One thing to stay up for: AMD has reportedly been engaged on its next-generation GPU structure for not less than two years. The brand new structure shall be known as UDNA, changing the RDNA title, and is anticipated 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 help 64 Gbps and 80 Gbps bandwidths over HDMI 2.2 connections. If the report is correct, it could 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.
HDMI2.2 64G and 80G 🧐

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