AMD Ryzen 7 3800XT vs Intel Xeon E-2286G Comparison

Head-to-Head Benchmarks

The recorded head-to-head data shows a clean sweep for the AMD Ryzen 7 3800XT across every shared benchmark. In Cinebench R15 multi-core, the AMD part scores 2230 against 1198 for the Intel Xeon E-2286G, a delta of 46.3% in favor of AMD. This is the largest gap in the comparison and reflects the AMD processor's additional cores and threads. The single-core Cinebench R15 result is closer but still decisive: 219 for the Ryzen 7 3800XT versus 168 for the Xeon, a 23.3% advantage. That margin indicates a substantial per-thread performance lead for the Zen 2 architecture in this legacy rendering workload.

Geekbench results follow the same pattern. The multi-core test shows 8561 for AMD against 6651 for Intel, a 22.3% difference. The single-core Geekbench score narrows to 1773 versus 1598, a 9.9% gap. While the single-core advantage is smaller than the multi-core one, it still represents a meaningful lead for the Ryzen part in lightly threaded tasks. Across all four head-to-head tests, the AMD Ryzen 7 3800XT wins every round, with zero wins recorded for the Intel Xeon E-2286G.

Interpreting these numbers in context, the Xeon E-2286G's average benchmark score of 3610 places it within 0.1% of the Intel Xeon E5-2678 v3 and 0.1% behind the AMD Ryzen 7 PRO 1700. Its closest rival, the Intel Xeon E-2276G, sits just 0.1% higher at 3614. The Ryzen 7 3800XT, with an average score of 3515, sits 0.1% behind the Intel Atom x7213RE and 0.3% behind the Intel Core i3-12300T, while leading the Intel Xeon E-2176G by 0.4%. Both processors occupy the same 55th percentile among all CPUs in the database, meaning the head-to-head deltas are more informative than their overall percentile ranking.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon E-2286G is built on the Coffee Lake architecture, specifically the Coffee Lake-S WS codename, using a 14 nm process at Intel's own foundry. It packs 6 cores and 12 threads, with a base clock of 4.00 GHz and a boost clock of 4.90 GHz. The AMD Ryzen 7 3800XT uses the Zen 2 architecture under the Matisse 2 codename, fabricated on a 7 nm process by TSMC, and offers 8 cores and 16 threads with a 3.80 GHz base clock and 4.70 GHz boost. The AMD part's process node advantage allows a higher transistor density: 3,800 million transistors on a 74 mm² die, compared to the Intel die size of 154 mm² (transistor count not recorded for Intel).

Cache hierarchies differ notably. Both share 64 KB of L1 cache per core, but the L2 cache is 256 KB per core on the Intel part versus 512 KB per core on the AMD part. The shared L3 cache is 12 MB on the Xeon E-2286G, while the Ryzen 7 3800XT has 32 MB. That larger L3 pool can reduce memory latency for frequently accessed data, which may contribute to the AMD part's single-core lead in Geekbench.

Memory bandwidth also favors AMD: 51.2 GB/s versus 42.7 GB/s for Intel, both using dual-channel DDR4. The AMD processor supports PCIe Gen 4, while the Intel part is limited to Gen 3 with 16 lanes from the CPU only. ECC memory support is present on the Xeon but absent on the Ryzen, a notable distinction for workstation reliability. The Xeon includes integrated graphics, specifically HD Graphics P630, while the Ryzen 7 3800XT has no integrated graphics at all. The Xeon's market segment is Server/Workstation, and it is end-of-life, whereas the Ryzen 7 3800XT is an active Desktop part. The Intel chip's multiplier is locked; the AMD chip's multiplier is unlocked, enabling overclocking.

The Verdict

The benchmark data points to the AMD Ryzen 7 3800XT as the stronger performer in every measured category. Its multi-core advantage of 46.3% in Cinebench R15 and 22.3% in Geekbench makes it the clear choice for threaded workloads such as rendering, encoding, or compilation. The single-core lead, while smaller, is still consistent: 23.3% in Cinebench R15 and 9.9% in Geekbench. Users who prioritize raw compute throughput should select the Ryzen 7 3800XT.

However, the Intel Xeon E-2286G retains relevance for specific use cases. It supports ECC memory, a feature absent on the Ryzen part, which matters for data integrity in workstation or server environments. It also includes integrated graphics, eliminating the need for a discrete GPU in basic display scenarios. Its market segment is Server/Workstation, and it fits the Intel Socket 1151 platform, whereas the Ryzen uses AMD Socket AM4. The Xeon's launch MSRP was $450, while the Ryzen's was $399, but the Xeon is now end-of-life, and the Ryzen remains active.

For a desktop user building a high-performance system with no ECC requirement, the Ryzen 7 3800XT is the better fit, offering more cores, more threads, faster memory bandwidth, PCIe Gen 4, and superior benchmark results. For a workstation buyer who needs ECC validation and integrated graphics, the Xeon E-2286G is the only option of the two. The data does not support choosing the Xeon on performance grounds alone; every recorded benchmark favors AMD.

Both processors share the same L1 cache size of 64 KB per core, dual-channel DDR4 memory support, and identical 55th percentile ranking among all CPUs in the database. The AMD part's average benchmark score of 3515 trails the Intel part's 3610 by roughly 2.6%, yet the head-to-head tests show AMD winning every shared workload, a discrepancy explained by the different benchmark suites recorded for each processor. The Intel Xeon E-2286G has no 3DMark results in the database, while the AMD Ryzen 7 3800XT has six, ranging from 748 in single-thread to 6307 in 16-thread and 6294 in max-thread tests.
