What Is GPMI? The Next-Generation High-Bandwidth Connector for TVs, PCs, and More

In April 2025, a new connectivity standard named General Purpose Media Interface (GPMI) was introduced by the Shenzhen 8K UHD Video Industry Cooperation Alliance, a consortium comprising over 50 Chinese technology companies, including Huawei, Hisense, and TCL . Designed to replace HDMI, DisplayPort, and Thunderbolt, GPMI aims to simplify multimedia connections by combining video, audio, data transmission, and power delivery into a single cable .

Understanding GPMI: A Technical Overview

GPMI is available in two types:

Type-C GPMI: Utilizes the existing USB-C connector, offering up to 96 Gbps bandwidth and 240W power delivery, aligning with the Extended Power Range (EPR) standard .

Type-B GPMI: Features a proprietary connector, supporting up to 192 Gbps bandwidth and 480W power delivery, surpassing current standards like HDMI 2.1 and Thunderbolt 4 .

These capabilities enable GPMI to handle ultra-high-definition video content, including 8K at 120 frames per second, and power demanding devices simultaneously .

Benefits of GPMI for Consumers

1. Simplified Connectivity

GPMI reduces the need for multiple cables by integrating video, audio, data, and power into a single connection. This simplification is particularly beneficial for home entertainment systems, gaming setups, and professional workstations, where multiple devices are interconnected.

2. Enhanced Performance

With support for high-bandwidth applications, GPMI facilitates smooth 8K video playback, high-fidelity audio transmission, and rapid data transfer, enhancing the overall multimedia experience.

3. Increased Power Delivery

The higher power delivery capabilities of GPMI, especially the Type-B variant, allow for powering devices that require more energy, such as gaming laptops and high-performance monitors, reducing the need for separate power cables.

Implications of GPMI for the Industry

1. Potential Disruption of Existing Standards

GPMI's introduction challenges established standards like HDMI, DisplayPort, and Thunderbolt. Its higher bandwidth and power delivery capabilities position it as a formidable alternative, potentially leading to a shift in industry preferences .

2. Adoption and Compatibility

While GPMI offers promising features, its adoption depends on support from major manufacturers and compatibility with existing devices. The Type-C variant's compatibility with USB-C ports facilitates easier integration, whereas the Type-B variant's proprietary connector may pose compatibility challenges .

3. Security Considerations

GPMI incorporates the ADCP content protection protocol, based on China's national cryptographic algorithms, to secure data transmission. This feature addresses concerns related to data security and privacy in multimedia communications .

Conclusion

GPMI represents a significant advancement in connectivity standards, offering enhanced performance and simplified connections for consumers and professionals alike. Its potential to replace existing standards could reshape the landscape of multimedia connectivity, provided it gains widespread adoption and support from the industry.
