China Unveils GPMI: A Powerful All-in-One Cable for Video, Data, and Power

China has introduced a new media transmission technology that may transform how we connect our devices. Known as the General Purpose Media Interface (GPMI), this next-generation wired connection promises ultra-fast data speeds and high-power delivery—using just one cable.

What Is GPMI?

Developed by the Shenzhen 8K UHD Video Industry Cooperation Alliance, a consortium of over 50 Chinese tech firms including Huawei, TCL, and Hisense, GPMI merges video, audio, data, and power into a single connection. It’s designed to streamline modern setups by replacing multiple cords with one unified solution.

GPMI comes in two versions:

GPMI Type-B: Offers blazing speeds of up to 192Gbps and supports up to 480W of power—ideal for high-end video applications like 8K displays.
GPMI Type-C: Compatible with the existing USB-C ecosystem, delivering 96Gbps bandwidth and 240W power—more efficient than USB4 or Thunderbolt 4.

GPMI vs Existing Cable Standards

Here’s how GPMI stacks up against today’s leading media interfaces:

Interface	Max Bandwidth	Power Delivery
HDMI 2.1	48Gbps	None
DisplayPort 2.1	80Gbps	None
USB4/Thunderbolt 4	40Gbps	Up to 240W
GPMI Type-B	192Gbps	Up to 480W

With these specs, GPMI Type-B more than doubles the bandwidth of DisplayPort 2.1, while also offering high-wattage power—something neither HDMI nor DisplayPort provides.

How GPMI Benefits Gamers and Viewers

For Gamers

8K Gaming Ready: GPMI Type-B can support ultra-high resolution gaming with high frame rates. While 480W may not be enough for heavy-duty multi-GPU desktop rigs, it’s more than capable for laptops and next-gen consoles.
Cleaner Setups: Gamers using laptops or portable systems will enjoy the simplicity of a single cable for display, power, and control—cutting down on desk clutter.

For Entertainment Systems

Smarter Connections: Instead of separate cords for video, power, and device syncing, one GPMI cable can do it all—ideal for TVs, streaming devices, and consoles.
Unified Control: Like HDMI-CEC, GPMI supports centralised device control, allowing users to manage multiple gadgets using just one remote.

A Glimpse Into the Future

Backed by Industry Leaders

With the support of China’s top electronics brands, GPMI could soon appear in a wide range of consumer products—from smart TVs to laptops—creating a unified ecosystem for data and power transfer.

Solving the Cable Mess

As homes fill up with smart devices, cable management becomes harder. GPMI provides a simple and elegant fix: one cable to handle everything.

Bridging Devices Across Brands

As more manufacturers adopt GPMI, it could drive better cross-brand compatibility. A single standard would mean fewer adapters, fewer cords, and fewer headaches for users.

What Might Hold It Back?

Despite its promise, GPMI faces a few hurdles:

Slow Rollout: Manufacturers will need time to redesign devices to support the new interface.
Connector Limitations: Type-B uses a proprietary design, which may delay widespread adoption outside China.
Power Constraints: Although 480W is substantial, it may fall short for the most power-hungry desktop systems.

The Bottom Line

GPMI could mark the next big leap in device connectivity. By combining ultra-fast data transfer, high-wattage power delivery, and control functionality into one cable, it has the potential to simplify setups across gaming, entertainment, and professional environments.

If global brands adopt it, GPMI might just become the new gold standard—replacing today’s cluttered cords with a single, smart connection.
