Intel Xeon E-2186G

The Intel Xeon E-2186G is a 6-core, 12-thread processor built on the Coffee Lake architecture (codename Coffee Lake-S WS) for the Server/Workstation segment. It runs at a base clock of 3.80 GHz and boosts to 4.70 GHz, with a 95W TDP and a 14nm process. It supports DDR4 memory in dual-channel mode with ECC, includes HD Graphics P630, and uses Intel Socket 1151. The chip is end-of-life, released on May 30, 2018, and carries a launch MSRP of $506. In the benchmark database, it holds a 57th percentile position among all CPUs, with an average benchmark score of 3511. The nearest rivals are all within a fraction of a percent in average score, making this a tightly contested performance tier.

Who Should Consider It

The E-2186G suits builders who need a compact workstation or entry-level server with a strong single-thread response. Its single-core results—166 in Cinebench R15, 694 in R20, 1654 in R23, and 1550 in Geekbench—indicate that everyday tasks like office applications, web development, and light code compilation will feel immediate. For multi-threaded work, the R23 multi-core score of 11717 and Geekbench multi of 6204 show it can handle moderate rendering, video transcoding, and virtual machine hosting that scale to 12 threads. Because ECC memory is supported, it is a fit for environments where memory errors are unacceptable, such as small file servers, database hosts, or financial modeling. However, with only six physical cores and a 57th percentile standing, it is not intended for heavy parallel compute like 3D animation rendering or large-scale scientific simulations. The integrated HD Graphics P630 means a discrete GPU is optional for basic display, which simplifies server builds. This chip is best for users who want a balanced, reliable part with a proven socket and no overclocking ambitions.

Single-Thread vs Multi-Thread Behavior

The benchmark split shows a clear design goal: fast single-thread performance without sacrificing multi-thread scaling. The R23 single-core score of 1654 is close to that of many modern mainstream desktop CPUs, and the Geekbench single-core of 1550 reinforces that impression. Multi-thread performance scales effectively—the R23 multi-core of 11717 is roughly seven times the single-core figure, indicating the six physical cores and twelve threads are well utilized. In practice, this means the E-2186G will feel responsive in day-to-day use, but it will also contribute meaningfully to threaded workloads like video encoding or batch photo processing. The gap between single- and multi-thread scores is typical for a 6-core/12-thread Coffee Lake part; it does not show the extreme multi-thread advantage of higher-core-count Xeons, but it avoids the single-thread penalty common to many server chips. For a mixed workload—say, running a virtual machine while compiling code—the balance is practical and predictable.

Power and Thermals

The 95W TDP places the E-2186G in the mainstream desktop power class. This is not a high-core-count server part with a large power draw; it is a 6-core chip that a capable air cooler can handle. The 14nm process and 154 mm² die size are standard for the Coffee Lake generation. Because it is a Xeon, the thermal design assumes sustained operation in a server chassis, but the 95W figure means it does not demand exotic cooling. A standard tower cooler or a compact liquid cooler will suffice in most workstation cases. The integrated HD Graphics P630 adds a small amount of heat, but it is generally negligible. Users building a quiet workstation should have no trouble with this chip's thermals, provided the case has adequate airflow and the cooler is properly mounted.

How It Compares

The nearest rivals, based on average benchmark score, are all within a fraction of a percent of the E-2186G. The Intel Xeon D-1732TE averages 3504, just 0.2% behind the E-2186G's 3511. That rival is a low-power system-on-chip for networking and edge computing; the E-2186G offers similar average performance but with a higher single-thread ceiling, as reflected in its R23 single-core score of 1654. The Intel Xeon E-2246G, another 6-core Coffee Lake part, scores 3503, also 0.2% behind—essentially a tie. The E-2246G is a direct successor in the same family, so the performance difference is negligible in real workloads. The Intel Xeon E5-1680 v4, a Broadwell-EP part with more cores, scores 3502, 0.3% behind; the E-2186G matches it in average benchmarks despite having fewer cores, thanks to higher clock speeds and a more modern architecture. The only rival that edges ahead is the Intel Core i3-12300, which scores 3528, 0.5% higher than the E-2186G. That modern i3, with its newer architecture, manages to outpace the older Xeon in average score, but the Xeon's ECC support and integrated GPU give it a niche that the i3 cannot fill.

Platform and Compatibility

The E-2186G uses Intel Socket 1151, the same physical socket as many consumer Coffee Lake and Kaby Lake chips. It is built on the Coffee Lake architecture (codename Coffee Lake-S WS) and uses a 14nm process. Memory support is DDR4 in a dual-channel configuration, with a memory bandwidth of 42.7 GB/s. It supports ECC memory, which is a key feature for workstations and servers. PCIe is Gen 3 with 16 lanes from the CPU—enough for a single high-end GPU or a couple of NVMe drives. The integrated HD Graphics P630 provides display output without a discrete GPU, simplifying basic server builds. The cache layout includes 64 KB L1 and 256 KB L2 per core, plus a shared 12 MB L3. Because the product is end-of-life and the socket is mature, there is no forward upgrade path to newer generations; users are limited to other LGA1151 processors already on the market. The part number is SR3WR, and the multiplier is locked, so overclocking is not supported.
