Title: China Launches GPMI, a Powerful Alternative To HDMI and DisplayPort

AmiMoJo writes: The Shenzhen 8K UHD Video Industry Cooperation Alliance, a
group made up of more than 50 Chinese companies, just released a new wired
media communication standard called the General Purpose Media Interface or
GPMI. This standard was developed to support 8K and reduce the number of
cables required to stream data and power from one device to another.
According to HKEPC, the GPMI cable comes in two flavors -- a Type-B that
seems to have a proprietary connector and a Type-C that is compatible with
the USB-C standard. Because 8K has four times the number of pixels of 4K and
16 times more pixels than 1080p resolution, it means that GPMI is built to
carry a lot more data than other current standards. There are other variables
that can impact required bandwidth, of course, such as color depth and
refresh rate. The GPMI Type-C connector is set to have a maximum bandwidth of
96 Gbps and deliver 240 watts of power. This is more than double the 40 Gbps
data limit of USB4 and Thunderbolt 4, allowing you to transmit more data on
the cable. However, it has the same power limit as that of the latest USB
Type-C connector using the Extended Power Range (EPR) standard. GPMI Type-B
beats all other cables, though, with its maximum bandwidth of 192 Gbps and
power delivery of up to 480 watts.
