AMD EPYC 7702P vs AMD Ryzen 5 3501U Comparison

Where Each One Wins

The AMD EPYC 7702P is a server-class processor built for massive parallel workloads. Its 64 cores and 128 threads dominate heavily threaded applications. In Cinebench R15 multicore, it scores 5272, and in R20 multicore it reaches 21969. The R23 multicore result of 52308 further cements its position. The Ryzen 5 3501U, with 4 cores and 4 threads, cannot compete in these arena. Its PassMark multithread score of 7071 is a fraction of the EPYC’s capability.

The Ryzen 5 3501U wins in single-threaded performance and power efficiency. Its boost clock of 3.70 GHz surpasses the EPYC’s 3.35 GHz. In PassMark single-thread tests, it scores 2136. The EPYC 7702P does not have a directly comparable PassMark single-thread score in the database, but its Cinebench R15 single-core score of 744 and R20 single-core of 3101 show a different optimization profile. The 3501U also excels in tasks like data compression, scoring 87380 in PassMark data compression, and integer math at 26321.

The EPYC 7702P is the clear winner for server virtualization, database processing, scientific computing, and any workload that scales across many cores. The Ryzen 5 3501U is designed for mobile devices, where its 15 W TDP and integrated Radeon Vega 8 graphics make it suitable for everyday productivity, light content creation, and power-sensitive applications. The data shows a complete split: the EPYC is for throughput, the Ryzen for responsiveness and portability.

Architecture Differences

The two processors come from different AMD generations and design philosophies. The EPYC 7702P is built on the Zen 2 architecture, codenamed Rome, and manufactured on a 7 nm process at TSMC. It uses 3,800 million transistors on a 74 mm² die. The Ryzen 5 3501U is based on the Zen+ architecture, codenamed Picasso, produced on a 12 nm process at GlobalFoundries. It packs 4,940 million transistors on a 210 mm² die, significantly larger due to the older process and integrated graphics.

Cache configurations diverge sharply. The EPYC 7702P has 96 KB of L1 per core, 512 KB of L2 per core, and a massive 256 MB of shared L3 cache. The Ryzen 5 3501U also has 96 KB L1 and 512 KB L2 per core, but only 4 MB of shared L3. This 64x difference in L3 capacity directly impacts how much data can be held on-chip for multi-threaded workloads.

Memory support differs in scale. The EPYC 7702P uses eight-channel DDR4 memory with a theoretical bandwidth of 204.8 GB/s and supports ECC memory. The Ryzen 5 3501U uses dual-channel DDR4 with 38.4 GB/s bandwidth and does not support ECC. PCIe generation also differs: the EPYC offers Gen 4, while the Ryzen uses Gen 3.

The EPYC 7702P has no integrated graphics, relying on discrete server GPUs or no display output. The Ryzen 5 3501U includes Radeon Vega 8 integrated graphics, making it a complete mobile solution. Sockets reflect their markets: the EPYC uses AMD Socket SP3 for servers, while the Ryzen uses Socket FP5 for laptops.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, so a direct test-by-test comparison is not possible. Instead, the available benchmark suites show where each processor excels.

The EPYC 7702P’s Cinebench results tell a clear story. In R15 multicore, it scores 5272, which is a massive result for a server chip. The R20 multicore score of 21969 and R23 multicore score of 52308 reinforce its multi-threaded dominance. Single-core scores are respectable but not exceptional: 744 in R15, 3101 in R20, and 7384 in R23.

The Ryzen 5 3501U’s PassMark results show a different profile. Its multithread score of 7071 is low compared to the EPYC’s Cinebench multicore values, but that is expected for a 4-core mobile chip. The Ryzen shines in specific tasks: data compression scores 87380, floating point math scores 12707, and integer math scores 26321. Its single-thread score of 2136 indicates strong per-core performance for a 15 W part.

In terms of average benchmark scores, the EPYC 7702P has an average of 15130 across its benchmarks, while the Ryzen 5 3501U averages 14320. Both processors sit at the 69th percentile of all CPUs in the database.

The Intel Core 5 211TE scores 15370, putting it 1.6% ahead of the EPYC.

The Ryzen 5 3501U’s nearest rivals are closer in score. The AMD Ryzen Embedded V2546 averages 14336, just 0.1% behind the Ryzen. The AMD Ryzen 3 7320C scores 14277, a 0.3% delta. Intel Core 7 160UL scores 14232, and Intel Core i5-10400F scores 14185, with deltas of 0.6% and 1.0% respectively.

The data indicates that the EPYC 7702P’s advantage is in raw multi-core throughput, while the Ryzen 5 3501U’s advantage is in per-watt performance and single-thread agility. The EPYC’s nearest rivals in the database are a mix of server and mobile chips, showing its average is competitive with a wide range of processors. The Ryzen’s rivals are mostly embedded and low-power parts, reflecting its mobile positioning. Neither processor has a clear win in the empty head-to-head table, but the benchmark suites show the EPYC 7702P as the undisputed king of heavily threaded work, while the Ryzen 5 3501U offers a balanced mobile experience with integrated graphics and a 15 W envelope.
