In a dual-processor HPE ProLiant DL380 Gen9, two Xeon E5-2695 v4 CPUs provide 36 cores and 72 threads in total. HPE-sponsored SPEC results for this server and processor combination, published in April 2016, report SPECint2006 of 67.7 and SPECfp_rate2006 of 1,000. ServeTheHome’s 2016 testing also found strong results in 7-Zip compression and NAMD molecular modeling, while noting that multi-threaded scores varied much more than single-threaded ones. These are period benchmarks, not a current comparison with newer servers.
What the benchmarks show
The available results cover two different kinds of evidence: HPE-sponsored SPEC scores for the DL380 Gen9 and ServeTheHome’s workload tests on a particular system configuration. The SPEC scores are numerical; ServeTheHome’s reported findings here are qualitative rather than specific scores.
| Benchmark | Reported result | Configuration and source |
|---|---|---|
| SPECint2006 | 67.7 | Hewlett Packard Enterprise-sponsored result for the ProLiant DL380 Gen9 with Xeon E5-2695 v4 processors; April 2016. The record also reports SPECint_base2006 of 65.8. |
| SPECfp_rate2006 | 1,000 | Hewlett Packard Enterprise-sponsored result for the ProLiant DL380 Gen9 with Xeon E5-2695 v4 processors; April 2016. This record specifies 512 GB of DDR4-2400 memory and a 400 GB SAS SSD. Its SPECfp_rate_base2006 score is 971. |
| 7-Zip compression | Described as excellent in the dual-CPU test; no numerical score stated here | ServeTheHome test published April 18, 2016. |
| NAMD molecular modeling | Described as very good in the dual-CPU test; no numerical score stated here | ServeTheHome test published April 18, 2016. |
| Sysbench CPU and OpenSSL sign/verify | Included in the test suite; no numerical result stated here | ServeTheHome test published April 18, 2016. |
SPECint2006 and SPECfp_rate2006 represent different benchmark measures; they should not be read as competing scores or as direct measures of every server workload. The separate base scores are also distinct metrics, so compare like with like when using SPEC results.
ServeTheHome test configuration
ServeTheHome tested two E5-2695 v4 processors in an HPE ProLiant DL380 Gen9. Each processor has 18 cores and 36 threads, making the system a 36-core, 72-thread configuration. The test platform used Ubuntu 14.04.3 LTS and 64 GB of Samsung DDR4-2400 ECC registered DIMM (RDIMM) memory in four 16 GB modules.

- Storage: one Intel DC S3700 400 GB SSD and four Intel DC P3600 800 GB SSDs.
- Workloads: 7-Zip compression, NAMD molecular modeling, Sysbench CPU, and OpenSSL sign/verify.
- Reported pattern: single-thread results clustered relatively tightly, while multi-thread results showed a wider spread.
That test configuration differs from the SPEC floating-point record, which specifies 512 GB of memory and a 400 GB SAS SSD. Results from the two sources therefore describe different configurations and test methods; they are not a controlled head-to-head comparison.
How to interpret performance for your workload
Parallel throughput
The 18 cores per processor make the E5-2695 v4 most compelling when software can keep many cores busy: examples include parallelized compute, virtualization with multiple active workloads, and suitably configured scientific or media tasks. The strong qualitative descriptions for compression and NAMD are consistent with that use, but the cited test summary does not provide numerical scores for those workloads.
#1 Best Overall
- Intel Xeon E5-2695 v4 SR2J1 Processor
- Processor Base Frequency: 2.10 GHz
- Cache: 45 MB Intel Smart Cache
- Bus Speed: 9.6 GT/s
- Sockets Supported: FCLGA2011-3
Single-thread responsiveness
The processor’s base clock is 2.1 GHz, with turbo frequencies up to 3.3 GHz. A high total core count does not by itself establish how quickly a lightly threaded task will finish; latency-sensitive or lightly threaded software depends more on its active-core behavior and other system factors. ServeTheHome’s observation that single-thread scores clustered tightly is not a numerical estimate of performance for a particular application.
Memory, storage, and system effects
Benchmark results belong to the full test configuration, not just the CPU. Memory capacity and population, storage, firmware, operating system, cooling, and power limits can affect outcomes. In particular, the 64 GB ServeTheHome system and the 512 GB SPECfp_rate system should not be treated as equivalent memory configurations.
Is the E5-2695 v4 a suitable DL380 Gen9 upgrade?
HPE lists the E5-2695 v4 as an optional processor for the DL380 Gen9. Its listed specifications are 18 cores, 2.1 GHz, 45 MB L3 cache, 120 W, 9.6 GT/s QPI, and DDR4-2400 support; HPE part number is 835615-001. Intel’s product specification likewise identifies the model as a 2.10 GHz processor with 45 MB of cache.
For a supported DL380 Gen9 configuration, it is a plausible upgrade when the goal is more parallel CPU capacity and the server’s workload can use additional cores. The benchmark evidence does not establish a universal improvement for every DL380 Gen9 owner, nor does it compare one E5-2695 v4 against two. Before buying, confirm the exact system configuration and processor support with HPE documentation, and account for the cooling and power requirements of the installed CPUs.

Benchmark context and limits
ServeTheHome published its review on April 18, 2016, and the cited SPEC records give April 2016 test dates. Those results are useful as historical measurements of the named platform. They do not establish how the processor ranks against current CPUs, and no live price or stock figure is included here. The SPEC results are sponsored by HPE, a detail worth considering when comparing them with results from other vendors or test conditions.
