Where Each One Wins

The AMD Ryzen 3 3100U wins in the overall average benchmark score category, recording 6247 versus the EPYC 7401P's 5814. It also holds a higher percentile ranking at 62 versus 61. In terms of clock speeds, the Ryzen 3 3100U has a boost clock of 3.20 GHz compared to the EPYC 7401P's 3.00 GHz, giving it a single-thread clock advantage. The Ryzen 3 3100U also uses a newer process node at 12 nm versus the EPYC 7401P's 14 nm node, which contributes to its much lower thermal design power of 15 watts compared to 170 watts. The Ryzen 3 3100U includes integrated graphics with Radeon Vega 8, while the EPYC 7401P has no integrated graphics. For mobile or compact systems requiring integrated display output and minimal power draw, the Ryzen 3 3100U is the clear choice.

The AMD EPYC 7401P wins decisively in core and thread counts, offering 24 cores and 48 threads versus the Ryzen 3 3100U's 2 cores and 2 threads. This gives it a 12-fold advantage in core count and a 24-fold advantage in thread count. The EPYC 7401P also has a much larger L3 cache at 64 MB shared, compared to the Ryzen 3 3100U's 4 MB shared L3 cache. Its eight-channel memory bus and 170.6 GB/s memory bandwidth dwarf the Ryzen 3 3100U's dual-channel 38.4 GB/s configuration. The EPYC 7401P supports ECC memory, which the Ryzen 3 3100U does not, making it suitable for error-sensitive server workloads. The EPYC 7401P also features an unlocked multiplier, whereas the Ryzen 3 3100U's multiplier is locked. For server or workstation deployments requiring massive parallel throughput, extensive memory bandwidth, and ECC reliability, the EPYC 7401P is the appropriate selection.

Specification Differences

The two processors differ in nearly every core specification. The Ryzen 3 3100U has 2 cores and 2 threads, while the EPYC 7401P has 24 cores and 48 threads. Base clocks differ significantly: the Ryzen 3 3100U runs at 1.90 GHz base, while the EPYC 7401P runs at 2000.00 GHz base (the recorded value is likely a data entry artifact, but the number as recorded is 2000.00). Boost clocks are 3.20 GHz for the Ryzen 3 3100U and 3.00 GHz for the EPYC 7401P. Thermal design power is 15 watts for the Ryzen 3 3100U versus 170 watts for the EPYC 7401P.

The socket types are incompatible: the Ryzen 3 3100U uses AMD Socket FP5, while the EPYC 7401P uses AMD Socket SP3. The Ryzen 3 3100U targets the Mobile market segment, while the EPYC 7401P targets the Server/Workstation segment. The Ryzen 3 3100U has integrated Radeon Vega 8 graphics; the EPYC 7401P has no integrated graphics. The Ryzen 3 3100U's multiplier is locked, while the EPYC 7401P's multiplier is unlocked.

ECC memory is supported only on the EPYC 7401P. Part numbers also differ: YM3100C4T2OFG for the Ryzen 3 3100U and PS740PBEVHCAF for the EPYC 7401P. Release dates are recorded as 2026-05-31 for the Ryzen 3 3100U and 2017-06-28 for the EPYC 7401P.

Architecture Differences

The Ryzen 3 3100U is built on the Picasso codename, belonging to the Ryzen 3 generation with Zen+ (Picasso) architecture. The EPYC 7401P uses the Naples codename, belonging to the EPYC generation with Zen (Naples) architecture. Process nodes differ: the Ryzen 3 3100U is fabricated on a 12 nm node, while the EPYC 7401P uses a 14 nm node. Both are manufactured by GlobalFoundries. Transistor counts are close: 4,940 million for the Ryzen 3 3100U and 4,800 million for the EPYC 7401P. Die sizes are similar as well: 210 mm² for the Ryzen 3 3100U and 213 mm² for the EPYC 7401P.

Cache hierarchies share the same per-core L1 and L2 sizes: 96 KB L1 per core and 512 KB L2 per core for both. The L3 cache differs substantially: the Ryzen 3 3100U has 4 MB shared L3, while the EPYC 7401P has 64 MB shared L3, a 16-fold difference. Both support DDR4 memory and PCIe Gen 3. The Ryzen 3 3100U carries the Radeon Vega 8 integrated graphics, a feature absent from the EPYC 7401P. The architectural split reflects fundamentally different design goals: Zen+ on 12 nm for efficient mobile computing versus Zen on 14 nm for high-core-count server workloads.

The Verdict

The data presents a clear split. The AMD Ryzen 3 3100U should be chosen for mobile or compact deployments where low power consumption, integrated graphics, and a high average benchmark score relative to its class matter. Its 15-watt TDP, Radeon Vega 8 graphics, and 62nd percentile ranking make it suitable for lightweight portable systems. Its higher boost clock of 3.20 GHz and newer 12 nm process node give it an edge in single-thread responsiveness, while its average score of 6247 places it above the EPYC 7401P in overall benchmark performance.

The AMD EPYC 7401P should be chosen for server or workstation environments requiring massive parallelism, extensive memory bandwidth, and ECC reliability. Its 24 cores and 48 threads provide a 12-fold core advantage and 24-fold thread advantage over the Ryzen 3 3100U. The 64 MB L3 cache, eight-channel memory bus with 170.6 GB/s bandwidth, and ECC support make it appropriate for database, virtualization, and compute-heavy server tasks. Its unlocked multiplier allows tuning for specific workloads. Despite recording a lower average score of 5814 and a 61st percentile ranking, the EPYC 7401P's architectural strengths in core count and memory throughput are what matter for server-class workloads. The choice between the two is not about which is better overall, but which fits the target workload: the Ryzen 3 3100U for efficient client-side computing, and the EPYC 7401P for high-throughput server operations.
