CPU Comparison

Core i7-3612QM vs Intel Core i7-2675QM

A side-by-side comparison of specs, performance and value. The Intel Core i7-3612QM is a high-performance mobile processor launched in April 2012 as part of the Ivy Bridge lineup. This 22nm quad-core CPU features Hyper-Threading, allowing it to process 8 threads concurrently. It operates at a base frequency of 2.1 GHz and boosts up to 3.1 GHz. The key differentiator of this SKU is its 35W TDP, significantly lower than the standard 45W found on the i7-3610QM, making it ideal for thinner gaming laptops and portable workstations. The processor is available in both Socket G2 (rPGA988B) and BGA 1224 formats. It includes 6MB of L3 cache and supports dual-channel DDR3-1600 memory. The integrated Intel HD Graphics 4000 handles basic display outputs and media decoding. The i7-3612QM offered an excellent compromise for users who wanted quad-core multi-threaded performance without the extreme heat and battery drain of higher-wattage mobile chips.

Our Verdict on Each

Core i7-3612QMSituational

A great low-power quad-core mobile CPU for 2012, offering excellent efficiency, but its lower clocks limit single-threaded performance.

Best for: Upgrading an old Socket G2 laptop for cheap

Read the full review

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.
