AMD EPYC 7573X 32c/64t 2.8GHz-3.6GHz 280W (100-000000506)

AMD EPYC 7573X Server CPU

Positioning and role in the EPYC 7003 lineup

AMD EPYC 7573X is a 3rd Gen EPYC “Milan” processor from the X-series with 3D V-Cache, created for workloads where cache capacity is the dominant performance factor. It targets enterprise and technical environments that operate on very large working sets and are constrained primarily by memory latency rather than raw compute frequency. Within the EPYC 7003 family, the 7573X represents a top-tier cache-focused solution for data-intensive production systems.

Core configuration, frequency behavior, and execution profile

The processor provides 32 cores and 64 threads, operating at a 2.8 GHz base clock with boost frequencies up to 3.6 GHz. Compared to frequency-optimized F-series parts, the EPYC 7573X runs at more conservative clock speeds, which is a deliberate trade-off to support its extremely large cache architecture. In practice, this design favors workloads where execution time is dominated by memory access patterns and cache efficiency rather than peak per-core frequency.

Zen 3 cores deliver strong instructions-per-clock and predictable scaling across threads, enabling the processor to perform consistently in parallel workloads that repeatedly access large shared datasets.

3D V-Cache architecture and workload impact

The defining feature of EPYC 7573X is its 768 MB of L3 cache, enabled by AMD’s 3D V-Cache technology. This massive cache significantly increases the amount of data that can be served directly from cache instead of DRAM. For professional workloads, this can lead to substantial performance improvements in scenarios such as analytics and query-heavy database platforms, in-memory and hybrid databases with large index structures, electronic design automation and simulation, and scientific and technical computing with cache-friendly access patterns.

When the active working set fits largely within cache, reduced memory latency and lower bandwidth pressure can deliver gains that outweigh differences in clock speed or core count.

Memory subsystem and capacity planning

EPYC 7573X supports DDR4-3200 memory across 8 memory channels, consistent with the EPYC 7003 platform. Although 3D V-Cache reduces reliance on DRAM for many workloads, correct memory configuration remains essential. Symmetric DIMM population and sufficient capacity help prevent paging and cache thrashing, ensuring stable performance during sustained operation.

The combination of very large L3 cache and high aggregate memory bandwidth provides predictable behavior for cache-optimized workloads running continuously in enterprise environments.

I/O capabilities and platform fit

The processor supports PCI Express 4.0 with up to 128 lanes per socket, enabling dense NVMe storage configurations and high-speed networking without external PCIe switches. This makes EPYC 7573X well suited for data platforms that require both fast storage access and extreme cache capacity.

The CPU uses the SP3 socket and is intended for single-socket server deployments, aligning with platform designs that prioritize cache density and per-socket performance efficiency.

Power characteristics and deployment considerations

EPYC 7573X is rated at 280 W TDP, reflecting the power requirements of its cache-heavy design and higher core count. Robust server-grade cooling and sufficient airflow are required to maintain stable operation under sustained load. In return, the processor delivers consistent performance for cache-sensitive workloads that would otherwise be limited by memory latency.

Ideal use cases and selection guidance

EPYC 7573X is best suited for environments where maximum cache capacity directly translates into performance gains. Typical use cases include large-scale analytics and query-heavy databases, simulation, modeling, electronic design automation, scientific computing, and high-value enterprise workloads where performance improvements justify a specialized CPU. For general-purpose virtualization or throughput-oriented scaling, non-X EPYC models are often more cost-effective. EPYC 7573X should be selected when profiling clearly shows cache misses and memory latency as the primary bottlenecks.
