AMD EPYC 7542 vs Intel Xeon Platinum 8280 Comparison

Head-to-Head Benchmarks

The recorded data shows a consistent victory for the AMD EPYC 7542 across every Cinebench workload in the database. In the multicore tests, the EPYC 7542 posts 3886 points in Cinebench R15 versus 3564 for the Intel Xeon Platinum 8280, a margin of 8.3%. The R20 multicore results repeat the pattern: 16193 points for AMD against 14854 for Intel, again an 8.3% difference. The R23 multicore run shows 38555 for the EPYC 7542 and 35367 for the Xeon Platinum 8280, holding the same 8.3% gap.

Single-threaded performance tells the same story. The EPYC 7542 scores 548 in R15 single-core, while the Xeon Platinum 8280 manages 503, an 8.2% advantage. In R20 single-core, the gap is 8.3% with 2286 versus 2097. The R23 single-core test shows 5443 for the AMD part and 4993 for the Intel part, again 8.3%. No benchmark in the head-to-head set favors the Intel Xeon Platinum 8280; the EPYC 7542 wins all six recorded comparisons.

Looking at the average benchmark score across the full database, the EPYC 7542 reaches 11152, while the Xeon Platinum 8280 sits at 10230. That is a meaningful separation in the aggregate data, even if the individual Cinebench deltas cluster tightly around 8.3%. The nearest rival fields place the Intel part near the AMD EPYC 7F52 (10159, a 0.7% difference) and the Intel Xeon Gold 6338N (10347, a 1.1% difference). The AMD part, by contrast, sits close to the AMD EPYC 9224 (11118, a 0.3% difference) and the Intel Xeon Gold 6336Y (11191, a 0.3% difference). Both processors land at the 66th percentile of all CPUs in the database, so the overall rank does not differentiate them; the separation appears only in the direct comparison.

Q: Does the EPYC 7542 support PCIe Gen 4?

A: Yes. The database lists PCIe Gen 4 support for the AMD EPYC 7542. The Intel Xeon Platinum 8280 has no PCIe field recorded in the database.

Architecture Differences

The two processors come from different design schools. The Intel Xeon Platinum 8280 uses the Cascade Lake architecture, specifically Cascade Lake-SP, built on Intel's 14 nm process at Intel's own foundry. It integrates 8,000 million transistors. The AMD EPYC 7542 uses the Zen 2 architecture, codename Rome, fabricated on TSMC's 7 nm process, with 3,800 million transistors and a die size of 74 mm².

Core counts differ. The Xeon Platinum 8280 provides 28 cores and 56 threads, while the EPYC 7542 provides 32 cores and 64 threads. That gives the AMD part a 4-core and 8-thread advantage, which aligns with its multicore benchmark lead.

Cache layouts are quite different. The Intel part has 64 KB of L1 per core, 1 MB of L2 per core, and 38.5 MB of shared L3. The AMD part has 96 KB of L1 per core, 512 KB of L2 per core, and 128 MB of shared L3. The EPYC 7542's L3 cache is more than three times larger, which can help with data-heavy workloads that fit within the shared cache.

Clock behavior differs as well. The Xeon Platinum 8280 has a base clock of 2.70 GHz and a boost clock of 4.00 GHz. The EPYC 7542 has a base clock of 2.90 GHz and a boost clock of 3.40 GHz. The Intel part boosts higher, but the AMD part starts from a higher base. Neither processor has an unlocked multiplier, so overclocking is not a distinguishing factor.

Memory support is listed as DDR4 for both, and both support ECC memory. The AMD part has an eight-channel memory bus and a recorded memory bandwidth of 204.8 GB/s. The Intel part has no memory bus or bandwidth figure in the database. The EPYC 7542 uses the AMD Socket SP3, while the Xeon Platinum 8280 uses Intel Socket 3647. The EPYC 7542 is listed as active in production status, while the Xeon Platinum 8280 has no production status recorded.

Release timing differs by roughly eight months. The Xeon Platinum 8280 was released on 2018-12-10, and the EPYC 7542 on 2019-08-06. Both target the server/workstation market segment.

The Verdict

The benchmark data points to a single conclusion: the AMD EPYC 7542 outperforms the Intel Xeon Platinum 8280 in every recorded Cinebench workload. The multicore lead of 8.3% is consistent across R15, R20, and R23, and the single-core lead of roughly 8.2% to 8.3% is nearly as uniform. This is not a case of one chip winning heavily in one test and losing in another; the AMD part is faster across the board.

The Intel Xeon Platinum 8280 does have a higher boost clock (4.00 GHz versus 3.40 GHz) and a smaller process node disadvantage (14 nm versus 7 nm), but those factors do not translate into a benchmark victory in the recorded data. The EPYC 7542's higher base clock (2.90 GHz versus 2.70 GHz), larger core count (32 versus 28), and much larger L3 cache (128 MB versus 38.5 MB) appear to carry the day.

For workloads that rely on multi-threaded throughput, the EPYC 7542 is the clear pick based on the data. For single-threaded responsiveness, the EPYC 7542 also holds the edge in every recorded test, even though the Intel part has the higher boost clock. The aggregate benchmark score reinforces this: 11152 versus 10230 favors AMD.

The absence of any recorded Intel win in the head-to-head set makes the verdict straightforward. A system builder choosing between these two specific processors, based solely on the database measurements, should select the AMD EPYC 7542. The Intel Xeon Platinum 8280 remains a capable server processor, as its 66th percentile rank and its proximity to the Intel Xeon Gold 6312U show, but it does not match the EPYC 7542 in the Cinebench workloads recorded here.

The two parts share DDR4 memory support, ECC memory support, a server/workstation market segment, a locked multiplier, and the absence of integrated graphics in the database.

Where Each One Wins

The AMD EPYC 7542 wins in every recorded benchmark category. In multicore workloads, the 8.3% advantage holds across all three Cinebench versions, which suggests a consistent throughput edge for heavily threaded rendering or simulation tasks. The larger core count and the larger L3 cache likely contribute to this result. The EPYC 7542 also wins in single-core tests by a similar margin, so even lightly threaded applications see a benefit in the recorded data.

The Intel Xeon Platinum 8280 does not win any recorded benchmark, but it has attributes that may matter outside the Cinebench results. Its higher boost clock of 4.00 GHz could favor bursty workloads that depend on peak clock speed, even though the recorded single-core tests do not reflect such an advantage. Its lower TDP of 205 watts, compared to 225 watts for the AMD part, suggests a lower thermal envelope in deployment, though the database does not include power or cooling measurements. The Intel part also uses the Intel Socket 3647 platform, which may be relevant for existing server infrastructure.

The EPYC 7542's support for PCIe Gen 4 and its eight-channel memory bus with 204.8 GB/s of bandwidth make it the stronger choice for memory-bandwidth-sensitive and I/O-heavy workloads, according to the recorded specifications. The Intel part lacks recorded PCIe and memory bandwidth figures, so those areas cannot be compared directly.

For a new deployment where raw Cinebench performance is the priority, the EPYC 7542 is the pick. For an environment that relies on the Intel Socket 3647 ecosystem or needs the lower 205-watt TDP, the Xeon Platinum 8280 remains a defensible option, even though the benchmark data does not show it winning any of the six head-to-head tests.
