AMD EPYC 7401P vs AMD Ryzen 7 PRO 3700 Comparison

The AMD EPYC 7401P and AMD Ryzen 7 PRO 3700 occupy opposite ends of AMD’s spectrum, yet benchmark results show a surprising outcome. The EPYC 7401P, a 24-core Naples server chip from 2017, defeats the newer 8-core Matisse desktop processor in every single head-to-head test recorded here. Across six Cinebench workloads, the EPYC 7401P wins all of them, with margins ranging from 21.9% to 22.2%. This is not a close contest; it is a systematic sweep driven by core count and memory bandwidth, even though the Ryzen 7 PRO 3700 has far higher clock speeds and a newer architecture.

Head-to-Head Benchmarks

The EPYC 7401P’s dominance is consistent across every benchmark in the head-to-head set. In Cinebench R15 multicore, the EPYC 7401P scores 2384 against the Ryzen 7 PRO 3700’s 1955, a 21.9% advantage. The single-core R15 test tells a similar story: 336 versus 275, a 22.2% lead for the EPYC. That single-core margin is notable because the Ryzen 7 PRO 3700’s boost clock is 4.40 GHz compared to the EPYC’s 3.00 GHz, yet the older Zen architecture still manages to outpace the Zen 2 part in a single-threaded workload.

Moving to Cinebench R20, the pattern holds. The EPYC 7401P scores 9937 multicore versus 8146 for the Ryzen, a 22% delta. In R20 single-core, the EPYC’s 1402 beats the Ryzen’s 1149 by exactly 22%. The R23 results mirror this: multicore 23660 versus 19397 (22% delta), and single-core 3340 versus 2738 (22% delta). The consistency of the 22% margin across three generations of Cinebench suggests a fundamental architectural advantage, not a workload-specific quirk.

The Ryzen 7 PRO 3700’s average benchmark score is 5610, while the EPYC 7401P’s is 5814. The EPYC’s nearest rival list includes the Intel Xeon E-2388G (deltaPct 0.2%), the Intel Xeon W-2175 (0.8%), and the AMD Ryzen Threadripper 2920X (1.5%), all with average scores within 1.5% of the EPYC. The Ryzen 7 PRO 3700’s nearest rivals are the Intel Core i7-12700T (0.1%), Intel Atom x7433RE (0.2%), and Intel Core i9-11900KB (0.4%). Both CPUs sit at the 61st percentile of all CPUs, meaning they are statistically indistinguishable in overall standing despite the head-to-head sweep.

Where Each One Wins

The EPYC 7401P wins everywhere in these benchmarks, but the nature of its victories points to different use cases. Its multicore wins are expected: 24 cores and 48 threads versus 8 cores and 16 threads means the EPYC has triple the thread count. In Cinebench R23 multicore, the EPYC’s 23660 score is 22% higher than the Ryzen’s 19397, a direct consequence of feeding three times as many threads into a heavily parallel workload. This makes the EPYC the clear choice for server workloads, virtualization, or any task that scales with core count.

The single-core results are more surprising. The EPYC 7401P leads in R23 single-core by 22% (3340 versus 2738), even though the Ryzen 7 PRO 3700 has a 46.7% higher boost clock (4.40 GHz versus 3.00 GHz). This suggests the EPYC’s eight-channel memory bus and 170.6 GB/s bandwidth provide a memory latency advantage that offsets its lower clocks, at least in this benchmark suite. The Ryzen 7 PRO 3700, with its dual-channel 51.2 GB/s memory bus, cannot compensate for that bandwidth deficit.

For desktop users, the Ryzen 7 PRO 3700’s 65W TDP and AM4 socket make it a practical choice for single-socket systems, but the data shows it loses every benchmark here. The EPYC 7401P’s 170W TDP and SP3 socket target servers, and its benchmark wins reflect that positioning. There is no benchmark in this dataset where the Ryzen 7 PRO 3700 wins, so its advantage lies outside these tests—likely in ecosystem compatibility or power efficiency, though the data does not quantify those aspects.

Architecture Differences

The two chips are separated by a full architecture generation. The EPYC 7401P uses Zen on a 14nm process from GlobalFoundries, while the Ryzen 7 PRO 3700 uses Zen 2 on a 7nm process from TSMC. The die sizes reflect this: the EPYC’s die is 213 mm² with 4,800 million transistors, whereas the Ryzen’s is a compact 74 mm² with 3,800 million transistors. The Ryzen packs nearly as many transistors into a third of the die area, a signal of the 7nm node’s density advantage.

Cache hierarchies differ substantially. The EPYC 7401P has 96 KB of L1 per core, 512 KB of L2 per core, and 64 MB of shared L3. The Ryzen 7 PRO 3700 has 64 KB L1 per core, 512 KB L2 per core, and 32 MB of L3. The EPYC’s 64 MB L3 is double the Ryzen’s 32 MB, which helps explain its multicore throughput in cache-sensitive workloads.

Memory support is where the gap widens. The EPYC 7401P uses eight-channel DDR4 with 170.6 GB/s bandwidth, and it supports ECC memory. The Ryzen 7 PRO 3700 uses dual-channel DDR4 with 51.2 GB/s bandwidth and does not support ECC. The EPYC’s memory bandwidth is 3.3 times higher, a critical factor for server workloads that stream data. The EPYC also uses PCIe Gen 3, while the Ryzen 7 PRO 3700 uses PCIe Gen 4 with 24 lanes on the CPU, a newer interconnect standard for peripheral devices.

The sockets are incompatible: the EPYC 7401P uses AMD Socket SP3, and the Ryzen 7 PRO 3700 uses AMD Socket AM4. The EPYC is marked as Server/Workstation, while the Ryzen is Desktop. Both have unlocked multipliers and are marked as Active in production, but their release dates differ: the EPYC launched on 2017-06-28, and the Ryzen on 2019-09-29.

The data shows a clear hierarchy: the EPYC 7401P dominates this benchmark set, but the Ryzen 7 PRO 3700 remains a relevant desktop part for its lower TDP and newer PCIe standard. Both processors hold the same 61st percentile ranking, and their average benchmark scores are close—5814 versus 5610—but the head-to-head results leave no ambiguity about which one performs better in Cinebench.
