Xeon E3-1585 v5 Details

Ranked #559 of 2060 in overall performance, the Intel Xeon E3-1585 v5 delivers a balanced mix of single-core and multi-core capabilities, with a standout single-core score of 5684—placing it at #432 in that category. This performance is particularly impressive given the processor's age, having been released in May 2016, making it over seven years old as of early 2026. While no longer competitive with modern high-end desktop or server CPUs, the Xeon E3-1585 v5 remains a viable option for legacy systems, light server workloads, or embedded applications where integrated graphics and ECC memory are essential.

Built on Intel’s Skylake-H architecture and fabricated on a 14 nm process, the Xeon E3-1585 v5 features four cores and eight threads thanks to Intel Hyper-Threading. It operates at a base frequency of 3.5 GHz, with a turbo boost up to 3.9 GHz, supported by a 65 W TDP that ensures efficient power consumption for its class. The chip includes 8 MB of L3 cache, 1 MB of L2 cache, and 0.25 MiB of L1 cache, enabling fast data access for compute-intensive tasks. It supports DDR3L and DDR4 memory at speeds up to 2133 MT/s via a dual-channel memory bus, with a maximum capacity of 64 GB.

The processor integrates Intel’s Iris Pro Graphics P580, which features 72 execution units and a maximum frequency of 1150 MHz, capable of driving up to three displays. This makes the Xeon E3-1585 v5 suitable for systems requiring basic graphics without a discrete GPU. It also supports ECC memory, a key advantage for server and workstation environments where data integrity is critical. Other notable features include AVX2, AES-NI, Intel VT-x and VT-d virtualization, and Intel vPro technology, which enhance security and virtualization performance.

In benchmarking, the Xeon E3-1585 v5 outperforms several modern CPUs in the single-core category, including the Core i5-9500F and Core i5-5675C, despite its older architecture. However, its multicore score of 4949 places it behind more recent quad-core and higher-core-count designs, indicating that its strengths lie in sequential workloads rather than parallel processing. The processor is outpaced by modern offerings such as the Ryzen 5 4500U and FX-9370 in multi-threaded performance, but it holds its own against some desktop CPUs from its era.

Overall, the Xeon E3-1585 v5 is best suited for older systems requiring a reliable, ECC-enabled processor with integrated graphics. While its performance is now niche, its combination of virtualization support, memory protection, and integrated GPU still makes it relevant in specific professional or legacy environments. As of March 2026, it remains a testament to Intel’s design philosophy from the mid-2010s, offering durability and reliability over raw speed.
