Verdict

The Intel Core i5-1235U is a 12th Gen Alder Lake-U series mobile processor featuring 10 cores (2 Performance-cores and 8 Efficient-cores) and 12 threads with a max turbo frequency of 4.40 GHz and 12 MB of Smart Cache. Designed for thin-and-light laptops, its main pros include excellent energy efficiency with a 15W base power, integrated Intel Iris Xe graphics (80 EUs), and support for modern memory types like DDR5-4800 and LPDDR5-5200. However, its main cons are limited sustained performance in demanding tasks due to its low power envelope compared to H-series chips, and integrated graphics that are insufficient for high-end modern AAA gaming.
