What’s New With AMD GPUs? Early Signs of HDMI 2.2 Compatibility
Fresh rumors have surfaced regarding AMD’s next-generation GPU architecture , hinting that the company may be preparing support for the latest HDMI 2.2 standard , potentially offering up to 80Gbps bandwidth .
According to reports, this upgrade is expected to apply to AMD’s upcoming graphics architecture — internally referred to as GFX13 — which is rumored to launch under either the RDNA 5 or UDNA branding in the near future.
The latest details come from well-known leaker @Kepler_L2 , who shared new insights on X (formerly Twitter) via VideoCardz . The leak adds more credibility to earlier speculation that next-gen AMD GPUs will include improved display connectivity , aligning them more closely with the evolving needs of modern gaming and high-resolution content creation.
🔌 What Is HDMI 2.2 and Why It Matters
The HDMI 2.2 standard was officially announced earlier this year and made available to manufacturers in early 2025. Among its key upgrades:
- Maximum bandwidth increased to 96Gbps
- Introduction of the Latency Indication Protocol (LIP) , which improves synchronization between audio and video streams
- Better support for high-refresh-rate 4K and 8K displays
However, based on Kepler’s findings, AMD’s RDNA 5 GPUs are likely to support only the 64Gbps and 80Gbps modes , meaning full compatibility with the 96Gbps mode may not be available at launch. Whether this is due to hardware limitations or a decision to enable it later through firmware remains unclear.
💼 Consumer vs. Professional Lineup: Will There Be a Difference?
The leak doesn’t specify whether these HDMI 2.2 capabilities will apply to both consumer and professional lines — such as the Radeon RX and PRO series , respectively.
In the past, AMD has differentiated between product lines by using UHBR 13.5 (54Gbps) for consumer cards to keep costs down, while reserving UHBR 20 (80Gbps) for PRO models. Whether AMD continues this approach with GFX13 remains to be seen.
🖥️ What About DisplayPort 2.1b?
Alongside HDMI 2.2, another major update making waves this year is DisplayPort 2.1b , which also supports 80Gbps bandwidth but introduces improved cable compatibility . Specifically, it allows for three times the length of UHBR20 cables compared to current VESA-certified DP80 passive cables.
This updated standard is already confirmed to be supported on NVIDIA’s RTX 50 and RTX PRO Blackwell series GPUs , raising questions about whether AMD will follow suit.
So far, there has been no official word on whether DisplayPort 2.1b will be included in the GFX13 architecture , but many eyes are now watching for confirmation as the launch date draws closer.
🧩 Final Thoughts
While nothing has been officially confirmed by AMD yet, the growing number of leaks and technical references suggests that the company is indeed working on significant improvements to display output features in its next-generation GPUs.
If true, supporting HDMI 2.2 with 80Gbps bandwidth would place AMD back in the conversation with NVIDIA and help meet rising demand for higher resolutions, smoother refresh rates, and lower latency — especially among gamers and creative professionals.
Stay tuned for more updates as we get closer to the anticipated release of AMD’s next-gen graphics lineup.
