Xeon 6520P vs EPYC 75F3

The Xeon 6520P packs 24 cores / 48 threads, while the EPYC 75F3 offers 32 cores / 64 threads — the EPYC 75F3 has 8 more cores. Boost clocks reach 4 GHz on the Xeon 6520P versus 4 GHz on the EPYC 75F3 — identical boost frequencies (base: 2.4 GHz vs 2.95 GHz). The Xeon 6520P uses the Granite Rapids (2024−2025) architecture (Intel 3 nm), while the EPYC 75F3 uses Milan (2021−2023) (7 nm+). In PassMark, the Xeon 6520P scores 64,010 against the EPYC 75F3's 64,505 — a 0.8% lead for the EPYC 75F3. L3 cache: 144 MB (total) on the Xeon 6520P vs 256 MB (total) on the EPYC 75F3.

The Xeon 6520P uses the LGA4710 socket (PCIe 5.0), while the EPYC 75F3 uses SP3 (PCIe 4.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR5-6400 on the Xeon 6520P versus 3200 on the EPYC 75F3 — the EPYC 75F3 supports 199.4% faster memory, which can translate to measurable gains in memory-sensitive workloads. The EPYC 75F3 supports up to 4096 of RAM compared to 4 TB — 199.6% more capacity for professional workloads. Both feature 8-channel memory with ECC support. PCIe lanes: 88 (Xeon 6520P) vs 128 (EPYC 75F3) — the EPYC 75F3 offers 40 more lanes for additional GPUs or NVMe drives. Chipset compatibility: FCLGA4710 (Xeon 6520P) and SP3 (EPYC 75F3).

Neither processor supports overclocking. Only the Xeon 6520P supports AVX-512 instructions — important for machine learning and scientific applications. Both support VT-x, VT-d virtualization. Primary use case: Xeon 6520P targets Server. Direct competitor: Xeon 6520P rivals EPYC 9254; EPYC 75F3 rivals Xeon Platinum 8380.

The Xeon 6520P launched at $1295 MSRP, while the EPYC 75F3 debuted at $5383. At current prices ($1295 vs $2799), the Xeon 6520P is $1504 cheaper. In terms of value (PassMark points per dollar), the Xeon 6520P delivers 49.4 pts/$ vs 23.0 pts/$ for the EPYC 75F3 — making the Xeon 6520P the 72.8% better value option.
