About Intel Core i5-1235U

The Intel Core i5-1235U is built on the 10 nm Alder Lake‑U hybrid architecture, combining four high‑performance Golden Cove cores with six efficient efficiency cores for a total of ten cores and twelve threads. Its performance cores run at a modest 1.3 GHz base frequency but can boost up to 4.4 GHz under load, while the efficiency cores maintain lower power draw at their own dynamic frequencies. With a configurable TDP of 15 W, the chip balances mobile battery life and sustained performance, scaling power draw according to the workload and the system’s thermal envelope. A shared 12 MB L3 cache sits atop the core cluster, providing low‑latency data access that benefits both single‑threaded and multithreaded tasks, while each core also enjoys private L1/L2 caches. PassMark scores of 147,450 in data compression, 48,553 in integer math, and 43,303 in floating‑point math illustrate its strong mixed‑type capabilities, and the 12,923 multithread score confirms effective scaling across all cores. These characteristics make the i5‑1235U especially well‑suited for productivity suites, light content creation, code compilation, and moderate gaming at 1080p when paired with a capable GPU. Overall, the processor delivers a compelling blend of efficiency and performance for ultrathin laptops and convertibles that demand long battery life without sacrificing responsiveness.
