Not how it is implemented by Intel. Not at all.
Anybody read my thread on this? (Details on exact level of support of USB4 ports on 13th gen? - #6 by Ray519)
a) Intel specs their USB4 ports from 13th gen mobile as capable of DP UHBR10 & UHBR20 and USB3 20G (for completeness sake: only natively on the port, not tunneled. DP UHBR would not even fit). But they also say that this requires Hayden Bridge ReTimers and not the same Burnside Bridge ReTimers that were used on the 11th and 12th gen FW mainboards.
FW has not published the mainboard specs for 13th gen on Github, only AMD, 11th and 12th. So we cannot read from there which ReTimers are used. FW has no specific specs for USB-C ports that say it supports USB3 20G or anything more than the 12th gen.
So, check what ReTimers you have. I have found no Intel 13th gen notebook advertising USB3 20G support (or DP UHBRx support). You’d be the first to show that support. If you do not have them, USB3 20G is not supported.
b) the spec version, as always does not guarantee any speed. That is just a grave misunderstanding. It simply refers to a PDF that explains how one could implement USB3 20G. Seeing “USB 3.2” anywhere in NO WAY means USB3 20G speeds. That is why this spec version, just like the many other spec versions like DP 1.4, HDMI 2.1 should never be mentioned anywhere outside of referencing specific details, like quoting the exact wording inside a specific version of the spec PDF.
