AMD’s next generation graphics cards, the Radeon RX 7000, are expected to use Displayport 2.0 for the first time and could push the new connectivity forward.
After indications emerged last year that an AMD Linux driver would support Displayport 2.0 in AMD’s upcoming Radeon RX 7000 series, the VESA monitor connectivity standard, which was defined in 2019, is once again in patches for open source drivers that have been spotted, with Discovery in code first shared by Twitter user @Kepler_L2.
Accordingly, the next series of graphics cards from AMD based on the RDNA 3 architecture will also receive UHBR (Ultra High Bit Rate) certification, which specifically supports the UHBR20 mode. Various UHBR modes, such as HBR10, UHBR13.5, or UHBR20, define the maximum throughput of the connection, since the corresponding speed must be supported by the source and receivers.
The UHBR20 delivers up to 80Gbps bandwidth, 32Gbps more than the HDMI 2.1 standard and 48Gbps more than DisplayPort 1.4a. According to Videocardz.com, this standard will theoretically allow for 16K output with display streaming compression, 10K resolution without compression, or two 8K HDR displays at 120Hz.
As the report further notes, adoption of DisplayPort 2.0 monitors has been repeatedly delayed. In January last year, the spec’s VESA confirmed that corresponding products should be launched by the end of 2021, which it wasn’t, but with the Radeon RX 7000 series expected later this year, that could change.
