UL Benchmarks Updates 3DMark with Ray-Tracing Feature Test

The launch of AMD Radeon RX 6000 Series graphics cards on November 18 will end NVIDIA's monopoly on real-time raytracing. For the first time, gamers will have a choice of GPU vendors when buying a raytracing-capable graphics card. Today, we're releasing a new 3DMark feature test that measures pure raytracing performance. You can use the 3DMark DirectX Raytracing feature test to compare the performance of the dedicated raytracing hardware in the latest graphics cards from AMD and NVIDIA.

Real-time raytracing is incredibly demanding. The latest graphics cards have dedicated hardware that's optimized for raytracing operations. Despite the advances in GPU performance, the demands are still too high for a game to rely on raytracing alone. That's why games use raytracing to complement traditional rendering techniques. The 3DMark DirectX Raytracing feature test is designed to make raytracing performance the limiting factor. Instead of relying on traditional rendering, the whole scene is ray-traced and drawn in one pass.

EVGA GeForce RTX 3090 KINGPIN Achieves 2.58 GHz Core Clock, Breaks World Record in 3D Mark Port Royal

[Update, September 29, 2020: We now have a good first look at the card courtesy the man himself. It confirms what we already knew, with a 360 mm AIO cooler and a flip-up OLED screen paired to the flagship offering from EVGA this generation.]

It's only been moments after the RTX 3090's release, but professional overclockers are already unleashing the power available on NVIDIA's GA-102 chip by resorting to exotic cooling techniques. Renowned overclocker Vince "K|NGP|N" Lucido, who works in close proximity with NVIDIA AIB EVGA, tamed the RTX 3090's temperature by resorting to liquid nitrogen. This, alongside tweaks to Vcore (1069 mV) allowed the card to reach a startling 2.58 GHz core clock (a staggering 52.2% increase over NVIDIA's base clock), and 10.750 MHz (21.5 Gbps) memory clocks on the GDDR6X subsystem, which in itself is a 10.3% increase over reference clocks.

The 16.673 3D Mark Port Royal score was achieved with a fully custom design made by EVGA with Vince Lucidos' input. This über 3090 ultimately delivered a performance increase of around 30% more than the stock RTX 3090 would be able to, which isn't a bad equilibrium between the core and memory clock increases. Some might say this is the performance delta one would expect between the 3090 and the 3080 (an overall 40% performance increase, considering the 3090 is already an average of 10% faster than the 3080 at stock clocks).

NVIDIA Extends DirectX Raytracing (DXR) Support to Many GeForce GTX GPUs

NVIDIA today announced that it is extending DXR (DirectX Raytracing) support to several GeForce GTX graphics models beyond its GeForce RTX series. These include the GTX 1660 Ti, GTX 1660, GTX 1080 Ti, GTX 1080, GTX 1070 Ti, GTX 1070, and GTX 1060 6 GB. The GTX 1060 3 GB and lower "Pascal" models don't support DXR, nor do older generations of NVIDIA GPUs. NVIDIA has implemented real-time raytracing on GPUs without specialized components such as RT cores or tensor cores, by essentially implementing the rendering path through shaders, in this case, CUDA cores. DXR support will be added through a new GeForce graphics driver later today.

The GPU's CUDA cores now have to calculate BVR, intersection, reflection, and refraction. The GTX 16-series chips have an edge over "Pascal" despite lacking RT cores, as the "Turing" CUDA cores support concurrent INT and FP execution, allowing more work to be done per clock. NVIDIA in a detailed presentation listed out the kinds of real-time ray-tracing effects available by the DXR API, namely reflections, shadows, advanced reflections and shadows, ambient occlusion, global illumination (unbaked), and combinations of these. The company put out detailed performance numbers for a selection of GTX 10-series and GTX 16-series GPUs, and compared them to RTX 20-series SKUs that have specialized hardware for DXR.
Update: Article updated with additional test data from NVIDIA.

NVIDIA to Enable DXR Ray Tracing on GTX (10- and 16-series) GPUs in April Drivers Update

NVIDIA had their customary GTC keynote ending mere minutes ago, and it was one of the longer keynotes clocking in at nearly three hours in length. There were some fascinating demos and features shown off, especially in the realm of robotics and machine learning, as well as new hardware as it pertains to AI and cars with the all-new Jetson Nano. It would be fair to say, however, that the vast majority of the keynote was targeting developers and researchers, as usually is the case at GTC. However, something came up in between which caught us by surprise, and no doubt is a pleasant update to most of us here on TechPowerUp.

Following AMD's claims on software-based real-time ray tracing in games, and Crytek's Neon Noir real-time ray tracing demo for both AMD and NVIDIA GPUs, it makes sense in hindsight that NVIDIA would allow rudimentary DXR ray tracing support to older hardware that do not support RT cores. In particular, an upcoming drivers update next month will allow DXR support for 10-series Pascal-microarchitecture graphics cards (GTX 1060 6 GB and higher), as well as the newly announced GTX 16-series Turing-microarchitecture GPUs (GTX 1660, GTX 1660 Ti). The announcement comes with a caveat letting people know to not expect RTX support (think lower number of ray traces, and possibly no secondary/tertiary effects), and this DXR mode will only be supported in Unity and Unreal game engines for now. More to come, with details past the break.

3DMark Adds NVIDIA DLSS Feature Performance Test to Port Royal

Did you see the NVIDIA keynote presentation at CES this year? For us, one of the highlights was the DLSS demo based on our 3DMark Port Royal ray tracing benchmark. Today, we're thrilled to announce that we've added this exciting new graphics technology to 3DMark in the form of a new NVIDIA DLSS feature test. This new test is available now in 3DMark Advanced and Professional Editions.

3DMark feature tests are specialized tests for specific technologies. The NVIDIA DLSS feature test helps you compare performance and image quality with and without DLSS processing. The test is based on the 3DMark Port Royal ray tracing benchmark. Like many games, Port Royal uses Temporal Anti-Aliasing. TAA is a popular, state-of-the-art technique, but it can result in blurring and the loss of fine detail. DLSS (Deep Learning Super Sampling) is an NVIDIA RTX technology that uses deep learning and AI to improve game performance while maintaining visual quality.

3DMark Port Royal Ray-tracing Benchmark Release Date and Pricing Revealed

UL Benchmarks released more information on pricing and availability of its upcoming addition to the 3DMark benchmark suite, named "Port Royal." The company revealed that the benchmark will officially launch on January 8, 2019. The Port Royal upgrade will cost existing 3DMark paid (Advanced and Professional) users USD $2.99. 3DMark Advanced purchased from January 8th onward at $29.99 will include Port Royal. 3DMark Port Royal is an extreme-segment 3D graphics benchmark leveraging DirectX 12 and DirectX Raytracing (DXR). UL Benchmarks stated that Port Royal was developed with inputs from industry giants including NVIDIA, AMD, Intel, and Microsoft.

UL Benchmarks Unveils 3DMark "Port Royal" Ray-tracing Benchmark

Port Royal is the name of the latest component of UL Benchmarks 3DMark. Designed to take advantage of the DirectX Raytracing (DXR) API, this benchmark features an extreme poly-count test-scene with real-time ray-traced elements. Screengrabs of the benchmark depict spacecraft entering and leaving mirrored spheres suspended within a planet's atmosphere, which appear to be docks. It's also a shout out to of a number of space-sims such as "Star Citizen," which could up their production in the future by introducing ray-tracing. The benchmark will debut at the GALAX GOC Grand Final on December 8, where the first public run will be powered by a GALAX GeForce RTX 2080 Ti HOF graphics card. It will start selling in January 2019.
