CPU Comparison
Core i7-2860QM (rPGA) vs Intel Core i7-3820QM
A side-by-side comparison of specs, performance and value. The Intel Core i7-2860QM is a high-end mobile processor released in late 2011 as part of the Sandy Bridge refresh. Utilizing the Socket G2 (rPGA988B) interface, this 4-core, 8-thread CPU is highly sought after by enthusiasts looking to maximize the performance of older laptops. It boasts a base clock of 2.5 GHz and a maximum turbo frequency of 3.6 GHz, making it one of the fastest mobile quad-cores of its generation. The 8MB L3 cache ensures excellent performance in data-heavy applications. Built on a 32nm process, it has a 45W TDP, requiring robust cooling. The inclusion of Intel HD 3000 graphics allows for decent multimedia playback, though it is paired with discrete graphics in most systems it was sold in. This socketed version allows for easy installation and upgrades, a rarity in modern laptops.
