AMD EPYC 9384X 32c/64t 3.1GHz-3.9GHz 320W (100-000001256)

AMD EPYC 9384X Server CPU

Positioning within the EPYC 9004 lineup

AMD EPYC 9384X is a Zen 4–based EPYC processor from the X-series with 3D V-Cache, designed for workloads where cache capacity and memory-latency reduction are primary performance drivers. Within the EPYC 9004 “Genoa” family, the 9384X targets enterprise and technical environments that process large, frequently reused datasets and benefit more from cache residency than from higher core counts alone.

Core configuration and execution profile

The processor provides 32 cores and 64 threads, operating at a 3.1 GHz base frequency with boost clocks up to 3.9 GHz. This configuration balances solid per-core performance with a cache-centric design. In production environments, EPYC 9384X performs well in applications that combine latency-sensitive execution paths with repeated access to large working sets, where reducing memory round trips has a direct impact on throughput and response time.

Compared to higher-frequency F-series models, the EPYC 9384X prioritizes cache efficiency and predictable performance under sustained load, which is often more valuable for long-running enterprise and technical workloads.

3D V-Cache architecture and workload impact

A defining feature of EPYC 9384X is its 768 MB of L3 cache, enabled by AMD’s 3D V-Cache stacking technology. This large cache dramatically increases the amount of data that can be served at cache latency, reducing pressure on main memory and improving performance consistency.

Workloads that commonly benefit include databases with large indexes and hot datasets, analytics and query-heavy enterprise platforms, electronic design automation and simulation, and scientific and technical computing with iterative data access. When the active working set fits largely within cache, performance gains can be significant, especially in scenarios where memory latency is a limiting factor.

Memory subsystem characteristics

EPYC 9384X supports DDR5-4800 memory across 12 memory channels, delivering very high aggregate memory bandwidth per socket. While the massive L3 cache reduces reliance on DRAM for many workloads, proper memory configuration remains essential. Balanced DIMM population and sufficient capacity help prevent cache eviction and ensure stable behavior during sustained production use.

The combination of 3D V-Cache and the EPYC 9004 memory subsystem provides a strong foundation for data-intensive workloads that require both low latency and high throughput.

I/O capabilities and platform integration

The processor supports PCI Express 5.0 with up to 128 lanes, enabling next-generation NVMe storage, high-speed networking, and accelerator connectivity without external PCIe switches. This allows architects to design compact, high-performance systems that combine fast storage access with extreme cache capacity and modern I/O bandwidth.

EPYC 9384X uses the SP5 socket and supports dual-socket configurations, enabling systems with very high aggregate cache, memory capacity, and I/O resources for demanding enterprise and technical environments.

Power envelope and deployment considerations

EPYC 9384X is rated at 320 W TDP, reflecting the power requirements of its cache-heavy design and relatively high operating frequencies. Deployment requires enterprise-grade cooling and chassis designed for sustained high power density. In properly engineered systems, the processor delivers consistent performance under continuous load, which is essential for mission-critical production workloads.

Ideal use cases and selection guidance

EPYC 9384X is best suited for environments where large cache capacity directly translates into measurable performance benefits. Typical use cases include high-performance databases and analytics platforms, simulation and modeling workloads, technical computing with cache-sensitive access patterns, and enterprise systems where predictable latency is critical. For workloads dominated by massive parallelism, higher core-count EPYC models may be more appropriate. EPYC 9384X should be selected when profiling confirms that cache misses and memory access latency are the primary constraints on performance.
