Looks like the T14 Gen 7 is the first T14 to have a CAMM socket. The previous model has SODIMM DDR5-5600, more power hungry? Prior to that it was the more expensive P1 Gen 7 that had LPCAMM2.

Regarding the T14 and T16, I'm frustrated that in my market (AU), they don't sell better screens than 1920x1200. I'd like to have a brighter 3k or 4k screen.

The LPCAMM2 seems to be limited to the Intel models, according to the pc mag article.
