AMD EPYC 7543P Server Processor – 32 Cores, 2.8 GHz, 256 MB L3, Socket SP3 (100-000000341)

The AMD EPYC 7543P 2.8 GHz processor is a server-grade CPU designed for data center and high-performance computing environments. Featuring 32 physical cores and a large 256 MB L3 cache, this Socket SP3 processor supports octa-channel DDR4 memory at up to 3200 MHz and offers a base frequency of 2.8 GHz with boost capability to 3.7 GHz. The design emphasizes throughput, multi-threaded performance and memory bandwidth to handle virtualization, database and compute-intensive workloads.

Advantages

The combination of 32 cores and an extensive 256 MB L3 cache provides sustained performance for parallel tasks and reduces latency for large working sets. Octa-channel DDR4 support increases memory bandwidth for data‑heavy applications, and compatibility with Socket SP3 motherboards ensures deployment flexibility in server racks. The processor’s boost frequency up to 3.7 GHz allows higher single‑thread performance when required, while the architecture is optimized for efficient multi-core scaling.

Suitable for

• Virtualization hosts and hyperconverged infrastructure
• Database servers and in-memory analytics
• High-performance computing (HPC) and batch processing
• Application servers and large-scale web services

Key specifications

• Cores: 32 physical cores
• Base frequency: 2.8 GHz
• Boost frequency: up to 3.7 GHz
• L3 cache: 256 MB
• Memory support: octa-channel DDR4 up to 3200 MHz
