AMD EPYC 7452 vs AMD EPYC 7542 Comparison

The AMD EPYC 7452 and AMD EPYC 7542 are both 32-core, 64-thread server processors built on the same Zen 2 "Rome" architecture, yet they occupy distinct positions in the EPYC 7002 series lineup. The data shows a remarkably consistent performance relationship between the two, with the EPYC 7452 holding a narrow but uniform advantage across all six Cinebench benchmarks. Both processors achieve the same 66th percentile ranking among all CPUs, and their average benchmark scores differ by less than 1.2%, making these two parts virtually interchangeable in raw throughput terms while differing meaningfully in clock strategy and power allocation.

FAQ

Q: Which processor has a higher base clock speed?

A: The AMD EPYC 7542 has a base clock of 2.90 GHz, while the AMD EPYC 7452 operates at 2.20 GHz. This 0.70 GHz difference represents the most significant specification gap between the two parts.

Q: How do the two processors compare in multi-core Cinebench R23 performance?

A: The AMD EPYC 7452 scores 38,993 points in Cinebench R23 multi-core, while the AMD EPYC 7542 scores 38,555 points. The EPYC 7452 leads by 1.1%, which is a consistent margin across all tested workloads.

Q: Are there any benchmark categories where the AMD EPYC 7542 wins?

A: No. According to the head-to-head benchmark data, the AMD EPYC 7452 wins all six tested benchmarks, with a 1.1% delta in every single test. The EPYC 7542 has zero wins in the comparison.

Q: What is the thermal design power difference between the two chips?

A: The AMD EPYC 7452 has a TDP of 155 watts, while the AMD EPYC 7542 has a TDP of 225 watts. The EPYC 7542 draws 70 watts more power while delivering slightly lower benchmark scores.

Q: Do both processors share the same cache configuration?

A: Yes. Both the AMD EPYC 7452 and AMD EPYC 7542 have identical cache hierarchies: 96 KB of L1 per core, 512 KB of L2 per core, and 128 MB of shared L3 cache.

Q: Which processor has a higher boost clock?

A: The AMD EPYC 7542 has a boost clock of 3.40 GHz, which is 0.05 GHz higher than the AMD EPYC 7452's boost clock of 3.35 GHz. Despite this higher boost frequency, the EPYC 7452 still wins all single-core benchmarks.

Architecture Differences

Both processors are built on the identical Zen 2 architecture with the "Rome" codename, manufactured on a 7 nm process at TSMC. Each chip contains 3,800 million transistors on a 74 mm² die, and both use the AMD Socket SP3 platform. The architecture is fundamentally the same: eight memory channels supporting DDR4 with 204.8 GB/s of memory bandwidth, ECC memory support, and PCIe Gen 4 connectivity. Neither processor has integrated graphics, and both are unlocked for multiplier adjustment.

The core configuration is identical as well — 32 cores and 64 threads on both parts, with the same per-core L1 and L2 cache sizes and the same 128 MB shared L3 cache. The production status for both is listed as active, and both were released on the same date. The part numbers differ (100-000000057 for the EPYC 7452 and 100-000000075 for the EPYC 7542), but the underlying silicon appears to be the same design.

The critical architectural difference lies in clock strategy. The EPYC 7542 is configured with a higher base clock of 2.90 GHz versus 2.20 GHz on the EPYC 7452, and a slightly higher boost clock of 3.40 GHz versus 3.35 GHz. This higher clock configuration on the EPYC 7542 comes at a significant power cost, with TDP rising from 155 watts to 225 watts. The EPYC 7452, by contrast, runs at lower clocks but achieves equal or better benchmark results, suggesting a more efficient operating point.

Head-to-Head Benchmarks

The benchmark results tell a story of remarkable consistency. Across all six Cinebench tests, the AMD EPYC 7452 wins every single one with exactly the same 1.1% margin. In Cinebench R15 multi-core, the EPYC 7452 scores 3,930 against the EPYC 7542's 3,886. The single-core R15 result is 554 versus 548, again favoring the EPYC 7452.

Moving to Cinebench R20, the pattern holds. Multi-core scores are 16,377 for the EPYC 7452 and 16,193 for the EPYC 7542, a difference of 184 points. Single-core R20 shows 2,312 versus 2,286. The largest absolute gap appears in Cinebench R23 multi-core, where the EPYC 7452 scores 38,993 and the EPYC 7542 scores 38,555 — a 438-point spread. Single-core R23 is 5,505 versus 5,443.

What makes this outcome notable is the clock speed inversion. The EPYC 7542 has a 0.70 GHz higher base clock and a 0.05 GHz higher boost clock, yet it loses every benchmark. The EPYC 7452's victory margin is uniform at 1.1%, which suggests the benchmark results are capturing a consistent performance characteristic rather than workload-specific variability. The average benchmark score confirms this: the EPYC 7452 averages 11,279 points across all benchmarks, while the EPYC 7542 averages 11,152 points.

The Verdict

The benchmark data is unambiguous: the AMD EPYC 7452 is the faster processor in every tested workload, despite the EPYC 7542's higher clock speeds. The 1.1% margin is small in absolute terms but completely consistent, appearing in every single-core and multi-core test. The EPYC 7452 achieves this performance with a 70-watt lower TDP (155 watts versus 225 watts), making it the more efficient choice on both performance and power grounds.

For workloads that depend on Cinebench-style rendering performance, the EPYC 7452 is the clear pick. The data shows no scenario where the EPYC 7542's higher clocks translate into a benchmark win. The EPYC 7542's only advantages are its higher base and boost clock specifications, but these do not produce superior results in any measured test.

The EPYC 7542 might appeal to buyers who prioritize clock speed specifications for single-threaded legacy workloads not captured in these benchmarks, but within the tested Cinebench suite, it offers no performance benefit. The EPYC 7452 wins all six benchmarks, has a lower TDP, and maintains the same 66th percentile ranking among all CPUs. The verdict from the data is straightforward: the AMD EPYC 7452 is the better processor in this comparison.

Specification Differences

The two processors differ in exactly four specification fields. The base clock is 2.20 GHz on the EPYC 7452 versus 2.90 GHz on the EPYC 7542. The boost clock is 3.35 GHz on the EPYC 7452 versus 3.40 GHz on the EPYC 7542. The TDP is 155 watts on the EPYC 7452 versus 225 watts on the EPYC 7542. Finally, the part numbers differ: 100-000000057 for the EPYC 7452 and 100-000000075 for the EPYC 7542.

All other specifications are identical: 32 cores, 64 threads, 96 KB L1 per core, 512 KB L2 per core, 128 MB shared L3 cache, DDR4 memory support with eight-channel bus and 204.8 GB/s bandwidth, ECC memory support, PCIe Gen 4, no integrated graphics, 7 nm process node, TSMC foundry, 3,800 million transistors, 74 mm² die size, AMD Socket SP3, Zen 2 architecture, Rome codename, Server/Workstation market segment, active production status, and the same release date.

Where Each One Wins

The AMD EPYC 7452 wins in every benchmark category tested: Cinebench R15 multi-core, Cinebench R15 single-core, Cinebench R20 multi-core, Cinebench R20 single-core, Cinebench R23 multi-core, and Cinebench R23 single-core. This gives it six wins out of six head-to-head comparisons. Its performance advantage is consistent at 1.1% across all tests, and it accomplishes this with a 70-watt lower TDP.

The AMD EPYC 7542 wins no benchmarks in the head-to-head comparison. Its higher base clock of 2.90 GHz and higher boost clock of 3.40 GHz do not translate into superior performance in any tested workload. However, the specification data shows that for applications that operate strictly at base clock frequencies without boost behavior, the EPYC 7542's 2.90 GHz base clock might theoretically provide an advantage, though this is not reflected in the Cinebench results.

For deployment scenarios, the EPYC 7452 is the better choice for multi-threaded rendering workloads, single-threaded responsiveness, and power-constrained environments. The EPYC 7542, with its higher TDP and clock specifications, offers no measured performance benefit in this benchmark suite. The data supports selecting the EPYC 7452 for virtually all use cases where these two processors are being compared.
