Core i5-7440HQ vs Intel Core i7-3635QM

A side-by-side comparison of specs, performance and value. The Intel Core i5-7440HQ is a 7th generation mobile processor designed for high-performance laptops. Released in early 2017, it belongs to the Kaby Lake-H family, characterized by a 45W TDP tailored for thicker gaming and workstation laptops. Featuring 4 cores and 4 threads, it operates at a base frequency of 2.8 GHz and can boost up to 3.8 GHz. The processor is built on Intel's 14nm process and integrates the Intel HD Graphics 630, handling everyday display tasks and light media decoding. Unlike its desktop counterparts, the 7440HQ is soldered onto BGA1440 motherboards, meaning it cannot be upgraded. It supports both DDR4 and DDR3L memory, offering flexibility for manufacturers. Positioned as a mid-range mobile chip, it provided a solid balance between power and thermal output, making it a common choice in budget gaming laptops and mobile workstations where dedicated graphics handled the heavy lifting.
