Bandwidth limitations. Power limits the amount of data, so use one for each, or double the data maybe?

Alright - why?
We know power and data can go over a single one.
It can’t be for more power - one should(?) be sufficient for whatever I’m looking at.
Only thing I can think of is some video optimization.

A single usbc can deviler 240W and data at 40 GB/s, what else can it be other than vendor lockin by nintendo?

What revision is that, and that’s also seriously limited by cord length.
It’s anything BUT, it’s a dev kit lmfao.

USB 3.2 or 4 allows for a thunderbolt 4 interface, that runs at 40 GB/s (for external gpu cards). Thunderbolt also uses Power Delivery and the latest version allows for a 48V @ 5A profile, that would be 240W. Even previous versions allow for 24V @ 5V (120W).
As for the cable length I wouldn’t really know, probably it’s possible up to a meter, if the cable is well shielded, the power doesn’t change much because the current os always rather low, it’s the voltage that increases.

I don’t know what it is really but I’d guess yo plug 2 things?
Very too close one tonthe other for me 😖

If it was to plug 2 things, the connectors would be separated so 2 plugs could fit into them.

More power, basically. Nintendo isn’t the only one that’s done this. Apple and dell both have laptops with them. superuser.com/…/why-do-some-docking-stations-have… has some other answers, such as video disabling certain functions.

This is a development kit, so the transmitted signals / pinout could have nothing in common with regular usb-c and they just needed more lanes than one usb-c cable can provide, leading them to develop this monstrosity.
Similar to the PCIe extenders that use USB3 male to male or HDMI as their connector / cable.

Can’t you do like 240w with USB C thunderbolt?
