72-Core Xeon 6 Server Processor

The Intel Xeon 6944P is a 72-core server CPU built on the Granite Rapids architecture for two-socket platforms. It delivers 144 threads through Hyper-Threading support and a base frequency of 1.8 GHz. This processor targets dense compute workloads in enterprise data centres.

DDR5 6400 Memory Interface Limits

The integrated memory controller runs twelve channels of DDR5 at 6400 MT/s, capping total system capacity at 3TB. PCI Express 5.0 provides 96 lanes for high-speed I/O, while six UPI links at 24 GT/s handle socket-to-socket traffic in 2S configurations.

350-Watt Thermal Design Power

A 350W TDP defines the cooling requirement for sustained all-core operation at 3.1 GHz. No cooling device is included, so a compatible thermal solution must be sourced separately. The FCLGA 7529 socket and 3 nm process underpin the power envelope.

Questions about this item

Should I pick the 72-core Xeon 6944P or a lower-core model for dense virtualization?

The 72-core, 144-thread design with 432 MB L3 cache and 12-channel DDR5 6400 is built for maximum density; fewer cores reduce parallel capacity and memory bandwidth proportionally.

What does the 3.9 GHz max turbo actually deliver in a live server?

Single-thread bursts reach 3.9 GHz, while sustained all-core workloads run at 3.1 GHz across all 72 cores within the 350 W TDP envelope.

How does the PCIe 5.0 interface limit expansion on this platform?

The processor provides 96 lanes of PCIe 5.0, capping total bandwidth at that lane count; add-in cards and storage share this pool.
