But they aren't doing that!*
They're specifically comparing performance between two similarly-priced laptops[1]. That's what "benchmark" means.
If this was a review between the two laptops I'd agree with you, but it isn't a review, it's a benchmark suite.

> Does it come with a screen with P3 color, 400 nits peak brightness, and HDR support?
> What is the battery size on both machines, and how long do each last?
> How thin is it? How light it it? How fast does it charge? How much does this affect you daily?
All of these are valid questions, just not for a benchmark. The benchmark is one set of inputs a potential purchaser would take into account, with the other inputs being all those things you mentioned.
[1] I assume that they're similarly priced - I skipped the introduction and went straight to the benchmarks.
