AMD To Feature HDMI 2.2 64 Gbps & 80 Gbps Display Functionality on Next-Gen Radeon GPUs

AMD’s next-generation Radeon GPUs, based on the GFX13 IP, will utilize the latest HDMI 2.2 display standards, offering up to 80 Gbps bandwidth.

HDMI 2.2 With Up To 80 Gbps Display Bandwidth Is Headed To Next-Gen AMD Radeon GPUs, Likely The UDNA-based Lineup

AMD’s next-generation Radeon GPUs, based on the GFX13 architecture, have already been spotted in Linux databases. While the launch is still a year away, we are getting more and more information regarding the Red Team’s upcoming GPU architecture, which will transition into the UDNA series.

Based on new information from Kepler_L2, it looks like AMD’s next-generation GPUs will come with updated display capabilities in the form of HDMI 2.2. The insider states that the new Radeon GPUs will come with HDMI 2.2 64 Gbps & 80 Gbps support, which will be an upgrade over HDMI 2.1 that’s featured on RDNA 4 GPUs. The HDMI 2.1b specification goes up to 48 Gbps, whereas HDMI 2.2 goes up to 96 Gbps.

As for the DisplayPort specifications, Kepler doesn’t point out specifically to the ones used by the next-gen Radeon GPUs but does mention that existing architectures support DisplayPort 2.1 with the UHBR20 specification for the PRO series and the UHBR13.5 specification for the consumer series due to cost constraints. NVIDIA supports DP2.1b with UHBR20 specification & HDMI 2.1b.

As for what HDMI 2.2 specifications have on offer to consumers:

Next-Gen Fixed Rate Link (FRL) – Future-Forward Benefits

• Enables higher quality options now and in the future for content producers such as TV, movie, and game studios, while enabling multiple distribution platforms
• Gaming and VR/AR payload bandwidth doubles every 2–3 years, leveraging uncompressed 4K / 240Hz at 10-bit and 12-bit, and beyond.

More Options – More Formats

• The HDMI 2.2 Specification delivers enhanced options for the vast HDMI ecosystem, with more advanced solutions to create, distribute, and experience the best end-user outcome.
• Supports multiple opportunities, along with options for uncompressed and compressed video and chroma sampling

Multiple Resolutions and Refresh Rates
Compression and chroma sampling enable higher resolutions and refresh rates, including:

• 4K@480
• 5K@240
• 8K@240
• 10K@120
• 12k@120
• Uncompressed full chroma formats include, for example, 8K60/4:4:4 and 4K240/4:4:4 at 10-bit and 12-bit.

Once again, AMD’s next-gen UDNA-based Radeon lineup with the GFX13 architecture isn’t landing before 2026, so there’s still a lot of time left before we get more concrete information on the GPUs and the respective lineup.
