Last month AMD officially announced its RDNA 2-based flagship Big Navi graphics cards, the Radeon RX 6900XT, RX 6800XT and RX 6800, respectively. Even though the RDNA 2 Live event showcased benchmarks that favored the Radeon RX 6900 XT, Radeon RX 6800 XT, and Radeon RX 6800 over the competition, none of them included metrics related to ray tracing.
A lot of gamers have been waiting to hear about AMD’s approach to Ray Tracing. Recently a statement from AMD was also published by AdoredTV, where the manufacturer has confirmed that it will support ray tracing in all games that do not come with proprietary APIs and extensions, such as NVIDIA DirectX RTX or NVIDIA Vulkan RTX.
AMD confirmed that they would be only supporting the industry standards, which basically includes Microsoft’s DXR API and Vulkan’s Ray tracing API.
“AMD will support all ray tracing titles using industry-based standards, including the Microsoft DXR API and the upcoming Vulkan raytracing API. Games making of use of proprietary raytracing APIs and extensions will not be supported.”— AMD marketing.
Both Microsoft DXR or Vulcan ray tracing API industry standards are slowly getting more popular, and the launch of AMD’s RX 6000-series GPUs will also push game developers away from NVIDIA’s in-house implementation, or proprietary APIs.
In a recent interview with TheStreet, AMD’s Executive Vice President, Computing and Graphics Business Group, Rick Bergman also shared some details on the Ray tracing performance, and AMD’s approach to a super sample resolution technique for their upcoming Radeon RX 6000-series RDNA 2 GPU lineup.
According to Rick Bergman, AMD’s RX 6000 RDNA 2 GPU ray tracing performance goal is at 1440p screen resolution. AMD is targeting 1440p as the standard resolution for its ray-tracing solution. Rick Bergman also hinted at a new RDNA 2 GPU feature dubbed as FSR/FidelityFX Super Resolution which happens to be AMD’s response to Nvidia’s DLSS technique.
The slide shows the Ray tracing performance FPS figures of 5 PC games, Battlefield V, Call of Duty MW, CRYSIS Remastered, Metro Exodus and Shadow of the Tomb Raider, as tested by AMD.
The games have been benchmarked on 1440p screen resolution. The testing was done on the AMD Ryzen 9 5900X CPU platform along with 16GB DDR4-3200 memory on Ultra Game settings.
In Battlefield V, the RX 6800 XT provides 70 frames per second on average, with ULTRA DXR ON settings. Call of Duty Modern Warfare gives an average of around 95 FPS, once again on ULTRA DXR ON settings.
In Crysis Remastered an average of 90 FPS was measured on HIGH Ray Tracing Quality settings. Metro Exodus on the other hand was showing an average of 67 FPS on ULTRA DXR ON settings, which is the lowest score in this particular slide, since this game is obviously very demanding on the hardware.
Finally, in Shadow of the Tomb Raider, AMD claims the RX 6800 XT will offer 82 FPS on average on HIGHEST DXR Ultra settings.
In case you didn’t know, AMD Radeon RX 6000 series feature Ray Accelerators. One official slide elaborates on the hardware component that Radeon RX 6000 Series GPUs leverage for ray tracing – the Ray Accelerator (RA). Each Compute Unit carries one Accelerator as shown below:
These RA units are responsible for the hardware acceleration of ray tracing in games. The RX 6900 XT features 80 RAs, RX 6800 XT features 72, and RX 6800 has 60. The same Ray Accelerators can be found in RDNA2-based next-gen gaming consoles.
“New to the AMD RDNA 2 compute unit is the implementation of a high-performance ray tracing acceleration architecture known as the Ray Accelerator,” a description reads. “The Ray Accelerator is specialized hardware that handles the intersection of rays providing an order of magnitude increase in intersection performance compared to a software implementation.” via AMD.
AMD will launch the Radeon RX 6800 and RX 6800 XT series of graphics cards on November 18th. The AMD Radeon RX 6900 XT flagship card will be available on December 8th and will cost around $999 USD.
