CPU Comparison
Intel Core i7-2635QM vs Intel Core i7-2675QM
A side-by-side comparison of specs, performance and value. The Intel Core i7-2635QM is a BGA-packaged mobile processor that brought quad-core performance to thinner and more compact laptops in 2011. Based on the Sandy Bridge architecture, it features four cores and eight threads, delivering excellent multitasking capabilities. Operating at a 2.0 GHz base clock and boosting up to 2.9 GHz, it offered the same performance as the socketed i7-2630QM but was soldered directly to the motherboard via BGA 1223. The 32nm process housed 1,160 million transistors and a 6MB L3 cache. With a 45W TDP, it was designed for performance laptops rather than ultrabooks. It included Intel HD 3000 integrated graphics for everyday multimedia tasks. While lacking an unlocked multiplier, the i7-2635QM supported AVX and AES-NI, making it a powerful and permanent solution for portable systems requiring robust computational power without the need for future upgrades.

Our Verdict on Each
A reliable soldered mobile CPU that offered great performance for its time, now obsolete and non-upgradable.
Best for: The Core i7-2635QM is an obsolete, soldered mobile processor that cannot be upgraded. If you own a laptop with this chip, it is still functional for basic computing, media playback, and web browsing. Adding an SSD and upgrading the RAM can significantly improve the responsiveness of the system for legacy use. However, it is completely unsuitable for modern gaming or heavy productivity tasks. If the laptop fails, it is generally not worth repairing the motherboard due to the age of the platform. For new purchases, modern laptops offer exponentially better performance, battery life, and features. The i7-2635QM should only be maintained in working devices, not sought out for new builds or repairs.
