AMD EPYC 7551P

The AMD EPYC 7551P is a 32-core, 64-thread processor in the EPYC 7001 series, using AMD’s Zen architecture under the codename Naples. Released on 2017-06-28 and still in active production, it is built on a 14 nm process at GlobalFoundries and targets the server/workstation segment through AMD Socket SP3. Its aggregate benchmark score is 7952, placing it in the 68th percentile of all CPUs in the database, while its Cinebench and Geekbench scores reveal a wide gap between multi-core and single-core performance.

Benchmark Performance

Benchmark results show a processor designed around core count. In Cinebench R15, the EPYC 7551P scores 3276 multi-core and 462 single-core. In R20, it scores 13650 multi-core and 1926 single-core. In R23, it scores 32500 multi-core and 4588 single-core. Geekbench reports 6296 multi-core and 919 single-core. The average benchmark score of 7952 places it at the 68th percentile. That aggregate number is heavily influenced by the lower single-core results, even though the multi-core results are much larger.

Looking at the nearest rivals, the EPYC 7551P holds a narrow position below each one. The Intel Core i5-4570 has an average score of 8050, which is 1.2% higher than the EPYC’s 7952. The Intel Core i5-7400 is 2.1% higher with an average score of 8125. The AMD EPYC 7302 is 2.3% higher with an average score of 8139. The Intel Xeon Gold 5318Y is 2.4% higher with an average score of 8147. All four rivals sit within a 1.2-point percentage band above the EPYC 7551P, so the aggregate differences are small. Yet the multi-core Cinebench scores tell a different story from the aggregate ranking: the R23 multi-core figure of 32500 reflects a 64-thread part, while the aggregate average places it near parts with far fewer threads.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance is severe. Geekbench scores are 919 single-core and 6296 multi-core. Cinebench R23 scores are 4588 single-core and 32500 multi-core. This processor has a base clock of 2000.00 MHz and a boost clock of 3.00 GHz, meaning a single thread is capped by a modest 3.00 GHz ceiling. Multi-threaded scaling is the reason this CPU exists. The 32 cores and 64 threads, supported by 96 KB L1 cache per core, 512 KB L2 per core, and a 64 MB shared L3 cache, provide a large execution surface for threaded workloads.

The eight-channel DDR4 memory bus, rated at 170.6 GB/s, is another clue. Feeding 32 cores requires significant memory bandwidth, and the data shows that bandwidth is available. For workloads such as 3D rendering or parallel computation, the R23 multi-core score of 32500 is a strong signal. For lightly threaded tasks, the Geekbench single-core score of 919 is a more relevant number, and it indicates a much weaker result. The architecture is not balanced for single-thread responsiveness; it is balanced for scale-out parallel work.

Power and Thermals

The EPYC 7551P is rated at a 180 W TDP. That is a high thermal envelope for a 213 mm² die containing 4,800 million transistors on a 14 nm process. The 180 W TDP implies a cooling solution designed for high-power server or workstation sockets rather than a compact desktop system. The boost clock of 3.00 GHz is modest, which may help keep thermals manageable under sustained all-core loads. With no integrated graphics, the thermal burden comes almost entirely from the 32 cores and 64 threads. The base clock of 2000.00 MHz also suggests that heavy sustained workloads rely on the core count instead of high clock rates. The data does not include measured load temperatures, but the TDP class points to robust active cooling as the appropriate tier.

Who Should Consider It

Workloads with high thread parallelism are the clearest fit for the EPYC 7551P. The Cinebench R20 multi-core score of 13650 and R23 multi-core score of 32500 indicate strong scaling for multi-threaded rendering, simulation, and other compute-heavy tasks. The 170.6 GB/s of memory bandwidth and ECC support strengthen its case for memory-sensitive server work. Its market segment is explicitly server/workstation, so that is the intended environment.

For gaming, the single-core scores are the limiting factor. A Geekbench single-core score of 919 and a Cinebench R15 single-core score of 462 mean the processor will not excel in workloads that depend on one or two threads. The 32 cores do not help when a workload is bound to a single thread. Office productivity that is mostly single-threaded would also see little benefit from this architecture. By contrast, organizations running heavily threaded batch jobs are the audience this CPU is built for. The production status is active, so it remains an option for current systems in that role.
