Today, AMD (NASDAQ: AMD) unveiled the AMD Radeon™ RX 6000 Series graphics cards, delivering powerhouse performance, incredibly life-like visuals, and must-have features that set a new standard for enthusiast-class PC gaming experiences. Representing the forefront of extreme engineering and design, the highly anticipated AMD Radeon™ RX 6000 Series includes the AMD Radeon™ RX 6800 and Radeon™ RX 6800 XT graphics cards, as well as the new flagship Radeon™ RX 6900 XT – the fastest AMD gaming graphics card ever developed.
AMD Radeon™ RX 6000 Series graphics cards are built upon groundbreaking AMD RDNA™ 2 gaming architecture, a new foundation for next-generation consoles, PCs, laptops and mobile devices, designed to deliver the optimal combination of performance and power efficiency. AMD RDNA™ 2 gaming architecture provides up to 2X higher performance in select titles with the AMD Radeon™ RX 6900 XT graphics card compared to the AMD Radeon™ RX 5700 XT graphics card built on AMD RDNA™ architecture, and up to 54 percent more performance-per-watt when comparing the AMD Radeon™ RX 6800 XT graphics card to the AMD Radeon™ RX 5700 XT graphics card using the same 7nm process technology.
AMD RDNA™ 2 offers a number of innovations, including applying advanced power saving techniques to high-performance compute units to improve energy efficiency by up to 30 percent per cycle per compute unit, and leveraging high-speed design methodologies to provide up to a 30 percent frequency boost at the same power level. It also includes new AMD Infinity Cache technology that offers up to 2.4X greater bandwidth-per-watt compared to GDDR6-only AMD RDNA™-based architectural designs.
"Today’s announcement is the culmination of years of R&D focused on bringing the best of AMD Radeon graphics to the enthusiast and ultra-enthusiast gaming markets, and represents a major evolution in PC gaming,” said Scott Herkelman, corporate vice president and general manager, Graphics Business Unit at AMD. “The new AMD Radeon RX 6800, RX 6800 XT and RX 6900 XT graphics cards deliver world class 4K and 1440p performance in major AAA titles, new levels of immersion with breathtaking life-like visuals, and must-have features that provide the ultimate gaming experiences. I can’t wait for gamers to get these incredible new graphics cards in their hands.”
Powerhouse Performance, Vivid Visuals & Incredible Gaming Experiences
AMD Radeon™ RX 6000 Series graphics cards support high-bandwidth PCIe® 4.0 technology and features 16GB of GDDR6 memory to power the most demanding 4K workloads today and in the future. Key features and capabilities include:
AMD Infinity Cache – A high-performance, last-level data cache suitable for 4K and 1440p gaming with the highest level of detail enabled. 128 MB of on-die cache dramatically reduces latency and power consumption, delivering higher overall gaming performance than traditional architectural designs. AMD Smart Access Memory – An exclusive feature of systems with AMD Ryzen™ 5000 Series processors, AMD B550 and X570 motherboards and Radeon™ RX 6000 Series graphics cards. It gives AMD Ryzen™ processors greater access to the high-speed GDDR6 graphics memory, accelerating CPU processing and providing up to a 13-percent performance increase on a AMD Radeon™ RX 6800 XT graphics card in Forza Horizon 4 at 4K when combined with the new Rage Mode one-click overclocking setting. Built for Standard Chassis – With a length of 267mm and 2x8 standard 8-pin power connectors, and designed to operate with existing enthusiast-class 650W-750W power supplies, gamers can easily upgrade their existing large to small form factor PCs without additional cost.
True to Life, High-Fidelity Visuals
DirectX® 12 Ultimate Support – Provides a powerful blend of raytracing, compute, and rasterized effects, such as DirectX® Raytracing (DXR) and Variable Rate Shading, to elevate games to a new level of realism. DirectX® Raytracing (DXR) – Adding a high performance, fixed-function Ray Accelerator engine to each compute unit, AMD RDNA™ 2-based graphics cards are optimized to deliver real-time lighting, shadow and reflection realism with DXR. When paired with AMD FidelityFX, which enables hybrid rendering, developers can combine rasterized and ray-traced effects to ensure an optimal combination of image quality and performance. AMD FidelityFX – An open-source toolkit for game developers available on AMD GPUOpen. It features a collection of lighting, shadow and reflection effects that make it easier for developers to add high-quality post-process effects that make games look beautiful while offering the optimal balance of visual fidelity and performance. Variable Rate Shading (VRS) – Dynamically reduces the shading rate for different areas of a frame that do not require a high level of visual detail, delivering higher levels of overall performance with little to no perceptible change in image quality.
Elevated Gaming Experience
Microsoft® DirectStorage Support – Future support for the DirectStorage API enables lightning-fast load times and high-quality textures by eliminating storage API-related bottlenecks and limiting CPU involvement. Radeon™ Software Performance Tuning Presets – Simple one-click presets in Radeon™ Software help gamers easily extract the most from their graphics card. The presets include the new Rage Mode stable over clocking setting that takes advantage of extra available headroom to deliver higher gaming performance. Radeon™ Anti-Lag – Significantly decreases input-to-display response times and offers a competitive edge in gameplay.
