16-core Xeon for workstation workloads

The Intel Xeon W5-3435X is a 16-core, 32-thread server processor built for professional workstations. It runs at a 3.10 GHz base frequency with a maximum turbo of 4.70 GHz. The chip provides 45 MB of L3 cache and supports up to 4 TB of DDR5-4800 memory across eight channels. It fits the LGA 4677 socket and has a 324 W thermal design power.

Eight-channel DDR5 and 112 PCIe 5.0 lanes

The integrated memory controller drives eight channels of DDR5-4800, giving bandwidth for large datasets and multi-threaded applications. The platform exposes up to 112 lanes of PCI Express 5.0 for high-speed storage, GPUs and networking cards. Hyper-Threading and virtualisation support are included for dense container or VM deployments. No cooler is bundled in the box.

Verify LGA 4677 motherboard and 324 W cooling

Confirm your motherboard uses the LGA 4677 socket and a chipset that enables the full eight-channel memory controller and 112 PCIe 5.0 lanes. The 324 W TDP requires a cooler and chassis airflow rated for that heat load. Ensure the power delivery subsystem can sustain the processor at its 4.70 GHz turbo frequency. Memory must be DDR5; earlier generations are not compatible.

Questions about this item

What cooling capacity does the 324 W TDP require for continuous operation?

A cooler rated for at least 324 W of heat dissipation is needed to maintain base clocks under sustained load, otherwise the processor will throttle to stay within its thermal limit

Will the 112 PCIe 5.0 lanes become a bottleneck before the 16 cores do?

The 112 lanes provide up to 112 GB/s of aggregate bandwidth, so most multi-GPU or storage arrays saturate the 16 cores before exhausting the lane budget

How loud and hot does the boxed cooler run during an all-day render at 3.1 GHz base clock?

No boxed cooler is included; a 324 W TDP demands a high-end tower or liquid cooler that will move significant air and produce audible fan noise under full load
