Server processor for dense compute

The Intel Xeon Gold 6416H is an 18-core server processor built on 10 nm process technology. It targets workloads that scale across many threads such as virtualization, database serving and high-performance computing clusters. The LGA 4677 socket and eight memory channels suit dual-socket or four-socket platforms needing high core density.

Sustained-load behaviour

Base frequency sits at 2.2 GHz with a max turbo of 4.2 GHz across the 36 threads. The 165 W thermal design power reflects continuous multi-core throughput rather than short bursts. A 45 MB shared L3 cache and eight-channel DDR5 4800 memory subsystem keep data close to the cores during prolonged calculation phases.

Platform checks before ordering

Verify that your motherboard implements the LGA 4677 socket and supports eight-channel DDR5 memory populated to the required capacity. Confirm the cooling solution is rated for 165 W sustained dissipation in your chassis airflow layout. Ensure the system BIOS includes the microcode revision needed for Sapphire Rapids silicon.

Questions about this item

How much heat does the 165 W TDP generate during continuous all-day operation?

The processor is rated at 165 W thermal design power, so sustained full-load operation will require a server-class cooler and chassis airflow rated for at least that level of heat dissipation.

What motherboard socket and memory type are required to install this CPU?

It fits only the LGA 4677 socket and requires DDR5 memory running at up to 4800 MT/s across eight channels for full bandwidth.

Will the 80 PCIe 5.0 lanes work with PCIe 3.0 or 4.0 add-in cards I already own?

Yes, PCIe 5.0 is backward compatible, so existing PCIe 3.0 or 4.0 cards will function at their native speeds while the processor provides up to 80 lanes total.
