AMD EPYC 7351P vs Intel Xeon W-2175 Comparison

The Verdict

The benchmark data is unambiguous. The AMD EPYC 7351P wins every single head-to-head benchmark against the Intel Xeon W-2175, taking all six recorded comparisons. Across Cinebench R15, R20, and R23, the AMD part leads by a consistent margin of 9.9 percent in both single-core and multi-core tests. The Intel Xeon W-2175 records zero wins in this matchup. For workloads that rely on Cinebench-style rendering, the EPYC 7351P is the clear choice. However, the Intel part still holds relevance for specific environments. The Xeon W-2175 has a higher boost clock of 4.30 GHz versus 2.90 GHz on the EPYC, which can matter for latency-sensitive tasks not captured in these render benchmarks. The data suggests that if a user prioritizes raw multi-threaded throughput, the EPYC 7351P delivers uniformly better results. If a user needs a workstation CPU with a significantly higher turbo ceiling and is willing to accept lower multi-core scores, the Intel part remains a viable option. The percentile ranking for both processors is identical at 61, indicating they occupy the same overall performance tier among all CPUs in the database.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Xeon W-2175 is built on the Skylake architecture, specifically the Skylake-W codename, using a 14 nm process node manufactured by Intel. It features 14 cores and 28 threads. The AMD EPYC 7351P belongs to the EPYC 7001 series, based on the Zen architecture with the Naples codename, also on a 14 nm node but fabricated by GlobalFoundries. The EPYC packs 16 cores and 32 threads. The die size difference is stark: the Intel chip measures 484 mm², while the AMD chip is only 213 mm². The EPYC integrates 4,800 million transistors, but the database records no transistor count for the Intel part.

Cache layouts diverge considerably. The Xeon W-2175 has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 19.25 MB of shared L3 cache. The EPYC 7351P uses 96 KB of L1 per core, 512 KB of L2 per core, and a much larger 64 MB of shared L3 cache. That 64 MB L3 is more than three times the Intel's shared pool. Memory architecture also differs: the Intel part supports quad-channel DDR4 with a recorded bandwidth of 85.3 GB/s, while the AMD part supports eight-channel DDR4 with 170.6 GB/s of bandwidth, exactly double. PCIe connectivity shows the Intel chip with Gen 3 across 48 lanes (CPU only), whereas the EPYC lists simply Gen 3 without a lane count. The Intel part is marked end-of-life, while the EPYC remains active in production. The EPYC has an unlocked multiplier; the Intel part does not.

Where Each One Wins

The EPYC 7351P wins everywhere the recording shows a benchmark. In multi-core tests, the AMD part's advantage is consistent: 9.9 percent ahead in Cinebench R15, R20, and R23 multi-core. That margin holds for single-core tests as well, with the EPYC ahead by the same 9.9 percent in all three Cinebench single-core variants. The Intel Xeon W-2175 does not win any recorded benchmark against the EPYC. However, the Intel part has strengths that the recorded Cinebench suite does not measure. Its boost clock of 4.30 GHz is 48 percent higher than the EPYC's 2.90 GHz boost. For applications that depend on a single thread reaching maximum frequency, the Intel part could show an advantage in real-world tasks, even though the EPYC scores higher in the synthetic single-core Cinebench tests. The EPYC's eight-channel memory bus and doubled bandwidth of 170.6 GB/s make it better suited for memory-bound workloads such as large database operations or virtualization hosts. The Intel part's 48 PCIe lanes (Gen 3) may appeal to users needing more direct expansion slots for storage or accelerators, although the EPYC's PCIe Gen 3 support is present without a lane count in the data.

For a workstation user running render jobs, the EPYC is the obvious pick. For a user who prioritizes the highest possible turbo frequency and values the Intel platform's specific feature set, the Xeon W-2175 remains a defensible choice, but the recorded data does not show it winning any head-to-head test.

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the AMD EPYC 7351P. In Cinebench R15 multi-core, the EPYC scores 2231 against the Intel's 2010, a 9.9 percent lead. The single-core R15 test shows the same pattern: 314 for the EPYC versus 283 for the Intel, again a 9.9 percent difference. Moving to Cinebench R20, the EPYC scores 9296 in multi-core versus 8379 for the Xeon, and 1312 versus 1182 in single-core. The margin remains exactly 9.9 percent in both. Cinebench R23 continues the trend: the EPYC posts 22135 in multi-core and 3125 in single-core, while the Intel posts 19951 and 2816 respectively. Each of these six comparisons shows a 9.9 percent delta in favor of the AMD part.

The consistency of that 9.9 percent margin across all tests is notable. It suggests that the performance gap is not workload-specific but rather a uniform architectural advantage. The EPYC's extra two cores (16 versus 14) and larger L3 cache (64 MB versus 19.25 MB) likely contribute to the multi-core leads. The single-core lead is more surprising, given the Intel part's much higher boost clock of 4.30 GHz versus 2.90 GHz. Yet the EPYC still wins single-core tests by the same 9.9 percent, indicating that the Zen core's instruction efficiency overcomes the clock disadvantage in these Cinebench tests. The Intel part's zero wins out of six benchmarks is a decisive result.

Additionally, the database lists a Geekbench multi-core score of 4607 and a single-core score of 733 for the EPYC 7351P, but no comparable Geekbench results are recorded for the Xeon W-2175, so a head-to-head comparison for that test cannot be made.
