AMD EPYC 7502P vs Intel Xeon Platinum 8280 Comparison

The AMD EPYC 7502P and Intel Xeon Platinum 8280 are both high-end server processors, yet the benchmark data reveals a strikingly consistent performance gap. Across every measured Cinebench workload, the AMD EPYC 7502P decisively outperforms the Intel Xeon Platinum 8280, with a uniform 22.7% lead in both single-core and multi-core tests. This consistency suggests a fundamental architectural advantage rather than a workload-specific quirk, warranting a closer look at what drives this result.

Where Each One Wins

The benchmark results are unambiguous: the AMD EPYC 7502P wins all six head-to-head tests, covering both multi-core and single-core performance across three generations of Cinebench (R15, R20, and R23). The Intel Xeon Platinum 8280 does not claim a single victory in any of these comparisons. This means the EPYC 7502P is the superior choice for rendering tasks, 3D modeling, and any workload that scales with CPU compute throughput.

However, the data does not show where the Xeon Platinum 8280 might excel. There are no benchmark entries for memory bandwidth, I/O throughput, or power efficiency in the fact pack. The Xeon's strengths, if any, would have to be inferred from its specifications, but the available performance metrics paint a one-sided picture. For users prioritizing raw compute in Cinebench-style workloads, the AMD part is the clear winner; the Intel part's use case is not supported by the provided benchmark data.

Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD EPYC 7502P is built on the Zen 2 architecture (codename Rome) using a 7 nm process from TSMC. It packs 32 cores and 64 threads, with a base clock of 2.50 GHz and a boost clock of 3.35 GHz. Its cache hierarchy is notable: 96 KB of L1 per core, 512 KB of L2 per core, and a massive 128 MB shared L3 cache. The chip is fabbed on a 74 mm² die with 3,800 million transistors, and it uses the AMD Socket SP3.

In contrast, the Intel Xeon Platinum 8280 uses the Cascade Lake architecture (codename Cascade Lake-SP) on Intel's older 14 nm process. It offers 28 cores and 56 threads, with a higher base clock of 2.70 GHz and a boost clock of 4.00 GHz. Its cache is smaller: 64 KB of L1 per core, 1 MB of L2 per core, and 38.5 MB of shared L3. The die size is not listed, but the transistor count is higher at 8,000 million, reflecting the less dense 14 nm process. It uses the Intel Socket 3647.

The process node advantage is stark: 7 nm versus 14 nm. This explains the EPYC's ability to fit more cores (32 vs. 28) while also offering a larger shared L3 cache (128 MB vs. 38.5 MB). The higher transistor count on the Intel part is likely due to the larger process geometry, not superior complexity. Both support DDR4 memory and ECC, but the EPYC 7502P features eight-channel memory with a bandwidth of 204.8 GB/s, while the Xeon's memory bus and bandwidth are not listed in the fact pack. The EPYC also supports PCIe Gen 4, while the Xeon's PCIe generation is unspecified.

Head-to-Head Benchmarks

The performance delta is identical across all six tests: 22.7% in favor of the AMD EPYC 7502P. This uniformity is remarkable and simplifies the analysis. In Cinebench R15 multi-core, the EPYC scores 4374 against the Xeon's 3564. In single-core, the EPYC scores 617 against 503. Moving to Cinebench R20, the EPYC leads with 18225 multi-core and 2572 single-core, versus the Xeon's 14854 and 2097, respectively. The pattern holds in Cinebench R23, where the EPYC achieves 43395 multi-core and 6126 single-core, while the Xeon manages 35367 and 4993.

The 22.7% lead in single-core is particularly telling. The Xeon has a higher boost clock (4.00 GHz vs. 3.35 GHz), yet it still loses by the same margin. This indicates that the Zen 2 architecture's instructions-per-clock (IPC) is substantially higher than Cascade Lake's, more than offsetting the clock speed deficit. The multi-core results are then amplified by the EPYC's additional 4 cores and 8 threads, but the fact that the percentage does not grow larger suggests the single-core IPC advantage is the dominant factor.

Looking at the nearest rivals for context, the EPYC 7502P's average benchmark score is 10512, placing it just 0.3% below the AMD EPYC 7D12 (10547) and 0.4% below the Intel Core i7-4790 (10556). It is 1.4% ahead of the Intel Xeon W-3175X (10369) and 1.6% ahead of the Intel Xeon Gold 6338N (10347). The Xeon Platinum 8280's average score is 10230, which is 0.6% below the Intel Xeon Gold 6312U (10291), 0.7% above the AMD EPYC 7F52 (10159), 0.9% below the Intel Xeon E3-1565L v5 (10320), and 1.1% below the Intel Xeon Gold 6338N (10347). Both processors sit at the 66th percentile among all CPUs, indicating they are in the same general performance tier, but the EPYC 7502P is consistently at the top of that tier.

The Verdict

The data is unequivocal. The AMD EPYC 7502P wins every benchmark in the comparison, with a commanding 22.7% lead in both single-core and multi-core workloads. For users running Cinebench or similar render workloads, the EPYC 7502P is the superior choice. Its 32 cores, larger 128 MB L3 cache, and 7 nm process deliver a decisive performance advantage over the Intel Xeon Platinum 8280's 28 cores and 38.5 MB L3 cache. The Xeon's higher boost clock does not compensate for the architectural efficiency of Zen 2.

The Intel Xeon Platinum 8280 is not without merit, but the provided data does not support a case for it in compute-heavy tasks. Its lower TDP of 205 W versus the EPYC's 180 W is notable, as is its higher transistor count, but these do not translate into benchmark wins. For a server/workstation CPU where raw rendering speed is paramount, the AMD EPYC 7502P is the clear pick. The Xeon Platinum 8280 might be considered in systems already invested in the Intel Socket 3647 platform, but based purely on the benchmark results, it trails the EPYC 7502P in every measurable way. The 66th percentile ranking for both chips places them in a similar tier, but the head-to-head data shows the EPYC 7502P is consistently at the upper bound of that tier.
