Radeon GPUs Rumor Mill

As the RDNA 4 rollout cycle comes to an end, rumors about the next generation of Radeon GPUs are heating up. According to @Kepler_L2 on X, a reliable leaker, AMD is reportedly equipping its upcoming UDNA-based GPUs with the HDMI 2.2 display protocol. This new protocol is capable of supporting bandwidths of 64 and 80 Gbit/s, with the highest-end bandwidth of 96 Gbit/s (Ultra96) expected in the next generation. The HDMI Forum officially released the HDMI 2.2 specifications in January during CES, with HDMI 2.2 cables expected to hit shelves in Q3 or Q4 of 2025.

However, AMD's next-generation GPUs will not fully utilize all the features of the HDMI 2.2 update in the upcoming GFX13 GPU architecture.

The HDMI 2.2 update introduces a Fixed Rate Link architecture that provides up to 96 Gbps of bandwidth. This enables uncompressed 4K at 240 Hz or 8K at 60 Hz with full 4:4:4 chroma, and sets the stage for even higher resolutions like 10K and 12K at 120 Hz. It supports both uncompressed and visually lossless compressed formats, as well as advanced chroma sampling options. This increased data throughput caters to the demands of immersive audiovisual experiences in next-generation gaming, augmented and virtual reality, professional displays, medical imaging, and machine-vision systems.

The Ultra96 HDMI cable is designed to handle all HDMI 2.2 features and is accompanied by the new Latency Indication Protocol, ensuring precise lip-sync and audio-video alignment across complex setups involving receivers, soundbars, and other devices.
