Core i7-2820QM Details

For users seeking a balance of performance and power efficiency in mobile computing, the Intel Core i7-2820QM stands as a capable option from an earlier generation of laptop processors. Released in 2011, this CPU is now considered outdated by modern standards, but it was once a flagship mobile part in Intel's Sandy Bridge M series. Built on a 32 nm process and based on the Sandy Bridge microarchitecture, the i7-2820QM was designed for high-end laptops and workstations, offering a blend of single-core speed and multi-threaded performance for its time.

The processor features four cores and eight threads, thanks to Intel's Hyper-Threading technology, allowing it to handle demanding multitasking and productivity workloads effectively. It operates at a base frequency of 2.3 GHz, with a turbo boost up to 3.4 GHz on a single core, dropping to 3.3 GHz on two cores, and 3.1 GHz on three or four cores. The chip includes 8 MiB of L3 cache, 1 MiB of L2 cache, and 0.25 MiB of L1 cache, distributed across the cores to ensure fast data access. It supports DDR3-1600, DDR3-1333, and DDR3-1066 memory across two channels, with a maximum memory capacity of 32 GB and a peak memory bandwidth of 23.84 GB/s.

Intel's integrated HD Graphics 3000 GPU is also a notable feature, featuring 12 execution units and a base frequency of 650 MHz, with a maximum dynamic frequency of 1300 MHz. This GPU supports up to two displays and provides basic multimedia and light gaming capabilities, though it falls far short of modern integrated graphics solutions. The CPU operates at a 45 W TDP, making it suitable for performance-oriented laptops with adequate cooling, and it uses the Socket G2 (rPGA988B) package.

In benchmark testing, the Core i7-2820QM achieves a multicore score of 4692, placing it at #971 among 2060 processors, and a single-core score of 4720, ranking #1137. Its overall score of 4709 lands it at #1095 in the overall ranking. While it outperforms several modern and older CPUs in its multicore and single-core scores—such as the Core i3-3220 and Pentium G3220—its performance is now overshadowed by contemporary processors. It falls behind top-tier models like the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, which score over 9000 and 8000 respectively.

The i7-2820QM supports a wide range of features, including Intel Turbo Boost 2.0, Enhanced SpeedStep Technology, Intel vPro, and Intel VT-x and VT-d virtualization. It also includes AES-NI, AVX, and SSE4.2 instruction sets, making it suitable for encryption, multimedia encoding, and scientific computing. However, it lacks support for ECC memory and modern memory types like DDR4 or DDR5.

As of March 2026, the Core i7-2820QM is best suited for legacy systems, retro computing projects, or low-cost upgrades in older laptops where discrete graphics are not required. Its performance, while impressive for its era, is no longer competitive in the current market, where even mid-range mobile processors outperform it significantly. For users seeking modern performance, newer Intel and AMD platforms offer far superior efficiency and power.
