CPU Comparison
Intel Core i7-3635QM vs Intel Core i7-4850HQ
A side-by-side comparison of specs, performance and value. The Intel Core i7-3635QM is a high-performance mobile processor launched in late 2012 as part of the Ivy Bridge generation. Designed for premium laptops and mobile workstations, it features four cores and eight threads, delivering robust parallel processing capabilities. It operates at a base clock of 2.4 GHz and can boost up to 3.4 GHz using Intel Turbo Boost 2.0. Unlike the socketed 3630QM, the 3635QM utilizes a BGA 1224 package, meaning it is soldered directly to the motherboard. This allows for slightly thinner laptop designs but prevents CPU upgrades. With a 45-watt thermal design power, it balances high performance with the thermal constraints of premium mobile chassis. The integrated Intel HD 4000 graphics offer capable multimedia decoding. This CPU was a popular choice for system integrators building compact, high-performance laptops where board space and component height were critical factors.

Our Verdict on Each
A capable mobile CPU that provided excellent quad-core performance for laptops in its era, utilizing a space-saving BGA design.
Best for: Purchasing a budget, used laptop for basic tasks or retro gaming.
Read the full reviewA flagship 2013 mobile processor combining strong quad-core clocks with the graphical prowess of Iris Pro and eDRAM.
Best for: If you are sourcing an Intel Core i7-4850HQ today, it is likely for repairing a vintage premium laptop, such as a 2013 MacBook Pro. The processor is end-of-life, but its 3.5 GHz turbo and HD 5200 graphics still pack a punch for retro gaming and 1080p media editing. When evaluating a system with this chip, pay close attention to the thermal paste and fan condition; a 47W Haswell chip will throttle heavily if overheating. If you are performing a BGA replacement, ensure your soldering profile matches the 1364 ball grid array. For general consumers, do not purchase a laptop with this CPU as a primary machine. Modern budget processors offer vastly superior battery life and single-core performance. However, if you need a cheap, capable machine for running older creative software or acting as a localized media server, a functional 4850HQ system can still provide excellent value at the right price.
