Core i7-3820QM Details

The Core i7-3820QM, released by Intel in 2012, is a quad-core mobile processor built on the 22 nm process and based on the Sandy Bridge microarchitecture. Designed for high-performance laptops, this CPU delivers a base clock of 2.7 GHz and can boost up to 3.7 GHz using Turbo Boost technology. With 8 threads enabled via Hyper-Threading, the i7-3820QM was a significant step forward in mobile computing at the time, offering strong multitasking capabilities and efficiency for its era. The processor operates at a 45 W TDP, making it suitable for performance-oriented notebooks that balance power and thermal constraints.

It supports DDR3-1333/1600 memory across two channels, with a maximum capacity of 32 GB and a memory bandwidth of 25.6 GB/s. Integrated into the chip is the Intel HD Graphics 4000 GPU, which runs at 650 MHz base frequency and can reach 1.25 GHz in burst mode, supporting up to three displays and providing adequate graphics performance for general use and light gaming. The CPU features a range of modern instruction sets, including AVX2, AES-NI, SSE4.1/4.2, and VT-x, along with advanced virtualization and security technologies like TXT, SMEP, and Intel vPro. Despite being over a decade old, the i7-3820QM remains competitive in certain benchmarks, particularly in single-threaded performance.

In the Passmark data, it achieves a single-core score of 4947, placing it at #973 of 2060, and a multicore score of 4773, ranking #883 of 2060. The overall score of 4877 lands it at #974 of 2060, with it narrowly outperforming similar processors like the Core i7-4710HQ and FX-9590. However, in today’s context, it trails far behind modern CPUs such as the Ryzen Threadripper PRO 9995WX or Core Ultra 9 285K, which dominate the top of the performance charts. While the i7-3820QM is no longer suitable for cutting-edge applications, it remains a capable processor for legacy systems, light productivity, and basic multimedia tasks.

As of March 2026, its relevance is largely historical, serving as a benchmark for how far mobile computing has evolved over the past decade.
