Nvidia RTX (also known as Nvidia GeForce RTX under the GeForce brand) is a professional visual computing platform created by Nvidia, primarily used in workstations for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production, as well as being used in mainstream PCs for gaming.
Roth extended the framework, introduced the term ray casting in the context of computer graphics and solid modeling, and in 1982 published his work while at GM Research Labs. [ 11 ] Turner Whitted was the first to show recursive ray tracing for mirror reflection and for refraction through translucent objects, with an angle determined by the ...
In September 2018, Nvidia introduced their GeForce RTX and Quadro RTX GPUs, based on the Turing architecture, with hardware-accelerated ray tracing using a separate functional block, publicly called an "RT core". This unit is somewhat comparable to a texture unit in size, latency, and interface to the processor core.
Die shot of the TU104 GPU used in RTX 2080 cards Die shot of the TU106 GPU used in RTX 2060 cards Die shot of the TU116 GPU used in GTX 1660 cards. The Turing microarchitecture combines multiple types of specialized processor core, and enables an implementation of limited real-time ray tracing. [4]
The RTX 4090 features 128 RT cores compared to the 84 in the previous generation RTX 3090 Ti. These 128 RT cores can provide up to 191 TFLOPS of compute with 1.49 TFLOPS per RT core. [ 14 ] A new stage in the ray tracing pipeline called Shader Execution Reordering (SER) is added in the Lovelace architecture which Nvidia claims provides a 2x ...

It might seem like a simple question. But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering. But that same ...
DLSS 3.0 makes use of a new generation Optical Flow Accelerator (OFA) included in Ada Lovelace generation RTX GPUs. The new OFA is faster and more accurate than the OFA already available in previous Turing and Ampere RTX GPUs. [29] This results in DLSS 3.0 being exclusive for the RTX 40 Series. At release, DLSS 3.0 does not work for VR displays.
