Yes - but as this is a purpose-designed protocol for display transport over thunderbolt, I would expect it to perform better than a remote desktop solution intended to go over a potentially low-bandwidth network.

In the past I've found that using RDP to a VM running on localhost can actually perform better than the console provided by the VMM, but it's still not close to the experience of using the OS natively. I would expect this to be a lot closer.

Is it though? TB has native support for DisplayPort streams, but the article doesn't reference DisplayPort at all, and does make several other references:

> A decade ago, Intel showed off something very similar: a 10Gbit Ethernet-over-Thunderbolt demonstration called Thunderbolt Networking. This is a faster version, an Intel representative said via email. Thunderbolt Share uses up to a 20Gbps connection over Thunderbolt 4 with low latency

> Essentially, you’re performing a local, cabled version of Microsoft’s Remote Desktop without all of the setup.

I don't think there's any reason yet to believe that this isn't just a proprietary (or possibly even just embedded VNC) screen sharing solution that's tweaked for a high-bandwidth low latency connection.

macOS has a "high performance mode" for its regular screen sharing (as of v14, Sonoma) which works amazingly well even over wired Gigabit ethernet.

This was actually shown off at CES earlier this year, here's the only video I can find: https://www.youtube.com/watch?v=GqCwLjhb4YY

In this it's claimed that Intel is doing a direct framebuffer copy. I'd say the "Microsoft’s Remote Desktop without all of the setup." is editorialising.

It's not the clearest shot, but the latency shown at 30s in that video looks pretty good to my eyes.

On the other hand I've been caught out by tech companies making exaggerated claims about pre-release products before, so who knows, maybe it actually is no better than VNC.

Sounds like marketing speak for "vnc with an intel logo".
