AMD's next-gen RDNA 3 GPU architecture will debut later this year, with major testing going on right now: one of those tests involves the confirmation of the next-gen DisplayPort 2.0 standard on Radeon RX 7000 series graphics cards of the future.
In a new tweet discovered by "Kepler," we see that AMD has kicked off putting patches for DisplayPort 2.0 UHBR (Ultra-High-Bit-Rate) certification. DisplayPort 2.0 UHBR comes in UHBR10, UHBR13.5, and UHBR20 standards with varying bandwidth, resolution, and refresh rate support.
Why do we need DP2.0 UHBR20? Well, 16K at 60Hz (with DSC) is pretty damn impressive... the same goes for 10K @ 60Hz, and what will be my favorite: 4K @ 240Hz. All over a single cable.
AMD's new Radeon RX 7000 series GPUs should have DisplayPort 2.0 UHBR20, capable of 80Gbps of bandwidth: quite the upgrade over HDMI 2.1 which has 48Gbps of bandwidth, and DisplayPort 1.4a with 32.4Gbps of bandwidth. In the patches titled "DML changes for DCN32/321" we see that AMD is preparing for DisplayPort UHBR20 mode on its Radeon RX 7000 series GPUs.
