Intel Xeon Gold 5220 18-Core Server Processor
The Intel Xeon Gold 5220 is an 18-core server processor with a 2.2 GHz base frequency and 3.9 GHz max turbo frequency. It supports 36 threads through Hyper-Threading technology and includes 24.75 MB of L3 cache. Built on 14 nm process technology, it has a 125 W thermal design power and is designed for multi-socket server deployments.
LGA 3647 Socket with 48 PCIe 3.0 Lanes
This CPU fits the LGA 3647 socket and provides 48 lanes of PCI Express 3.0 connectivity for high-speed I/O expansion. The integrated memory controller runs six channels at 2667 MHz, freeing board space by eliminating the need for external memory buffers. A compatible server chassis and cooling solution rated for the 125 W TDP are required for installation.
Intel Virtualization Technology Enabled
Intel Virtualization Technology is supported in hardware, allowing multiple isolated workloads to run on the same physical cores without additional software licensing. The 64-bit instruction set and 14 nm manufacturing enable dense compute clusters for cloud and enterprise applications. Workloads requiring accelerator cards or specialised instruction sets not listed here are not addressed by this processor.

Questions about this item
What limits sustained performance under heavy load?
The 125 W thermal design power and 87 °C thermal specification define the sustained power and temperature ceiling.
How much heat and noise should I expect when the processor runs all day?
A 125 W TDP means the cooler must dissipate that heat continuously; fan noise depends on the cooling solution chosen.
Which socket and memory controller does the CPU need to operate?
It requires an LGA 3647 socket and uses a six-channel integrated memory controller rated for 2667 MHz.
