Meteor Lake-U also only has 2 cores out of 10 (or 12 if you want to include those) that can do HT. Depending on how much the chips were turbo-ing, some of this could simply be due to higher sustained clock speeds.

Also, hyperthreading is just supposed to fill the gaps from conventional work allocation in the CPU. Intel's Rentable Units does it without splitting the work into two threads and supposedly fills the gaps more efficiently than HT does, so this certainly helps, especially with a 4+4 configuration compared to 2+8.

So the Meteor Lake processor only has two HT cores? Well, that shows how little I know about mobile processors. I guess we'll have to wait for a more apples to apples comparison (same kind of cores) before taking proper conclusions.

Thank you.

Since Alder Lake Intel's ultrabook chips and below only have 2 P-cores and 4-8 E-cores. One of the main reason why I wouldn't buy one of them if I could avoid them; here AMD has a much better value proposition even with older CPUs. A Ryzen 5 5625U has the same 15W, the same 12 threads, but comes with only P-cores and 7CU GPU. And despite all being P-cores, AMD still has a higher base clock speed than Meteor Lake (1.6/1.1Ghz on Core Ultra 5 135U, 2.3Ghz on the Ryzen 5 5625U)

It's probably also why AMD went and released 2 (much-maligned) Zen 2 based chips last year in that segment, they're still powerful enough to keep up with Intel here even with just 4c/8t...
