A consortium of over 50 technology companies in China have united under the banner of the Shenzhen 8K UHD Video Industry Cooperation Alliance. They have unveiled a new connectivity standard called GPMI, which stands for General Purpose Media Interface. The goal is to support 8K display and reduce the number of cables used.
The GPMI standard consists of two subtypes – Type-C, which is compatible with the existing USB-C port, and Type-B, which offers higher performance but requires a new interface. GPMI Type-C supports a maximum data transfer bandwidth of 96 Gbps and a power of 240 watts, while GPMI Type-B supports a maximum data transfer bandwidth of 192 Gbps and a power of 480 watts. This surpasses USB4 version 2, which supports 80 Gbps, and Thunderbolt 4, which supports 40 Gbps.
Major companies in this consortium include Chinese TV manufacturers TCL, Hisense, and Skyworth. It is therefore likely that this new interface will initially be utilized for TVs in China.

TLDR: A group of Chinese tech companies have formed an alliance to introduce the GPMI standard for 8K display, offering higher bandwidth and power capabilities than existing USB and Thunderbolt alternatives. Major TV manufacturers in China are part of this alliance, hinting at the initial adoption of the new interface in the Chinese TV market.
