Core i5-1235U Details

Built on Intel's Alder Lake-U architecture and fabricated on a 10 nm process, the Core i5-1235U is a mobile processor launched in February 2022. Though now over four years old, it remains a relevant option for thin and light laptops due to its balanced performance and low power consumption. The chip features a hybrid design with 10 cores—comprising 2 performance cores and 8 efficiency cores—and supports Intel's Hyper-Threading technology, delivering 12 threads for improved multitasking and workload throughput. Operating at a base frequency of 1.3 GHz, it can boost up to 4.4 GHz under load, making it capable of handling demanding applications when needed. The processor integrates 12 MB of L3 cache and supports both DDR4 and DDR5 memory across a dual-channel bus, ensuring efficient memory access for productivity and content creation tasks.

The Core i5-1235U includes Intel's Iris Xe graphics with 80 execution units, capable of running modern games at lower settings and supporting up to three simultaneous displays. It also features a range of modern instruction sets, including AVX2, AVX-512 (though limited in availability), and Intel's advanced virtualization technologies such as VT-x and VT-d, enabling robust virtual machine performance. The processor operates within a 15 W TDP, making it ideal for fanless or low-noise systems, and is packaged in a BGA 1744 configuration, which is common for integrated mobile designs.

In benchmark testing, the Core i5-1235U achieves an overall score of 5563, placing it at #441 out of 2060 processors, with a single-core score of 5840 (#337) and a multicore score of 5148 (#541). While it trails behind the top-tier processors like the Ryzen Threadripper PRO 9995WX and Intel's Core Ultra 9 285K, it competes closely with mid-range mobile and desktop CPUs such as the Ryzen 5 4600H and Core i7-1165G7. Its strongest performance lies in single-threaded workloads, where it ranks among the upper tier of mobile processors, though its multicore performance is more modest due to its lower core count and integrated nature.

As of March 2026, the Core i5-1235U is best suited for users seeking a balance between performance and power efficiency in thin-and-light laptops. It remains a solid choice for everyday computing, office productivity, light content creation, and casual gaming. While newer processors offer better performance and features, the i5-1235U still holds its own in the mobile segment, particularly for users who prioritize portability and battery life without sacrificing too much processing power.
