Core i7-620M Details

As of March 2026, the Intel Core i7-620M remains a relic of the early 2010s, a mobile processor launched in January 2010 with a $332 price tag. Despite its age, it still holds a place in historical benchmarks, reflecting the state of mobile computing during the Arrandale era. With a 32 nm manufacturing process and a TDP of just 35 W, the chip was designed for efficiency in laptops, though its performance is now significantly outpaced by modern processors. At a base clock of 2.677 GHz and a turbo frequency of 3.333 GHz, it leverages Intel Hyper-Threading to deliver four threads from its two physical cores, a feature that was forward-thinking for its time.

The Core i7-620M is built on the Arrandale microarchitecture and uses the BGA1288 socket, commonly found in laptops with Intel's PM55, HM55, and QM57 chipsets. It supports dual-channel DDR3 memory at up to 1066 MT/s, offering a memory bandwidth of 17.1 GB/s. The processor includes 4 MB of L3 cache, with 0.061 MiB of L1 and 0.244 MiB of L2 cache, a configuration that prioritized on-die memory access over raw capacity. Integrated HD Graphics (Ironlake) provides basic visual processing, though it lacks dedicated GPU power and is limited in modern graphics workloads.

In terms of real-world performance, the Core i7-620M scores 4337 overall, placing it #1480 out of 2060 processors in the Passmark ranking. Its single-core score of 4321 ranks it #1471, while its multicore score of 4362 positions it #1546. These figures highlight a processor that, while once competitive, now struggles to keep pace with even entry-level modern CPUs. It is outperformed by several AMD A-series and Intel Core i3 and i5 models, many of which are significantly newer and more efficient.

The Core i7-620M supports a range of Intel technologies, including SSE4.1, SSE4.2, EIST, VT-x, and VT-d, ensuring compatibility with virtualization and power management features. However, its locked multiplier limits overclocking potential, a common trait in mobile processors of the era. With a transistor count of 382 million and a die area of 81 mm², it represents a compact yet capable design for its time.

Today, the Core i7-620M is best suited for light office tasks or as a replacement in legacy systems where modern components are not feasible. For users seeking modern performance, it is far surpassed by current-generation processors, which deliver vastly superior single- and multicore performance while maintaining lower power consumption. Its historical significance lies in its role as a bridge between early dual-core mobile designs and the more advanced architectures that followed.
