Xeon E3-1240 v5 Details

As of March 2026, the Intel Xeon E3-1240 v5 remains a notable server/workstation processor, despite being over a decade old. Launched in October 2015, it belongs to the Skylake-DT family and is built on a 14 nm process using 1.75 billion transistors. While no longer competitive with modern high-end CPUs, it still holds relevance in legacy systems and entry-level server environments due to its robust feature set and ECC memory support. The processor features four cores with Hyper-Threading, effectively delivering eight threads, and operates at a base frequency of 3.5 GHz, boosting up to 3.9 GHz under load. This makes it capable of handling moderate multitasking and virtualization workloads efficiently.

The Xeon E3-1240 v5 is designed for the LGA-1151 socket and supports dual-channel DDR3L-1600 and DDR4-2133 memory, with a maximum capacity of 64 GB. Its 80 W TDP requires adequate cooling, especially in densely packed server environments. The chip integrates 8 MB of L3 cache, enhancing data access speed, while L1 and L2 caches measure 0.125 MB and 1 MB, respectively. It also supports PCIe 3.0 with 16 lanes directly from the CPU, enabling high-speed connectivity for storage and expansion cards. Notably, it lacks integrated graphics, meaning a discrete GPU is required for any display output.

In terms of performance, the Xeon E3-1240 v5 scores 5277 overall, placing it at #637 among 2060 processors in the Passmark ranking. Its single-core score of 5561 ranks it #507, indicating strong individual thread performance, while its multicore score of 4851 places it at #785. This suggests the processor excels in single-threaded applications but trails significantly in multi-threaded workloads compared to modern alternatives. It outperforms some older Xeon and Core i7 models, such as the Core i7-4770 and Xeon D-2123IT, but falls behind newer CPUs like the Core i5-7440EQ and Pentium Gold G7400 in multicore performance.

The processor supports a wide range of Intel technologies, including Intel VT-x and VT-d for hardware virtualization, Intel Secure Key, Intel vPro, and Intel Trusted Execution Technology. It also includes advanced instruction sets like AVX, AVX2, and AES-NI, which accelerate encryption and scientific computations. ECC memory support ensures data integrity in mission-critical environments, making it suitable for small business servers or workstations where reliability is paramount. Despite its age, the Xeon E3-1240 v5 remains a viable option for legacy systems, virtualization, and light server tasks due to its balanced performance and enterprise-grade features.
