AMD EPYC 7543P vs AMD EPYC 75F3 Comparison

The AMD EPYC 7543P and the AMD EPYC 75F3 are both 32-core, 64-thread server processors built on the same Zen 3 architecture, codenamed Milan. They share the same socket, memory support, and PCIe capabilities, but the benchmark data reveals a consistent performance gap between them. The recorded measurements show a clear pattern: the 7543P holds a small but uniform lead across every single-core and multi-core test in the database. This analysis walks through those results, what they mean for different workloads, and the architectural details that explain the differences.

Head-to-Head Benchmarks

The head-to-head data is remarkably consistent. Across all six Cinebench tests, the AMD EPYC 7543P wins every single matchup, with deltas of 3.3% or 3.4% in every case. There is no test where the EPYC 75F3 comes out ahead.

Starting with multi-core performance, the 7543P scores 5713 in Cinebench R15 multi-core, while the 75F3 scores 5526. That is a 3.4% lead. In Cinebench R20 multi-core, the gap remains the same: 23806 versus 23028, again 3.4%. The Cinebench R23 multi-core test shows the same story, with the 7543P at 56683 and the 75F3 at 54829, a 3.4% difference. These are not large margins, but they are perfectly consistent across all three generations of the Cinebench renderer.

The single-core results follow the exact same pattern. In Cinebench R15 single-core, the 7543P scores 806 versus 780 for the 75F3, a 3.3% lead. In Cinebench R20 single-core, the scores are 3360 and 3250, a 3.4% gap. Cinebench R23 single-core shows 8002 for the 7543P and 7740 for the 75F3, again 3.4%. The consistency is notable: whether the workload is single-threaded or fully parallel, the 7543P delivers roughly the same relative advantage.

The average benchmark score in the database confirms this overall picture. The 7543P has an average benchmark score of 16395, while the 75F3 sits at 15859. That difference is about 3.4%, matching the head-to-head deltas almost exactly. The percentile ranking versus all CPUs is identical for both processors at 70, meaning they land in the same overall tier relative to the broader CPU landscape.

Looking at the nearest rivals in the database provides additional context. The 7543P sits very close to the AMD Ryzen 5 4600H, which has an average score of 16341, a delta of 0.3%. The Intel Core i7-1260U is also nearby at 16320, a 0.5% delta, and the Intel Core i5-10600KF trails at 16228, a 1% delta. The 75F3 by comparison is positioned near the AMD Ryzen 5 40 at 15882, a negative 0.1% delta, the AMD EPYC 9354P at 15826, a 0.2% delta, the Intel Core Ultra 5 134U at 15910, a negative 0.3% delta, and the AMD EPYC 9334 at 15940, a negative 0.5% delta. Neither processor is dramatically far from its nearest neighbors, but the 7543P consistently sits in a slightly higher performance bracket.

Where Each One Wins

The win count in the head-to-head data is 6 for the 7543P and 0 for the 75F3. This means the 7543P is the better choice for every workload category represented by these benchmarks.

For multi-threaded rendering workloads, such as those modeled by Cinebench R15, R20, and R23 multi-core tests, the 7543P is the stronger performer. The advantage is around 3.4% in each case, which means tasks that scale across all 32 cores, like 3D rendering, video encoding, or scientific simulation, will complete slightly faster on the 7543P. The 75F3, despite its higher boost clock, cannot overcome the 7543P's measured multi-core advantage.

For single-threaded workloads, the 7543P also wins, with a 3.3% lead in Cinebench R15 single-core and 3.4% in both R20 and R23 single-core. This is somewhat counterintuitive given the 75F3's higher boost clock, but the recorded data is unambiguous. Tasks that rely on a single core, such as certain database queries, legacy software, or lightly threaded applications, will see a small but consistent benefit from the 7543P.

There are no benchmark categories where the 75F3 takes the lead. The data shows no wins for that processor in any of the six tests. Users considering the 75F3 for its higher clock speeds would not find support for that choice in the Cinebench results; the 7543P wins every measured scenario.

Architecture Differences

Both processors are built on the same Zen 3 architecture, codenamed Milan, and both use TSMC's 7 nm process node. The transistor count is identical at 33,200 million, and the die size is the same at 8x 81 mm². The cache hierarchy is also identical: 64 KB of L1 per core, 512 KB of L2 per core, and 256 MB of shared L3 cache. There is no difference in cache capacity between the two.

The key architectural differences lie in clock speeds and power. The 7543P has a base clock of 2.80 GHz and a boost clock of 3.70 GHz, with a TDP of 225 watts. The 75F3 has a base clock of 2.95 GHz and a boost clock of 4.00 GHz, with a TDP of 280 watts. So the 75F3 is clocked higher, both at base and boost, and draws 55 watts more power at its rated TDP.

Despite the 75F3's higher clocks, the benchmark results favor the 7543P. This suggests that the 7543P is able to sustain its performance more effectively in the measured workloads, or that the higher power draw of the 75F3 does not translate into better sustained performance in these particular tests. The database does not include power measurements or thermal data, so the exact reason cannot be confirmed from the recorded information alone.

Both processors share the same memory architecture as well. Memory support is DDR4 with an eight-channel memory bus and 204.8 GB/s of memory bandwidth. ECC memory is supported on both. PCIe connectivity is also identical: Gen 4 with 128 lanes (CPU only). The socket is AMD Socket SP3 for both parts. Neither processor has integrated graphics, and both are unlocked for multiplier adjustment, though this is less relevant for server platforms.

The release date is the same for both: 2021-03-14. Both are classified as server/workstation parts and both are listed as Active in production status. The part numbers differ, as do the launch MSRPs, with the 7543P at $2730 and the 75F3 at $4860.

All other specifications are identical: 32 cores, 64 threads, Zen 3 architecture, Milan codename, 7 nm process node from TSMC, 33,200 million transistors, 8x 81 mm² die size, 64 KB L1 per core, 512 KB L2 per core, 256 MB shared L3, DDR4 memory support, eight-channel memory bus, 204.8 GB/s memory bandwidth, ECC memory support, PCIe Gen 4 with 128 lanes (CPU only), AMD Socket SP3, no integrated graphics, server/workstation market segment, Active production status, same release date of 2021-03-14, and both are multiplier unlocked.

The Verdict

The data supports a clear conclusion. The AMD EPYC 7543P outperforms the AMD EPYC 75F3 in every measured benchmark. The 7543P leads by 3.3% to 3.4% across all six Cinebench tests, both single-core and multi-core. Its average benchmark score of 16395 is higher than the 75F3's 15859, and it holds a 6 to 0 win record in the head-to-head results.

The 75F3 offers higher clock speeds, with a base clock of 2.95 GHz and a boost clock of 4.00 GHz, compared to the 7543P's 2.80 GHz and 3.70 GHz. It also has a higher TDP at 280 watts versus 225 watts. However, these higher clocks do not produce higher benchmark scores in the recorded data. The 7543P consistently delivers better performance while drawing less power at its rated TDP.

For users choosing between these two processors based on the database measurements, the 7543P is the stronger option across the board. It wins every tested workload category, offers the same core count, cache, memory support, and PCIe capabilities, and does so with a lower TDP. The 75F3's higher clock speeds and higher launch MSRP do not translate into a performance advantage in any of the six Cinebench tests. The 7543P is the recommended pick for both multi-threaded and single-threaded workloads based on the recorded benchmark results.
