My System Specs

Default VESA talks DisplayPort 2.0

3x the bandwidth of 1.4a and fully backwards compatible. no word on release date though...

This is great in that you will be able to drive 4K 144hz + without issue or maybe some wide variant of it.

Also interesting that its using the TB3 Phy... Maybe this is why Intel decided to release it as open/royalty free for USB4 (or vice versa). Its going to be so ubiquitous . Lets hope they fix Intels self imposed issues with it (forced BW reservation) ;)

My fear is just how long it is going to take for things like this to end up on cards.

I take some of that back, after reading Anandtech. Tethered connections are stupid and this is a non-starter for most.

how come? for multi-monitor display setups, it has a undeniable level of convenience.

Having a non-replaceable manufacture determined fixed length cord for every device limits the ability to use different lengths to fit your needs as well if something breaks or a cable/connector goes bad throwing out a 700$ monitor is CRAZY

Honestly at this point I'm all for them killing off HDMI & DisplayPort for USB-C to handle video. 4 USB-C connectors could almost fit in the space of 1 regular sized display port connection, less space taken allows for better venting on an air cooled card. Daisy chaining USB-C monitors is a huge convenience on multi monitor setups etc.

oooh, you meant tethered as in wired directly in. agreed, that's a terrible idea.

Displayport 1.4 is ~32Gbps*
Displayport 2.0 is ~80Gbps*
HDMI 2.1 is ~48 Gbps*
USB 3.2 Gen 2x2 is ~20Gbps*
Thunderbolt 3 is ~40Gbps*
USB 4 is ~40Gbps*

*Effective rates are lower

2560x1440 @ 120hz @ 8 bit = 13.27Gbps
3840x2160 @ 120hz @ 8 bit = 35.64 Gbps
3840x2160 @ 120hz @ 10bit = 44.55 Gbps

Keep in mind 10-bit is required for true HDR. As such, it's not feasible to completely replace DP or HDMI for GPUs.

Regarding packaging size - apparently Type-C connectors don't stack particularly well, as evidenced by the lack of them on motherboards, generally with that cited as the reason why. It'll be a problem on GPUs as well.

You make a good point about 120hz required throughput and wasn't something I was thinking of was thinking more form factor than anything.

USB-C doesn't need to be vertically stacked though for a GPU...
Radeon 6990 for reference... https://img.hexus.net/v2/TekSpek/AMD...radeon6900.jpg
4 mini display ports and a DVI didn't need any vertical stacking, and 4 USB-C connections would be even smaller than the 4 mini display ports.

Yes but you originally indicated 4x Type-C fitting in the space of 1x Displayport, but that could only be possible with stacking, something that isn't currently being done. It's likely 4x Type-C would allow for a 5th connector, similar to the 4x DP/1x DVI of the 6990.



This is of course assuming a reference size PCB, and not the egregious tall or "wide" cards that have come out in recent years.
