Nvidia Reveals Turing GPU Architecture and 48GB GDDR6 Quadro RTX 8000

Written by Jon Sutton on Tue, Aug 14, 2018 11:21 AM

Putting to bed months upon months of rumours, Nvidia has officially revealed the Nvidia Turing GPU architecture. Nvidia touts Turing as its single greatest leap in innovation since the advent of CUDA GPU cores in 2006, achieving the holy grail of accelerated real-time ray tracing thanks to its new RT Cores.

“Turing is NVIDIA’s most important innovation in computer graphics in more than a decade,” said Jensen Huang, founder and CEO of NVIDIA, speaking at the start of the annual SIGGRAPH conference. “Hybrid rendering will change the industry, opening up amazing possibilities that enhance our lives with more beautiful designs, richer entertainment and more interactive experiences. The arrival of real-time ray tracing is the Holy Grail of our industry.”

For SIGGRAPH, Nvidia was preoccupied with the benefits to the workstation and high-end industries, espousing the benefits of its RT Cores and Tensor Cores for AI inferencing and top-end visual effects. Thanks to these hybrid technologies, Turing can render physical simulations as 6x the speed of previous-gen Pascal.

“This is a significant moment in the history of computer graphics,” said Jon Peddie, CEO of analyst firm JPR. “NVIDIA is delivering real-time ray tracing five years before we had thought possible.”

But what does it all mean? Well, Real-Time Ray Tracing (RTX) is the big change for gamers. We’ve seen this demonstrated to excellent effect in a number of RTX demos released earlier this year, including the incredible Star Wars footage rendered in Unreal Engine 4. At the time, Nvidia said this was rendered on a $60,000 DGX station with GV100 GPUs. They lied. This was all, in fact, rendered on a single Quadro RTX GPU.

The Turing GPUs are equipped with RT Cores, mini processors which are dedicated to ray-tracing. They compute exactly how light and sound would travel within a 3D environment, producing photorealistic lighting effects. In comparison to Pascal, Turing accelerates these RTX operations by a speed of 25x. This is real-time ray tracing, and it’s happening right now and will be in consumer products.

The secondary benefit, for workstation users at least, is the Tensor Cores. These are focused on AI and deep learning and will be of great benefit for scientific and mathematics use. These are already in use in the Volta architecture used for the Titan V.

And now for the real juice - the hardware itself. For gaming graphics cards we’re going to have to wait another week, but Nvidia was prepared to announce Quadro RTX, its first ever ray-tracing GPU. A grand total of three Quadro RTX models are coming to market. This ranges from the $2300 Quadro RTX 4000, with 16GB GDDR6, all the way up to the frankly obscene $10,000 Quad RTX 8000, complete with 48GB GDDR6 (96GB With NVLink), 4608 GPU cores and 576 Tensor Cores.   

The Quadro RTX family is built from two distinct Turing GPUs, one with 4608 CUDA Cores and the other with 3072 CUDA Cores. This is actually a drop in cores compared to Nvidia previous flagship products. However, the redesign GPU and cache architecture allow for a far greater level of performance from fewer cores. This is all achieved without a process shrink, although it means a monstrously-sized 754mm2 GPU, compared to 471mm2 for the GP102 used by the Nvidia Titan Xp.

They need to disassemble it, try to put it back together, drop something, then see if Nvidia will fix it or avoid doing it like Apple xD

Why am I even reading this knowing I'll never be able to afford any of this? No point in even being curious about it tbh.

25:25 min the audience looks bored out their mind, honesty this wasn't that big, most people used cpu rendering farms anyway to get this photo realistic environment, like myself, I'll be more surprised if they can achieve something like that in 60fps world, then just one vehicle.

Yall sure this isn't a rumor, you know with all these rumor articles yall been releasing lately, just want to make sure, and i'm going take this with a grain of salt.

RTX is good and all but it won't be the defining factor for games in the next 2 years which is exactly how long the GTX / RTX 2000 series will last. I would go for an RTX card in their 3000 line up right in time for Cyberpunk 2077!

How do you know nex gen will last 2 years?, I mean current gen lasted around 2 years, but maybe this was a rare thing to happen?

Innovation is usually driven by passion.
But Nvidia is now a big business. And simple rule of business is you want to squeeze every last drop of your investment like the RTX 2000 series. And secondly, they can afford to do this as AMD has nothing to even touch their cards at least for most gamers. AMD CPUs are awesome though.

pfu... You can put so much VRAM in this one GPU, yet you literally emasculate your mainstream gpu's RAM capacity...
