Intel Xeon Gold 5418N PK8071305121701 24-core 1.8 GHz server processor

Xeon Gold 5418N 24-core server processor

The Intel Xeon Gold 5418N is a 24-core, 48-thread server CPU built on 10 nm Sapphire Rapids architecture for dual-socket platforms. It targets compute-dense workloads such as virtualization, database serving and high-performance computing clusters. The LGA 4677 socket and 165 W thermal design power require compatible server infrastructure and robust cooling. Buyers needing single-socket desktop operation or lower power envelopes should look elsewhere.

45 MB L3 cache and 4 TB DDR5-4400 capacity

Eight memory channels feed up to 4 TB of DDR5-4400, giving ample headroom for in-memory databases and large virtual-machine fleets. The 45 MB shared L3 cache reduces latency on multi-threaded code, while the 3.8 GHz max turbo frequency lifts burst performance. Workloads that exceed 4 TB total memory or demand more than 24 cores per socket will hit the ceiling of this part.

LGA 4677 socket with 80 PCIe 5.0 lanes

The processor drops into an LGA 4677 socket and exposes 80 lanes of PCIe 5.0 for high-bandwidth storage, networking and accelerator cards. No cooling device is included, so integrators must provision a server-grade heatsink or liquid loop rated for 165 W. Systems limited to fewer PCIe lanes or older DDR generations cannot use this processor.
