28-core Xeon for multi-threaded workloads

The Intel Xeon W7-3465X is a 28-core server processor built for workstations that run heavy multi-threaded applications such as rendering, simulation and virtualization. It provides 56 threads and a 75 MB L3 cache to keep large data sets close to the cores. The LGA 4677 socket targets professional platforms that need high core counts and memory bandwidth.

Sustained load behaviour with 360 W turbo

Under continuous load the processor operates at a 300 W base power and can raise consumption to 360 W when Turbo Boost 2.0 lifts clocks to 4.60 GHz across active cores. Intel Turbo Boost Max 3.0 can push a single core to 4.80 GHz for burst tasks. Cooling and power delivery must handle the 360 W maximum turbo power for extended periods.

Platform checks before ordering

Verify that your motherboard uses the LGA 4677 socket and supports a 360 W thermal design. The memory controller runs eight channels of DDR5 at 4800 MT/s, so populate all eight slots for full bandwidth. The CPU exposes 112 PCIe 5.0 lanes; confirm your board routes the lanes you need for GPUs, storage or networking.

Questions about this item

How much heat does the 360 W maximum turbo power generate during sustained all-day workloads?

The processor has a base power of 300 W and a maximum turbo power of 360 W, so sustained heavy loads will draw up to 360 W and require a cooler rated for that thermal design power.

Which DDR5 memory speed and capacity does the integrated controller support for this 28-core CPU?

The integrated memory controller runs DDR5 at 4800 MT/s across eight channels and supports up to 4 TB of total memory capacity.

Will my existing PCIe 4.0 expansion cards work with the 112 lanes of PCIe 5.0 on this processor?

PCIe 5.0 is backward compatible, so PCIe 4.0 cards will operate at their rated speeds using the available 112 lanes.
