AMD's next-gen Radeon GPUs rumored to support HDMI 2.2 with wider 80Gbps of bandwidth

AMD's next-generation Radeon GPUs based on the new UDNA (or RDNA 5) GPU architecture will support the upgraded HDMI 2.2 standard with 80Gbps of bandwidth according to the latest leaks.

In a new post on X by leaker @Kepler_L2, we're hearing that UDNA-based Radeon GPUs will support the new HDMI 2.2 standard with 80Gbps of bandwidth, upgraded from the HDMI 2.1 ports on current-gen Radeon GPUs that offer just 48Gbps of bandwidth in comparison.

AMD's next-gen Radeon GPUs will reportedly offer two different HDMI 2.2 modes with 64Gbps and 80Gbps, which is a big upgrade over HDMI 2.1 and its 48Gbps of bandwidth, but less than the 96Gbps ceiling of HDMI 2.2 in its full unleashed mode.

HDMI 2.2 was announced earlier this year at CES 2025 with some wicked high resolution and refresh rate support, with new HDMI 2.2-enabled products supporting 4K at up to 480Hz, 8K at up to 240Hz, and even 10K at up to 120Hz. HDMI 2.1 as it stands (and HDMI 2.1 cables) can only support up to 4K 120Hz, but for future TVs, monitors, graphics cards, and consoles, the ceiling is far higher than it is now (4x higher refresh out of 4K is impressive).

As for AMD's next-gen UDNA-based Radeon GPUs, the company will see Radeon "big core flagship" being back, with the new GPU being made on TSMC's N3E process node, which you can read more about in the links below.
