At SIGGRAPH 2018, Nvidia announced its first processors built on its long-awaited Turing architecture, the Quadro RTX 5000, 6000 and 8000 graphics processors; Turing brings higher-bandwidth processing thanks to 4,608 CUDA cores along with support for high-bandwidth GDDR6 memory and the new one-cable VirtualLink VR. RTX adds new ray-tracing cores for high-quality, real-time rendering with global illumination.

They're slated to be available by the end of the year.
