AMD laptops cannot use the term "Thunderbolt" as it is owned by Intel and they do not want AMD to use it.

HP doesn't care: https://www.hp.com/us-en/shop/pdp/hp-omnibook-ultra-laptop-1... > 2 Thunderbolt™ 4 with USB Type-C® 40Gbps signaling rate (USB Power Delivery, DisplayPort™ 2.1, HP Sleep and Charge)[..] "Thunderbolt" is just a name like "USB". AMD didn't have Thunderbolt support because they'd need to license the technology from Intel, but that changed when Thunderbolt 4 was donated to USB.

good to know

TB4 supports DP2.0, which (in UHBR13.5 or UHBR20 mode) has enough bandwidth for 5K @ 120Hz (or 144/180 Hz with UHBR20). The issue is more likely to be availability, and marketability. In general the demand for high refresh rates on desktop displays is driven by gamers, far more so than resolution - it's pointless having a 5K or 6K display if your GPU can only render the game in a playable fashion at 1440P or whatever…

I used to subscribe to the "60Hz is enough for anyone" idea, but after using a high refresh rate monitor for a while, I have to admit it does feel a lot nicer to work with. Even small things, like window animations, feel a lot smoother by just a 50% increase in frame rate. Even Apple has upgraded their mobile displays to surpass 60Hz. With gaming monitors now doing ludicrous things like 1440p@480fps, I don't think 5k…

> I don't think 5k@120fps would even be difficult for manufacturers.

I didn't say it's difficult technically, I said it's about whether they think there is a market for this product.

You’ve been able to do that with Thunderbolt 4 for a while (with Display Stream Compression) - I currently drive an 8k ultrawide (7680x2160, or two 4K side-by-side) at 120 Hz off a single Thunderbolt 4 port.

What model?

Pretty sure he's talking about our Samsung Odyssey G9 57"

I too get 7680x2160x120Hz via TB4

Definitely not something to expect. AMD and Thunderbolt is not usually something you’ll see together. But you should be able to charge and do 5k with USB 4

Thunderbolt these days is nothing more than USB 4 with a few optional features made mandatory. Many AMD laptops support everything found in Thunderbolt but don't call it Thunderbolt for legal reasons.

Isn't that exactly backwards? "USB4 is TB with optional features ...?"

Phones now record 8k at 120Hz, so that thunderbolt bandwidth is important, else you will wait ages to transfer that to your computer.

Oh I'm with you on that. I think it was a great improvement to get Thunderbolt over USB-C on iPhone Pros. I just think it's a mistake to talk about the very latest Thunderbolt 5's bandwidth vs legacy Lightning as if Apple were still promoting it. It's like comparing Thunderbolt 5 to Firewire.

Apple are still promoting it

https://www.apple.com/uk/shop/buy-iphone/iphone-14/6.7-inch-...

Apple also argued against EU regulation forcing USB-C adoption by the end of 2024.

> It's like comparing Thunderbolt 5 to Firewire.

I don't think it's fair to make that comparison.

Given that we're only 10 days past the end of 2024, i don't think we would have iPhones with USB-C and 'non-legacy lightening' speeds like we do today.

Pretty much all new higher end AMD laptops have Thunderbolt, what are you talking about?

Thunderbolt has been royalty free and available to AMD since 2019.
