Core i5-7640X Details

The Intel Core i5-7640X stands out for its strong single-core performance, ranking #255 in single-core benchmarks with a score of 6038. This 4-core, 4-thread processor, launched in June 2017, is built on Intel's Kaby Lake X microarchitecture and features a 14 nm manufacturing process. Operating at a base frequency of 3.9 GHz, it can boost up to 4.2 GHz under load, delivering impressive clock speeds for its era. Despite being over six years old, its high clock frequency allows it to hold its own against some modern mid-range CPUs in single-threaded workloads.

The processor is designed for desktop use and utilizes the FCLGA-2066 socket, requiring a compatible LGA-2066 motherboard. It supports DDR4-2666 memory across a quad-channel memory interface, enabling a maximum memory bandwidth of 39.74 GiB/s. With a TDP of 112 W, the i5-7640X demands robust cooling solutions, especially when overclocked. It also supports up to 64 GB of system memory and features a 6 MB L3 cache, with 1 MB of L2 cache and 0.25 MiB of L1 cache split between instruction and data.

The Core i5-7640X does not include integrated graphics, requiring a discrete GPU for visual output. However, it supports a wide range of modern instruction sets, including AVX, AVX2, SSE4.1, SSE4.2, and AES-NI, enhancing performance in multimedia, encryption, and computational tasks. It also includes Intel's Turbo Boost 2.0 and Enhanced SpeedStep technologies for dynamic frequency scaling and power efficiency.

In multicore performance, the i5-7640X achieves a score of 4923, placing it at #701 overall in multicore rankings. While it holds a solid position in single-core tasks, its multicore performance is more modest compared to contemporary processors, reflecting its age and lack of multi-threading support. It competes closely with processors like the Core i5-8500B and Xeon E3-1246 v3 but falls behind newer offerings such as the Core i5-9400T and Xeon E-2244G.

As of March 2026, the Core i5-7640X remains a capable processor for legacy systems and budget builds, particularly where high clock speeds and single-threaded performance are prioritized. Its high TDP and lack of integrated graphics limit its appeal for modern mainstream use, but it remains relevant in niche applications such as overclocking, retro computing, or systems where its specific socket and chipset compatibility are required.
