how accurate are these numbers, the 1235U capable of 876M Primes/sec compared to 48m Primes/sec of the 1335U?

Both these CPUs are so close in performance that you would choose more on the price of the notebook. I bought a notebook with the 1235u which is fine for a daily workhorse laptop. It's not a P-core or a H-core laptop but at least it keeps up with the last-gen Core i7 U series. Nowadays, you just don't get leaps in performance even in a significant design change as the Intel P and E core. Low-powered chips like these are still low-powered. More efficient, then performance oriented. Nothing wrong with that, just that this new design does move the bar much. A different path to the same result.

149 pages/sec for the 1335u, is this data correct or is it an error? I'm referring to the HTML 5 Browser section. If this is correct then the 1235U beats the 1335U in that section.

Re-badged Alder Lake-U as "Raptor-Lake" with small overclocking. Lolz Intel.
