AMD RDNA3 GPUs would possibly strengthen UHBR20, permitting DisplayPort bandwidth as much as 80 Gbps

What simply came about? A up to date AMD show engine drivers patch added strengthen for Displayport 2.0’s Extremely Top Bit Price (UHBR) transmission modes. The function will permit a most bandwidth of 80 Gbit/s, which, coupled with DSC, will have to be sufficient for many presentations introduced in the following couple of years.

Even if we’re nonetheless a couple of months clear of the release of AMD’s next-gen GPUs, the corporate is tricky at paintings creating the device that may make the ones playing cards paintings correctly.

A up to date patch confirms that GPUs in accordance with the RDNA3 structure will strengthen DisplayPort 2.0 and would possibly be capable to the very best UHBR20 transmission mode. If used with a succesful cable and track, that might permit for a most bandwidth of 80 Gbit/s.

In March, the Video Electronics Requirements Affiliation (VESA) began its DP 2.0 certification program. There are already a few cables which can be UHBR20 qualified, even if they are restricted to 0.8m. As DP 2.0 leverages the Thunderbolt 3 bodily interface layer, passive cables percentage the similar period barriers when the use of the very best switch speeds. This downside will also be solved with costlier energetic cabling.

If AMD’s upcoming GPUs strengthen UHBR20, they will have to be capable of output HDR video with a solution of 4K at 240 Hz or 8K at 60Hz with out even the use of DSC. With DSC, which VESA claims is visually lossless and will compress an information move by means of a three:1 ratio, you have to pressure an 8K 144Hz HDR display via a unmarried cable.

In fact, there is additionally the problem of no longer having any DP 2.0-capable screens. Those were given behind schedule a number of instances, however they are confidently going to release quickly, taking into consideration we nearly have host units supporting the usual available on the market.
