Core i7-2620M Details

The Core i7-2620M, released in 2011 as part of Intel's Sandy Bridge M series, remains a notable mobile processor from the early era of modern multi-core laptop CPUs. Built on a 32 nm process and based on the Sandy Bridge microarchitecture, this dual-core, quad-threaded chip was designed for mainstream mobile performance with integrated graphics. Despite its age, the processor continues to serve as a reference point for understanding how mobile computing evolved over the past decade.

At its core, the i7-2620M operates at a base frequency of 2.7 GHz, with a turbo boost capability reaching up to 3.4 GHz under single-core load and 3.2 GHz with two cores active. It features 4 MB of L3 cache, 0.5 MB of L2 cache, and 0.125 MB of L1 cache split into 64 KB for instructions and 64 KB for data. The CPU supports DDR3-1333 and DDR3-1066 memory, with a maximum capacity of 16 GB across two channels and a peak memory bandwidth of 19.87 GB/s. It is packaged in the FCBGA-1023 and rPGA988B sockets and operates at a 35 W TDP, making it suitable for mid-range laptops of its time.

The processor integrates Intel HD Graphics 3000, which includes 12 execution units and a base frequency of 650 MHz, capable of boosting to 1.3 GHz. It supports up to two displays and offers basic multimedia acceleration, including support for H.264 and VC-1 decoding. While not a graphics powerhouse by modern standards, this GPU was adequate for light gaming and everyday productivity tasks in 2011.

The i7-2620M supports a wide range of Intel technologies, including AES-NI, AVX, Hyper-Threading, Intel Turbo Boost 2.0, and Intel vPro, which provided enterprise-level manageability and security features. It also includes full x86-64 instruction set support and extended page tables (EPT), enabling efficient virtualization. The chip is compatible with the Cougar Point chipset and features a 5 GT/s DMI 2.0 bus.

In benchmark testing, the Core i7-2620M achieves a Passmark Overall Score of 4545, placing it at #1239 out of 2060 processors. Its single-core score is 4613, ranking #1207, while its multicore performance scores 4443, placing it at #1337. These results indicate that the CPU is most competitive in single-threaded workloads, though its multicore performance lags behind modern processors. It outperforms older dual-core chips like the Athlon II X4 555 but falls short of modern mid-range CPUs such as the Core i5-5350U.

As of March 2026, the Core i7-2620M is considered obsolete for general computing, but it remains relevant in retro computing, vintage system restoration, or low-power embedded applications where its efficiency and integrated graphics are still functional. Its performance is comparable to early 2010s mobile processors, and while it cannot compete with today's high-end mobile CPUs, it represents a significant step in Intel's transition toward multi-core, high-efficiency mobile processors.
