Intel Xeon W7-3465X 28-core 2.5 GHz server processor PK8071305081700

28-core Xeon for multi-threaded workloads

The Intel Xeon W7-3465X is a 28-core, 56-thread server processor built for workstations that run heavily parallel applications. It operates at a 2.5 GHz base frequency and can reach 4.80 GHz with Intel Turbo Boost Max Technology 3.0. The 75 MB L3 cache and 7 nm manufacturing help sustain throughput across many simultaneous threads. Buyers who need only lightly threaded performance or lower core counts will not benefit from this design.

DDR5-4800 eight-channel memory and PCIe 5.0 limits

The integrated memory controller supports DDR5 at 4800 MT/s across eight channels for a maximum capacity of 4 TB. Memory bandwidth scales with populated channels; partially filled configurations reduce peak throughput. The CPU provides 112 lanes of PCI Express 5.0 for GPUs, storage and networking add-in cards. Platforms that cannot supply eight memory channels or that limit PCIe lane allocation will constrain the processor’s I/O potential.

Verify LGA 4677 socket.

This processor requires a motherboard with an LGA 4677 socket and a workstation-class chipset that enables the full eight-channel memory and 112-lane PCIe topology. The cooling solution must dissipate a 300 W base power and up to 360 W under maximum turbo. The physical package measures 3.1 by 2.2 inches, so the cooler mounting pattern and case clearance must accommodate those dimensions. Systems without adequate VRM phases or firmware support for Sapphire Rapids will not boot.
