CPU Comparison

The AMD EPYC 7J13 and Intel Xeon 6325P present one of the most lopsided matchups in the database, yet their average benchmark scores are nearly identical. The EPYC 7J13 averages 20,845 points, while the Xeon 6325P averages 20,821 points, a difference of only 0.1%. This apparent paradox stems from the fact that the averages are calculated from entirely different benchmark suites. The EPYC 7J13’s data comes exclusively from Cinebench tests, while the Xeon 6325P’s average includes a broader set of PassMark workloads. The head-to-head data, however, is unambiguous: across six Cinebench comparisons, the EPYC 7J13 wins every single one, with deltas ranging from 425.4% to 425.6%. The Xeon 6325P does not secure a single victory in these direct comparisons.

Where Each One Wins

The AMD EPYC 7J13 is the clear winner in every head-to-head benchmark recorded. Its dominance is absolute in Cinebench R15, R20, and R23, covering both single-core and multi-core tests. In multi-core R23, the EPYC scores 72,068 versus the Xeon’s 13,717, a 425.4% advantage. This makes the EPYC the obvious choice for any workload that scales with thread count, such as rendering, scientific computing, or database processing. The 64-core, 128-thread configuration provides a massive parallel throughput advantage that the 4-core, 8-thread Xeon cannot approach. Even in single-core tests, where the Xeon’s 5.20 GHz boost clock might be expected to help, the EPYC still wins decisively, scoring 10,174 in R23 single-core versus 1,936 for the Xeon, a 425.5% lead.

The Intel Xeon 6325P does not win any of the six head-to-head benchmarks. However, its PassMark results, which are not compared directly, show strengths in specific integer and floating-point operations. The Xeon scores 49,151 in integer math and 37,265 in floating-point math, alongside 178,020 in data compression. These figures suggest that in workloads not covered by the Cinebench suite, the Xeon might perform admirably for its size. The Xeon also has a much lower TDP of 55 watts versus 280 watts for the EPYC, implying that in power-constrained environments, it could be the more practical option, even if its raw performance is lower. The data shows that the Xeon’s wins are not in raw speed but in efficiency and specific instruction-level tasks.

A: Yes, both the AMD EPYC 7J13 and the Intel Xeon 6325P have an "Active" production status in the data.

Head-to-Head Benchmarks

The most striking result is the consistency of the EPYC’s victory margin. In Cinebench R15 multi-core, the EPYC scores 7,264 against the Xeon’s 1,382, a 425.6% lead. The single-core R15 test tells the same story: 1,025 versus 195, again 425.6%. Moving to R20, the multi-core score is 30,268 for the EPYC and 5,761 for the Xeon, a 425.4% delta. The single-core R20 result is 4,273 versus 813, a 425.6% gap. In R23, the multi-core scores are 72,068 and 13,717, a 425.4% difference, and the single-core scores are 10,174 and 1,936, a 425.5% difference.

These deltas are remarkably uniform, hovering around 425.5% across all tests. This suggests that the performance ratio is driven by a fundamental architectural scaling factor rather than test-specific optimizations. The EPYC’s 64 cores versus the Xeon’s 4 cores explain the multi-core gaps, but the single-core results are more surprising. The Xeon’s base clock of 3.50 GHz and boost clock of 5.20 GHz are both higher than the EPYC’s 2.55 GHz and 3.50 GHz, yet the EPYC still wins by the same margin. The data implies that the EPYC’s Zen 3 architecture is significantly more efficient per clock, or that the Xeon’s Raptor Lake cores are heavily constrained in this benchmark environment. The uniformity of the 425% delta across all six tests is a strong indicator of a consistent architectural advantage.

Specification Differences

The core and thread counts are the most obvious differences, with the EPYC offering 64 cores and 128 threads versus the Xeon’s 4 cores and 8 threads. The base clocks differ: the EPYC runs at 2.55 GHz, while the Xeon runs at 3.50 GHz. Boost clocks also differ, with the EPYC at 3.50 GHz and the Xeon at 5.20 GHz. The TDP is dramatically different, as the EPYC draws 280 watts while the Xeon only draws 55 watts. The sockets are incompatible: the EPYC uses AMD Socket SP3, while the Xeon uses Intel Socket 1700. The process nodes differ as well, with the EPYC on 7 nm from TSMC and the Xeon on 10 nm from Intel. The EPYC has a die size of 8x 81 mm², while the Xeon has a single 163 mm² die. The EPYC’s transistor count is 33,200 million, while the Xeon’s is not listed.

Memory support diverges significantly: the EPYC supports only DDR4 with an eight-channel bus and a bandwidth of 204.8 GB/s, while the Xeon supports both DDR4 and DDR5 with a dual-channel bus and no listed bandwidth. PCIe lanes also differ: the EPYC offers Gen 4 with 128 lanes, while the Xeon offers Gen 5 with 16 lanes. The Xeon has no integrated graphics listed, and the EPYC also has no integrated graphics. The Xeon has a release date of February 23, 2025, while the EPYC’s release date is not provided. The Xeon has a launch MSRP of $281, while the EPYC has no launch MSRP listed. Both have locked multipliers.

Architecture Differences

The AMD EPYC 7J13 is built on Zen 3 architecture with the codename Milan, representing the EPYC generation of the Zen 3 family. It uses an 8-chiplet design, with each die measuring 81 mm² on a 7 nm process at TSMC. The cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The Intel Xeon 6325P is based on Raptor Lake architecture, with the codename Raptor Lake-R, and belongs to the Xeon 6 generation (Raptor Lake Refresh). It uses a monolithic 163 mm² die on a 10 nm Intel process. Its cache is smaller per core in L1 at 80 KB, but larger in L2 at 1.25 MB per core, with a total of 12 MB of shared L3.

The EPYC’s 256 MB L3 cache is a defining feature, providing 21x more shared cache than the Xeon’s 12 MB. This explains its strong performance in multi-threaded workloads where data sharing is critical. The Xeon’s higher per-core L2 cache (1.25 MB versus 512 KB) suggests a focus on single-thread efficiency, but the benchmark data does not support this, as the EPYC wins single-core tests by the same margin. The memory controller differences are also architectural: the EPYC’s eight-channel DDR4 support with 204.8 GB/s bandwidth is far superior to the Xeon’s dual-channel design. The PCIe implementation differs, with the EPYC providing 128 Gen 4 lanes versus the Xeon’s 16 Gen 5 lanes. The EPYC’s transistor count of 33,200 million indicates a much larger overall design, despite the smaller individual chiplets.

The Verdict

The data is unequivocal for raw performance: the AMD EPYC 7J13 wins every head-to-head benchmark by a margin of approximately 425%. Any user prioritizing Cinebench scores, which are representative of rendering and compute-heavy tasks, should choose the EPYC without hesitation. Its 64 cores and 128 threads, combined with 256 MB of L3 cache and 204.8 GB/s of memory bandwidth, make it a server-class processor designed for maximum throughput. The benchmark results show that even in single-core tests, the EPYC’s architecture overcomes the Xeon’s higher clock speeds, suggesting that the Zen 3 core design is more efficient per clock cycle.

The Intel Xeon 6325P, while losing all direct comparisons, offers a different profile. Its 55-watt TDP is 80% lower than the EPYC’s 280 watts, which could be decisive in dense server environments or edge deployments where power and cooling are limited. Its PassMark results, while not directly compared, show strong scores in integer math (49,151), floating-point math (37,265), and data compression (178,020). These are not part of the head-to-head suite, so they do not affect the win count, but they indicate that the Xeon has capabilities in specific workload types. The Xeon also supports both DDR4 and DDR5 memory and has a launch MSRP of $281, which is a concrete data point for cost-sensitive procurement. For users who need a low-power, small-footprint server CPU with modern features like PCIe Gen 5, the Xeon is the logical pick. For anyone who needs maximum compute performance, the EPYC 7J13 is the only choice based on the data.
