForce line of graphics processing units. The third major GPU architecture developed by Nvidia, Tesla represents the company's first unified shader architecture.
The GeForce 900 series is a family of graphics processing units developed by Nvidia, succeeding the GeForce 700 series and serving as the high-end introduction to the Maxwell microarchitecture, named after James Clerk Maxwell. They are produced with TSMC's 28 nm process.
The GeForce 10 series is a series of graphics processing units developed by Nvidia, initially based on the Pascal microarchitecture announced in March 2014. This design series succeeded the GeForce 900 series, and is succeeded by the GeForce 16 series and GeForce 20 series using the Turing microarchitecture.
Nvidia Tesla was the name of Nvidia's line of products targeted at stream processing or general-purpose graphics processing units (GPGPU), named after pioneering electrical engineer Nikola Tesla. Its products began using GPUs from the G80 series, and have continued to accompany the release of new chips. They are programmable using the CUDA or OpenCL APIs.
The GeForce 20 series is a family of graphics processing units developed by Nvidia. Serving as the successor to the GeForce 10 series, the line started shipping on September 20, 2018, and after several editions, on July 2, 2019, the GeForce RTX Super line of cards was announced.
The GeForce 16 series is a series of graphics processing units developed by Nvidia, based on the Turing microarchitecture, announced in February 2019. The 16 series, commercialized within the same timeframe as the 20 series, aims to cover the entry-level to mid-range market, not addressed by the latter. As a result, the media have mainly compared it to AMD's Radeon RX 500 series of GPUs.
The GeForce 30 series is a family of graphics processing units developed by Nvidia, succeeding the GeForce 20 series. The series was announced on September 1, 2020 and started shipping on September 17, 2020. The cards are based on the Ampere architecture and feature hardware-accelerated raytracing (RTX) with Nvidia's second-generation RT cores and third generation Tensor Cores.
Curie is the codename for a GPU microarchitecture developed by Nvidia, and released in 2004, as the successor to Rankine microarchitecture. It was named with reference to the Polish physicist Marie Curie and used with the GeForce 6 and 7 series. Curie was followed by Tesla.
Rankine is the codename for a GPU microarchitecture developed by Nvidia, and released in 2003, as the successor to Kelvin microarchitecture. It was named with reference to Macquorn Rankine and used with the GeForce FX series.
Kelvin is the codename for a GPU microarchitecture developed by Nvidia, and released in 2001, as the successor to Celsius microarchitecture. It was named with reference to William Thomson and used with the GeForce 4 and 3 series.
Fahrenheit is the codename for a GPU microarchitecture developed by Nvidia, and released in 1998, as the successor to STG-2000, Riva 128 microarchitecture. It was named with reference to Fahrenheit and used with STG-2000, Riva 128.
