The Verdict

The benchmark data paints a clear picture for most workloads: the AMD EPYC 4565P is the stronger performer in the vast majority of measured tasks. It wins 16 of the 17 head-to-head benchmarks, including every Cinebench test, every Passmark throughput test except floating-point math, and all single-threaded checks. The average benchmark score for the AMD part is 95764, placing it in the 96th percentile of all CPUs, while the Intel Xeon w7-2575X averages 88172 and also sits in the 96th percentile. The AMD part sits within 0.2% of the AMD EPYC 9175F and 0.6% above the AMD EPYC 4564P in its nearest-rival grouping, so it is competitively placed among its own peers.

The Intel Xeon w7-2575X is the choice only when floating-point math throughput is the dominant concern, as it beats the AMD part by 11.3% in Passmark floating-point math. It also brings a wider memory bus and more PCIe lanes, which can matter for systems with heavy memory traffic or many expansion devices. The Intel part is unlocked, allowing overclocking, and it has a higher TDP of 250 watts versus 170 watts for the AMD chip.

For the majority of buyers, the AMD EPYC 4565P is the practical pick. It delivers a 22.9% lead across every Cinebench generation tested, a 42.8% lead in single-threaded Passmark, and a 21.9% lead in Passmark multithread. The data shows no scenario outside floating-point math where the Intel part wins. The Intel Xeon w7-2575X remains relevant for niche floating-point or high-memory-bandwidth deployments, but the AMD EPYC 4565P is the more broadly capable workstation processor.

Head-to-Head Benchmarks

The AMD EPYC 4565P dominates the Cinebench suite with a consistent 22.9% advantage across all six tests. In Cinebench R15 multicore, it scores 5484 versus 4463. In R15 single-core, it scores 774 versus 630. The R20 multicore result is 22850 against 18596, and the R20 single-core result is 3225 against 2625. In R23 multicore, the AMD part scores 54405 versus 44277, and in R23 single-core, it scores 7680 versus 6250. These results indicate a uniform architectural advantage in both lightly threaded and heavily threaded rendering workloads.

Passmark results reinforce the AMD lead in most categories. The largest single delta is in Passmark single-thread, where the AMD EPYC 4565P scores 4712 versus 3300, a 42.8% advantage. Passmark physics shows a 33.9% lead (2976 versus 2222), and Passmark find prime numbers shows a 34.9% lead (294 versus 218). Passmark data encryption is 22.8% higher on the AMD part (48268 versus 39295), and Passmark multithread is 21.9% higher (63474 versus 52091). Passmark integer math favors AMD by 14% (250683 versus 219924), and Passmark data compression favors AMD by 9% (860786 versus 789817). Passmark extended instructions is closer, at 3% (64345 versus 62498), and Passmark random string sorting is also close, at 4.3% (81318 versus 77986).

The Intel Xeon w7-2575X takes a single victory in Passmark floating-point math, scoring 171427 versus 152003 for the AMD EPYC 4565P, a margin of 11.3%. This is the only head-to-head benchmark where the Intel part leads, and it is a meaningful one for scientific or simulation workloads that rely heavily on floating-point throughput. Across all other recorded tests, the AMD processor holds the advantage, often by double-digit percentages.

Specification Differences

The core and thread counts differ significantly. The Intel Xeon w7-2575X has 22 cores and 44 threads, while the AMD EPYC 4565P has 16 cores and 32 threads. Clock speeds also differ: the AMD part has a base clock of 4.30 GHz and a boost clock of 5.70 GHz, while the Intel part has a base clock of 3.00 GHz and a boost clock of 4.80 GHz. The AMD processor runs at a 170 watt TDP, while the Intel processor is rated at 250 watts.

Memory configuration is another differentiator. The AMD EPYC 4565P uses a dual-channel DDR5 memory bus with 89.6 GB/s of bandwidth. The Intel Xeon w7-2575X uses a quad-channel DDR5 memory bus with 153.6 GB/s of bandwidth. Both support ECC memory. PCIe connectivity also differs: the AMD processor provides 24 PCIe Gen 5 lanes from the CPU, while the Intel processor provides 64 PCIe Gen 5 lanes from the CPU.

The AMD EPYC 4565P includes integrated Radeon Graphics, whereas the Intel Xeon w7-2575X has no integrated graphics. The AMD part is socketed for AMD Socket AM5, and the Intel part uses Intel Socket 4677. The AMD processor is not multiplier unlocked, while the Intel processor is multiplier unlocked, enabling overclocking. The AMD part has a part number of 100-000001559, and the Intel part has a part number of SRN4D. The AMD EPYC 4565P was released on 2025-05-12, and the Intel Xeon w7-2575X was released on 2024-08-23.

Architecture Differences

The AMD EPYC 4565P is built on the Zen 5 architecture, codenamed Grado, part of the EPYC 4005 series. It uses a 4 nm process from TSMC, with 16,630 million transistors and a die size of 2x 70.6 mm². The cache layout includes 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3 cache.

The Intel Xeon w7-2575X is based on the Sapphire Rapids codename, part of the Xeon W generation. It uses a 10 nm process from Intel. Its cache layout includes 80 KB of L1 per core, 2 MB of L2 per core, and 45 MB of L3 cache. No transistor count or die size figures are recorded for the Intel part.

The process node difference is stark: 4 nm for AMD versus 10 nm for Intel. This explains part of the clock speed and efficiency gap, as the AMD part achieves higher clocks at a lower 170 watt TDP. The AMD part also has more L3 cache (64 MB versus 45 MB) and a smaller L2 per core (1 MB versus 2 MB). The Intel part compensates with more cores and a wider memory bus, but the benchmark data shows that the AMD architecture wins the vast majority of measured workloads despite the core count disadvantage.

Where Each One Wins

The AMD EPYC 4565P is the clear winner in single-threaded and lightly threaded workloads. Its 42.8% lead in Passmark single-thread and 22.9% lead in every Cinebench single-core test make it the better choice for tasks that depend on per-core performance, such as legacy software, interactive workstation use, and lightly threaded compilation steps. It also wins heavily in integer math, encryption, compression, physics, and multithreaded throughput, making it the more versatile processor for general workstation and server duties.

The Intel Xeon w7-2575X wins in floating-point math by 11.3%, which makes it the preferred option for workloads that are heavily floating-point bound, such as certain scientific simulations, financial modeling, or engineering analysis. Beyond that, the Intel part offers a quad-channel memory bus with 153.6 GB/s of bandwidth, which is nearly double the AMD part's 89.6 GB/s, and 64 PCIe Gen 5 lanes versus 24, making it the better fit for systems with dense memory requirements or many high-speed expansion cards. The Intel part is also multiplier unlocked, which may appeal to users who plan to overclock, though the data does not include overclocked benchmark results.

For a balanced workstation processor, the AMD EPYC 4565P is the stronger option based on the recorded benchmarks. For a specialized floating-point or high I/O system, the Intel Xeon w7-2575X has clear advantages in memory bandwidth, PCIe capacity, and floating-point math.
