CPU Comparison

Intel Core i7-4850HQ vs Core i7-3840QM

A side-by-side comparison of specs, performance and value. The Intel Core i7-4850HQ is a high-end mobile processor launched in April 2013, sitting near the top of the Haswell Crystalwell hierarchy. Designed for premium gaming laptops and mobile workstations, it features four cores and eight threads, delivering formidable multitasking capabilities. Operating at a base frequency of 2.3 GHz and boosting up to 3.5 GHz, it provides excellent single-threaded performance for its generation. The inclusion of Intel HD Graphics 5200, backed by 128MB of L4 eDRAM, ensures that graphical workloads are handled with unprecedented efficiency for an integrated solution. This makes the chip highly versatile, capable of driving high-resolution displays and handling moderate 3D rendering without a dedicated GPU. With a 47-watt TDP, it requires a robust cooling solution but delivers desktop-class performance in a mobile footprint. Although end-of-life, the 4850HQ was a premier choice for power users demanding a balance of raw speed and graphical fidelity.

Our Verdict on Each

A 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.
