Analysis: AMD EPYC 7351P vs AMD EPYC 7401P
Where Each One Wins
The benchmark data shows a clean sweep for the AMD EPYC 7401P across every recorded test. The EPYC 7401P wins all eight head-to-head comparisons, with the EPYC 7351P recording zero wins. The largest advantages for the 7401P appear in single-core workloads, particularly in Geekbench single-core where it leads by 7.4%, and in Cinebench R15 single-core where it leads by 7%. Multi-core advantages are consistently around 6.9% in the Cinebench suite, while Geekbench multi-core shows a narrower 1.3% gap.
For workloads that depend on sustained multi-threaded throughput, such as rendering or simulation, the 7401P holds a meaningful but not overwhelming edge. The Cinebench R23 multi-core result shows 23660 against 22135, a 6.9% difference that reflects the extra eight cores available on the 7401P. For lightly threaded tasks, the 7401P also leads, though the margin varies: 7% in Cinebench R15 single-core, 6.9% in both R20 and R23 single-core, and 7.4% in Geekbench single-core.
The EPYC 7351P is not without merit. It carries the same 170 TDP, the same memory bandwidth of 170.6 GB/s, and the same eight-channel DDR4 memory bus. Its higher base clock of 2.40 GHz against 2.00 GHz on the 7401P does not translate into any benchmark victory in the recorded data, but it does mean the 7351P is closer in performance than a simple core-count comparison might suggest. The average benchmark score tells the same story: 5814 for the 7401P versus 5469 for the 7351P, a gap of roughly 6.3% on average.
Both processors sit at the 61st percentile among all CPUs in the database, indicating that despite the 7401P's consistent lead, both parts occupy a similar overall performance tier. The practical takeaway is that the 7401P is the stronger choice in every measured category, while the 7351P remains a viable alternative for configurations that prioritize the same platform features with fewer cores.

Head-to-Head Benchmarks
The Cinebench R15 multi-core test opens the comparison with the EPYC 7401P at 2384 and the EPYC 7351P at 2231, a 6.9% delta. The single-core R15 result follows a similar pattern: 336 against 314, a 7% lead. Moving to Cinebench R20, the multi-core scores are 9937 and 9296, again a 6.9% difference, while single-core shows 1402 versus 1312, also 6.9%.
Cinebench R23 repeats the pattern precisely. Multi-core delivers 23660 for the 7401P and 22135 for the 7351P, a 6.9% gap. Single-core produces 3340 against 3125, another 6.9% margin. The consistency of this delta across three generations of Cinebench suggests the performance difference is structural, tied to the core count and clock behavior of the two parts, rather than workload-specific noise.
Geekbench tells a slightly different story. Multi-core shows 4666 for the 7401P and 4607 for the 7351P, a much narrower 1.3% gap. This smaller margin indicates that Geekbench's multi-core workload does not scale as strongly with the 7401P's additional cores, possibly because the test is less sensitive to core count beyond a certain threshold. Single-core Geekbench, however, shows the largest difference in the entire comparison: 787 versus 733, a 7.4% lead for the 7401P. This is notable because the 7351P has a higher base clock of 2.40 GHz versus 2.00 GHz, yet the 7401P still wins single-core performance in every recorded test.
The overall picture is one of uniform dominance. The 7401P leads in every category, with margins ranging from 1.3% in Geekbench multi-core to 7.4% in Geekbench single-core. The average benchmark score reinforces this: 5814 for the 7401P against 5469 for the 7351P. The 7401P also sits close to the Intel Xeon E-2388G in the database, with a delta of 0.2% in average score (5805 for the rival), while the 7351P's nearest rival is the Intel Xeon W-1290P at 5443, a 0.5% delta.
Specification Differences
The core and thread counts are the most obvious differences. The EPYC 7401P offers 24 cores and 48 threads, while the EPYC 7351P offers 16 cores and 32 threads. Base clocks differ as well: the 7401P runs at 2.00 GHz, the 7351P at 2.40 GHz. Boost clocks are closer, with the 7401P at 3.00 GHz and the 7351P at 2.90 GHz, a 0.10 GHz difference in favor of the 7401P.
Both processors share the same TDP of 170, the same AMD Socket SP3, and the same part family within the EPYC 7001 series. Both are listed as unlocked multipliers, and both have the same part number prefixes from the PS740 and PS735 families respectively. The production status is Active for both, and both were released on the same date, 2017-06-28. Neither processor has a launch MSRP recorded in the database.
Memory specifications are identical: DDR4 support, eight-channel memory bus, 170.6 GB/s memory bandwidth, and ECC support on both. PCIe is Gen 3 for both. Neither processor includes integrated graphics. The market segment is Server/Workstation for both.
Architecture Differences
Both processors belong to the EPYC 7001 series and share the same Zen architecture with the Naples codename. They are built on the same 14 nm process node at GlobalFoundries, with the same transistor count of 4,800 million and the same die size of 213 mm². The cache hierarchy is identical: 96 KB of L1 per core, 512 KB of L2 per core, and 64 MB of shared L3 cache.
There are no architectural differences in the recorded specifications. The two processors differ only in core count, thread count, and clock speeds. The shared architecture means that platform-level features such as memory channels, PCIe generation, and ECC support are identical. The generation field for both is listed as "EPYC (Zen (Naples))", confirming they are from the same silicon family.
The practical consequence is that performance differences between the two parts come down almost entirely to the core count and clock configuration. The 7401P has more cores but a lower base clock, while the 7351P has fewer cores but a higher base clock. The boost clock slightly favors the 7401P, which helps explain its consistent single-core lead despite the 7351P's higher base frequency.
The Verdict
The data points to the AMD EPYC 7401P as the stronger processor in every measured benchmark. It wins all eight head-to-head comparisons, with advantages ranging from 1.3% in Geekbench multi-core to 7.4% in Geekbench single-core. The Cinebench suite shows a uniform 6.9% lead across R15, R20, and R23 in both single-core and multi-core tests. The average benchmark score confirms the overall picture: 5814 for the 7401P versus 5469 for the 7351P.
For workloads that scale with core count, such as multi-threaded rendering or scientific computing, the 7401P's 24 cores and 48 threads provide a clear advantage over the 7351P's 16 cores and 32 threads. For single-threaded tasks, the 7401P also leads, despite the 7351P's higher base clock, thanks to its 3.00 GHz boost clock and the measured results.
The EPYC 7351P is not a poor performer. It shares the same platform features, including eight-channel DDR4 memory, 170.6 GB/s bandwidth, ECC support, and PCIe Gen 3. It also runs at a higher base clock, which may benefit certain sustained workloads that do not boost. However, in the recorded benchmarks, it does not win a single test.
Buyers who need maximum performance across both single-threaded and multi-threaded workloads should choose the EPYC 7401P. Buyers who are constrained by core licensing or who prefer the higher base clock of the 7351P may still find it adequate, but the benchmark data shows no scenario where it outperforms the 7401P. The verdict is straightforward: the EPYC 7401P is the superior part in this comparison.
