AMD EPYC 9455, AMD EPYC, Socket SP5, 3.15 GHz, 4.4 GHz, 256 MB Processor

Imagine a server that never slows down even when you run dozens of AI models at once. The AMD EPYC 9455 is a 48-core, 96-thread processor built for the most demanding data-center workloads. It fits into the Socket SP5 platform and delivers up to 4.4 GHz boost speed with a massive 256 MB L3 cache. If your current CPU is choking on heavy virtualization, AI inference, or large database queries, you need a chip that can keep up without adding more racks.

Many enterprises struggle with limited compute density, high power bills, and slow response times when their servers are overloaded. This matters because every extra rack means more floor space, more cooling, and higher licensing costs. The AMD EPYC 9455 solves these issues by packing 48 Zen 5 cores into a single socket, offering up to 86 % fewer racks for the same workload, and delivering industry-leading integer performance while staying energy efficient.

Benefits

• Faster AI inference lets you serve more requests per second, reducing latency for end users.
• High memory bandwidth (576 GB/s) speeds up large data sets, so analytics finish in minutes instead of hours.
• 48 cores and 96 threads enable dense virtualization, allowing many VMs on one server and cutting licensing fees.
• Configurable TDP from 240 W to 300 W lets you balance power use and performance for your data-center budget.
• PCIe 5.0 with 128 lanes gives ample room for GPUs, NVMe storage, and networking cards, future-proofing your build.

Usages

The EPYC 9455 fits perfectly in cloud-hosted virtual machines, high-performance computing clusters, and AI inference servers. It powers database engines that need fast transaction processing, runs container workloads that demand many cores, and acts as the host CPU for GPU-accelerated training rigs. Whether you run a SaaS platform, a video-streaming service, or a fraud-detection engine, this processor gives you the headroom to scale without redesigning your hardware.
