The AMD EPYC 7551P is a high-performance server processor designed for datacenter and cloud computing applications. As the second-generation EPYC processor, it brings significant improvements in terms of performance, power efficiency, and features, making it an attractive option for businesses and organizations that require high-performance computing.

Architecture and Features

The AMD EPYC 7551P is built on the Zen+ microarchitecture, which provides improved instructions per clock (IPC) and reduced latency compared to its predecessor. The processor features a total of 32 cores and 64 threads, making it an ideal choice for applications that require high parallelism.

One of the standout features of the EPYC 7551P is its high memory bandwidth, thanks to its quad-channel DDR4 memory support and a maximum capacity of up to 2TB. This allows for seamless data transfer between cores and reduces latency in memory-intensive workloads.

Performance

In terms of performance, the AMD EPYC 7551P delivers impressive results across various benchmarking tools. In single-threaded workloads such as Cinebench R20, it achieves a score of up to 530 points, outperforming Intel’s Xeon Platinum 8180M processor in some tests.

In multi-threaded workloads like SPECrate2006 and SPECint_rate2006, the EPYC 7551P demonstrates its true capabilities, achieving scores of up to 14,500 and 13,400 respectively. These results are significantly higher than those achieved by competing processors from Intel and AMD’s own Ryzen Threadripper series.

Power Efficiency

The AMD EPYC 7551P is designed with power efficiency in mind, featuring a TDP (thermal design power) of up to 180W. However, thanks to its advanced cooling system and optimized architecture, it can operate at a lower power consumption than many competing processors, making it an attractive option for datacenters and cloud computing environments.

PCIe Lanes and Storage

The EPYC 7551P supports up to 128 PCIe lanes, allowing for the connection of multiple high-speed storage devices, network cards, and other peripherals. Additionally, it features 16 x UMI (Unified Memory Interface) channels, enabling seamless communication between cores and memory.

Comparison with Competitors

When compared to Intel’s Xeon Platinum 8180M processor, the AMD EPYC 7551P offers several advantages, including higher core counts, improved IPC, and reduced latency. However, Intel’s processor still outperforms the EPYC in certain workloads, such as single-threaded applications.

In comparison with AMD’s own Ryzen Threadripper series, the EPYC 7551P offers significantly better performance in multi-threaded workloads, thanks to its higher core counts and optimized architecture.

Conclusion

The AMD EPYC 7551P is a high-performance server processor that delivers impressive results across various benchmarking tools. Its advanced architecture, high memory bandwidth, and improved power efficiency make it an attractive option for businesses and organizations that require high-performance computing.

While it may not outperform Intel’s Xeon Platinum 8180M in every workload, the EPYC 7551P offers several advantages, including higher core counts, improved IPC, and reduced latency. As a result, it is an excellent choice for applications that require high parallelism and seamless data transfer between cores.
