Architecture Differences

The two processors come from different AMD lineages. The EPYC 4124P is built on Zen 4 architecture (codenamed Raphael) using a 5 nm process at TSMC, while the Ryzen 5 7535U uses Zen 3+ (codenamed Rembrandt-R) on a 6 nm node. This generational gap explains much of the performance differential: the EPYC's newer architecture delivers higher instructions per clock, particularly evident in single-threaded scores.

Core configurations also differ substantially. The EPYC 4124P has 4 cores and 8 threads, while the Ryzen 5 7535U offers 6 cores and 12 threads. Despite having fewer cores, the EPYC wins multi-threaded benchmarks, which indicates the Zen 4 architecture's efficiency advantage over Zen 3+ outweighs the Ryzen's two extra physical cores. Cache hierarchies reinforce this: the EPYC provides 32 MB of shared L3 cache, double the Ryzen 5's 16 MB, and each EPYC core has 1 MB of L2 cache versus 512 KB per core on the Ryzen.

Clock speeds tell a similar story. The EPYC 4124P boosts to 5.10 GHz from a 3.80 GHz base, while the Ryzen 5 7535U boosts to 4.55 GHz from a 2.90 GHz base. The EPYC's higher boost clock, combined with its newer architecture, drives its 52.3% lead in Cinebench R23 single-core. The Ryzen 5's lower clocks are a concession to its 28-watt TDP, compared to the EPYC's 65-watt envelope.

Platform support diverges completely. The EPYC 4124P uses AMD Socket AM5 with PCIe Gen 5 (28 lanes), while the Ryzen 5 7535U uses Socket FP7 with PCIe Gen 4 (20 lanes). The EPYC also has a larger memory bandwidth rating at 83.2 GB/s versus 76.8 GB/s. Integrated graphics differ: the EPYC features Radeon Graphics, while the Ryzen 5 has Radeon 660M. Both support ECC memory, but the EPYC targets the Server/Workstation segment while the Ryzen 5 is designed for Mobile.

The manufacturing differences are stark. The EPYC 4124P packs 6,570 million transistors into a 71 mm² die, while the Ryzen 5 7535U uses a 208 mm² die with an unlisted transistor count. This density difference reflects the EPYC's newer process node and server-oriented design priorities.

Head-to-Head Benchmarks

The EPYC 4124P's biggest win comes in Cinebench R23 multi-core, where it scores 15264 against the Ryzen 5 7535U's 8591 — a 77.7% advantage. This is not a marginal victory; it is a complete rout in a workload that scales with cores and memory bandwidth. The EPYC also wins Cinebench R23 single-core by 52.3% (2154 vs 1414), proving its architectural superiority even when thread count is irrelevant.

PassMark results reinforce the EPYC's dominance in most areas. The EPYC leads in find prime numbers by 78% (89 vs 50), physics by 29.6% (1087 vs 839), and single-thread by 21.7% (3897 vs 3203). Extended instructions favor the EPYC by 14.1% (15049 vs 13187), as does random string sorting at 14.1% (24259 vs 21267). Even in multithread, where the Ryzen's 6-core advantage might help, the EPYC wins by 6.5% (18139 vs 17039). Data compression is close, with the EPYC ahead just 2.3% (204926 vs 200252), and Cinebench R15 multi-core shows a 15.6% EPYC lead (1538 vs 1330).

The Ryzen 5 7535U's wins are concentrated in math and encryption workloads. Its largest victory is in PassMark integer math, where it scores 62109 versus the EPYC's 52855 — a 14.9% lead. Floating-point math goes to the Ryzen by 7.2% (33971 vs 31518), and data encryption by 8.5% (12706 vs 11630). The Ryzen also edges out the EPYC in Cinebench R15 single-core by 4% (225 vs 216), a result that contrasts sharply with the newer Cinebench R23 single-core test where the EPYC wins by 52.3%.

These results paint a nuanced picture. The EPYC 4124P dominates rendering, compression, sorting, physics, and prime number calculations. The Ryzen 5 7535U excels at pure arithmetic operations and encryption, suggesting its Zen 3+ cores have strengths in specific instruction patterns despite overall lower performance.

The Verdict

The data is unambiguous for most workloads: the AMD EPYC 4124P is the faster processor. It wins 11 of 15 head-to-head benchmarks, including the most demanding multi-threaded tests. Its 77.7% lead in Cinebench R23 multi-core and 52.3% lead in single-core make it the clear choice for rendering, content creation, and any CPU-bound server task. The EPYC's 76th percentile ranking, matching the Ryzen's, is achieved with significantly higher benchmark scores in most categories.

The Ryzen 5 7535U is not without merit. Its 14.9% lead in integer math and 8.5% lead in encryption make it suitable for workloads dominated by those operations. The Ryzen's 28-watt TDP also indicates it can operate in thermally constrained environments where the 65-watt EPYC cannot. However, its lower single-thread scores (21.7% behind in PassMark) and dramatically lower multi-core scores limit its appeal for general-purpose computing.

For buyers choosing between these two, the decision hinges on workload and platform. The EPYC 4124P offers superior performance across almost all measurable categories, with the launch MSRP of $149. The Ryzen 5 7535U, with no listed launch MSRP, is a mobile part that trades performance for efficiency. The verdict is simple: if performance matters most, the EPYC 4124P wins. If low power consumption is critical and the workload is math-heavy, the Ryzen 5 7535U has specific advantages.
