CPU Comparison
Intel Core i7-3635QM vs Intel Core i7-4950HQ
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.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
8 threads handle everyday multitasking and office workloads without issues.
Handles everyday tasks well, but slow by modern standards.
Gaming
Handles older or eSports titles well when paired with a discrete GPU.
Competent for 2013 games, but struggles with modern titles.
Virtualization
Can run light VMs, but limited by DDR3 bandwidth and 45W power.
Adequate for basic VM usage.
Efficiency
22nm Ivy Bridge is not as efficient as modern mobile processes.
High TDP and 22nm process result in poor battery life.

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 reviewAn important step forward for mobile integrated graphics, offering unique overclocking potential, but now obsolete.
Best for: Purchasing a used laptop at a rock-bottom price. Buying advice for the Core i7-4950HQ today suggests avoiding significant investment. While it was a formidable processor in its prime, modern applications and operating systems demand greater efficiency and newer instruction sets. If you encounter a used laptop featuring this chip at a very low price, it can still serve adequately for web browsing, office tasks, and media playback. However, its 47-watt TDP and older 22nm process mean it will run warmer and consume more power than modern equivalents. For gaming or content creation, its integrated graphics, while historically significant, no longer meet modern baseline requirements. Save your budget for a newer system that offers better longevity.
