One thing to stay up for: AMD has reportedly been engaged on its next-generation GPU structure for at the least two years. The brand new structure will likely be known as UDNA, changing the RDNA identify, and is predicted to ship considerably sooner efficiency than RDNA 4. A tipster has now shared particulars concerning the rumored HDMI configuration of the first-generation UDNA GPUs.
In accordance with Kepler_L2, UDNA GPUs – codenamed GFX13 – will assist 64 Gbps and 80 Gbps bandwidths over HDMI 2.2 connections. If the report is correct, it will imply that AMD’s next-generation GPUs will not totally make the most of the potential of HDMI 2.2, which helps bandwidths of as much as 96 Gbps – additionally known as Ultra96.

GFX13 GPUs won’t assist Ultra96, regardless of adopting the HDMI 2.2 customary, as a result of they will not make the most of the Mounted Charge Hyperlink know-how that enhances the utmost knowledge switch fee to 96 Gbps. It is unclear why AMD has chosen to not supply Ultra96 connectivity with its next-gen graphics playing cards, however it may very well be a cost-saving measure.
In accordance with the HDMI Discussion board, the improved 96 Gbps bandwidth helps uncompressed video at extraordinarily excessive resolutions and refresh charges – resembling 4K at 480 Hz and 8K at 240 Hz with full 4:4:4 chroma sampling. It may possibly even deal with 10K and 12K video at as much as 120 Hz, probably making it a beneficial software for area of interest skilled use instances.
AMD is rumored to launch its UDNA graphics playing cards in 2026, focusing on each players and professionals. Reviews counsel that Sony’s PS6 can even use UDNA graphics, though it is unclear whether or not the CPU will likely be primarily based on Zen 4 or Zen 5 structure.
AMD confirmed final yr that it’s going to as soon as once more unify its gaming and knowledge middle GPU architectures, having cut up them into RDNA (for gaming) and CDNA (for knowledge facilities) in 2020. The corporate hopes that the mixed UDNA structure will make it simpler for builders to optimize GPUs for various use instances.
The HDMI 2.2 customary was formally printed by the HDMI Discussion board throughout CES 2025 in January. The brand new customary is backward appropriate with older HDMI connectors, so it can work with any current HDMI port.
Nevertheless, making the most of all the very best HDMI 2.2 options would require new Ultra96 Licensed cables. The most recent customary is prone to be included into new gadgets within the close to future, with appropriate cables anticipated to launch within the third or fourth quarter of this yr.
