AMD´s next-gen UDNA Radeon GPUs to support HDMI 2.2 at up to 80 Gbit/s

As AMD wraps up its RDNA 4 launch cycle, anticipation is building around its forthcoming UDNA-based Radeon GPUs, fueled further by recent leaks from well-regarded source @Kepler_L2 on X. The new graphics cards are set to support the recently announced HDMI 2.2 standard, leveraging bandwidths of 64 and 80 Gbit/s. This hefty leap enables uncompressed high-refresh-rate 4K and 8K outputs, though the most advanced 96 Gbit/s Ultra96 bandwidth will remain out of reach until a subsequent GPU generation.

Formally introduced at CES this January by the HDMI Forum, HDMI 2.2 brings a future-oriented Fixed Rate Link architecture designed to meet the ballooning bandwidth needs of gaming, augmented and virtual reality, professional visualization, and machine vision applications. With official HDMI 2.2 cables scheduled for retail release in late 2025, the rollout dovetails with AMD´s planned GPU launches, though the initial deployment in the GFX13 architecture will not encompass the entire HDMI 2.2 feature set.

HDMI 2.2 offers support for uncompressed 4K at 240 Hz and 8K at 60 Hz at full 4:4:4 chroma, expanding the groundwork for even more ambitious resolutions like 10K and 12K at 120 Hz. The update is versatile, catering to both raw and visually lossless compressed signals, and includes sophisticated chroma sampling configurations. In addition, HDMI 2.2´s new Latency Indication Protocol ensures precise audio-video synchronization across intricate signal chains involving multi-device setups, enhancing professional and consumer experiences alike as data payload capabilities double steadily with each generation.
