CPU Comparison

Core i7-3920XM vs Core i7-2960XM

A side-by-side comparison of specs, performance and value. The Intel Core i7-3920XM Extreme Edition is a top-tier mobile processor launched in April 2012 based on the Ivy Bridge architecture. As an 'XM' series chip, it features an unlocked multiplier, a rarity for mobile CPUs, allowing enthusiasts to overclock it beyond its factory 2.9 GHz base clock. With 4 cores and 8 threads, it reaches up to 3.8 GHz via Turbo Boost. Built on the 22nm process, it packs 1.4 billion transistors into a 160 mm² die. Unlike standard mobile chips, it carries a 55W TDP to accommodate the increased power limits and overclocking headroom. It includes 8MB of L3 cache and integrates Intel HD 4000 graphics. This processor was the absolute pinnacle of mobile computing performance in 2012, designed for the most expensive, thick, and heavy gaming laptops and mobile workstations where cooling capacity allowed for sustained high-frequency operation and manual tuning by power users.
