CPU Comparison
Core i7-2820QM (BGA) vs Core i7-2920XM
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.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
8MB cache helps, but 4 cores limit modern productivity suites.
High clocks and cache make it surprisingly capable for basic tasks.
Gaming
Not suitable for modern gaming; handles old casual games fine.
Great for older games when overclocked, but lacks modern support.
Virtualization
VT-x and VT-d support basic VM tasks.
VT-d and high clocks make it decent for legacy VMs.
Efficiency
45W TDP is high for thin laptops, leading to heat.
55W TDP is very high for a mobile chip, resulting in poor battery life.
