It's always a gamble with new laptops.

I've had multiple Thinkpad T-generations from T410 to the latest. Sometimes it does works flawlessly out of the factory at purchase.

This time, it did not. The 12th gen Intel CPUs have a heterogeneous design with traditional "P-cores" and low-power "E-cores". I'm suspecting the reason I see terrible performance is that the CPU scheduler does not handle this efficiently and assigns the wrong task to the E-cores.

Also the Intel WiFi does not even get detected. Have not dug deeper into that yet.

Anything > ~6(Intel) ~12(AMD/Realtek) months old tend to work smoothly out of the box, IME.
