New 480W and 192Gbps GPMI format signals China’s broader move beyond USB-C and western cable standards

[Redaktion]

China's tech industry is pushing a new cable format called GPMI, built to handle video, power, and data at once. Reports state that the Type-B format will offer up to 480W charging and 192Gbps bandwidth.

Sounds pretty impressive, and single unified cable for everything would be awesome. Will the West get behind it? Is it an open standard with no licensing fee required unlike TB?

Well as of USB4, TB is actually open. Just if you want to use thunderbolt logo and be certified you have to pay intel. Otherwise, if you don't care about calling it thunderbolt and the certification, anyone can make a thunderbolt device/cable.

It is not about USB replacing standard or evolution of usb cables.

Its just for TV makers that want to stop paying the HDMI licensing standard.
There is no way this cable will ever replace USB-c Standard due to the size of it ..

Im very surprised OP doesnt understand properly licensing / open source and constalty provide misleading information .

GPMI is a try to replace HDMI standard . thats all . nothing more nothing else.

If they wanted to do that, there is DisplayPort, the TV companies intentionally chose HDMI because it is proprietary and locked down compared to the open standard DisplayPort

And best of all, these days DisplayPort can be sent over standard USB-C!

I don't think it's about that entirely either. You could make a couple of easy arguments, that Chinese companies don't want to be at the behest of Western standards, and that it might be that the Chinese government (or even just the companies for their own reasons) want to dictate the standard, considering they produce an outsize amount of the total electronics using these standards, they could definitely be thinking that this could give them that.

Which if that's the goal, I think this is a relatively smart way to do it (leverage pre-existing standard in USB-C USB4/TB4/5), making it easy to adopt and the convenience that it will enable over HDMI, especially with streaming sticks and other that need separate USB power. Personally I'd love if monitors and TVs would add USB-C (some portable displays and projectors already do, but I'd like it to be ubiquitous). I actually wish it had even been part of the USB-C mandate that Europe pushed, as it would help reduce waste and absolutely improve things for consumers. I've also had better luck with USB-C cables than HDMI.

Which, the simple fact that even the base version leverages USB-C while offering higher throughput than even DP2 is impressive. Granted we already know it's possible since TB5 can do even more than that (120Gbps), and if it was just one direction it seemingly could offer as much as 160Gbps (since TB is bi directional so it could do 80Gbps both ways, or optionally 120/40). Without knowing compression or other facets, tough to say if it would be better in absolute than just TB5 and DP over it.

I will say, I think they're actually making a bad decisions to make a separate new connector that seems to just be doubling it, instead of just offering the ability to use 2 cables to get that. I feel the same about USB/TB, they need to find a way to duplex it (which maybe Apple does? but most of the PCs that feature more than one TB port are effectively limited to the overall throughput of what a single one would be capable of because it features just one controller so it'd get shared).

But then I do think it would be possible to improve USB-C. I wish there was a mild "MagSafe" aspect integrated where just a small magnetic ring on the outer lip (basically where the plastic housing would be touching against the housing of the device its plugged into), to hold cables a bit, as I've encountered a fair amount of USB-C ports that are loose or become loose over time. Wouldn't need to be especially strong, just enough to make sure it stays seated. Maybe  I also personally would prefer a connector that is more similar to Lightning in that it is external only (meaning instead of the oval with the center piece that the metal portion of the USB-C connector surrounds in the port). With the MagSafe ring you could make it shallower so all cables effectively become MagSafe (in that if they get tripped/jerked it'll just come loose). Maybe they can make it electromagnetic, where if the device is powered off the cables are easily detachable, but would hold fairly strong when on, could be good for docks and other. Or be forward thinking and start making the move to fiber optic for data (not sure if fiber optic core with metal wiring around it, or metal core with fiber optic around it, or maybe multiple strands of both).
