https://en.wikipedia.org/wiki/GPMI
A new wired media communication standard called General Purpose Media Interface (GPMI) has been introduced by the Shenzhen 8K UHD Video Industry Cooperation Alliance, comprising over 50 Chinese companies. This standard is designed to streamline connectivity for 8K devices by reducing the number of cables needed for both data and power transmission.
GPMI will come in two variations:
Type-B: Features a proprietary connector with a remarkable 192 Gbps maximum bandwidth and the ability to deliver up to 480 watts of power.
Type-C: Utilizes the standard USB-C connector and offers a maximum bandwidth of 96 Gbps with power delivery up to 240 watts.
The increased bandwidth of GPMI is crucial for handling the significantly larger data demands of 8K resolution, which has four times the pixels of 4K and sixteen times that of 1080p. While factors like color depth and refresh rate also influence bandwidth requirements, GPMI Type-C more than doubles the 40 Gbps limit of USB4 and Thunderbolt 4, while matching the 240W power delivery of the latest USB Type-C Extended Power Range (EPR) standard. GPMI Type-B surpasses all other listed standards in both bandwidth and power delivery.
The 480W power delivery of GPMI Type-B, while not sufficient for powering a high-end desktop gaming PC like one with an RTX 5090 through a monitor, offers significant potential for simplifying setups for high-end gaming laptops. Users could potentially use a single GPMI cable for both data transfer to an 8K display and power delivery to the laptop.
Furthermore, the GPMI standard will support a universal control protocol similar to HDMI-CEC. This would allow users to control multiple GPMI-connected devices, such as TVs and streaming boxes, with a single remote control, further simplifying home entertainment setups.
Currently, USB Type-C (via Alt DP/Alt HDMI) and Thunderbolt are the primary widely used video transmission standards that also offer power delivery, mainly for monitors. The widespread adoption of GPMI could revolutionize TV and streaming setups by enabling single-cable connectivity for both power and high-resolution media, promising a cleaner and more convenient user experience.
