guru3d USB4 2.0 fast enough for external graphics cards

In a recent announcement, the USB Forum revealed USB 4 Version 2.0. With 80Gbit/s, the new USB standard is twice as fast as the previous limit. According to the group, 80Gbit/s will also be supported via USB 4 Version 1.0 cables.

 

The latest version of the universal computer interface, USB4, receives an upgrade. The maximum data transmission rate with USB4 in version 2.0 will be quadrupled to 80 Gbit/s. The protocol improvements should also improve tunneling performance for USB 3.2, DisplayPort, and PCIe.

I wonder if USB will replace other types of video ports eventually.

One cable for video and power.

I'm so confused, and to be honest a little frustrated.  They need to be more consistent with USB protocols.  USB 1.0, 1.1, 2.0, and even 3.0 are all the same and backwards compatible.  Then we stepped into USB 3.1, USB C, USB 3.2 or something, and I'm sure this USB 4 stuff probably won't be universal either.  It's driving me batty.  USB, the U is supposed to stand for universal.

 

It's one thing to have different ends on the wires.  Or advancing the protocol, which I understand happens.  But things aren't backwards compatible at all anymore like they used to be.  If you have a USB 2.0 device for example, it sometimes does NOT work on a newer USB port anymore like it should.  And trying a USB 3.0 (or newer) device on an older plug....haha forget it.  Then there's large power draw differences that cause things to melt.  Just ugh. -_-

Sorry, not a big fan of USB anymore after blowing up 5 different USB hubs and still not having any luck because I have zero clue what the actual problems are.  It absolutely IS really neat though that they're getting 80Gbps though.  Should give display port, HDMI, and other types of cabling a run for their money, absolutely.  One cable that does 4k display, keyboard, mouse, LAN, etc, etc.  I believe Linus uses something similar, Thunderbolt was it?

 

The advancement is cool.  I just wish they'd be more universal since that's quite literally a part of the name.

That's a confusing name. So its USB 4 2.0.

They should just give up on the naming.  It's all USB C anyway.
