Ray tracing, a complicated computer graphics-rendering technique that produces extremely realistic lighting effects but is difficult to achieve in real-time because it uses a lot of resources, has become more possible with the unveiling of Nvidia’s Turing architecture, according to Sam Byford, writing for The Verge. 

Simultaneous with the introduction of the Turing architecture, Nvidia showcased the Quadro RTX, which the company claims is the world’s first ever ray-tracing GPU. Nvidia is positioning the Quadro RTX not for gaming but for high-end professional use, with the flagship Quadro RTX 8000 costing as much as US$10,000. It will have 48GB of new GDDR6 memory, 4608 CUDA cores, and 576 Tensor cores. Its ray tracing capability has been pegged at 10 gigarays per second while its general performance is at 16 teraflops. It will use Nvidia’s NVLink interface for linking multiple cards and will support the new VirtualLink standard for virtual reality headsets that use a single USB-C cable. 

The rollout of the Quadro RTX GPU is expected to radically upgrade the work of 50 million designers and artists by allowing them to create photorealistic scenes in real time and incorporating artificial intelligence capabilities to their creation at the same time. 

Unveiled together with the RTX GPUs is the Quadro RTX Server, a reference architecture for highly configurable, on-demand rendering and virtual workstation solutions. On the other hand, the Quadro RTX GPUs are equipped with new RT cores for real-time tracing of objects and environments. The Turing Tensor cores, for their part, are capable of accelerating deep neural network training and inference. They also have 4608 CUDA cores that can produce 16 trillion floating point operations in parallel with 16 trillion integer operations per second for simulating physical experiments.
