AMD EPYC 7443 Server Processor – 24 Cores / 48 Threads, 2.85 GHz, 128 MB L3, Socket SP3, Tray

The AMD EPYC 7443 is a server-class processor operating at a base frequency of 2.85 GHz with a boost up to 4 GHz and 128 MB of L3 cache. Designed for data center and enterprise workloads, this CPU offers 24 physical cores and compatibility with Socket SP3 motherboards. It supports octa-channel DDR4 memory at up to 3200 MHz, providing the memory bandwidth necessary for virtualization, database processing, and high-throughput computing tasks.

Advantages

The EPYC 7443 combines a high core count and a large L3 cache to deliver consistent multi-threaded performance across demanding server applications. Its support for octa-channel DDR4 memory and elevated memory clock rates improves throughput and reduces latency for memory-intensive tasks. Socket SP3 compatibility simplifies deployment in many server platforms, while the 4 GHz boost frequency enables strong single-threaded performance when required.

Suitable for

• Virtualization hosts and hyperconverged infrastructure
• Database servers and in-memory databases
• High-performance computing (HPC) and scientific workloads
• Web and application servers handling concurrent requests
• Enterprise analytics and batch processing

Key specifications

• Base frequency: 2.85 GHz
• Maximum boost frequency: 4 GHz
• Cores: 24 physical cores
• Cache: 128 MB L3 cache
• Memory support: octa-channel DDR4 up to 3200 MHz
