The Intel Xeon Gold 5120 is a 14-core, 28-thread server processor that ServeTheHome reviewed in 2018. In that review, it delivered results that depended strongly on the workload, while showing only small differences from nearby 14-core Gold models. The findings are useful as a historical comparison—not as a current buying recommendation.

How ServeTheHome tested the processor
The core CPU tests used a single-socket Supermicro X11SPH-nCTF motherboard with six 16 GB Micron DDR4-2400 RDIMMs, for 96 GB of memory. Storage included an Intel DC S3710 400 GB SSD and a Supermicro 32 GB SATADOM. The article said the system could expand to 768 GB.

The author expected many real deployments to use dual-socket systems, but ran single-socket tests first to build results quickly. That distinction matters: these results describe the tested configuration, not every server built around the processor.
The review’s Linux-Bench and Linux-Bench2 suite included Linux kernel compilation, c-ray rendering, 7-Zip compression, NAMD, Sysbench CPU, OpenSSL sign and verify, UnixBench Dhrystone and Whetstone, GROMACS, and chess. ServeTheHome described the test steps as controlled and consistent in a data-center environment. It also cautioned that its dataset then focused on pre-Spectre/Meltdown results; later Ubuntu 18.04 testing was expected to reflect mitigations and software tuning. The review’s test setup and caveats.
Rank #2
What the 2018 benchmark results showed
The Gold 5120’s relative position changed with the workload. ServeTheHome placed it around the middle of its Linux kernel compilation comparison. In c-ray, the single-socket 5120 approached a dual Xeon Silver 4108 configuration; in 7-Zip, some high-core-count embedded processors outperformed it. The review also reported close results among the Gold 5120, Gold 5119T, and Gold 5117, with the 5120 generally showing small gains over the 5117 consistent with its higher clocks.
These are comparisons from the specific 2018 configurations and software in the review. The searchable article text does not provide the chart values, so exact scores or percentage differences cannot be stated reliably here. Its AMD comparisons also depend on workload and architecture, rather than establishing a single universal ranking.
Rank #3
Power readings: system measurements, not CPU-only consumption
ServeTheHome reported the following readings for its test system in 2018:
| Test condition | Reported reading |
|---|---|
| Idle | 71 W |
| 70% load | 124 W |
| 100% load | 161 W |
| Peak | 165 W |
The readings came from a 208 V Schneider Electric/APC PDU at 17.7 °C and 72% relative humidity, with environmental variation noted by the reviewer. They are test-system readings, not measurements of power drawn by the processor alone, and should not be confused with the CPU’s stated 105 W TDP. ServeTheHome’s power test context.

In 2018, Patrick Kennedy described the Gold 5120 as a low-power option for its target segment, combining 14 cores with single-core turbo above 3 GHz. He questioned the value of having several Intel SKUs—particularly the Gold 5117 and 5119T—that appeared similar in specification and performance. The review also noted that some AMD EPYC processors offered more cores, memory bandwidth or channels, and platform I/O, while power was a countervailing factor.
That was the author’s assessment of the 2018 market and test results. The review does not establish today’s relative value, pricing, availability, compatible motherboard supply, or application-level performance. A present-day decision would need current platform support and workload-specific testing, rather than relying on these historical rankings.

What to take away from the benchmarks
- The Gold 5120’s 14-core, 28-thread specification and 105 W TDP are the figures ServeTheHome reported in its 2018 review.
- Its benchmark standing was workload-specific; kernel compilation, rendering, and compression did not produce the same comparisons.
- Neighboring Gold 5100-series models were close enough in the tested workloads that the review found limited differentiation.
- Power results describe the complete test system and its measurement conditions, not processor-only draw.
- The article is useful for understanding a historical comparison, but cannot answer whether the processor is a good-value purchase now.
