AMD EPYC 7443P 24c/48t 2.85GHz-4.0GHz 200W (100-000000342)

AMD EPYC 7443P Server CPU

Positioning and role in the EPYC 7003 lineup

AMD EPYC 7443P is a 3rd Gen EPYC “Milan” processor optimized specifically for single-socket enterprise servers. The “P” designation indicates a SKU designed to deliver maximum value and performance in 1P systems, eliminating dual-socket capability in exchange for lower platform cost and simplified system design. Within the EPYC 7003 lineup, the 7443P targets organizations that want strong multi-core performance, full EPYC memory and I/O capabilities, and predictable behavior in cost-efficient single-socket deployments.

Core configuration, frequency behavior, and execution profile

The processor features 24 cores and 48 threads, running at a 2.85 GHz base frequency with boost clocks up to 4.0 GHz. This configuration provides a balanced execution profile that favors sustained throughput while still maintaining solid single-thread responsiveness for mixed enterprise workloads. EPYC 7443P performs well in environments where applications scale across many threads but still require consistent latency characteristics, such as virtualized platforms, containerized services, and enterprise middleware.

Zen 3 cores deliver improved instructions-per-clock and more efficient cache behavior compared to previous EPYC generations, contributing to stable performance under continuous and mixed-load conditions.

Cache architecture and memory access characteristics

EPYC 7443P includes 128 MB of shared L3 cache, offering a balanced cache-to-core ratio suitable for general-purpose server workloads. This cache capacity helps reduce memory access latency and improves consistency for virtual machines and container workloads that repeatedly access shared data structures.

The processor supports DDR4-3200 memory across 8 memory channels, which remains a key advantage of the EPYC platform even in single-socket configurations. With symmetric DIMM population, EPYC 7443P delivers high aggregate memory bandwidth per socket, making it suitable for memory-intensive applications and dense virtualization environments.

I/O capabilities and platform integration

EPYC 7443P supports PCI Express 4.0 with up to 128 lanes per socket, enabling dense NVMe storage, high-speed networking, and flexible expansion without external PCIe switches. This I/O capacity allows system architects to design storage-heavy or network-intensive single-socket servers without compromising connectivity.

The processor uses the SP3 socket and is limited to single-socket systems, which simplifies platform validation and reduces total system cost while retaining enterprise-grade connectivity and memory bandwidth.

Power characteristics and deployment considerations

EPYC 7443P is rated at 200 W TDP, reflecting its balance of core count, frequency, and sustained performance capability. Proper server-grade cooling and airflow are required to maintain consistent operation under continuous load. In return, the processor delivers predictable performance suitable for always-on enterprise environments and production workloads.

Ideal use cases and selection guidance

EPYC 7443P is best suited for organizations standardizing on single-socket server designs. Typical use cases include virtualization hosts optimized for 1P platforms, container orchestration nodes with steady concurrency, enterprise application and middleware servers, and cloud and hosting environments focused on cost-efficient scaling. It is an effective choice when workloads benefit from 24 cores, full EPYC memory and I/O bandwidth, and predictable performance without the need for dual-socket scalability.
