AMD Ryzen 7 3800XT vs Intel Xeon E-2186G Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the AMD Ryzen 7 3800XT across every shared benchmark. In the four head-to-head comparisons available, the AMD processor wins all four, with the largest margin appearing in multi-threaded rendering. The Cinebench R15 multi-core test shows the Ryzen 7 3800XT scoring 2230 against the Xeon E-2186G’s 1158, a 92.6% advantage. This is not a marginal lead; it is nearly double the output, driven primarily by the AMD part’s additional two cores and four threads.

Single-core performance also favors AMD, though by a narrower margin. In Cinebench R15 single-core, the Ryzen 7 3800XT records 219 versus the Xeon’s 163, a 34.4% delta. The Geekbench single-core test confirms the trend, with the AMD chip scoring 1773 against 1550, a 14.4% lead. These results indicate that the Zen 2 architecture, despite running on a 7 nm process versus Intel’s 14 nm, delivers superior per-thread performance in this comparison.

The multi-core Geekbench result reinforces the pattern. The Ryzen 7 3800XT posts 8561, while the Xeon E-2186G manages 6204, a 38% delta. This gap is smaller than the Cinebench R15 multi-core difference, but still substantial. The data suggests that the AMD processor’s 8-core, 16-thread configuration scales better under threaded workloads than the Xeon’s 6-core, 12-thread setup. The Xeon’s higher TDP of 95 watts does not translate into a performance advantage here; in fact, the Ryzen 7 3800XT, rated at 105 watts, produces far higher scores across the board.

It is notably the Xeon E-2186G has no benchmark wins in this head-to-head set. Every recorded test, from single-thread to multi-thread, lands in favor of the AMD part. The average benchmark score for the Ryzen 7 3800XT is 3515, with a percentile rank of 55 among all CPUs. The Xeon E-2186G averages 3462, ranking at the 54th percentile. These aggregate figures are close, but the head-to-head deltas reveal that the Ryzen 7 3800XT is the stronger performer in every direct comparison available.

Where Each One Wins

The AMD Ryzen 7 3800XT wins in every workload category represented by the benchmarks. For multi-threaded tasks such as video rendering, 3D modeling, or software compilation, the Cinebench R15 multi-core score of 2230 versus 1158 gives the AMD chip a clear 92.6% advantage. Similarly, Geekbench multi-core shows a 38% lead, meaning applications that utilize all cores will see significantly better throughput on the Ryzen 7 3800XT.

For single-threaded work, the Ryzen 7 3800XT also leads, but the margin is smaller. The Cinebench R15 single-core score of 219 versus 163 (34.4% delta) and Geekbench single-core of 1773 versus 1550 (14.4% delta) indicate that the AMD processor is faster even when only one core is active. This matters for legacy software, spreadsheet tasks, or lightly threaded games where clock speed and IPC (instructions per clock) dominate.

The Xeon E-2186G, despite its 6-core, 12-thread design, does not win any recorded benchmark. Its strengths lie elsewhere: it supports ECC memory, includes integrated HD Graphics P630, and targets the server/workstation segment. For users who require error-correcting memory or a built-in GPU for basic display output, the Xeon offers features the Ryzen 7 3800XT lacks. However, in pure compute performance, the data shows no scenario where the Xeon outperforms the AMD part.

The Ryzen 7 3800XT also holds an advantage in memory bandwidth, with a recorded 51.2 GB/s versus the Xeon’s 42.7 GB/s. This contributes to its superior multi-threaded scores, as memory-bound workloads benefit from the higher throughput. The AMD chip’s larger L3 cache (32 MB versus 12 MB shared) further explains its lead in both single and multi-threaded tests.

Specification Differences

The two processors diverge on several core specifications. The Ryzen 7 3800XT uses 8 cores and 16 threads, while the Xeon E-2186G uses 6 cores and 12 threads. Both share the same base clock of 3.80 GHz and boost clock of 4.70 GHz, but their thermal design power differs: the AMD chip is rated at 105 watts, the Intel chip at 95 watts.

Memory bandwidth is another distinction. The Ryzen 7 3800XT records 51.2 GB/s, while the Xeon E-2186G records 42.7 GB/s. Both support dual-channel DDR4, but the AMD part delivers higher throughput. ECC memory support is exclusive to the Xeon; the Ryzen 7 3800XT does not support it.

PCIe generation also differs. The AMD processor supports PCIe Gen 4, while the Intel Xeon supports PCIe Gen 3 with 16 lanes (CPU only). The Xeon includes integrated HD Graphics P630, whereas the Ryzen 7 3800XT has no integrated graphics. The socket types are different as well: AMD Socket AM4 for the Ryzen, Intel Socket 1151 for the Xeon.

Production status and release dates vary. The Ryzen 7 3800XT is listed as Active, released on 2020-07-06. The Xeon E-2186G is End-of-life, released on 2018-05-30. The Ryzen has an unlocked multiplier, while the Xeon is locked. The launch MSRP for the AMD part is $399, and for the Intel part it is $506.

Architecture Differences

The architectural divide is significant. The Ryzen 7 3800XT is built on TSMC’s 7 nm process, using the Zen 2 architecture with the codename Matisse 2. It contains 3,800 million transistors on a die size of 74 mm². In contrast, the Xeon E-2186G uses Intel’s 14 nm process, based on the Coffee Lake architecture with the codename Coffee Lake-S WS. Its die size is 154 mm², and no transistor count is recorded.

Cache hierarchies differ notably. The Ryzen 7 3800XT provides 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 32 MB of L3 cache. The Xeon E-2186G offers 64 KB of L1 per core, 256 KB of L2 per core, and 12 MB of shared L3. The AMD chip’s larger L3 cache is a major factor in its benchmark superiority, especially in multi-threaded tests.

Feature-wise, the Ryzen 7 3800XT supports PCIe Gen 4, enabling faster storage and GPU bandwidth. The Xeon E-2186G is limited to PCIe Gen 3 with 16 lanes from the CPU. The Xeon compensates with ECC memory support and integrated HD Graphics P630, making it suitable for entry-level workstations where a discrete GPU is unnecessary. The AMD part has no integrated graphics, requiring a separate GPU for display output.

The process node difference is stark: 7 nm versus 14 nm. This explains why the Ryzen 7 3800XT achieves higher performance despite a higher TDP (105 versus 95 watts). The smaller node allows more transistors in a smaller die, improving efficiency and clock-for-clock performance. The Xeon’s larger 154 mm² die on 14 nm limits its ability to compete on raw compute.

The Verdict

The data is unambiguous. The AMD Ryzen 7 3800XT outperforms the Intel Xeon E-2186G in every recorded benchmark. For users prioritizing multi-threaded compute, the Ryzen 7 3800XT is the clear choice, with a 92.6% lead in Cinebench R15 multi-core and a 38% lead in Geekbench multi-core. Single-threaded workloads also favor AMD, with deltas of 34.4% and 14.4% in the two single-core tests. The Ryzen 7 3800XT’s higher memory bandwidth (51.2 GB/s versus 42.7 GB/s) and larger L3 cache (32 MB versus 12 MB) support these results.

The Xeon E-2186G is not without merit, but its strengths are outside raw performance. It supports ECC memory, includes integrated graphics, and has a lower TDP of 95 watts. These features suit a server or workstation environment where data integrity and basic display output matter more than peak compute. Its end-of-life status and older 14 nm architecture place it at a disadvantage versus the active, 7 nm Ryzen part.

Who should pick which? If the workload demands maximum CPU throughput, the Ryzen 7 3800XT wins outright. If the system requires ECC memory or an integrated GPU, the Xeon E-2186G is the only option from this pair. The Ryzen 7 3800XT also offers an unlocked multiplier and PCIe Gen 4 support, adding flexibility for overclocking and modern peripherals. The Xeon’s locked multiplier and PCIe Gen 3 limit its upgrade path. Based on the recorded data, the AMD Ryzen 7 3800XT is the superior processor for almost all compute scenarios.
