Intel Xeon E5-1686 v3

The Intel Xeon E5-1686 v3 is a 12-core, 24-thread Haswell-EP processor from Intel’s Server/Workstation segment. It runs on Intel Socket 2011-3, with a 2.60 GHz base clock and a 3.30 GHz boost clock, and it is rated at 135 W TDP. The chip is built on Intel’s 22 nm process, integrating 2,600 million transistors on a 356 mm² die. It supports DDR4 through a quad-channel memory bus with ECC and a memory bandwidth of 68.3 GB/s. The processor exposes 40 PCIe Gen 3 lanes from the CPU, has no integrated graphics, and has a locked multiplier. Production status is end-of-life, and the release date is 2014-09-07. The database record contains no benchmark scores, no average score, and no nearest rivals; the only global data point is percentileVsAllCpus of 50.

Benchmark Performance

The avgBenchmarkScore field is 0, and the benchmarks array is empty. This means the record carries no sample results from which to compute a multi-core or single-core score. The nearestRivals array is also empty, so there are no deltaPct values to place beside a competing product. The only comparative number is percentileVsAllCpus: 50, which places the E5-1686 v3 at the midpoint of the database’s CPU distribution. Because no rival scores are present, a percentage lead or deficit cannot be stated from the data. What the record does provide are architectural performance indicators: 12 cores, 24 threads, 2.60 GHz base, 3.30 GHz boost, 30 MB shared L3, and 68.3 GB/s memory bandwidth. These values indicate a multi-threaded-centric profile, but they are not benchmark scores and should not be treated as one.

Who Should Consider It

The segment field identifies this processor as a Server/Workstation part, so users who need 12 cores and 24 threads for concurrent workloads are the primary audience. ECC memory support, listed as true, makes the chip suitable for systems where memory errors are unacceptable, such as long-running computations or data-critical workflows. Quad-channel DDR4 with 68.3 GB/s bandwidth supports memory-hungry creation tasks, especially workloads that keep large datasets resident in memory. The 40 PCIe Gen 3 lanes allow multiple accelerators or storage controllers to connect directly to the CPU, which is useful in workstation builds. Gamers should note that the chip has no integrated graphics, so any display output requires a separate GPU. The absence of any gaming benchmark in the record means no gaming performance level is quantified here. Office tasks can run on the 12-core/24-thread arrangement, but the data set contains no office or productivity benchmarks. In short, the listed specifications point to heavily threaded professional workloads rather than single-thread-sensitive applications.

Power and Thermals

The TDP is 135 W, placing it in a thermal class that demands a cooler designed for high-power Xeon processors. The silicon is manufactured on a 22 nm process with 2,600 million transistors and a die size of 356 mm². Those characteristics, combined with the 12 active cores and a 3.30 GHz boost clock, define the thermal load. The data set does not list package power beyond the 135 W TDP, and it does not name a stock cooler. Because the production status is end-of-life, the original cooling bundle, if any, is not part of the record. A practical installation would pair this chip with a cooling solution appropriate for its 135 W TDP class, but no cooler size or additional wattage figure is in the pack.

FAQ

Q: How many cores and threads does the Intel Xeon E5-1686 v3 have?

A: It has 12 cores and 24 threads.

Q: What socket does it use?

A: It uses Intel Socket 2011-3.

Q: Does it support ECC memory?

A: Yes, ECC memory is supported. The memory support is DDR4 over a quad-channel bus with 68.3 GB/s bandwidth.

Q: Does the processor include integrated graphics?

A: No, the integrated graphics field is null, so on-die graphics are not present.

Q: Can the multiplier be unlocked for overclocking?

A: No, the multiplier is locked; the record shows multiplierUnlocked as false.

Q: Is the processor still in production?

A: No, the production status is end-of-life, and the release date is 2014-09-07.

Platform and Compatibility

The E5-1686 v3 fits Intel Socket 2011-3. Memory support is DDR4, wired as quad-channel, with ECC enabled and a bandwidth rating of 68.3 GB/s. The processor provides PCIe Gen 3 with 40 CPU-only lanes, meaning the expansion capacity is carried directly by the CPU. There is no integrated graphics, so a discrete display adapter is required to drive a monitor. The multiplier is locked, so the platform does not target enthusiast overclocking. The architecture is Haswell, specifically Haswell-EP, and the process node is 22 nm. The production status is end-of-life, and the release date is 2014-09-07. The part number recorded is SR1YB. The data pack does not list chipsets, motherboards, or a successor family, so the upgrade path beyond this socket cannot be derived from this record.

Single-Thread vs Multi-Thread Behavior

Single-thread behavior is tied to the 2.60 GHz base clock and 3.30 GHz boost clock, along with the per-core cache sizes: 64 KB L1 and 256 KB L2. Multi-thread behavior is defined by 12 cores and 24 threads, sharing a 30 MB L3 cache. Because the database has no benchmark scores for this processor, the exact single-thread and multi-thread gap cannot be quantified. The clock range from base to boost is present in the data, but the pack does not state whether boost applies to one core or all cores. With 24 threads and a 30 MB shared L3, the chip is heavily positioned for parallel workloads. For lightly threaded workloads, the 3.30 GHz boost clock is the highest relevant number; for fully threaded workloads, the core/thread count and shared cache are more significant.

How It Compares

The nearestRivals list for the Intel Xeon E5-1686 v3 is empty. As a result, there are no named competing processors, no rival scores, and no deltaPct values to report. The only global comparative field is percentileVsAllCpus, which is 50, placing the CPU at the median of all CPUs in the database. Without nearestRivals, the record cannot support a statement such as “ahead of” or “behind” any specific model. The empty benchmarks array further limits comparison to architectural specifications rather than measured results. In short, the data does not define a direct competitor set for this SKU.
