CPU Comparison

Core i7-3525M vs Core i7-3540M

A side-by-side comparison of specs, performance and value. The Intel Core i7-3525M is a mainstream mobile processor launched in November 2012 as a minor refresh within the Ivy Bridge lineup. This 22nm dual-core CPU features Hyper-Threading, processing 4 threads concurrently. It operates at a base frequency of 2.9 GHz and boosts up to 3.6 GHz. The key differentiator of this SKU is its exclusive use of the BGA 1023 socket, meaning it is soldered directly to the motherboard and cannot be upgraded. With a 35W TDP, it targets standard laptop chassis with active cooling. It includes 4MB of L3 cache and supports dual-channel DDR3-1600 memory. The integrated Intel HD Graphics 4000 handles display outputs and media decoding. The i7-3525M was designed for premium business laptops where space-saving and durability were prioritized over modularity, offering excellent single-threaded responsiveness for office applications and legacy software.
