CPU Comparison
Intel Core i7-2635QM vs Intel Core i7-2720QM (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.
Good for basic office work but slow for heavy web apps.
Gaming
Obsolete for modern gaming; only handles old titles.
Handles old games well but bottlenecks modern GPUs.
Virtualization
Supports VT-x but limited by locked nature.
VT-d support makes it decent for legacy VMs.
Efficiency
45W TDP is inefficient for modern mobile standards.
45W TDP is high, leading to poor battery life.

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.

Best for: The Core i7-2720QM is an obsolete processor that should not be sought out for new purchases. However, if you already own a laptop with this chip, it remains viable for basic tasks like web browsing, document editing, and media playback. Its VT-d support makes it interesting for legacy virtualization projects, provided the laptop has enough RAM. If your laptop still functions, adding an SSD and maxing out the RAM can breathe new life into it. For any new computing needs, modern laptops offer vastly superior performance, battery life, and features. The i7-2720QM is best left as a component in functioning legacy devices rather than a target for upgrades.
