> I would kill for a version of ThinkPad X1 Nano or X1 Carbon for example that had the battery life, silence, and unplugged performance of a Macbook Air

Ditto on the Nano. I wind up looking at it every few months and then begrudgingly walking away because it just doesn't make any sense to buy.

I have the first gen and it’s about the perfect size for an ultraportable in my opinion, and its screen, build, and general feel are great but its battery and CPU are underwhelming at best.

The newer gens are even more confusing because they don’t offer the cooler, more efficient U CPU variants, only the hotter more power hungry P variants, which exacerbates heat and battery life issues.

U chips are just P chips with a tighter power limit, they’re not inherently “more efficient” (same architecture), just a lower cap.

is there really anything stopping you from setting a lower cTDP if that’s really what you want?

[jwells89]

Where would you set that? The only PC I’ve seen that lets you explicitly set a target TDP is the Steam Deck, the most I’ve seen elsewhere is the ability to turn off turboboost and limit clock speed.

Regardless, a default TDP above that of a U chip in a Nano is still an odd choice given that machine’s lack of cooling and battery capacity resulting from its size. It means that a lot of buyers who have no idea how to reduce it are going to have a subpar experience.
