GeForce 20 series
The GeForce 20 Series is a family of graphics processing units developed by Nvidia, and was announced at Gamescom on August 20, 2018. It is the successor to the GeForce 10 series, and started shipping on September 20, 2018.
The price of Nvidia GeForce 20 Series is about $349.
New features in Turing:
The RTX 20 series is based on the Turing microarchitecture and features real-time ray tracing. The cards are manufactured on an optimized 16 nm node from TSMC, named 12 nm FinFET NVIDIA (FFN). This real-time ray tracing 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 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.
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. The ray tracing technology used in the RTX Turing GPUs was in development at Nvidia for 10 years.
