The GeForce RTX 20 Series is a family of graphics processing units developed by Nvidia, and was announced at Gamescom on 20 August, 2018.[4] It is the successor to the GeForce 10 series,[5] and launched on September 20th, 2018.[6]

Architecture

Main article: Turing (microarchitecture)

The RTX 20 series is based on the Turing microarchitecture, and features real-time raytracing.[7] This is accelerated by the use of new RT cores, which are designed to process quadtrees and spherical hierarchies, and speed up collision tests with individual triangles.

The raytracing performed by the RT cores can be used to produce reflections, refractions and shadows, replacing traditional raster techniques such as cube maps and depth maps. Instead of replacing rasterization entirely, however, the information gathered from ray-tracing can be used to augment the shading with information that is much more photo-realistic, especially in regards to off-camera action.

Tensor cores further accelerate raytracing, and are used to fill in the blanks in a partially rendered image, a technique known as de-noising. The Tensor core performs the result of deep learning on supercomputers to codify how to, for example, increase the resolution of images. In the Tensor core's primary usage, a problem to be solved is analyzed on a supercomputer, which is taught by example what results are desired, and the supercomputer determines a method to use to achieve those results, which is then done with the consumer's Tensor core. These methods are delivered "over the air" to consumers.

Development

Main article: RTX (ray tracing platform)

The ray tracing technology used in the RTX Turing GPUs was in development for 10 years.[8] RTX is the development platform introduced with the GeForce 20 series. RTX leverages Microsoft's DXR, OptiX and Vulkan for access to raytracing.[9]

  1. ^ The number of Streaming multi-processors on the GPU
  2. ^ Texture fillrate is calculated as the number of TMUs multiplied by the base core clock speed.
  3. ^ Pixel fillrate is calculated as the lowest of three numbers: number of ROPs multiplied by the base core clock speed, number of rasterizers multiplied by the number of fragments they can generate per rasterizer multiplied by the base core clock speed, and the number of streaming multiprocessors multiplied by the number of fragments per clock that they can output multiplied by the base clock rate.
