CPU Comparison
Core i7-3840QM vs Intel Core i7-4700HQ
A side-by-side comparison of specs, performance and value. The Intel Core i7-3840QM is a high-end mobile processor from the Ivy Bridge generation, designed to deliver robust performance for demanding laptop users. Released in September 2012, this quad-core CPU operates at a base frequency of 2.8 GHz and can boost up to 3.8 GHz using Intel's Turbo Boost technology. With eight threads thanks to Hyper-Threading, it handles multitasking and parallel workloads efficiently. The processor is built on a 22-nanometer manufacturing process, marking a significant shrink from the previous 32nm Sandy Bridge architecture. This allowed Intel to pack 1.4 billion transistors into a 160 mm² die while maintaining a reasonable 45-watt thermal design power. Featuring 8 MB of L3 cache, the i7-3840QM ensures quick data access for demanding applications. It also integrates Intel HD Graphics 4000, providing capable everyday graphics performance without needing a discrete GPU. This specific BGA variant is soldered directly to the motherboard, making it common in thinner, high-performance laptops of its era where upgradeability was sacrificed for compact form factors.

Our Verdict on Each
For its time, the i7-3840QM was a mobile powerhouse offering excellent multi-threaded performance, though its soldered BGA package limits modern upgradeability.
Best for: Repairing an existing 2012-era premium laptop.
Read the full reviewA reliable workhorse that powered countless mid-range gaming laptops, though obsolete by modern standards.
Best for: Locating an Intel Core i7-4700HQ today means searching the used market, as it has been end-of-life for several years. For consumers looking to purchase a budget-friendly used laptop, a machine equipped with this processor can still handle everyday tasks, light photo editing, and older games reasonably well. However, its 47-watt power draw and older 22nm architecture mean battery life will be subpar compared to modern ultrabooks. If you are repairing an existing laptop, this CPU remains a solid component, provided the motherboard and cooling system are in good condition. Do not invest in a system with this chip if your goal is modern AAA gaming or heavy video editing; the lack of modern instruction sets and single-core performance will be a severe bottleneck. Instead, view it as a capable retro-gaming or basic productivity companion.
