Verdict

The Intel Core i3-5157U is a dual-core Broadwell processor launched in early 2015, featuring 4 threads via Hyper-Threading, a base frequency of 2.50 GHz, and a 3 MB L3 cache. Manufactured on a 14nm process, its standout characteristic is the integrated Intel Iris Graphics 6100, which offers 48 execution units and supports up to three displays. Main pros include its relatively high base clock for an i3 of its era, support for faster LPDDR3-1866 memory, and sufficient performance for multitasking and light productivity. However, its 28W TDP makes it less energy-efficient than typical 15W 'U' series chips, and its lack of Turbo Boost significantly limits single-threaded performance in demanding tasks.
