24-core Xeon for dense compute

The Intel Xeon Gold 6418H delivers 24 cores and 48 threads at a 2.1 GHz base frequency with a 4.0 GHz maximum turbo. It targets servers that run heavily threaded workloads such as virtualisation, database serving and high-performance computing. The 10 nm Sapphire Rapids architecture provides 60 MB of L3 cache to keep large working sets close to the cores.

DDR5-4800 eight-channel memory and PCIe 5.0 limits

The integrated memory controller supports DDR5 at 4800 MT/s across eight channels for a maximum addressable capacity of 4 TB. PCI Express 5.0 provides up to 80 lanes for high-bandwidth accelerators, storage controllers and networking adapters. Systems that cannot populate all eight memory channels or that use PCIe 4.0 devices will not reach the theoretical peak bandwidth of this platform.

LGA 4677 socket and 185 W thermal design

The processor fits the LGA 4677 socket and carries a 185 W thermal design power without a bundled cooler. Builders must provision adequate airflow or liquid cooling and ensure the motherboard power delivery can sustain the rated load. The S4S scalability link enables four-socket configurations, so single-socket boards leave that interconnect unused.

Questions about this item

How do the 24 cores and 48 threads affect performance for virtualization workloads?

The 24 cores and 48 threads allow many virtual machines to run simultaneously with dedicated compute resources, reducing contention and improving density on a single socket.

What does the 4.0 GHz max turbo frequency deliver in a real server?

The 4.0 GHz max turbo frequency provides burst performance for single-threaded tasks and latency-sensitive applications when thermal headroom allows.

How does the PCI Express 5.0 interface with 80 lanes limit expansion options?

PCI Express 5.0 with 80 lanes supports high-bandwidth GPUs, storage and networking cards simultaneously without lane sharing bottlenecks.
