The big problem with newer AMD ThinkPads from what I've heard is use of some second-rate (mostly Realtek) components in places, which in comparison to those used on Intel models don't perform as well and are more likely to cause trouble under Linux.
Actually they use four different. You can swap them yourself (15 - 20 EUR):
* Qualcomm (Atheros) -> GOOD (or even best?)
* Intel -> GOOD
* Realtek -> It works okay for average users
* MediaTek -> Bad or lack of reputation
The X13 is currently shipped with Qualcomm.
Older T14 seem to use mostly Intel.
On a P14 Lenovo we got a MediaTek (no reliable after Resume from Suspend) replaced by Realtek.
I would be happy if AMD and Qualcomm team up together again. The questionable ARM-Deal with Microsoft also didn't worked out well for Qualcomm.
