Xeon E5-1660 v2 Details

The Intel Xeon E5-1660 v2 stands as a testament to the power of server-grade computing, even as it ages into the mid-2010s. Released in September 2013, this processor is built on Intel's Ivy Bridge-E architecture and is designed for demanding workloads in server and workstation environments. Though now over a decade old, its performance remains competitive in specific niches, particularly in multi-threaded applications. The processor features six cores with Hyper-Threading enabled, delivering 12 threads of processing power, a significant advantage in parallel computing tasks. It operates at a base frequency of 3.7 GHz and can boost up to 4.0 GHz, providing a robust performance profile for its time. Built on a 22 nm process, the Xeon E5-1660 v2 contains 1.86 billion transistors and is fabricated by Intel, showcasing the company's advanced manufacturing capabilities of that era.

In terms of memory and connectivity, the Xeon E5-1660 v2 supports quad-channel DDR3 memory with a maximum rated speed of 1866 MT/s, enabling a peak memory bandwidth of 59.7 GB/s. This makes it well-suited for data-intensive applications such as virtualization, database management, and scientific computing. The processor is designed for the Socket 2011 platform, requiring a compatible motherboard, and it supports ECC memory, a crucial feature for mission-critical systems where data integrity is paramount. With a TDP of 130 W, the Xeon E5-1660 v2 demands adequate cooling solutions, making it more appropriate for server chassis than compact desktop builds. Despite its lack of integrated graphics, the processor relies on external GPUs, a common design choice for professional workstations.

The Xeon E5-1660 v2 is equipped with a substantial 14.305 MiB L3 cache, which helps reduce memory latency and improve performance in complex workloads. It also supports a range of Intel technologies, including Intel Hyper-Threading, VT-x, VT-d, and EPT, enabling efficient virtualization and I/O virtualization. The processor supports advanced instruction sets such as AVX, SSE, and MMX, enhancing performance in multimedia, computational, and encryption tasks. However, its unlocked multiplier allows for easier overclocking, making it a favorite among enthusiasts despite its server-oriented design.

Benchmarking reveals that the Xeon E5-1660 v2 scores 5058 overall, placing it at #823 among 2060 processors. In single-core performance, it achieves a score of 5168, ranking #835, indicating strong per-core performance for its generation. Its multicore score of 4892 ranks it at #735, demonstrating its strength in multi-threaded applications. While these scores are impressive for a 2013 processor, they fall well behind modern high-end CPUs like the Ryzen Threadripper PRO 9995WX or the Core Ultra 9 285K, which dominate the top 50 lists. Nevertheless, the Xeon E5-1660 v2 holds its own against many contemporary mid-range processors, particularly in scenarios that benefit from its 12-thread architecture and ECC memory support.

As of March 2026, the Xeon E5-1660 v2 remains a viable option for legacy server systems, small business workstations, or users who require high multi-threaded performance without the need for cutting-edge single-core speeds. Its strong multicore performance and support for ECC memory make it suitable for virtualization, data processing, and other server-grade tasks. While newer processors have eclipsed its capabilities, the Xeon E5-1660 v2 still delivers reliable performance in environments where cost-effective, proven technology is prioritized over the latest innovations.
