AMD EPYC 7453 28c/56t 2.75GHz-3.45GHz 225W (100-000000319)

AMD EPYC 7453 Server CPU

Positioning and role in the EPYC 7003 lineup

AMD EPYC 7453 is a 3rd Gen EPYC “Milan” processor positioned as a high-core-count, balanced-performance SKU for enterprise and cloud infrastructure. It targets environments that need more parallel compute capacity than 24-core parts, while maintaining predictable behavior, strong memory bandwidth, and full EPYC platform capabilities. Within the EPYC 7003 family, the 7453 is commonly selected for production systems that run sustained, multi-threaded workloads at scale.

Core configuration, frequency behavior, and execution profile

The processor provides 28 cores and 56 threads, operating at a 2.75 GHz base clock with boost frequencies up to 3.45 GHz. This configuration emphasizes throughput and steady parallel execution rather than aggressive single-core boost. In practice, EPYC 7453 performs well in workloads that scale across many threads, such as virtualization, large application servers, distributed services, and data-processing pipelines.

Zen 3 cores deliver improved instructions-per-clock and more consistent latency behavior compared to previous EPYC generations. This helps maintain stable performance under mixed and sustained workloads, which is critical for long-running enterprise services.

Cache architecture and memory access characteristics

EPYC 7453 includes 64 MB of L3 cache, which provides a functional cache-to-core ratio for throughput-oriented workloads. While its cache capacity is lower than frequency-optimized or cache-specialized SKUs, it is sufficient for many enterprise applications that rely primarily on parallel execution and memory bandwidth rather than large cache residency.

The processor supports DDR4-3200 memory across 8 memory channels, a key strength of the EPYC platform. With symmetric DIMM population, EPYC 7453 delivers high aggregate memory bandwidth per socket, making it suitable for memory-intensive workloads, large VM densities, and data services that benefit from sustained memory throughput.

I/O capabilities and platform integration

EPYC 7453 supports PCI Express 4.0 with up to 128 lanes per socket. This extensive I/O capability allows dense NVMe storage configurations, high-speed networking, and flexible expansion without external PCIe switches. As a result, the processor integrates well into storage-heavy, network-intensive, and software-defined infrastructure designs.

The CPU uses the SP3 socket and supports both single-socket and dual-socket server configurations, depending on platform validation. This flexibility allows EPYC 7453 to be deployed in a wide range of enterprise server architectures.

Power characteristics and deployment considerations

EPYC 7453 is rated at 225 W TDP, reflecting its higher core count and sustained throughput focus. Adequate server-grade cooling and airflow are required to maintain stable performance under continuous load. When deployed in properly designed platforms, the processor delivers predictable behavior suitable for always-on enterprise environments.

Ideal use cases and selection guidance

EPYC 7453 is best suited for workloads that benefit from higher core density and steady parallel performance. Typical use cases include virtualization hosts with large VM counts, cloud and hosting infrastructure requiring scalable throughput, enterprise application servers and middleware platforms, and data-processing and analytics workloads with strong parallelism. It is an effective choice when workloads scale efficiently across many threads and require full EPYC memory and I/O capabilities without the need for frequency-optimized or cache-specialized processors.
