A VirtualLink to the PastĪMD’s own versions of the Radeon RX 6000-series cards include USB-C across the board, which, for VR in particular, would allow the cards to support the VirtualLink standard-a USB-C ‘alt-mode’ which was designed to provide VR headsets with data, power, and video through a single port. While not a groundbreaking change in performance by itself, it’s essentially ‘free’ (if you have the right combination of hardware), and a smart way to leverage the company’s broader hardware portfolio. Called Smart Access Memory, the company says the feature allows the CPU to access more of the GPUs memory at once, resulting in a performance boost of a few percentage points depending upon the title. The company is also introducing a unique feature for users who pair AMD’s 6000-series GPUs with the company’s own 5000-series Ryzen CPUs. The card’s ray-tracing tech is based on the DirectX 12 Ultimate implementation AMD says developers can mix and match rasterization and ray-tracing effects, with “an order of magnitude” improvement in ray-tracing operations compared to the last generation of Radeon cards. The 6000-series cards also introduce hardware accelerated ray-tracing with one ‘Ray Accelerator’ per Compute Unit. Leveraging the best high frequency approaches from Zen architecture, AMD Infinity Cache enables scalable performance for the future,” the company explains. “This global cache is seen by the entire graphics core, capturing temporal re-use and enabling data to be accessed instantaneously. New to the 6000-series cards, ‘Infinity Cache’ is 128MB of memory directly on the GPU die. AMD says the cache acts as a “bandwidth amplifier” for the rest of the card’s memory 16GB of GDDR6 combined with the 128MB Infinity Cache increases “effective bandwidth” by up to 3.25 times compared to the same amount of memory without the cache. Infinity Cache, Ray-tracing, and Smart Access Memory And-better late than never-the RX 6000-series cards include a USB-C port to “power head-mounted displays with just one cable for a modern VR experience.”īefore we dive into details, here’s the release date, price, and basic specs of each card:ĭisplayPort 1.4 w/ DSC*, HDMI 2.2 w/ VRR*, USB-C*Ģx DisplayPort 1.4 w/ DSC, 1x HDMI 2.2 w/ VRR, 1x USB-Cīased on its new RDNA 2 architecture, AMD is positioning its 6000-series cards to compete directly with Nvida’s latest 30-series GPUs in price, performance, and features. With a release date in November and prices starting at $580, AMD is aiming to compete directly with NVIDIA’s latest 30-series GPUs. AMD today introduced the Radeon RX 6800, 6800 XT, and 6900 XT graphics cards based on its latest RDNA 2 architecture.
