Intel Xeon Gold 5418N 24c/48t 1.8GHz-3.8GHz 165W (PK8071305121701)

Intel Xeon Gold 5418N — Technical Overview and Performance Insights

The Intel Xeon Gold 5418N is a mid-range Sapphire Rapids processor designed for distributed cloud environments, data-intensive workloads and large-scale virtualization clusters. With 24 cores and 48 threads operating at a 1.8 GHz base clock and boosting up to 3.8 GHz, the CPU focuses on efficient parallelism and predictable throughput rather than extreme peak frequency.

The processor features 2 MB of L2 cache per core and a shared 45 MB L3 cache. This cache hierarchy improves stability and responsiveness in mixed workloads, including distributed streaming platforms, multi-tenant virtualization, analytics pipelines and large-scale telemetry ingestion systems.

Support for eight-channel DDR5 memory up to 4000 MT/s provides significantly higher bandwidth than DDR4 servers. This benefits memory-intensive environments such as Java microservice clusters, real-time analytics, ML inference gateways and distributed in-memory databases, ensuring that the 24-core configuration remains well fed under load.

The Xeon Gold 5418N offers 80 PCIe 5.0 lanes, enabling high-speed NVMe storage arrays, 100/200G NICs, SmartNICs, DPUs, FPGA accelerators and other modern peripheral components. This level of I/O flexibility makes it suitable for software-defined storage nodes, virtualization farms, network appliances and scale-out compute systems.

With a 165 W TDP, the processor strikes a balance between power efficiency and sustained multi-thread performance. It fits well into dense dual-socket 1U/2U systems and edge datacenters where thermal overhead is limited.

Overall, the Intel Xeon Gold 5418N offers a strong combination of high core density, DDR5 bandwidth and PCIe 5.0 expansion. It is well suited for organizations deploying cloud-native services, virtualization clusters, distributed compute workloads and high-throughput analytics environments.
