Intel Xeon Gold 6444Y 16-core server processor
The Intel Xeon Gold 6444Y is a 16-core, 32-thread server processor built for dual-socket platforms. It targets data-centre workloads that demand high core counts and large memory capacity. The LGA 4677 socket and 270 W thermal design power require robust server-grade cooling and power delivery.
Sustained load behaviour with 45 MB L3 cache
Under continuous load the processor maintains a 3.6 GHz base frequency across all 16 cores. The 45 MB L3 cache helps keep frequently used data close to the execution units during extended compute tasks. Max turbo frequency reaches 4.0 GHz when thermal headroom allows.
Build quality and platform connectivity
The 10 nm Sapphire Rapids die integrates an eight-channel DDR5 4800 memory controller supporting up to 4 TB per socket. Eighty PCI Express 5.0 lanes provide high-bandwidth I/O for storage and networking cards. A separate cooling solution must be sourced for the LGA 4677 package.

Questions about this item
How much heat does the 270 W TDP generate during continuous 24/7 operation?
The processor has a 270 W thermal design power, so sustained full-load work will require a server-grade cooler or liquid loop rated for at least that heat output.
Which memory modules and motherboard socket are required for the Xeon Gold 6444Y?
You need a motherboard with an LGA 4677 socket and DDR5 4800 RDIMMs or LRDIMMs; the integrated controller supports eight channels up to 4 TB total capacity.
Will the 80 PCIe 5.0 lanes work with older PCIe 3.0 or 4.0 add-in cards?
Yes, the 80 lanes are backward compatible, so existing PCIe 3.0 or 4.0 cards will operate at their native speeds while newer PCIe 5.0 devices can use the full bandwidth.
