CPU Comparison
Intel Core i7-2675QM vs Intel Core i7-2715QE
A side-by-side comparison of specs, performance and value. The Intel Core i7-2675QM is a BGA-packaged mobile processor released in late 2011 as a soldered alternative to the 2670QM. Based on the Sandy Bridge architecture, it features four cores and eight threads, delivering robust multitasking capabilities. Operating at a 2.2 GHz base clock with a 3.1 GHz turbo boost, it offered the same performance as the 2670QM but was permanently attached to the motherboard via BGA 1224. The 32nm chip integrated 1,160 million transistors and a 6MB L3 cache. With a 45W TDP, it was designed for performance-oriented laptops where space was constrained. It included Intel HD 3000 integrated graphics for everyday multimedia. While locked for overclocking, the i7-2675QM supported AVX and AES-NI, making it a highly capable and durable 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 i7-2675QM 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 i7-2675QM should only be maintained in working devices, not sought out for new builds or repairs.
Read the full reviewA solid embedded quad-core CPU that provided excellent longevity for industrial applications, now obsolete.
Best for: The Core i7-2715QE is an End-of-Life processor that is no longer viable for new designs. Because it is a BGA-packaged chip, it is soldered directly to the motherboard and cannot be upgraded. If you are maintaining an older embedded system or industrial PC that uses this processor, it remains functional for basic tasks and legacy software. However, any new project should utilize modern Intel or AMD embedded processors that offer significantly better performance per watt, smaller footprints, and modern I/O like PCIe 4.0 and USB 3.2. Finding replacement boards for this chip is becoming difficult, making it a poor choice for critical infrastructure. It is best left to repair existing hardware rather than seeking it out for new builds.
