At least on most ThinkPads, the AMD versions lack Thunderbolt 3/4/ USB 4.0 Full Feature (e.g. including TB) so if I have a Thunderbolt docking station, it will probably not work. Nobody confirmed to me, what would work in such a setting. Will Lenovo/ AMD provide USB 4 upgrade using firmware?
Of course, the next question is the potentially asymmetric RAM on the ThinkPads with one channel soldered and one SO-DIMM slot, e.g. the 48 GB version. Will it use dual-channel until ~32 GB and then single-channel? How will the GPU perform, e.g. will it use only one slot in such a configuration. So many questions...
Formally yes, but it isn't listed e.g. in the ThinkPad T14 Gen3 (AMD) specs as supported, they are all USB 3.2 only. No TB, no USB 4. TB 3 seems to be optional in the USB 4 spec, as it would need to support 40 Gbps speeds and not "only" 20 Gbps.
