Earlier this year, Nvidia unveiled a showcase of real-time ray-tracing using Phasma and some Stormtroopers from the Star Wars franchise. At their conference in Gamescom this year, they showcased the same ray-tracing demo - but instead of running off four Volta-powered GPUs, it was powered by a single Turing-powered GPU.
The RTX 2080 Ti and RTX 2080 is only available through the Nvidia website at the time of writing, and will set users back $1899 and $1199 respectively. The RTX 2070, which is available internationally for €569, would retail for $899 through the Nvidia website. Only the RTX 2080 Ti and RTX 2080 would be "on-shelf" from September 20; stock of the RTX 2070 is not available at the time of writing.
Update: The site also said there was stock of the RTX 2080 Ti and 2080 available, although the links have since been taken down. An image of the prices from the Nvidia Australian site is reproduced below.
Update #2: NVIDIA just announced prices that were a few hundred dollars cheaper than what was listed on their own website. The RTX listings for the cards have since been taken down.
Update #3: Prices have popped back up on the Nvidia website - very briefly - revealing that the RTX 2070 would sell for $899 locally:
The non-Founders Edition versions of the cards, which aren't available through the Nvidia website, start from $US499 internationally.
The RTX 2080 Ti, 2080 and 2070 GPUs also ship with a new feature set that includes:
• The NGX neural graphics framework to incorporate AI algorithms into graphics processing
• Variable rate shading to allow shaders to concentrate GPU processing power into the most demanding areas of an image, rather than having to spread GPU power evenly across an entire screen if not needed
• GDDR6 memory
• 13-blade dual axial fans on the Founders' Edition cards for 3x the airflow
• USB Type-C and VirtualLink support
• Tensor Cores for deep neural network processing
Here's the RTX 2080 Ti, compared with the non-Founders Edition of the card and the GTX 1080 Ti:
And the specs for the RTX 2080 Founders Edition and non-Founders:
Here's the RTX 2070 Founders Edition and reference card specs. Note that the RTX 2070 only requires a single 8-pin connector, and has a noticeably lower TDP than the other two cards.
Nvidia CEO Jen Hsun Huang said the GPUs were designed for "maximum overclocking". The RTX 2080 Ti would ship with 11GB of memory and have 78 trillion RTX-OPS and 10 Giga Rays/s of performance.
The presentation was punctuated with a host of detailed explanations about different lighting techniques, real-time ray tracing, and other rendering techniques. It was a lead-up to talk about the technologies powering the company's new series of GPUs, which were leaked by AIB partners and retailers beforehand.
A large part of the reveal involved discussion of new technologies and interfaces, including DLSS, which enables a new form of anti-aliasing that's more accurate than temporal anti-aliasing.
Nvidia also showed off the Unreal Engine Infiltrator demo running at 60 FPS, although Nvidia CEO Jen-Hsun Huang noted that it could run the demo at 72 FPS (but the screen was locked to 60 FPS). A GTX 1080 Ti, Huang noted, could only run the Infiltrator demo at approximately 30 FPS.
Scenes from Metro Exodus, Assetto Corsa, Shadow of the Tomb Raider then played, showcasing the difference in reflections, global illumination, screen space reflections, and hard shadows with RTX effects enabled and disabled.
In Shadow of the Tomb Raider, for instance, an early sequence of the game takes Lara through a town square as she follows a couple of enemies. The demo showcased the difference in how colour blends with shadows with RTX enabled, and how the hard shadows collide when disabled.
