There is plenty of hypothetical and conjecture in prior threads.
I guess it is possible we have all TB4 features available on the USB4 (2x) ports but without testing and certification, we would have to hear from the framework team on the capability/feature delta is between TB4 and USB4 (hopefully none).
As a user who primarily computes while docked (into a TB4 dock), it is important to me as a consumer. Thanks in advance for any official answer or detail.
Further details and documentation are also welcomed (such as USB-C output wattages), exact limitations of the lower expansion card slots, etc.
As @MJ1 wrote, Thunderbolt is a Trademark of Intel (and Apple). In reviewing the AMD Ryzen 7 7840HS spec sheet, this CPU supports 2 x USB4 ports. Which means you’d have 2 x 40Gb/s ports out of the 6 ports on the FW16. Note, that 40Gb/s with USB4 is only when using a 1M or shorter cable. When using a 1.5 or 2M cable, speeds are reduced to 20Gb/s. On the other hand, Thunderbolt 4 supports 40Gb/s up to 2M cable.
Otherwise, USB4 is “similar” to Thunderbolt but there are other differences. See this article which goes over the differences in detail. For most users, the big difference is Thunderbolt 4 can drive 2 x 4K monitors from a single port. USB4 can only do 1.
While it’s always nice to have official confirmation from FW, I’ll go out on a limb here (lol) and use the AMD specifications for the Ryzen 7 7840HS and pretty much confirm the USB 4 implementation in all AMD based FW laptops going forward will be full USB 4 40Gb/s. This means nearly all TB 4 features are included. I say nearly because there are some docks that may have a feature or two that won’t work the same when used in a solely USB 4 40Gb/s implementation. For example, dock based NICs, ability to use dual displays through dock are two potential hiccups that you should be aware of when dock shopping.
The poll here says they made the right choice. The community voted AMD over intel, and by a large margin. 80%
Framework does not have the resources of larger companies. They can’t provide every option all at once. Most people understand that more options will come in time, and that just impatiently complaining won’t help.
I don’t think it was so much a decision to go AMD only. I think it’s more a matter of limited resources and having to start somewhere. With the 13" they started with Intel and after a couple of years (while many said no AMD was a dealbreaker), they are finally releasing an AMD option. With the 16" they started with AMD. Hopefully an Intel option will be available in the future.
You make a good point. There’s no perfect solution. It’s a matter of tradeoffs and for the 16" it appears AMD rolled out the red carpet for FW and FW chose to take them up on it. Hopefully the AMD based FW16 is a winner.
I’m glad to see USB and Thunderbolt evolving. Maybe I’m getting older, but these protocols seem to be updated much sooner than I remember. I’d also like to see Oculink become a mainstream port for laptops and handheld gaming devices.
So that makes me wonder: Why does the AMD platform have less high-end/new protocols connectivity options? Is it because TB requires certification with Intel? If so, could Oculink be the answer?
I really hope to see open protocols to be standards and mainstream than proprietary ones, even if they aren’t the best. Ex: FSR vs DLSS, Freesync vs G-Sync, XMP vs EXPO, etc.
Well intel got a bit of a headstart there, they invented it together with apple and it still took 3 generations for it to become at least somewhat common outside apple products and is still missing on low to midrange intel stuff even if most of the previously expensive stuff now comes for free with the cpu (you still need the redrivers which aren’t cheap and and the certification but the barrier is a lot lower these days).
There is a lot of things people use thunderbolt for and occulink only really covers one (and even that with drawbacks and advantages).
Most of what people use thunderbolt for can actually be covered with just a simple usb3 + DP type-c port (dock with a bunch of usb ports and networking and a bunch of screens via mst and of course power). But the issue there is mostly that with a thunderbolt port you know what you are getting while with a random usb-c port it’s a bit luck of the draw depending on how the manufacturer felt that day.
For the egpu use-case where occulink shines it does definitely provide somewhere between more and a whole lot more bandwidth than tb4/usb4 (depending on if you got 4x or 8x) it does still have the drawback of not being hotpluggable which tb/usb4 is. This my be a dealbreaker for some. PCIE hotplug is possible but needs to be speciffically implemented on all levels.
Agree with you on most of those except the xmp/expo thing, those are just a set “know probably working settings” which are manufacturer specific by nature (the intel and the amd memory controller behave very differently). Better solution there would be to convince jdec to make spicier standard profiles XD.
