AMD EPYC 7351P vs AMD EPYC 7F32 Comparison

The AMD EPYC 7F32 and AMD EPYC 7351P are both server processors on the AMD Socket SP3 platform, but they come from different generations. The 7F32 is a Zen 2 part with a 7 nm process, while the 7351P is a Zen part on 14 nm. The head-to-head benchmark data in the database shows a consistent winner across all Cinebench tests.

Head-to-Head Benchmarks

The recorded head-to-head results cover six Cinebench workloads, and the AMD EPYC 7351P wins every single one. The deltas are remarkably uniform, with the 7F32 trailing by roughly 11% in each test. In Cinebench R15 multi-core, the 7F32 scores 1987 against the 7351P's 2231, a deficit of 10.9%. The single-core R15 test shows a similar gap: 280 versus 314, also 10.8% behind. Moving to Cinebench R20, the multi-core scores are 8281 for the 7F32 and 9296 for the 7351P, a 10.9% difference. The R20 single-core test yields 1168 versus 1312, an 11% gap. In Cinebench R23, the multi-core result is 19718 for the 7F32 and 22135 for the 7351P, again 10.9% behind. The R23 single-core test shows 2783 versus 3125, a 10.9% deficit. Across all six tests, the 7351P leads by a margin that never deviates beyond 0.2 percentage points.

This consistency is striking because the two processors have very different specifications. The 7F32 has a base clock of 3.70 GHz and a boost clock of 3.90 GHz, while the 7351P operates at 2.40 GHz base and 2.90 GHz boost. Despite the 7F32's higher clocks, the 7351P delivers higher scores in both multi-core and single-core Cinebench tests. The 7351P also has double the core count: 16 cores and 32 threads versus 8 cores and 16 threads for the 7F32. The single-core advantage is particularly notable, as it suggests that the 7351P's per-core performance in these workloads is superior, even with a lower clock speed. The data does not explain why, but the measured results are unambiguous.

The 7F32 does have a higher average benchmark score in the database, at 5703 versus 5469 for the 7351P. However, that average includes different test sets: the 7F32 has only Cinebench scores, while the 7351P also has Geekbench results (4607 multi-core and 733 single-core). The head-to-head comparison, which uses identical tests, shows the 7351P ahead in every case.

The Verdict

Based strictly on the benchmark data, the AMD EPYC 7351P is the faster processor for Cinebench workloads. It wins all six head-to-head tests by approximately 11%, and it does so with a lower TDP (170 W versus 180 W) and a larger core count. The 7F32 offers newer architecture, a 7 nm process, and higher memory bandwidth (204.8 GB/s versus 170.6 GB/s), but these advantages do not translate into higher Cinebench scores. The 7351P also has an unlocked multiplier, while the 7F32 is locked, which may appeal to users who plan to overclock, though the database does not include overclocking results.

For server deployments where Cinebench-like multi-threaded performance is a priority, the 7351P is the clear choice. Its 16 cores and 32 threads provide a substantial parallel workload advantage, and the measured single-core performance is also higher. The 7F32, with its PCIe Gen 4 support and 128 lanes, may be more attractive for I/O-intensive applications, but the benchmark data does not cover those scenarios. The 7F32 also has a higher launch MSRP of $2100, but the database does not provide a launch price for the 7351P, so no cost comparison is possible.

The verdict is straightforward: the 7351P wins on measured performance. The 7F32 is not without merit, but its strengths lie in features that are not reflected in the Cinebench results.

Architecture Differences

The two processors represent distinct generations of AMD's EPYC line. The 7F32 is based on the Zen 2 architecture, codenamed Rome, and is manufactured on a 7 nm process at TSMC. It integrates 15,200 million transistors across a die size of 4x 74 mm². The 7351P uses the original Zen architecture, codenamed Naples, on a 14 nm process from GlobalFoundries, with 4,800 million transistors on a single 213 mm² die. This generational gap explains several differences in cache and memory design. The 7F32 has a per-core L1 cache of 64 KB, while the 7351P has 96 KB per core. Both have 512 KB of L2 per core. The L3 cache differs more substantially: the 7F32 provides 32 MB per die with a total of 128 MB, while the 7351P has a single 64 MB shared L3 pool.

Memory bandwidth also reflects the newer design. The 7F32 reaches 204.8 GB/s, compared to 170.6 GB/s for the 7351P, though both use eight-channel DDR4. The 7F32 supports PCIe Gen 4 with 128 lanes, whereas the 7351P is limited to PCIe Gen 3. The 7F32 also has a higher TDP at 180 W versus 170 W, despite having half the cores. The 7351P has an unlocked multiplier, while the 7F32 is locked. The release dates show the 7F32 launched in April 2020, while the 7351P came out in June 2017. These architectural differences are significant, but the benchmark data shows that the older, higher-core-count 7351P outperforms the newer 7F32 in all measured Cinebench tests.
