Xeon E3-1240 v3 Details

As of March 2026, the Intel Xeon E3-1240 v3 remains a notable processor in the legacy server and workstation space, despite being over a decade old. Originally launched in June 2013, it was designed for entry-level server and workstation environments where reliability and ECC memory support were priorities. While no longer competitive in modern high-performance computing, it still holds relevance in niche use cases such as legacy system upgrades or low-power embedded workstations. The processor’s performance today is best understood in context—its benchmark results place it in the middle tier of a broad range of CPUs, reflecting both its age and the evolution of computing demands.

At its core, the Xeon E3-1240 v3 is built on Intel’s Haswell-WS architecture and manufactured on a 22 nm process, featuring 1.4 billion transistors and a die area of 160 mm². It delivers a base clock of 3.1 GHz, with a turbo frequency of 3.8 GHz, and supports a 5 GT/s bus speed. With four physical cores and four threads—thanks to Intel’s Hyper-Threading technology—it provides moderate multithreaded performance. The L3 cache stands at a generous 7.629 MiB, which aids in performance for data-intensive applications, while L1 and L2 caches measure 0.061 MiB and 0.244 MiB, respectively. It operates at a 65 W TDP and uses the FCLGA1150 socket, requiring compatible motherboards from the C226, 8 Series, or 9 Series chipsets.

Memory support includes dual-channel DDR3-1333/1600 and DDR3L-1333/1600 at 1.5V, with a maximum capacity of 32 GB and a bandwidth of 25.6 GB/s. ECC memory is supported, a key differentiator for enterprise use, ensuring data integrity in mission-critical applications. The processor also includes a range of modern features for its time, such as AVX, AVX2, AES-NI, and Intel VT-x with EPT for virtualization. It supports PCIe 3.0 with up to 16 lanes directly from the CPU, enabling fast storage and expansion options.

In terms of real-world performance, the Xeon E3-1240 v3 scores 5321 in the overall PassMark benchmark, ranking #600 out of 2060 processors. Its single-core score of 5516 places it at #542, indicating solid individual thread performance, while its multicore score of 5029 secures #618 in the multicore category. These results show that while the processor is capable in single-threaded tasks, its multithreaded performance is somewhat limited compared to modern CPUs. It outperforms several newer low-power and embedded processors but trails significantly behind today’s top-tier offerings like the Ryzen Threadripper PRO 9995WX or Core Ultra 9 285K.

The Xeon E3-1240 v3 does not include integrated graphics, so a discrete GPU is required for visual output. This makes it unsuitable for general desktop use without additional hardware. However, its combination of ECC support, stable performance, and virtualization capabilities makes it a viable option for small-scale virtualization hosts, NAS systems, or embedded servers where power efficiency and cost-effectiveness are key.

In conclusion, the Xeon E3-1240 v3 is a relic of the early 2010s, but it remains functional in specific scenarios. It offers a balance of performance, reliability, and efficiency for legacy environments. While it cannot compete with modern processors in either single-core or multicore performance, its support for ECC memory and virtualization ensures it still has a place in specialized workloads. For users maintaining older systems or seeking a low-cost server solution, it remains a practical, if dated, choice.
