Intel Core i5-4258U

2C/4T · 2.9 GHz · 28 W

The Intel Core i5-4258U is a dual-core processor from Intel's 4th Generation (Haswell) Core i5 family, launched in the third quarter of 2013 with Intel's higher-performance Iris graphics for premium thin-and-light laptops. It provides 2 cores with Hyper-Threading for 4 threads, a 2.40 GHz base clock with Turbo Boost up to 2.90 GHz, and 3 MB of Intel Smart Cache within a 28 W thermal envelope. Manufactured on Intel's 22 nm process for the soldered FCBGA1168 package, it pairs Intel Iris Graphics 5100 with dual-channel DDR3L memory at 1333/1600 MT/s up to 16 GB. Its higher 28 W power budget let it sustain stronger CPU and graphics clocks than the standard U-series parts, making it a step-up option for compact premium notebooks of its era.
