- 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 could never
After its push to replace Bluetooth with Nearlink, China is now turning its attention to physical connectors, targeting HDMI, USB4 and Thunderbolt with a new alternative to the high band width.
The General Media Interface (GPMI) has recently been unveiled by the Shenzhen 8K UHD Video Industry Cooperation Alliance, a consortium of more than 50 technological companies.
Designed to meet the requests for ultra-high resolution content, GPMI promises significant improvements in speed, power delivery and versatility, enough to transmit 8K, and potentially even 16K, video.
A choice of versions
The GPMI standard is available in two versions – the most powerful GPMI Type -B offers a massive bandwidth of 192 Gbit
GPMI Type-C, on the other hand, uses the largely adopted USB-C shape factor but doubles the bandwidth of USB4 and Thunderbolt 4, reaching 96 Gbit / s.
It also corresponds to the power delivery of 240 Watts of the USB4, enough to supply monitors and load devices 5k / 8k simultaneously.
In comparison, HDMI 2.1 is maximum at 48 Gbit / s and does not provide any power. USB4 and Thunderbolt 4 are both at 40 Gbit / s, with a power delivery of 240 W and 100W, respectively. Displayport 2.1, currently the leader of the bandwidth at 80 Gbit / s, does not offer power transmission.
In addition, the GPMI standard supports a universal remote control protocol, allowing users to control several connected devices with a single remote control.
This will be particularly useful for creation professionals who count on several screens or peripherals, such as those who use high -end laptops for graphic design.
