AMD EPYC 9845 160 Cores 320 Threads 3.7GHz SP5 100-000001458 Server CPU

High-Density Data Centre Server CPU featuring Zen 5c efficiency with the AMD EPYC 9845 (SKU 100-000001458)

The AMD EPYC 9845 is a Turin Dense Zen 5c processor for the SP5 (LGA6096) platform, engineered for high-core-count consolidation where per-rack throughput and predictable latency matter. With 160 cores and 320 threads, the AMD EPYC 9845 targets dense virtualisation, private cloud nodes, and CPU-heavy services that scale horizontally while still needing strong single-socket efficiency.

The AMD EPYC 9845 integrates a 12-channel DDR5 memory subsystem up to 6000 MT/s, enabling large memory footprints for in-memory analytics and scale-up database tiers, with platform-dependent capacity up to 6 TB. For expansion, the platform exposes up to 128 PCIe 5.0 lanes, aligning the CPU with high-bandwidth NVMe storage fabrics, DPUs/NICs, and accelerator-adjacent architectures without oversubscribing I/O. This balance of memory bandwidth and PCIe 5.0 connectivity supports modern composable designs and storage-dense servers where throughput per socket is the primary optimisation goal.

Why Choose the AMD EPYC 9845?

The AMD EPYC 9845 provides a density-to-performance profile suited to 1P deployments while remaining compatible with 2S platform designs, simplifying standardisation across clusters. The core-rich Zen 5c approach improves consolidation ratios, and enterprise features such as ECC support and AMD Infinity Guard reinforce reliability and secure multi-tenant operation at scale.

AMD designs EPYC processors with a data-centre-first focus on platform longevity, validated enterprise silicon features, and consistent support for contemporary standards such as DDR5 and PCIe 5.0, enabling predictable integration into modern server and storage architectures.

Key Applications:

• Dense virtualisation and private cloud
• High-core-count VDI and session hosts
• In-memory databases and analytics
• CPU compute with large memory footprints
• NVMe storage and I/O-dense nodes
