16-Core Xeon Gold 5218
The Intel Xeon Gold 5218 is a 16-core server processor built for data-centre and hybrid-cloud workloads. It delivers 32 threads through Hyper-Threading support and runs on the LGA 3647 platform using 14 nm Cascade Lake architecture.
2.3 GHz base with 3.90 GHz turbo
The operating frequency sits at 2.3 GHz and can reach a maximum turbo frequency of 3.90 GHz, defining the compute throughput available for demanding applications. This clock range, combined with 22 MB of L3 cache, determines whether the chip matches a specific performance envelope.
Six-channel memory and 48 PCIe 3.0 lanes
An integrated memory controller supports six channels at 2667 MHz, while the processor exposes up to 48 PCI Express 3.0 lanes for high-bandwidth I/O. The 125 W thermal design power sets the cooling requirement, and the LGA 3647 socket dictates the motherboard platform needed for deployment.

Questions about this item
What does the 2.3 GHz base clock mean for a server running steady workloads?
The processor runs at 2.3 GHz on all 16 cores under sustained load, giving predictable throughput for database or virtualization tasks without relying on turbo behaviour.
How does the PCIe 3.0 interface with 48 lanes affect expansion options?
PCIe 3.0 with 48 lanes provides high-bandwidth connectivity for multiple add-in cards such as storage controllers or network adapters in a dual-socket server board.
What cooler clearance and socket hardware does the LGA 3647 package require?
The LGA 3647 socket uses a narrow ILM retention mechanism and needs a heatsink rated for 125 W TDP with the matching mounting pattern for 1U or 2U server chassis.
