Intel confirms that DG2 GPU will support DisplayPort 2.0
AMD just released a new Linux system graphics driver patch to prepare Radeon graphics cards to support DisplayPort 2.0 output. In view of the current RDNA 2 architecture GPU does not support DisplayPort 2.0 output, it is generally speculated that the new patch should be the preliminary work for the new generation of RDNA 3 architecture GPU.
AMD’s next-generation graphics cards are still some time away from consumers, but Intel’s first-generation Intel Arc products are already on the line. According to Phoronix reports, Intel has released a new Linux patch that has enabled DisplayPort 2.0 output for DG2 series GPUs. Unlike AMD’s patch, Intel’s patch notes have directly mentioned DG2 series GPUs, therefore, the first-generation Intel Arc graphics card code-named Alchemist supports DisplayPort 2.0 output. It should be the first consumer graphics card that supports DisplayPort 2.0 output.
Intel’s support for DisplayPort 2.0 started with 17 patches of the i915 kernel display driver, however, support for the DisplayPort 2.0 standard has not yet been fully realized, and engineers still have a lot of follow-up work to do. It is also mentioned in the patch that DG2 series GPUs support UHBR (Ultra High Bit Rate) as 128/132b channel encoding.
