AMD Radeon RX 7000: New reference to Displayport 2.0 with up to 80 GBit/s

After there were indications last year that AMD’s Linux driver would support Displayport 2.0 in AMD’s upcoming Radeon RX 7000 series, the VESA standard for the monitor connection, which was specified in 2019, is again in patches for the open source drivers been sighted, with the Discovery in program code was initially shared by Twitter user @Kepler_L2.

Accordingly, the improved display port connection in AMD’s next series of graphics cards based on the RDNA 3 architecture will also receive UHBR certification (Ultra High Bit Rate), specifically supporting the UHBR20 mode. The different UHBR modes, such as HBR10, UHBR13.5 or UHBR20, quantify the maximum connection throughput, whereby the corresponding speed must be supported by the source and receiving devices.

UHBR20 offers a bandwidth of up to 80 Gbps, which is 32 Gbps more than HDMI 2.1 standard and 48 Gbps more than DisplayPort 1.4a. Noisy Videocardz.com theoretically, this standard would allow the output of 16K resolution with Display Stream Compression, 10K resolution without compression, or two 8K HDR displays at 120 Hertz.

As the report further notes, the adoption of Displayport 2.0 monitors has been repeatedly delayed. In January last year, the spec’s VESA confirmed that corresponding products should be released by the end of 2021, which was not the case, but with the Radeon RX 7000 series expected later this year, that could change.
