New GPMI Cable Threatens HDMI Dominance
15 Jul
Summary
- GPMI, backed by 50+ Chinese firms, offers higher bandwidth and power delivery.
- HDMI 2.2 offers up to 96 Gbps, while GPMI reaches 192 Gbps.
- Major brands like LG, Samsung, and Sony have not yet supported GPMI.
A new contender, the General Purpose Media Interface (GPMI), is poised to challenge the established HDMI standard. This emerging connectivity protocol, developed by an alliance of over 50 Chinese technology companies including Hisense and TCL, aims to unify high-bandwidth audio, video, data, and power delivery into a single cable solution.
GPMI offers significant advancements over older standards, supporting higher resolutions and frame rates. Its two cable types, USB-C and a proprietary Type-B, provide impressive bandwidths of 96 Gbps and 192 Gbps, respectively. The Type-B variant also delivers up to 480 watts of power.
While HDMI 2.2 is now available with bandwidths up to 96 Gbps, GPMI's proprietary Type-B cable significantly surpasses this with its 192 Gbps capability and integrated power delivery. Despite GPMI's technical advantages, its widespread adoption faces hurdles, as major global brands like LG, Samsung, and Sony have not yet announced support. The market's transition to GPMI would require a significant industry-wide effort, while HDMI 2.2 already has a head start.
