You are quoting an incorrect TDP number for the 338H (65W is not correct), and in addition to that you are misreading "maximum" as its minimum. It idles at far lower than 25W. And anyway, TDP is not a standardized number, it's not a real spec. Chip manufacturers are known for fudging those numbers.

I can see that you are depending on an outdated perception of Apple's competition, and I'm especially confused about what you're saying with displays. I would try comparing a more comparable laptop? I'm confused at why you're quoting a Dell without the display upgrade option, which only costs $150.

Lenovo X9 15p Aura Edition has a very nice OLED display. OLED displays consume more power than LCD, and yet it still beats MacBook Pro 14" M5 in battery life. See Just Josh Tech's video on this model for benchmarks and comparisons.

If it's not bright enough for you, great, there are other laptops with tandem OLED displays, like the ASUS ProArt P14.

I also think more generally it's easy to pick out a bad laptop that competes with Apple since there are so many models that compete against Apple instead of going through the effort to find which computers are the best-reviewed alternatives. Dell XPS 14 is not really at the top of Windows reviewers' rankings as an overall choice.

There is a lot of effort toward ARM in the Windows world, keep up with the times. The Qualcomm X2 Elite is another chip that's catching up with Apple's offerings, it's only lagging behind in graphics capability. It gets very similar performance and battery life otherwise, and Qualcomm laptops are frequently discounted.

Or maybe look at RTX Spark. Those computers definitely have nice displays as well, like the ASUS ProArt P14. That OLED panel has very similar specs to Apple's PROLED offering.
