Intel Xeon E5-2660 V4 CPU SR2N4 Processor

Name: Intel Xeon E5-2660 V4 CPU SR2N4 Processor
Brand: Intel
SKU: Xeon E5-2660 V4

Overview

The Intel Xeon E5-2660 V4 (SR2N4) is a 14-core, 28-thread processor built on Intel's Broadwell microarchitecture at 14nm, targeting the LGA2011-v3 dual-socket server and workstation platform. Base clock sits at 2.0 GHz with Turbo Boost reaching 3.2 GHz — numbers that illustrate the Xeon design philosophy: optimize for thread count and memory bandwidth over single-core clock speed. The chip supports 4-channel DDR4 ECC registered memory at up to 2400MHz, providing the error-correcting memory access essential for enterprise and scientific computing. At 105W TDP, it sits in the mid-range of the E5-2600 V4 lineup and can be cooled without the most extreme server thermal solutions.

The E5-2660 V4 is a workstation builder's chip for heavily parallelized workflows: Blender rendering, Cinebench multi-core benchmarks, FFmpeg encoding pipelines, and simulation software that distributes work across dozens of threads will all benefit from the 28-thread ceiling. In dual-socket boards — where two E5-2660 V4 CPUs operate simultaneously — the combined 56 threads provide throughput that current mid-range consumer platforms cannot match at comparable cost in the surplus market. The trade-off is clear: this CPU does not belong in a gaming rig or fast-launch workstation. Single-threaded responsiveness is limited, and the platform age means buyers are committing to a legacy ecosystem. It is purpose-built for throughput, and in that context, it continues to deliver value.

Pros & Cons

👍 Pros

14 cores and 28 threads via Hyper-Threading provide workstation-class parallel processing throughput for rendering and simulation workloads
Dual-socket platform support doubles addressable core count to 28 cores and 56 threads in a two-CPU configuration — a topology unavailable with consumer processors
4-channel DDR4 ECC memory support enables error-correcting memory configurations critical for data integrity in scientific or server applications
105W TDP positions the E5-2660 V4 as a thermally moderate choice among LGA2011-v3 Xeon chips, simplifying cooler selection versus higher-TDP variants
Broadwell microarchitecture (14nm) provides improved instructions-per-clock efficiency over prior Ivy Bridge-EP Xeon generation

👎 Cons

2.0 GHz base clock is low by any modern standard — single-threaded applications, gaming, and fast-launch software will feel sluggish compared to current-generation consumer CPUs
The LGA2011-v3 platform is a legacy ecosystem — new DDR4 server memory and compatible motherboards are increasingly sourced from surplus markets, complicating build planning
No integrated graphics — a discrete GPU or server graphics card is mandatory, adding cost and a potential failure point
PCIe 3.0 with no PCIe 4.0 or 5.0 support means storage and GPU bandwidth is capped at generation-3 speeds, which bottlenecks NVMe drives and high-bandwidth GPUs
BIOS microcode updates are no longer actively maintained by Intel, leaving the platform without forward security patches for server deployments

Frequently Asked Questions

What socket does the Intel Xeon E5-2660 V4 require, and what platforms does it support?

The E5-2660 V4 uses the LGA2011-v3 socket and is designed for Intel's C610 series chipset platforms — including Xeon E5 V4-class server boards and dual-socket workstation platforms. It is not compatible with consumer LGA2011-3 boards designed for Core X-series chips without careful platform verification.

How many cores and threads does the E5-2660 V4 provide, and what is the clock speed?

The E5-2660 V4 features 14 cores and 28 threads via Hyper-Threading, with a 2.0 GHz base clock and Turbo Boost up to 3.2 GHz. For applications that scale across threads — rendering, simulation, database queries — 28 logical processors represent a significant throughput advantage over consumer chips of the same era.

What is the TDP of the E5-2660 V4, and what cooling is required?

TDP is rated at 105W. That is a meaningful heat output requiring a server-class or high-performance workstation cooler — standard consumer CPU coolers with LGA2011-3 mounting brackets may work physically but should be rated for ≥105W TDP. In 1U or 2U server chassis, active cooling with adequate airflow is essential.

What memory does the E5-2660 V4 support, and how much can it address?

The E5-2660 V4 supports DDR4 ECC registered memory across 4 memory channels per socket, with a maximum memory speed of 2400MHz. In a dual-socket configuration, total addressable memory depends on the platform's DIMM slot count — typically up to 512GB per socket in enterprise configurations.

Is the E5-2660 V4 still a viable processor for workstation builds today?

For heavily threaded workloads — 3D rendering, video encoding, scientific computing — the 28-thread configuration remains capable at its price point in the used/surplus market. Its single-threaded performance is limited by the 2.0 GHz base clock, so it underperforms modern consumer chips in lightly threaded applications. It makes the most sense in dual-socket configurations that leverage its multi-CPU platform support.
