CPU Comparison
Intel Core i7-2635QM vs Core i7-2820QM (BGA)
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.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Adequate for basic tasks but slow for heavy workloads.
8MB cache helps, but 4 cores limit modern productivity suites.
Gaming
Obsolete for modern gaming; only handles old titles.
Not suitable for modern gaming; handles old casual games fine.
Virtualization
Supports VT-x but limited by locked nature.
VT-x and VT-d support basic VM tasks.
Efficiency
45W TDP is inefficient for modern mobile standards.
45W TDP is high for thin laptops, leading to heat.

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.
