AMD EPYC 9475F 48c/96t 3.65GHz-4.8GHz 400W (100-000001143)

AMD EPYC 9475F (Turin) High-Frequency Server CPU Overview

Positioning and intended workload profile

AMD EPYC 9475F is a 5th Gen EPYC 9005-series processor (Zen 5, codename Turin) created for frequency-critical, latency-sensitive server workloads. The “F” designation identifies SKUs tuned for higher clocks, making this model a strong choice where per-core performance and fast response times matter more than maximizing core count. With 48 cores, EPYC 9475F targets demanding enterprise applications that scale well but still rely on strong single-thread execution.

Core configuration and execution behavior

The processor features 48 cores and 96 threads, operating at a 3.65 GHz base frequency with boost clocks up to 4.8 GHz. This clock profile places EPYC 9475F among the fastest Zen 5 EPYC CPUs in terms of per-core speed. In real deployments, this translates into lower tail latency and improved responsiveness for workloads where critical paths cannot be fullyparallelized.

Compared to standard balanced SKUs, the 9475F sacrifices some power efficiency to deliver higher sustained frequency, which is often a deliberate and valuable trade-off in performance-sensitive tiers.

Cache configuration and data locality

EPYC 9475F includes 256 MB of L3 cache, providing sufficient cache capacity to support high-frequency execution across 48 cores without excessive memory traffic. This cache size helps reduce stalls caused by memory access, particularly in workloads with moderate data locality such as transaction processing, real-time analytics, and latency-sensitive services.

While it is not a cache-optimized X-series model, the cache-to-core balance is well matched to its frequency-focused design.

Memory subsystem and bandwidth considerations

The processor supports DDR5-6400 memory across 12 memory channels, delivering very high aggregate bandwidth per socket. This wide memory interface ensures that fast cores remain fed with data under load and prevents memory bandwidth from becoming a limiting factor as utilization increases.

For production systems, memory should be populated evenly across channels and validated according to the server vendor’s QVL to maintain stable latency and predictable throughput.

I/O capabilities and platform integration

EPYC 9475F provides PCI Express 5.0 connectivity with up to 128 lanes, enabling high-performance NVMe storage, low-latency networking, and accelerator attachment without external PCIe switches. This I/O capacity is particularly valuable in architectures where fast CPUs must be paired with equally fast storage and network paths.

The processor uses the SP5 socket and supports dual-socket configurations, allowing architects to scale performance further when application design benefits from multiple sockets.

Power envelope and operational planning

With a 400 W TDP, EPYC 9475F sits at the high end of the power spectrum for air-cooled server CPUs. This power envelope reflects its high-frequency design and requires careful attention to cooling and airflow. Server platforms intended for this CPU typically use advanced heatsinks, optimized airflow paths, or liquid cooling in dense environments.

When thermal requirements are met, the processor delivers stable high-frequency performance under sustained load, which is essential for latency-critical services.

Ideal use cases and selection guidance

EPYC 9475F is best suited for latency-sensitive and frequency-dependent workloads. Typical use cases include databases and transactional systems with critical single-thread paths, low-latency analytics and real-time data processing, high-performance middleware and application servers, and compute tiers where response time is more important than maximum consolidation. For environments focused on energy efficiency or extreme parallelism, balanced or higher core-count models may be more appropriate. EPYC 9475F is an excellent choice when the primary objective is to deliver maximum Zen 5 per-core performance within the EPYC platform.
