GPMI connector promises 192Gbps bandwidth and 480W power via a single cable

A new connection standard might be on the horizon. Developed by a consortium of Chinese companies, General Purpose Media Interface (GPMI) leverages USB Type-C and USB Type-B connectors to deliver high bandwidth for next-generation displays and integrated power delivery.

As reported by HKEPC (via VideoCardz), GPMI is positioned as a future-proof, all-encompassing technology designed to supersede existing audio and video interfaces. The standard's core emphasis is on providing a comprehensive solution, integrating power delivery within the cable to address power supply limitations. However, GPMI's capabilities extend beyond power, encompassing data transfer, fast wake-up functionality, bidirectional connections, and other features.

The standard is targeted at a wide range of applications, spanning consumer electronics, radio and television broadcasting, smart homes, security monitoring systems, automotive systems, and industrial equipment. Notably, the initial focus appears to be on the consumer electronics sector.

The USB Type-C implementation offers up to 96 Gbps, surpassing the latest DisplayPort 2.1 standard's bandwidth while supporting up to 240W of power delivery. The USB Type-B variant significantly expands these limits, doubling bandwidth and power capacity to 192 Gbps and 480W, respectively. The standard's bidirectional nature allows simultaneous data transfer alongside audio and video transmission. For example, a set-top box, typically relying on WiFi for network connectivity and HDMI for audio/video output, could potentially use GPMI for network data reception and display output, eliminating the need for separate connections.

GPMI is being championed by the Shenzhen 8K Ultra High Definition Video Industry Collaboration Alliance, which comprises over 50 companies, including TCL, Hisense, and Huawei. Moreover, the Type-C variant has already obtained the approval of the USB Association, meaning we might see devices using the standard very soon.
