AMD EPYC 9454P vs Intel Xeon 6325P Comparison

The Verdict

The database comparison between the Intel Xeon 6325P and the AMD EPYC 9454P is not a contest of equals. The AMD EPYC 9454P wins all six recorded head-to-head benchmark comparisons, with a uniform performance advantage of 83.2% in every test. The data shows a processor designed for dense, high-throughput server workloads against a low-power entry point in Intel's Xeon lineup. The EPYC 9454P is the clear choice for any task where raw compute throughput, memory bandwidth, or PCIe expansion capacity is the primary requirement. The Intel Xeon 6325P, with its 4 cores and 8 threads, occupies a niche for workloads that are highly latency-sensitive or that require minimal power draw, but its benchmark results place it far behind the EPYC part in every measured category. For anyone building a server or workstation that needs to handle parallel processing, the AMD EPYC 9454P is the only rational selection from this pair. For a system where energy efficiency and a compact footprint outweigh core count, the Xeon 6325P offers a functional, if dramatically less powerful, alternative.

Architecture Differences

The two processors represent fundamentally different design philosophies. The Intel Xeon 6325P is built on Raptor Lake architecture, specifically the Raptor Lake-R refresh, and uses a 10 nm process node fabricated by Intel. It packs just 4 cores and 8 threads, with a base clock of 3.50 GHz and a boost clock of 5.20 GHz. The die size is 163 mm². Its cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and a shared 12 MB L3 cache. It supports both DDR4 and DDR5 memory over a dual-channel bus, and provides PCIe Gen 5 with 16 lanes from the CPU. Its thermal design power is 55 watts.

The AMD EPYC 9454P belongs to the EPYC 9004 series, codenamed Genoa, and uses the Zen 4 architecture. It is manufactured on a 5 nm process by TSMC, with 52,560 million transistors spread across 8 dies, each 72 mm². This processor offers 48 cores and 96 threads, running at a base clock of 2.75 GHz and a boost clock of 3.80 GHz. It has 64 KB of L1 per core, 1 MB of L2 per core, and a massive shared 256 MB L3 cache. Memory support is exclusively DDR5, accessed through a twelve-channel memory bus with a recorded bandwidth of 460.8 GB/s. It provides PCIe Gen 5 with 128 lanes from the CPU. The thermal design power is 290 watts.

The architectural gulf is vast: the Xeon uses a consumer-style small-core design with high clock speeds, while the EPYC uses a many-core, high-bandwidth design with lower clocks but far more parallelism. The EPYC's L3 cache is over 21 times larger, its memory channels are six times more numerous, and its PCIe lane count is eight times higher. The Xeon's advantage lies in clock speed, with a boost clock 1.40 GHz higher, and in a much lower thermal envelope. The EPYC's process node is a full generation ahead, which partially explains how it achieves higher throughput despite lower clocks.

Head-to-Head Benchmarks

The recorded head-to-head benchmark data is striking for its consistency. Across all six Cinebench tests, the AMD EPYC 9454P wins with a delta percentage of exactly -83.2% relative to the Intel Xeon 6325P. This uniform margin indicates that the EPYC's advantage scales linearly with the workload, regardless of whether the test is single-threaded or multi-threaded.

In Cinebench R15 multicore, the EPYC scores 8214 against the Xeon's 1382. This is a difference of 6832 points. In the single-core variant of R15, the EPYC scores 1159 against the Xeon's 195, a gap of 964 points. The single-core result is particularly notable because the Xeon has a significantly higher boost clock (5.20 GHz versus 3.80 GHz), yet it still loses by 83.2%. This suggests the EPYC's Zen 4 architecture delivers far more instructions per clock, or that the Xeon's high boost clock is not sustained in this workload.

Moving to Cinebench R20, the multicore test shows the EPYC at 34226 and the Xeon at 5761. The EPYC leads by 28465 points. The single-core R20 test shows the EPYC at 4831 and the Xeon at 813, a lead of 4018 points. In Cinebench R23, the multicore result is 81492 for the EPYC versus 13717 for the Xeon, a margin of 67775 points. The single-core R23 test shows 11504 for the EPYC against 1936 for the Xeon, a gap of 9568 points.

The data does not show a single benchmark where the Intel Xeon 6325P takes a win. The wins count is 0 for the Xeon and 6 for the EPYC. The consistent 83.2% delta across all tests, including single-core tests where clock speed should favor the Xeon, points to a fundamental architectural efficiency advantage for the EPYC's Zen 4 core design, combined with its much larger cache and more advanced process node. The EPYC's 5 nm process and 256 MB L3 cache likely allow it to maintain higher effective throughput per clock than the Xeon's 10 nm process and 12 MB cache.

For practical purposes, any workload that runs on this benchmark suite will see the EPYC 9454P complete the task in a fraction of the time required by the Xeon 6325P. The Xeon's only recorded advantages are its higher clock speeds, lower TDP, dual-channel memory flexibility, and a much lower launch MSRP of $281 versus $4598. But in terms of measured compute performance, the EPYC dominates every single recorded metric.
