Xeon Silver 4216 16-Core Server Processor

The Intel Xeon Silver 4216 is a 16-core, 32-thread server CPU built on 14 nm Cascade Lake architecture. It targets midsized and growing IT organisations running data-centre compute, network, and storage workloads. The processor fits the LGA 3647 socket and supports dual-socket scalability for expanded capacity.

100W TDP with DDR4 2400 Six-Channel Memory

At a 100W thermal design power the chip runs at a 2.1 GHz base frequency and reaches 3.2 GHz max turbo. The integrated memory controller drives six channels of DDR4 2400 memory up to 1 TB total capacity. PCI Express 3.0 lanes handle I/O connectivity for storage and networking cards.

Boxed Processor Includes Standard Cooler

The BX806954216 boxed package ships with an Intel-qualified heatsink and fan assembly matched to the 100W thermal envelope. No additional software licences or management utilities are bundled; virtualisation and security features operate through standard platform firmware and operating-system support.

Questions about this item

How do I install the BX806954216 processor into an LGA 3647 socket?

Align the notches on the CPU with the socket keys, lower it straight down without pressure, then close the load plate and secure the heatsink according to the motherboard manual.

What maintenance or replacement will the BX806954216 need over time?

The processor itself has no serviceable parts; plan to replace thermal paste every few years and verify the cooling solution keeps the 100W TDP within safe temperatures.

What limit appears first when the Xeon Silver 4216 runs sustained workloads?

The 100W thermal design power sets the sustained ceiling; the 2.1 GHz base frequency is the guaranteed floor under continuous all-core load.
