- China’s GPMI cable could finally replace HDMI and Thunderbolt
- GPMI supports 16k video, high power and universal control
- GPMI offers more speed and power than HDMI ever could
After his push to replace Bluetooth with nearby link, China is now turning attention to physical connectors targeting HDMI, USB4 and Thunderbolt with a new alternative with high bandwidth.
The General Purpose Media Interface (GPMI) was recently revealed by Shenzhen 8K UHD Video Industry Cooperation Alliance, a consortium of over 50 tech companies.
GPMI is designed to meet the requirements for Ultrahøj Resolution Content and promises significant improvements in speed, power supply and versatility, enough to transmit 8K and potentially even 16K, video.
A choice of versions
The GPMI standard comes in two versions-the more powerful GPMI Type-B offers a massive bandwidth from 192 Gbps and can deliver up to 480 watts of power, enough to support high-performance laptops for photo editing and far exceed the capacity of HDMI or Thunderbolt.
The GPMI Type-C, on the other hand, uses the widely adopted USB-C form factor, but doubles the bandwidth of USB4 and Thunderbolt 4 and reaches 96 Gbps.
It also matches the USB4S 240-watt power supply, enough to operate 5K/8K screens and charging devices simultaneously.
In comparison, HDMI 2.1 maximizes 48 Gbps and provides no power. USB4 and Thunderbolt 4 both top on 40 Gbps with power supply of 240W and 100W respectively. DisplayPort 2.1, currently leading in bandwidth of 80 Gbps, does not offer power transmission.
In addition, the GPMI standard supports a universal remote control protocol that allows users to control multiple connected devices with a single remote control.
This will be especially useful for creative professionals who depend on multiple screens or peripheral devices, such as those who use advanced laptops for graphic design.
