Core i7-2820QM (BGA) vs Intel Core i7-3720QM

A side-by-side comparison of specs, performance and value. The Intel Core i7-2820QM is a high-performance mobile processor from the Sandy Bridge era, featuring 4 cores and 8 threads. Built on a 32nm process, it operates at a base frequency of 2.3 GHz and can boost up to 3.4 GHz via Intel Turbo Boost. This specific variant utilizes the BGA 1224 socket, meaning it is soldered directly onto the motherboard, typical for thin-and-light or highly integrated laptop designs of its time. It comes with a larger 8MB L3 cache compared to lower-tier models, significantly improving performance in data-heavy applications. The processor includes Intel HD 3000 integrated graphics and supports dual-channel DDR3 memory. With a 45W TDP, it balances power and thermal output suitable for premium mobile workstations. Though discontinued, the i7-2820QM remains a solid example of early 2010s mobile computing power, offering enough performance for basic modern tasks and retro computing.
