Just a few days after the official announcement Arc-branded independent gaming graphics processor As well as the name of the first-generation Xe-HPG (DG2) products, Intel has begun to reveal some basic technical details about these GPUs. It turns out that the new graphics chip will support DisplayPort 2.0 and ultra-high resolution displays with dark colors.
Intel this week Publish Some patches have laid the foundation for the “i915” kernel graphics driver to support DisplayPort 2.0, the report Fronix. Several patches specifically mentioned Display Port 2.0 UHBR [Ultra High Bit Rate] And 128b/132b channel encoding supports Intel’s DG2 series. A patch shows that the GPU will handle UHBR 20 mode that supports 80 Gbps raw bandwidth, which is a good indicator that at least some upcoming Arc’Alchemist’ GPUs will support DP 2.0 with UHBR 20.
DisplayPort 2.0 with UHBR 20 interface has an effective data rate of 77.37 Gbps and 128b/132b encoding, enabling higher resolution, higher refresh rate and wider color gamut display. A DP 2.0 cable will be able to drive a 30-bit (10-bit per color) 8K display at 60Hz HDR, without any type of compression (DSC or chroma subsampling). The same cable can support a 60Hz 24-bit 10K display, and HDR can be used without any compression. At the same time, through Display Stream Compression (DSC), a single DP 2.0 cable can support a 16K display with a resolution of up to 60Hz or a low-resolution display with a high refresh rate. For example, game players may now expect an 8K display with a 120Hz refresh rate.
VESA’s DisplayPort 2.0 specification was announced in mid-2019, so Intel’s support for GPU support for this technology is logical, and the technology will be available in the first quarter of 2022.
Interestingly, earlier this week AMD Released A Linux patch to enable DisplayPort 2.0 support on its future GPU based on the RDNA 3 architecture.
