NVIDIA unveiled a new generation of GPUs Turing with a specialized ray ray tracing unit RT Core (so far only in professional Quadro accelerators)

At its own event within the framework of the SIGGRAPH 2018 show, NVIDIA made the long-awaited announcement – officially unveiled the first graphics processor on architecture a new generation of Turing. A distinctive feature of the new generation GPU is the specialized RT Core compute unit for ray tracing support, an integrated technology that provides content developers with real-time rendering of cinematic quality. As usual, the introduction of a new architecture starts with a professional segment.

The California chipmaker calls the new Quadro RTX graphics accelerator the generation of Turing the first GPU with ray tracing support, and in order to separately emphasize the significance of the innovation compares it with the introduction of CUDA cores in 2006.

, a line of accelerators Quadro RTX – a professional accelerator (for workstations, servers, and so on), not gaming. The flagship Quadro RTX 8000 graphics accelerator will cost $ 10,000 after it goes on sale later this year.

The basis for the Quadro RTX 8000 is the GPU with 4608 CUDA cores, 48 ​​GB of new GDDR6 video memory and 576 Tensor Cores units. The latter are intended for calculations related to neural networks, machine and in-depth training.

As for performance, it reaches 16 TFLOPS in single-precision calculations (FP32), and in calculations of half-accuracy – 32 TFLOPS. Separately, the evaluation of the performance of blocks in the operations of machine and in-depth training – 500 TOPs (trillion tensor operations per second) is indicated. Well, the computational power of the trace is 10 GigaRays / sec.

In addition to the flagship RTX 8000, two more RTX 6000 and 5000 models were introduced, which are truncated versions of the flagship.

Quadro RTX accelerators can be combined using a bridge NVLink. In addition, they support the new VirtualLink standard that connects the VR headsets to a PC and other devices using a single USB Type-C connector.

Now it remains to wait for the announcement of the Turing generation of game adapters and evaluate in practice what the RT Core unit will give and the long-awaited ray tracing in games. Recall, the premiere of the new flagship video game card NVIDIA is expected in a week at the Gamescom 2018.
