Intel Xeon 6 6766E 144-core server processor

The Intel Xeon 6 6766E is a 144-core, 144-thread server processor built for high-density compute. It targets data-centre operators running virtualised workloads, cloud services or scale-out applications that benefit from many efficient cores. Buyers needing fewer cores or higher single-thread frequency should look elsewhere.

FCLGA 4710 socket with eight-channel DDR5-6400

The chip drops into an FCLGA 4710 platform and drives eight channels of DDR5-6400 memory up to 4 TB total capacity. PCI Express 5.0 lanes and four UPI links at 24 GT/s handle I/O and two-socket scaling. Systems must provide a compatible socket, memory population and cooling for the 250 W thermal envelope.

250 W TDP with Sierra Forest E-core architecture

The 3 nm Sierra Forest design runs at a 1.9 GHz base frequency and can reach 2.7 GHz max turbo within a 250 W TDP. E-core density aims for high performance per watt in throughput-oriented tasks. Adequate airflow and heatsink capacity are required to sustain boost behaviour under sustained load.

Questions about this item

What is the thermal design power that will limit sustained performance under load?

The processor has a 250 W TDP, which defines the cooling capacity required to maintain its 1.9 GHz base frequency during continuous all-core workloads.

How much heat and power should I plan for when this CPU runs at full load all day?

At maximum sustained operation the chip draws 250 W, so the cooling solution and power delivery must handle that continuous thermal output without throttling.

Which motherboard socket and memory type must already be in place for this processor to function?

The CPU requires an FCLGA 4710 socket and DDR5 memory running at 6400 MT/s across eight channels to operate.
