These APIs have also proved vital to computer graphics hardware manufacturers, as they provide a way for programmers to access the hardware in an abstract way, while still taking advantage of the special hardware of any specific graphics card.
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.
Starting from OptiX 3.5.0 a second library called OptiX Prime was added to the bundle which aims to provide a fast low-level API for ray tracing - building the acceleration structure, traversing the acceleration structure, and ray-triangle intersection. Prime also features a CPU fallback when no compatible GPU is found on the system.
The GeForce RTX, in the form of models 2080 and 2080 Ti, became the first consumer-oriented brand of graphics card that can perform ray tracing in real time, [41] and, in November 2018, Electronic Arts' Battlefield V became the first game to take advantage of its ray tracing capabilities, which it achieves via Microsoft's new API, DirectX ...
The GeForce 20 series is a family of graphics processing units developed by Nvidia. [8] Serving as the successor to the GeForce 10 series, [9] the line started shipping on September 20, 2018, [10] and after several editions, on July 2, 2019, the GeForce RTX Super line of cards was announced.
As an RTX card, even the lowest tier 2060 6GB still has full DXR and DLSS support. Okay, sure, it won't be able to run the new DLSS 3 algorithm, but that's true of all RTX 20- and 30-series cards.
All the RTX 30 GPUs are made using the 8 nm Samsung node. [37] Only the RTX 3090 and RTX 3090 Ti support 2-way NVLink. RTX 3050 feature limited 8 lanes for the PCIe 4.0 bus interface. All other cards support the full ×16 bandwidth. Double-precision performance of the Ampere chips are 1/64 of single-precision performance.
GPUOpen HIP: A thin abstraction layer on top of CUDA and ROCm intended for AMD and Nvidia GPUs. Has a conversion tool for importing CUDA C++ source. Supports CUDA 4.0 plus C++11 and float16. ZLUDA is a drop-in replacement for CUDA on AMD GPUs and formerly Intel GPUs with near-native performance. [32]
