Xeon E5-1660 v4 Details

Ranking #474 of 2060 in overall performance, the Intel Xeon E5-1660 v4 delivers a balanced blend of single-core and multi-threaded capabilities, positioning it as a capable server-grade processor for workstations and light enterprise environments. Released in 2016 as part of Intel's Broadwell-EP family, this CPU is now over seven years old, placing it firmly in the legacy category. Despite its age, the Xeon E5-1660 v4 remains a solid performer for workloads that benefit from its 8-core, 16-thread configuration and support for high-capacity memory.

Built on a 14 nm process, the Xeon E5-1660 v4 operates at a base clock of 3.2 GHz with a turbo frequency of 3.8 GHz, leveraging Intel's Turbo Boost 2.0 technology to scale performance under load. The processor features 2 MiB of L2 cache and a substantial 20 MiB L3 cache, which helps maintain high memory throughput for demanding applications. It supports up to 1.5 TB of DDR4 memory across four channels, with a maximum bandwidth of 5000 MT/s, making it suitable for memory-intensive tasks such as virtualization and data analysis.

The Xeon E5-1660 v4 operates at a TDP of 140 W and is compatible with the LGA 2011-3 socket, requiring a C610 series chipset for full functionality. While it lacks integrated graphics, its focus on compute performance is evident in its extensive feature set, including support for Intel VT-x, VT-d, and Intel TXT, along with advanced vector extensions like AVX and AVX2. It also includes Hyper-Threading, enabling efficient multitasking and parallel processing.

In benchmark testing, the Xeon E5-1660 v4 achieves an overall score of 5505, with a single-core score of 5497 and a multicore score of 5516. These results place it just behind the Xeon E-2146G and Ryzen 9 4900HS in multicore performance, while trailing slightly in single-core performance compared to the Core i5-6600 and Core i3-8300T. Its performance is competitive with several modern server and enthusiast-grade processors, particularly when considering its price point and availability in the used market.

As of March 2026, the Xeon E5-1660 v4 remains a viable option for users seeking a cost-effective, high-core-count CPU for workstations, small-scale servers, or legacy systems. While it is outpaced by newer architectures in terms of efficiency and raw performance, its robust feature set and support for ECC memory make it a reliable choice for professional applications where stability and compatibility are prioritized over cutting-edge performance.
