AMD has announced its Radeon RX 6000 line of graphics cards, otherwise called Navi 21 or Big Navi. AMD CEO Dr. Lisa Su unveiled the three new GPUs — the Radeon RX 6800, 6800 XT, and 6900 XT. These are based on the brand’s 7nm RDNA2 architecture. The company claims the new cards compared to the previous Radeon 5700XT, deliver 2x performance, and 50% performance per watt improvement.
Here’s more on the specs and details —

Other highlights include:
- AMD Infinity Cache – 128MB of on-die cache for countering DRAM bottlenecks and ensuring latency.
- 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.
- 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 overclocking 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.
