Nvidia has finally unveiled its new GPU architecture - codenamed Turing - with three products designed primarily for the professional market, while teasing the upcoming reveal of next-gen gaming graphics cards - where they may be a couple of surprises in store.
At this year's Siggraph, Nvidia boss Jen-Hsun Huang unveiled three Nvidia Quadro RTX cards - the RTX 8000, RTX 6000 and RTX 5000 - built from two different Turing GPUs, with 4608 and 3072 CUDA cores respectively. The design appears to be a significant evolution from the Volta architecture seen in the Titan V, retaining the deep-learning AI Tensor cores, and doubling down on dedicated ray-tracing hardware.
As expected, there's significant change in the nature and performance of the attached VRAM too, with both of the new processors paired with new GDDR6 memory. The 'big chip' offering delivers 672GB/s of bandwidth vs the 448GB/s for the second-tier product. For comparison's sake, the current GTX 1080 Ti delivers a higher 484GB/s of bandwidth. Although not confirmed officially, it's almost certain that the higher performance chip runs on a 384-bit memory interface, up against a 256-bit bus on its stablemate in the RTX 5000.
