The ray tracing 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. This can only be utilized on games that support ray-tracing, which led to some controversy at launch because few games supported the feature at the time. The second-generation Tensor cores (succeeding Volta's) work in cooperation with the RT cores, and are used to fill in the blanks in a partially ray traced image, a technique known as de-noising. Another of the applications of the Tensor cores is a new method to replace anti-aliasing called DLSS (deep learning super-sampling).[9] The Tensor cores perform the result of deep learning on supercomputers to codify how to, for example, increase the resolution of images. In the Tensor cores' 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 cores. These methods are delivered "over the air" to consumers. New features in Turing:
Nvidia segregates the GPU dies for Turing into A and non-A variants, which is appended or excluded on the hundreds part of the GPU code name. Non-A variants are not allowed to be factory overclocked, whilst A variants are.[11] Development platform{{main|Nvidia RTX}}Nvidia RTX is the development platform introduced with the GeForce 20 series. RTX uses Microsoft's DXR, Nvidia's OptiX, and Vulkan for access to ray tracing.[12] The ray tracing technology used in the RTX Turing GPUs was in development at Nvidia for 10 years.[13] Chipset table
