Microsoft Announces $299.99 Surface Thunderbolt 4 Dock That Connects via USB-C

USB-C carries many signals. Thunderbolt 4 is PCIe over USB-C. All Thunderbolt 4 is USB-C, but not all USB-C is Thunderbolt 4.
-
Thunderbolt is faster than USBC and has lower latency. This enables such peripherals as external PCI-E devices like high end graphics cards. It can also support multiple USB devices as well as Ethernet cards as a stack. It also used to be able to carry more power, but I am not sure if that is still true. Thunderbolt is a superior connection than USB, if your device supports it.

Thunderbolt is faster than USBC and has lower latency.
USB-C is a specification that describes a physical port, a port that is not specific to any one protocol. Thunderbolt is a protocol that has at least two physical ports specified for carrying it. Claiming Thunderbolt is faster than USB-C is a rather nonsense statement because to get the speed of Thunderbolt 4 it must use the USB-C physical port to carry the protocol. Thunderbolt also uses the mini-DP port but, unless there's been something new I am not aware of, the speed of the protocol would be limited by the capabilities of that physical port.
The USB spec used to have the physical ports and the protocol in the same specification documents, that is no longer true. They have one spec for the physical ports, and another for the protocol, and so confusingly USB ports don't always carry the USB protocol and the USB protocol isn't always carried on USB ports.
I know tone doesn't translate well over forums like this so don't think I'm trying to be mean, I simply want to correct a misconception on what USB-C means because I have a tendency to be a pedantic ass. Further, I have a tendency for misconceptions on USB to be a particularly sore spot for me for some reason.

Being a pedantic ass, almost got me kicked out of the place I live at. You have my support. Also, to my landlady, You don't have kids in someone (except if they are pregnant), You have kids with someone.

This is literally the best explanation I've read on the topic. Thank you for your pedantry.

Thunderbolt is PCIE. It can be carried over a USB-C connector.
-
Many governments have said mobile must use USB C. While most of us know that thunderbolt is just a fancy USB C port I suspect the real story here is that MS, like Apple, is being forced to end is high profit proprietary connector business.
-
It is not. Precisely zero government requirements relate to peripherals. Microsoft's Surface line has for a long time supported charging from a USB-C device since the Surface connector has from the very beginning been nothing more than USB-C and since their charging bricks have from the very beginning being USB-PD with a proprietary connector. Any Surface device with USB-C already supports charging meeting any government requirement.
Microsoft isn't forced to end it's proprietary connector business, it simpl

We are fortunate to be living in a time when USB is perfect, in it's final form, and that we'll never need another connector. Peak Technology, and it can now be mandated by law by politicians, the arbiters and brain trust of technology. No non compliant connectors, after all, there is no need for them./s Oh Frabjous day!
Meanwhile, people like myself would like to present our cable bins, full of all the other final configurations of USB and other cables.
-
The EU entities you're whining about rarely mandate anything other than "Industry must settle on a standard". They never say "They must use XYZ". They never say "That standard cannot be changed in the future". They just say "Hey, industry, pick a standard, and all abide by it, and if you change it, abide by that."
The EU has never mandated microUSB, USB-C, GSM, or any of the other technologies it's supposedly mandated.

https://www.consilium.europa.e... [europa.eu] It's a USB-C port that must be on phones sold in the European Union in 2024, and it is the law. That is a mandate.
You know, you could do a little research before declaring true statements as "whining". Not sayin'.. just sayin'.

USB-C (as referredf to in this article) is merely a physical plug interface.
The actual data transport is 4 pairs of differential TTL (same as SCSI, but differential SCSI uses 16 or 32 pairs of differential TTL operating at a much lower frequency, and direct keyed rather than encoded transport).
Then there are the various USB data encoding protocols which can be used to encode the binary data traversing the differential connections. These "encodings" are not in any way related to the "physical plug". You co

USB-C: It's a floor wax *and* desert topping!:)

For a comment that is pointing out that "the protocol isn't the connector" the above was a pretty big one to miss... RS-232 uses DB25 or DE9 connectors.:)

Not just an Apple thing. I recently got an Intel NUC (my new HTPC, yay!) which has it (but I'll probably just use its HDMI out).
I think it's a thing because it has more bandwidth than USB, but is somehow compatible with it, too. What I can't figure out is why Microsoft releasing docking station (and a surprisingly expensive one) is big news, except that I guess it further mainstreams Thunderbolt?

for vacations and the like (IE, would like to play games but don't want to pack up my desktop) i use a akitio node with a GTX 1080 gpu on a laptop with an anemic onboard gpu -- it actually performs quite, quite well.
something like 90% of the framerate you'd get running the card directly.something to consider for your NUC:)

USB/USB4 are protocols
USB-C is a port. it supports many different protocols over it - including things like HDMI and DisplayPort. It also supports 240W power delivery.
Thunderbolt 3.0 is one of the protocols supported over USB-C. It is basically PCIe over a wire.
USB4 is an incompatible protocol from USB 3.0, and is based on Thunderbolt 3.0. Yeah, the 4 isn't a version number but part of the name - USB4 2.0 is unfortunately a real thing.
Thunderbolt 4.0 is a brand, but it is by Intel. Think of it like AMD Free

No. No it is not. It's a whole different standard from the signalling upwards. It just happens to share a USB-C connector.
