AMD Ryzen Embedded V3C18I vs Intel Xeon E-2186G Comparison

Head-to-Head Benchmarks

The benchmark data leaves no ambiguity: the AMD Ryzen Embedded V3C18I wins every single head-to-head test in the database, six wins to zero for the Intel Xeon E-2186G. The margins are consistent and narrow, all at exactly 2.4% in favor of the AMD part.

Starting with Cinebench R15, the AMD Ryzen Embedded V3C18I scores 1187 in the multicore test against 1158 for the Intel Xeon E-2186G. The single-core result follows the same pattern: 167 for AMD versus 163 for Intel. In both cases, the delta is 2.4%, meaning the AMD chip holds a small but uniform edge across both single-threaded and multi-threaded workloads.

Moving to Cinebench R20, the AMD Ryzen Embedded V3C18I posts 4946 in multicore, while the Intel Xeon E-2186G reaches 4826. The single-core numbers are 698 versus 681. Again, the 2.4% delta applies to both. The consistency of this margin across different benchmark versions suggests a fundamental per-core efficiency advantage rather than a scaling quirk.

Cinebench R23, the most demanding render test in the recorded data, shows the same story. The AMD Ryzen Embedded V3C18I scores 11777 in multicore, and the Intel Xeon E-2186G scores 11492. In single-core, the AMD part reaches 1662 against 1622 for Intel. The 2.4% gap persists without variation.

It is worth remembering the Intel Xeon E-2186G has additional Geekbench scores in the database: 6204 multicore and 1550 single-core. The AMD Ryzen Embedded V3C18I does not have Geekbench entries, so a direct comparison on that test is impossible from the recorded data. However, across all six shared Cinebench tests, the AMD part wins every time with an identical 2.4% margin.

The average benchmark score in the database shows a slightly different picture. The Intel Xeon E-2186G has an average of 3462, while the AMD Ryzen Embedded V3C18I sits at 3406. That difference comes from the Intel part having Geekbench scores included in its average, which drags its overall figure upward relative to the AMD chip. The head-to-head Cinebench results, which are the only directly comparable tests, tell the opposite story.

Percentile rankings place both processors at the 54th percentile among all CPUs in the database, meaning they occupy the same tier of overall performance despite the AMD part winning every shared test.

Where Each One Wins

The recorded benchmark data shows the AMD Ryzen Embedded V3C18I winning in every measured category. There are no wins for the Intel Xeon E-2186G in any of the six head-to-head tests. This includes both single-core and multi-core workloads across three generations of Cinebench (R15, R20, R23).

For single-threaded performance, the AMD Ryzen Embedded V3C18I leads by 2.4% in all three Cinebench versions. This is notable because single-core performance typically depends heavily on clock speed and architectural efficiency. The Intel Xeon E-2186G has a significantly higher boost clock of 4.70 GHz compared to the AMD part's 3.80 GHz boost, yet the AMD chip still manages to edge ahead. This indicates the Zen 3+ architecture achieves higher instructions per clock than the older Coffee Lake design.

For multi-threaded workloads, the same 2.4% margin holds. The AMD Ryzen Embedded V3C18I has 8 cores and 16 threads, while the Intel Xeon E-2186G has 6 cores and 12 threads. The AMD part also has a larger shared L3 cache at 16 MB versus 12 MB. These structural advantages combine with the per-core efficiency to produce a consistent lead.

In practical terms, the AMD Ryzen Embedded V3C18I is the better choice for any workload that stresses the CPU, whether that is rendering, compilation, or general compute. The Intel Xeon E-2186G does not win a single recorded benchmark, so there is no data-driven case for selecting it based on performance alone.

The only area where the Intel part appears favorable in the database is its average benchmark score, which is higher at 3462 versus 3406. However, that figure is inflated by the inclusion of Geekbench results that have no AMD counterpart in the recorded data. When comparing only the tests both CPUs actually ran, the AMD part wins every time.

Architecture Differences

The two processors come from different design philosophies and different manufacturing eras. The Intel Xeon E-2186G is built on the Coffee Lake architecture, specifically the Coffee Lake-S WS variant, using a 14 nm process node fabricated by Intel. The AMD Ryzen Embedded V3C18I uses the Zen 3+ architecture, codenamed Rembrandt, on a 6 nm process node fabricated by TSMC. The process node difference is substantial: 14 nm versus 6 nm.

The Intel part has 6 cores and 12 threads, while the AMD part has 8 cores and 16 threads. The AMD chip therefore offers 33% more cores and threads in the same comparison. The base clock for the Intel Xeon E-2186G is 3.80 GHz with a boost clock of 4.70 GHz. The AMD Ryzen Embedded V3C18I has a base clock of 1900.00 MHz, which translates to 1.90 GHz, and a boost clock of 3.80 GHz. The Intel part has much higher raw clock speeds, but the AMD part still wins on performance due to architectural efficiency.

Cache layouts differ notably. Both have 64 KB of L1 cache per core. The L2 cache is 256 KB per core on the Intel part versus 512 KB per core on the AMD part, giving the AMD chip twice the L2 capacity per core. The shared L3 cache is 12 MB on the Intel Xeon E-2186G and 16 MB on the AMD Ryzen Embedded V3C18I. The AMD part has larger caches at every level beyond L1.

Memory support is another clear split. The Intel Xeon E-2186G supports DDR4 memory over a dual-channel bus with a measured bandwidth of 42.7 GB/s. The AMD Ryzen Embedded V3C18I supports DDR5 memory over a dual-channel bus with 76.8 GB/s of bandwidth. The AMD platform offers 80% more memory bandwidth, which matters for memory-intensive workloads.

Both CPUs support ECC memory, a requirement for many server and workstation applications. The PCIe implementation differs: the Intel part offers Gen 3 with 16 lanes from the CPU, while the AMD part offers Gen 4 with 20 lanes from the CPU. The AMD chip provides both a newer PCIe standard and more lanes.

The Intel Xeon E-2186G includes integrated graphics in the form of HD Graphics P630. The AMD Ryzen Embedded V3C18I has no integrated graphics in the recorded data. This is a meaningful difference for systems that need a display output without a discrete GPU.

The sockets are incompatible: Intel uses Socket 1151, while AMD uses Socket FP7. The Intel part is listed as end-of-life, while the AMD part is active production. The Intel Xeon E-2186G was released on 2018-05-30, and the AMD Ryzen Embedded V3C18I was released on 2022-09-26. The die size for the Intel part is 154 mm², while the AMD die size is not recorded. Transistor counts are not available for either part.

The Verdict

Based strictly on the recorded benchmark data, the AMD Ryzen Embedded V3C18I is the superior processor. It wins all six head-to-head Cinebench tests, covering both single-core and multi-core workloads, with a uniform 2.4% margin. It does this despite having a much lower boost clock of 3.80 GHz compared to 4.70 GHz for the Intel part. The architectural efficiency of Zen 3+ on 6 nm clearly compensates for the clock speed deficit.

The AMD Ryzen Embedded V3C18I also offers more cores, more threads, larger caches, faster memory support, and a newer PCIe standard. The Intel Xeon E-2186G only has advantages in its higher clock speeds, integrated graphics, and a higher average benchmark score that is skewed by Geekbench results not available for the AMD part.

For any compute workload measured in the database, the choice is clear: the AMD Ryzen Embedded V3C18I wins. The Intel Xeon E-2186G should only be considered if a system requires integrated graphics, as the AMD part has none. The Intel part is also end-of-life, while the AMD part remains in active production.

The percentile ranking places both at 54th among all CPUs, indicating they are in the same performance tier. However, within that tier, the AMD part is consistently ahead in every directly comparable test. There is no recorded scenario where the Intel Xeon E-2186G outperforms the AMD Ryzen Embedded V3C18I.
