The AMD EPYC 7551P processor is a member of AMD’s second-generation EPYC family, built on the Zen+ architecture. This powerful server processor aims to provide exceptional performance, scalability, and efficiency for demanding workloads in data centers, cloud computing, and enterprise environments.

Architecture and Features

The AMD EPYC 7551P processor features 32 cores (4 dies) with a base clock speed of 2.05 GHz and a boost clock speed of up to 3.0 GHz. Each core has a 16MB L3 cache, resulting in a total of 512MB of shared cache memory. The processor also boasts a 64-lane PCIe interface, supporting high-speed storage and I/O devices.

One of the notable features of the EPYC 7551P is its support for AMD’s Secure Encrypted Virtualization (SEV) technology, which enables secure virtualization by encrypting sensitive data in real-time. Additionally, the processor supports AMD’s Infinity Fabric interconnect, allowing for high-speed communication between cores and other system components.

Performance

The AMD EPYC 7551P processor demonstrates exceptional performance in various benchmarks, including CPU-bound workloads like Cinebench R20 and SPECrate2006. In these tests, it outperforms Intel’s competing Xeon SP processors, showcasing its ability to handle demanding tasks with ease.

In multi-threaded applications like Apache Cassandra and Memcached, the EPYC 7551P processor exhibits impressive scalability, leveraging its 32 cores and high clock speeds to deliver outstanding results.

Power Efficiency

The AMD EPYC 7551P processor is designed to provide exceptional power efficiency while maintaining high performance. Its thermal design power (TDP) of 180W allows for efficient cooling in data centers and server environments, reducing energy consumption and increasing overall system reliability.

Comparison with Competitors

When compared to Intel’s Xeon SP processors, the AMD EPYC 7551P offers competitive performance and pricing. In fact, the EPYC 7551P processor provides a higher core count and better scalability than its Xeon SP counterparts at similar price points.

For example, the EPYC 7551P processor with 32 cores costs around $3,700, while Intel’s Xeon Gold 6254 processor with 18 cores costs around $2,500. However, it’s essential to consider that the Xeon Gold 6254 processor has a higher single-threaded performance due to its higher clock speeds and lower IPC (instructions per cycle).

Conclusion

The AMD EPYC 7551P processor is an exceptional server processor designed for demanding workloads in data centers, cloud computing, and enterprise environments. Its 32 cores, high clock speeds, and advanced features like SEV and Infinity Fabric interconnect make it a compelling choice for organizations seeking scalable and secure solutions.

While its power efficiency may not be as impressive as some of its competitors, the EPYC 7551P processor offers exceptional performance and value in its price class. With its competitive pricing and robust feature set, it’s an attractive option for IT professionals and data center administrators looking to upgrade their infrastructure.
