AMD EPYC 7351P vs AMD Ryzen 7 PRO 3700 Comparison

The AMD EPYC 7351P is the clear performance winner in every head-to-head benchmark, but the AMD Ryzen 7 PRO 3700 is not a straightforward defeat. The EPYC 7351P leads by a consistent 12.4% margin across all Cinebench tests, a pattern that reflects its doubled core count and server-class architecture. However, both processors sit at the 61st percentile among all CPUs, and their average benchmark scores are remarkably close—5610 for the Ryzen against 5469 for the EPYC—meaning the real decision hinges on workload type, platform features, and efficiency rather than raw dominance.

Head-to-Head Benchmarks

The EPYC 7351P wins all six recorded benchmarks, and every win is by the same 12.4% delta. In Cinebench R15 multi-core, the EPYC scores 2231 against the Ryzen's 1955, a gap that persists in single-core at 314 versus 275. Moving to Cinebench R20, the EPYC posts 9296 multi-core and 1312 single-core, while the Ryzen manages 8146 and 1149 respectively. The latest Cinebench R23 shows the same story: 22135 multi-core for the EPYC versus 19397 for the Ryzen, and 3125 single-core versus 2738.

This uniformity is striking. A 12.4% advantage in both single-threaded and multi-threaded tests suggests the EPYC's higher per-core clock efficiency, despite its lower base and boost clocks, is not the deciding factor. Instead, the EPYC's 16 cores and 32 threads simply outmuscle the Ryzen's 8 cores and 16 threads in multi-core workloads, while its superior single-core score indicates better sustained clock behavior under test conditions. The Ryzen 7 PRO 3700, with a 4.40 GHz boost clock versus the EPYC's 2.90 GHz, would normally be expected to win single-core tests; the data contradicts that expectation outright.

The average benchmark scores reinforce the narrow overall gap. The Ryzen's average of 5610 is only 2.6% higher than the EPYC's 5469, despite losing every head-to-head test. This discrepancy arises because the EPYC's additional Geekbench results—4607 multi-core and 733 single-core—drag its average down; the Ryzen has no Geekbench scores in the dataset. When comparing to their nearest rivals, the Ryzen sits 0.1% above the Intel Core i7-12700T and 0.2% above the Intel Atom x7433RE, while the EPYC is 0.5% above the Intel Xeon W-1290P and 0.8% above the AMD Ryzen Threadripper 1920. Both CPUs also trade blows with the Intel Celeron G6900, with the Ryzen 0.9% ahead and the EPYC 1.7% behind.

The Verdict

Choose the AMD EPYC 7351P if your priority is maximum multi-threaded throughput and you have the platform to support it. The data is unambiguous: it wins every Cinebench test by 12.4%, and its 16-core/32-thread configuration doubles the Ryzen's thread count. Its eight-channel memory bus with 170.6 GB/s bandwidth and ECC memory support make it the only option here for server or workstation reliability workloads. The EPYC's 61st percentile ranking matches the Ryzen, but its average score of 5469 is lower—so this is not a universally faster chip, just one that dominates the specific benchmarks tested.

Pick the AMD Ryzen 7 PRO 3700 if you need a lower-power desktop processor with a modern socket and faster boost clock. Its 65W TDP is less than half the EPYC's 170W, and its AM4 socket with PCIe Gen 4 support offers a more current platform path. The Ryzen's 4.40 GHz boost clock and 7nm process node from TSMC suggest better per-watt performance, though no power efficiency numbers are in the data. Its average benchmark score of 5610 surpasses the EPYC's 5469, indicating that in tests outside the Cinebench suite, it may perform competitively or better—but the provided head-to-head data does not capture that.

Neither chip has a launch MSRP listed, so pricing cannot factor into this verdict. Production status is active for both, meaning availability is not a differentiator.

Where Each One Wins

The EPYC 7351P wins in every measured benchmark category. For multi-threaded rendering tasks, Cinebench R23 multi-core shows a 2738-point lead. For single-threaded responsiveness, the EPYC's 3125 score in Cinebench R23 single-core beats the Ryzen's 2738 by 387 points. The same pattern holds in R15 and R20, with the EPYC leading by 276 and 1150 points in multi-core, and 39 and 163 points in single-core, respectively.

The Ryzen 7 PRO 3700 wins in platform attributes that matter outside raw benchmark scores. Its 7nm process node (versus 14nm for the EPYC) and 74 mm² die size (versus 213 mm²) indicate a more compact, likely more efficient design. Its 65W TDP is 105W lower than the EPYC's 170W, making it viable for standard desktop builds. The Ryzen's 4.40 GHz boost clock is 1.50 GHz higher than the EPYC's 2.90 GHz, which could translate to better burst performance in lightly threaded applications—though the benchmark data contradicts this for Cinebench. The Ryzen also supports PCIe Gen 4 with 24 CPU lanes, while the EPYC is limited to PCIe Gen 3.

Memory configuration further separates them. The EPYC's eight-channel DDR4 bus with 170.6 GB/s bandwidth is over three times the Ryzen's dual-channel 51.2 GB/s. The EPYC also supports ECC memory, which the Ryzen does not. For memory-intensive server workloads, this is a decisive advantage; for desktop use, the Ryzen's simpler dual-channel setup is more than adequate.

Architecture Differences

The two CPUs come from different AMD generations and foundries. The Ryzen 7 PRO 3700 uses Zen 2 architecture on a 7nm process node from TSMC, with a codename of Matisse and a die size of 74 mm² containing 3,800 million transistors. The EPYC 7351P uses the original Zen architecture on a 14nm process node from GlobalFoundries, with a codename of Naples and a die size of 213 mm² containing 4,800 million transistors.

Cache layouts diverge significantly. The Ryzen has 64 KB of L1 cache per core and 512 KB of L2 per core, with 32 MB of shared L3 cache. The EPYC has 96 KB of L1 per core and 512 KB of L2 per core, but doubles the shared L3 to 64 MB. This larger L3 cache, combined with more cores, supports the EPYC's server-oriented data handling.

PCIe support also marks a generational split. The Ryzen offers PCIe Gen 4 with 24 CPU lanes, while the EPYC is limited to PCIe Gen 3. Both lack integrated graphics, so a discrete GPU is required for display output. The Ryzen's multiplier is unlocked, as is the EPYC's, allowing overclocking on both—though the EPYC's server platform may restrict practical overclocking.

Specification Differences

The most visible difference is core count: 8 cores/16 threads for the Ryzen versus 16 cores/32 threads for the EPYC. Clock speeds favor the Ryzen, with a 3.60 GHz base and 4.40 GHz boost versus the EPYC's 2.40 GHz base and 2.90 GHz boost. Thermal design power is dramatically different: the Ryzen draws 65W, the EPYC 170W.

Sockets and platforms are incompatible: the Ryzen uses AMD Socket AM4, while the EPYC uses AMD Socket SP3. Memory channels are the next major split—dual-channel for the Ryzen, eight-channel for the EPYC—with corresponding bandwidth of 51.2 GB/s versus 170.6 GB/s. ECC memory support exists only on the EPYC.

Process node and die size differ by generation: 7nm and 74 mm² for the Ryzen, 14nm and 213 mm² for the EPYC. Transistor counts are 3,800 million for the Ryzen and 4,800 million for the EPYC. Release dates are separated by over two years: the Ryzen launched on September 29, 2019, while the EPYC launched on June 28, 2017. The Ryzen is part of the 3000 series, the EPYC part of the 7001 series. Part numbers differ as well: 100-000000073 for the Ryzen and PS735PBEVGPAF for the EPYC.
