AMD Radeon RX 7000 series will support DisplayPort 2.0 UHBR20
At present, AMD is stepping up the software and hardware development of the RDNA 3 architecture GPU, making the final preparations for the Radeon RX 7000 series graphics cards to be released this year. Since the chip needs to be constantly tested, one can learn some information about the RDNA 3 architecture GPU from the information of AMD’s open-source driver.
Recently, Twitter user @Kepler_L2 found that AMD has started the UHBR (Ultra-High-Bit-Rate) certification of DisplayPort 2.0 and will support UHBR10 (40Gbps), UHBR13.5 (54Gbps), and UHBR20 (80Gbps). Among them, the highest specification UHBR20, its link rate is much higher than HDMI 2.1 (32Gbps) and DisplayPort 1.4a (48Gbps) currently seen on the market. Such a standard could theoretically enable a single 16K (15360 x 8460) display @60Hz / 30 bpp 4:4:4 HDR (DSC), or a single 10K (10240 x 4320) display @60Hz / 24 bpp 4:4:4 ( uncompressed) output standard.
The Video Electronics Standards Association (VESA) introduced UHBR to the DisplayPort 2.0 specification in 2019, however, due to the impact of the COVID-19 epidemic, the formulation of the entire DisplayPort 2.0 standard and the development of related products have not been smooth. The Video Electronics Standards Association confirmed in January last year that DisplayPort 2.0-compliant products would appear by the end of 2021, but it hasn’t actually been seen until now.
Intel is the first to support DisplayPort 2.0 on the Alchemist (DG2) discrete graphics card of the Intel Arc brand with the Xe-HPG architecture. AMD also confirmed at Computex 2022 that motherboards equipped with 600 series chipsets can also provide DisplayPort 2.0 interfaces. It is expected that the GeForce RTX 40 series and Radeon RX 7000 series GPUs released this year will use the DisplayPort 2.0 interface, and we are currently waiting for the appearance of related devices.
