Nvidia RTX (also known as Nvidia GeForce RTX under the GeForce brand) is a professional visual computing platform created by Nvidia, used in mainstream PCs for gaming as well as being used in workstations for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production (especially under the RTX PRO and formerly Quadro RTX brands).
Nvidia RTX features hardware-enabled real-time ray tracing. Historically, ray tracing had been reserved to non-real time applications (like CGI in visual effects for movies and in photorealistic renderings), with video games having to rely on direct lighting and precalculated indirect contribution for their rendering. RTX facilitates a new development in computer graphics of generating interactive images that react to lighting, shadows and reflections.[1] RTX runs on Nvidia Volta-, Turing-, Ampere-, Ada Lovelace- and Blackwell-based GPUs, specifically utilizing the Tensor cores (and new RT cores on Turing and successors) on the architectures for ray-tracing acceleration.[2][3][4]
In March 2019, Nvidia announced that selected GTX 10 series (Pascal) and GTX 16 series (Turing) cards would receive support for subsets of RTX technology in upcoming drivers, although functions and performance will be affected by their lack of dedicated hardware cores for ray tracing.[5]
In October 2020, Nvidia announced Nvidia RTX A6000 as the first Ampere-architecture-based graphics card for use in professional workstations in the Nvidia RTX product line, replacing the former Quadro product line of professional graphics cards.[6]
Nvidia worked with Microsoft to integrate RTX support with Microsoft's DirectX Raytracing API (DXR). RTX is currently available through Nvidia OptiX and for DirectX. For the Turing and Ampere architectures, it is also available for Vulkan.[7]
In addition to ray tracing, RTX includes artificial intelligence integration, common asset formats, rasterization (CUDA) support, and simulation APIs. The components of RTX are:[8]
In computer graphics, ray tracing generates an image by tracing rays cast through pixels of an image plane and simulating the effects of its encounters with virtual objects. This enables advanced effects that better reflect real-world optical properties, such as softer and more realistic shadows and reflections, as compared to traditional rasterization techniques which prioritize performance over accuracy.[9]
Nvidia RTX achieves this through a combination of hardware and software acceleration. On a hardware level, RTX cards feature fixed-function "RT cores" that are designed to accelerate mathematical operations needed to simulate rays, such as bounding volume hierarchy traversal. The software implementation is open to individual application developers. As ray-tracing is still computationally intensive, many developers choose to take a hybrid rendering approach where certain graphical effects, such as shadows and reflections, are performed using ray-tracing, while the remaining scene is rendered using the more performant rasterization.[10]
Nvidia OptiX is part of Nvidia DesignWorks. OptiX is a high-level, or "to-the-algorithm" API, meaning that it is designed to encapsulate the entire algorithm of which ray tracing is a part, not just the ray tracing itself. This is meant to allow the OptiX engine to execute the larger algorithm without application-side changes.
Aside from computer graphics rendering, OptiX also helps in optical and acoustical design, radiation and electromagnetic research, artificial intelligence queries and collision analysis.
Chat with RTX is an AI-based assistant that runs locally on the user's Windows PC.[11][12] It uses a large language model and requires an RTX 30, 40 or 50 series GPU with at least 8GB of VRAM.[12] It can be downloaded from Nvidia's website.
RTX Remix is a game modding platform designed by Nvidia to remaster older titles by implementing modern technologies such as ray tracing, DLSS, and enhanced assets.[13]
Nvidia has released many cards that support RTX, including the 20, 30, 40, and 50 series:[14]

The GeForce RTX 50 series of consumer graphics cards is the successor of Nvidia's GeForce 40 series. Announced at CES 2025, it debuted with the release of the RTX 5070, RTX 5080 and RTX 5090 in January 2025. It is based on Nvidia's Blackwell architecture featuring Nvidia RTX's fourth-generation RT cores for hardware-accelerated real-time ray tracing, and fifth-generation deep learning–focused Tensor Cores. The GPUs are manufactured by TSMC on a custom 4N process node.
Volta is the codename, but not the trademark, for a GPU microarchitecture developed by Nvidia, succeeding Pascal. It was first announced on a roadmap in March 2013, although the first product was not announced until May 2017. The architecture is named after 18th–19th century Italian chemist and physicist Alessandro Volta. It was Nvidia's first chip to feature Tensor Cores, specially designed cores that have superior deep learning performance over regular CUDA cores. The architecture is produced with TSMC's 12 nm FinFET process. The Ampere microarchitecture is the successor to Volta. The first graphics card to use it was the datacenter Tesla V100, e.g. as part of the Nvidia DGX-1 system. It has also been used in the Quadro GV100 and Titan V. There were no mainstream GeForce graphics cards based on Volta. After two USPTO proceedings, on July 3, 2023 Nvidia lost the Volta trademark application in the field of artificial intelligence. The Volta trademark owner remains Volta Robots, a company specialized in AI and vision algorithms for robots and unmanned vehicles.
Turing is the codename for a graphics processing unit (GPU) microarchitecture developed by Nvidia. It is named after the prominent mathematician and computer scientist Alan Turing. The architecture was first introduced in August 2018 at SIGGRAPH 2018 in the workstation-oriented Quadro RTX cards, and one week later at Gamescom in consumer GeForce 20 series graphics cards. Building on the preliminary work of Volta, its HPC-exclusive predecessor, the Turing architecture introduces the first consumer products capable of real-time ray tracing, a longstanding goal of the computer graphics industry. Key elements include dedicated artificial intelligence processors ("Tensor cores") and dedicated ray tracing processors ("RT cores"). Turing leverages DXR, OptiX, and Vulkan for access to ray tracing. In February 2019, Nvidia released the GeForce 16 series GPUs, which utilizes the new Turing design but lacks the RT and Tensor cores. Turing is manufactured using TSMC's 12 nm FinFET semiconductor fabrication process. The high-end TU102 GPU includes 18.6 billion transistors fabricated using this process. Turing also uses GDDR6 memory from Samsung Electronics, and previously Micron Technology.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
