Boost clocks reach 4.7 GHz on the Core Ultra 5 238V versus 5.1 GHz on the EPYC 4124P — a 8.2% clock advantage for the EPYC 4124P (base: 2.1 GHz vs 3.8 GHz). The Core Ultra 5 238V uses the Lunar Lake (2024) architecture (3 nm), while the EPYC 4124P uses Raphael (2023−2025) (5 nm). In PassMark, the Core Ultra 5 238V scores 18,219 against the EPYC 4124P's 18,139 — a 0.4% lead for the Core Ultra 5 238V. Cinebench R23 multi-core: 10,000 vs 10,500 (4.9% advantage for the EPYC 4124P). Geekbench 6 single-core — the metric most relevant to gaming — records 2,683 vs 1,962, a 31% lead for the Core Ultra 5 238V that directly translates to higher frame rates. Multi-core Geekbench: 10,130 vs 1,898 (136.9% advantage for the Core Ultra 5 238V). L3 cache: 8 MB (total) on the Core Ultra 5 238V vs 32 MB (total) on the EPYC 4124P.

The Core Ultra 5 238V uses the FCBGA2833 socket (PCIe 5.0), while the EPYC 4124P uses AM5 (PCIe 4.0) — making them incompatible on the same motherboard. Both support up to LPDDR5x-8533 memory speed. The EPYC 4124P supports up to 192 GB of RAM compared to 32 GB — 142.9% more capacity for professional workloads. Both feature 2-channel memory with ECC support. PCIe lanes: 8 (Core Ultra 5 238V) vs 28 (EPYC 4124P) — the EPYC 4124P offers 20 more lanes for additional GPUs or NVMe drives. Chipset compatibility: SoC (Core Ultra 5 238V) and B650,X670,X870 (EPYC 4124P).

Neither processor supports overclocking. Only the EPYC 4124P supports AVX-512 instructions — important for machine learning and scientific applications. Virtualization support: VT-x, VT-d (Core Ultra 5 238V) vs AMD-V, AMD-Vi (EPYC 4124P). Both include integrated graphics — Arc Graphics 130V (Core Ultra 5 238V) and Radeon Graphics (EPYC 4124P) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core Ultra 5 238V targets Productivity, EPYC 4124P targets Entry Server. Direct competitor: Core Ultra 5 238V rivals Ryzen 5 8640U; EPYC 4124P rivals Core i5-10500T.
