Xeon E3-1240 v6 Details

As of March 2026, the Intel Xeon E3-1240 v6 remains a capable mid-tier server processor, offering a balanced blend of single-core performance and multi-threaded efficiency. With an overall score of 5592, it ranks #421 among 2060 processors, placing it in the upper tier of mainstream desktop and entry-level server CPUs. While not a flagship chip, its single-core performance of 5934 earns it a strong #297 ranking, showcasing its ability to handle modern workloads efficiently. The multicore score of 5079 positions it at #581, indicating solid scaling for multi-threaded applications, though it trails behind newer generation CPUs in both raw power and thermal efficiency.

The Xeon E3-1240 v6 is built on Intel's Kaby Lake microarchitecture, fabricated on a 14 nm process node. It features four physical cores with simultaneous multithreading (SMT), delivering eight logical threads for improved multitasking. Clock speeds reach up to 4.1 GHz in turbo mode, with a base frequency of 3.7 GHz. The processor includes a 1 MiB L2 cache and a substantial 8 MiB L3 cache, enhancing data access speeds for compute-intensive tasks. Memory support includes DDR3L-1866 and DDR4-2400, with dual-channel bandwidth reaching 35.76 GiB/s. It is designed for the LGA-1151 socket, making it compatible with a wide range of server and workstation motherboards.

Intel’s integrated features are robust, including support for ECC memory, which is crucial for data integrity in server environments. The processor also supports a variety of instruction sets such as AVX-2, AES-NI, and Intel’s Secure Key Technology, enhancing encryption and security capabilities. It also includes virtualization technologies like Intel VT-x and VT-d, which are essential for running virtual machines efficiently. Additionally, the chip features Intel’s Enhanced SpeedStep and Turbo Boost 2.0, allowing dynamic frequency adjustments based on workload and thermal conditions.

In terms of real-world performance, the Xeon E3-1240 v6 competes closely with processors like the Core i5-7600K and Core i7-8709G. Its single-core performance is particularly strong, rivaling some higher-end desktop chips from the same generation, while its multicore performance places it just behind modern quad-core CPUs with higher clock speeds or more advanced architectures. While it is not a leader in the current market, its TDP of 72 W ensures relatively low power consumption for a server-grade chip, making it suitable for systems where efficiency and reliability are priorities.

For users requiring a reliable, cost-effective CPU for light to moderate server workloads, virtualization, or small-scale data processing, the Xeon E3-1240 v6 remains a viable option. Though it is no longer at the forefront of performance, its combination of strong single-threaded performance, ECC memory support, and broad compatibility ensures it remains relevant in certain professional environments. However, for users seeking the latest performance gains or future-proofing, newer generations of Intel or AMD processors offer significantly higher performance and improved features.
