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.

Questions about this item

Will my current DDR5-4400 modules run at their rated speed with the Xeon Gold 5418N?

Yes, the integrated memory controller is specified for DDR5 4400, so compatible modules will operate at that speed across the 8 channels.

How can I confirm the 24 cores and 48 threads are active after installation?

Check the OS task manager or run lscpu; both should report 24 physical cores and 48 logical processors at the 1.8 GHz base frequency.

Does the PK8071305121701 box include a cooling solution or must I buy one separately?

The processor is sold without a cooling device; a compatible LGA 4677 cooler rated for at least 165 W TDP must be purchased separately.
