GeForce is a label of graphics processing units (GPUs) created by Nvidia. By the GeForce 20 Super series, there have been sixteen iterations of the appearance. The first GeForce products have been discrete GPUs designed for add-on graphics boards, created for the high-margin PC gaming market, and later diversification of the item line covered all tiers of the PC graphics market, starting from cost-sensitive GPUs integrated on motherboards, to mainstream add-in retail boards. Lately, GeForce technology offers been introduced into Nvidia’s kind of embedded application processors, designed for electronic handhelds and mobile handsets.

The “GeForce” name originates from a contest held by Nvidia in early 1999 called “Name That Chip”. The business enterprise called out to everyone to say the successor to the RIVA TNT2 kind of graphics boards. There were over 12,000 entries received and 7 winners received a RIVA TNT2 Ultra graphics card as a motivation.
Graphics processor generations
GeForce 900 series
In March 2013, Nvidia announced that the successor to Kepler would be the Maxwell microarchitecture. It turned out released in September 2014. This is actually the last GeForce series to assist analog video output through DVI-I.
GeForce 10 series
In March 2014, Nvidia announced that the successor to Maxwell would be the Pascal microarchitecture; announced on 6 May 2016 and released on 27 May 2016. Architectural improvements will be the following:
In Pascal, an SM (streaming multiprocessor) includes 64 CUDA cores, lots identical to AMD’s GCN CU (compute unit). Maxwell packed 128, Kepler 192, Fermi 32 and Tesla simply 8 CUDA cores into an SM; the GP100 SM is normally partitioned into two processing blocks, each having 32 single-precision CUDA Cores, an instruction buffer, a warp scheduler, 2 texture mapping units and 2 dispatch units.
GDDR5X – New memory standard supporting 10Gbit/s data rates and an updated memory controller. Only the Nvidia Titan X (and Titan Xp), GTX 1080, the GTX 1080 Ti, and the GTX 1060 (6 GB Version) support GDDR5X. The GTX 1070 Ti, GTX 1070, GTX 1060 (3GB version), GTX 1050 Ti, and GTX 1050 use GDDR5.
Unified memory – A memory architecture, where the CPU and GPU can access both main system memory and memory on the graphics card with a technology called “Page Migration Engine”.
NVLink – A high-bandwidth bus in the middle of your CPU and GPU, and between multiple GPUs. Allows higher transfer speeds than those achievable by using PCI Express; approximated to provide between 80 and 200 GB/s.
16-bit (FP16) floating-point operations could possibly be executed at twice the rate of 32-bit floating-point operations (“single precision”) and 64-bit floating-point operations (“double precision”) executed at half the rate of 32-bit floating point operations (Maxwell 1/32 rate).
GeForce 20 series and 16 series
In August 2018, Nvidia announced the GeForce successor to Pascal. The newest microarchitecture name was revealed as “Turing” at the Siggraph 2018 conference. This new GPU microarchitecture is aimed to accelerate the real-time ray tracing support and AI Inferencing. It offers a fresh Ray Tracing unit (RT Core) that may dedicate processors to the ray tracing in hardware. It supports the DXR extension in Microsoft DirectX 12. Nvidia claims the newest architecture is certainly up to 6 occasions faster when compared to older Pascal architecture. A complete fresh Tensor core design since Volta introduces AI deep learning acceleration, which allows the utilisation of DLSS (Deep learning super-sampling), a brand new kind of anti-aliasing that uses AI to provide crisper imagery with less influence on performance. Furthermore, it shifts its integer execution unit that may execute in parallel with the floating stage data path. A brand new unified cache architecture which doubles its bandwidth weighed against previous generations was also announced.
The newest GPUs were revealed as the Quadro RTX 8000, Quadro RTX 6000 and Quadro RTX 5000. The very best quality Quadro RTX 8000 features 4,608 CUDA cores and 576 Tensor cores with 48GB of VRAM. Nvidia expects the Turing-based Quadro GPU to be released on Q4 2018. Later through the Gamescom press conference, NVIDIA’s CEO Jensen Huang, unveiled the newest GeForce RTX series with RTX 2080 Ti, 2080, and 2070 that may make use of the Turing architecture. The very first Turing cards have been slated to ship to consumers on September 20, 2018. Nvidia announced the RTX 2060 on January 6, 2019 at CES 2019.
On July 2, 2019, Nvidia announced the GeForce RTX Super kind of cards, a 20 series refresh which comprises higher-spec versions of the RTX 2060, 2070 and 2080. The RTX 2070 and 2080 have been discontinued.
In February 2019, Nvidia announced the GeForce 16 series. It truly is based on the same Turing architecture within the GeForce 20 series, but omitting the Tensor (AI) and RT (ray tracing) cores unique to the latter towards providing an even more affordable graphics solution for gamers while still attaining an elevated performance compared to respective cards of the last GeForce generations.
Similar to the RTX Super refresh, Nvidia on October 29, 2019 announced the GTX 1650 and 1660 Super cards, which replaced their non-Super counterparts.
