CPU Comparison

Core i7-5557U vs Core i7-5650U

A side-by-side comparison of specs, performance and value. The Intel Core i7-5557U is a higher-performance variant of the Broadwell-U mobile processor family, launched in 2015 to power premium thin-and-light laptops and mini PCs. Manufactured on a 14nm process, it features two cores and four threads, operating at a higher base clock of 3.1 GHz and boosting up to 3.4 GHz. This represents a significant frequency uplift compared to other U-series chips, sacrificing some efficiency for raw speed. The processor integrates Intel Iris Graphics 6100, equipped with 48 execution units, offering strong integrated graphics performance for its size. It includes 4 MB of L3 cache and operates within a 28-watt thermal design power, which is higher than the standard 15-watt U-series parts. Though end-of-life, the i7-5557U was highly regarded for providing desktop-like responsiveness and capable graphics in compact form factors, bridging the gap between ultra-low power and performance mobile computing indeed very truly.
