Let’s open a topic about the Intel Core i5-1334U laptop CPU. Not a whole lot interesting chip released in 2023, but it’s frequently used in lower mid range laptops, including those listed in 2025 Black Friday catalogs.

The i5-1334U is basically the same as the i5-1335U. The only notable difference I find is that the 1334U supports up to LPDDR5/x 5200MT/s RAM, while the 1335U goes up to LPDDR5/x 6400 MT/s.

Yes, there are differences in aggregated benchmarks in favor of the 1335U, but that likely  because some of the benchmarked laptops with it actually do utilize 6400MT/s RAM.
