Core i7 940 Details

With a multicore score of 4692 and a single-core score of 4685, the Intel Core i7-940 stands as a mid-range processor from an era when Intel was still refining its high-performance desktop offerings. Released in 2010, this CPU is now over 15 years old, placing it firmly in the category of legacy hardware. Despite its age, the i7-940 remains notable for its use of the Nehalem microarchitecture, which brought significant improvements in instruction efficiency and memory bandwidth compared to its predecessors. Built on a 45 nm process, the chip operates at a base frequency of 2.93 GHz and can boost to 3.2 GHz, thanks to Intel's Turbo Boost technology. It features four cores and eight threads via Hyper-Threading, making it capable of handling moderately demanding multitasking and productivity workloads, even today.

The i7-940 is designed for the FCLGA1366 socket, which was a popular choice for enthusiast desktops during its time. It supports DDR3 memory at speeds up to 1066 MHz and can handle up to 24 GB of system memory across three channels, providing a bandwidth of 25.6 GB/s. The processor's TDP of 130 W indicates a power-hungry design, typical of high-end desktop CPUs from the late 2000s, and it requires a robust cooling solution. The integrated Intel HD Graphics GPU operates at 350 MHz with a burst frequency of up to 1100 MHz and supports up to three displays, making it suitable for basic multimedia tasks but not for gaming or GPU-intensive applications.

In terms of features, the i7-940 includes a comprehensive suite of Intel technologies such as AES-NI for encryption, AVX for vector processing, and VT-x for virtualization. It also supports ECC memory, although this is only available on certain motherboard platforms. The processor’s performance places it around the middle of the pack in both single-core and multicore rankings, ranking #1156 in single-core and #971 in multicore among 2060 CPUs. While it outperforms several modern low-power mobile processors, it falls far behind current-generation CPUs like the Ryzen 9 9950X3D or Core Ultra 9 285K.

As of March 2026, the Core i7-940 is best suited for legacy systems or retro builds where compatibility with older hardware is a priority. It can still handle basic office applications, light video editing, and media playback, but it is no longer competitive in modern computing environments. Its primary value today lies in historical significance and its role in the evolution of Intel's high-performance desktop lineup.
