Intel Core i7-640M Details

Ranked #1347 of 2060 in overall performance, the Intel Core i7-640M delivers a benchmark score that places it firmly in the mid-tier of its generation. While its 4437 overall score may not stand out against modern processors, it's important to note that this CPU was released in 2010, making it over 15 years old as of 2026. For a mobile processor from that era, the i7-640M was a significant step forward, particularly for users seeking high performance in portable systems. Its dual-core design with hyper-threading enables efficient multitasking, and the 3.47 GHz turbo frequency provides a noticeable boost in single-threaded applications. The integrated HD Graphics (Ironlake) GPU supports up to two displays and runs at a maximum of 766 MHz, making it suitable for basic multimedia and light gaming, though it struggles with modern graphics demands.

Built on Intel's Westmere microarchitecture at a 32 nm process, the i7-640M features a 4 MB L3 cache and 0.5 MB of L2 cache, which contribute to its responsive performance. It supports DDR3-1066 memory at a maximum of 8 GB, with a memory bandwidth of 15.88 GiB/s, a standard for its time. The processor operates at a 35 W TDP, offering a balance between performance and power efficiency, and it uses a BGA-1288 or rPGA-988A package, common in laptops of the era. The i7-640M supports a range of advanced features, including Intel Turbo Boost 1.0, Enhanced SpeedStep, and virtualization technologies like VT-x and VT-d, making it a capable choice for business and productivity tasks.

In single-core performance, the i7-640M scores 4433, ranking #1354 of 2060, which reflects its strong clock speed and architectural optimizations. In multicore performance, it achieves a score of 4443, ranking #1337, indicating that it can handle parallel workloads reasonably well for its age. While it is outperformed by modern processors, it remains competitive with other CPUs from the same era, such as the Athlon X4 870K and Core i3-7020U, which have slightly higher scores. The i7-640M’s performance is most impressive when compared to older processors like the Core i3-3220T or Xeon E5-2609 v2, which it outperforms in both single- and multicore benchmarks.

As of March 2026, the Intel Core i7-640M is best suited for legacy systems, retro computing, or as a replacement in older laptops where upgrading the entire system is impractical. Its integrated graphics and power efficiency make it a practical choice for basic computing tasks, but it is not suitable for demanding applications like video editing or modern gaming. For enthusiasts or collectors, the i7-640M represents a notable chapter in Intel’s mobile processor history, showcasing the transition from dual-core to more advanced architectures in the late 2000s.
