NVIDIA Announces Turing-Powered Quadro RTX Family
 

Alongside today’s announcement of their new Turing GPU architecture, NVIDIA has also announced the first three products that will use the first Turing GPU. Breaking from tradition, NVIDIA has announced the workstation-class Quadro parts first. Part of the new Quadro RTX family, the Quadro RTX 8000, RTX 6000, and RTX 5000 are NVIDIA’s fastest workstation cards yet, and are set to arrive in the fourth quarter of this year.

For complete details on the Turing architecture, please see our companion article. But in short Turing is an evolution of the Volta architecture, taking everything that made the GV100 fast, and then improving on it. For professional visualization (ProViz) users, the big news here is that the cards feature hardware ray tracing acceleration, thanks to the combination of NVIDIA’s new RT cores, and the tensor cores brought over from Volta. Used together, the new cores can be used to speed up ray tracing, and then implement further post-processing tricks to cut down on the amount of work required to generate a photorealistic image.

The new GPUs and resulting Quadro cards are also the first NVIDIA cards to get GDDR6 memory – up to 48GB of it – doubling the amount of memory available versus NVIDIA’s Quadro P6000, and also offering a significant bandwidth increase at the same time. Going one step further, NVIDIA has also included support for NVLink, their proprietary multi-GPU cache coherent interlink, which will allow Quadro RTX cards to be installed in pairs and share their frame buffer memory. NVLInk isn’t as good as local memory, but with a reported 100GB/sec of bandwidth between the two cards, it’s also nothing to sneeze at.

As a result of these features NVIDIA is aiming very hard at the visual effects industry (e.g. movie and TV production), as they are some of the most demanding users in terms of performance needs, and have some of the deepest pockets as well. NVIDIA of course is no stranger to this market, but this is the biggest play they’ve ever made for it. They greatly want to bend users away from CPU-based ray tracing farms and on to more compact GPU farms.

This also means that NVIDIA has been pushing very hard behind the scenes to get software ready for their cards and the underlying RTX ray tracing functionality. While we’re still in the very early days, NVIDIA has already lined up Autodesk, Adobe, the Chaos Group, Dassault Systèmes, and of course Epic Games (among others) to support the technology in some fashion. There’s still a definite chicken-or-the-egg element in play, but NVIDIA is making a concentrated effort to get the proverbial eggs out there.
