Revolutionary Realtime Ray Tracing Acceleration
Incorporating new hardware-based ray tracing engines, Turing is the industry’s first graphics processor enabling real-time ray tracing. A single NVIDIA Quadro RTX 4000 board can render complex professional models with physically accurate shadows, reflections, and refractions to empower users with instant insight. Working in concert with applications leveraging APIs such as NVIDIA OptiX, Microsoft DXR and Vulcan ray tracing, systems based on NVIDIA Quadro RTX 4000 will power truly interactive design workflows to provide immediate feedback for unprecedented levels of productivity.
RT Cores
New dedicated hardware-based ray-tracing technology allows the GPU for the first time to real-time render film quality, photorealistic objects and environments with physically accurate shadows, reflections, and refractions. The real-time ray-tracing engine works with NVIDIA OptiX, Microsoft DXR, and Vulkan APIs to deliver a level of realism far beyond what is possible using traditional rendering techniques. RT cores accelerate the Bounding Volume Hierarchy (BVH) traversal and ray casting functions using low number of rays casted through a pixel.
Enhanced Tensor Cores
New mixed-precision cores purpose-built for deep learning matrix arithmetic, delivering 8x TFLOPS for training, compared to previous generation. NVIDIA Quadro RTX 4000 utilizes 288 Tensor Cores; each Tensor Core performs 64 floating point fused multiply-add (FMA) operations per clock, and each SM performs a total of 1024 individual floating point operations per clock. In addition to supporting FP16/FP32 matrix operations, new Tensor Cores added INT8 (2048 integer operations per clock) and experimental INT4 and INT1 (binary) precision modes for matrix operations.
Mesh Shading
Provides a compute-based geometry pipeline to speed processing and culling for geometrically complex models and scenes to improve performance by up to 2x.
Motion Adaptive Shading
Offers more granular control over how GPU horsepower is distributed (i.e. more cycles applied on the detailed areas of a scene and fewer on the less detailed areas) to increase performance and at the same image quality, or produce similar image quality with a 50% reduction in the time required to generate shaded pixels.
Variable Rate Shading (VRS)
More control over pixel shading rate; efficient for effects like motion blur and foveated shading. This capability enables shading and geometry samples to process at different rates for more efficient execution.
Texture Space Shading
Decouples shading from screen space, improving shading efficiency and reuse.
Multi-View Rendering (MVR)
Extension of Single Pass Stereo rendering multiple views in a single pass with unique view origin positions or view directions.
High Speed GDDR6 Memory
Built with Turing’s vastly optimized 8 GB GDDR6 memory subsystem for the industry’s fastest graphics memory (416 GB/s peak bandwidth), NVIDIA Quadro RTX 4000 is the ideal platform for latency-sensitive applications handling large datasets.
H.264 and HEVC Encode/Decode Engines
Deliver faster than real-time performance for transcoding, video editing, and other encoding applications with a dedicated H.264 and HEVC encode engines and a dedicated decode engine that are independent of 3D/compute pipeline.
TURING VR
Ray tracing and variable rate shading enhance visual quality, while Multi-view rendering provides wider field of view, support for next-generation HMDs and displays. The RT Cores provide for accurate acoustic simulations and VirtualLink makes VR setup easier than ever with a single cable connection.
