Workstation processor with 20 cores
The Intel Xeon W5-3535X is a 20-core, 40-thread server CPU built for single-socket workstations that run heavy multi-threaded workloads such as rendering, simulation and virtualization. It operates at a 2.9 GHz base frequency and can reach 4.8 GHz with Intel Turbo Boost Max Technology 3.0.
LGA 4677 platform with eight DDR5 channels
The processor mounts in an LGA 4677 socket and provides an integrated memory controller rated for DDR5 4800 across eight channels, supporting up to 4 TB of system memory. It also exposes 112 PCI Express 5.0 lanes for high-bandwidth add-in cards and storage, while scalability is limited to a single-socket configuration.
300 W base power with 360 W maximum turbo
Thermal design power is rated at 300 W and can rise to 360 W under maximum turbo conditions, so a robust cooling solution is required; no cooler is included in the box. The 10 nm manufacturing process and 52.5 MB L3 cache help manage heat density during sustained all-core operation.

Questions about this item
What is the 300 W thermal design power limit under sustained full-core workloads?
The processor has a 300 W base thermal design power that becomes the sustained ceiling once all 20 cores run continuously at load.
How much heat and fan noise should I expect from the 360 W max turbo power during all-day rendering?
At the 360 W max turbo power the chip can draw significantly more heat than the 300 W base, so a high-capacity cooler rated for at least 360 W is required to keep temperatures and fan speed under control.
Which LGA 4677 motherboard and DDR5-4800 memory must I already have for this Xeon W5-3535X to operate?
You need a workstation board with an LGA 4677 socket, an 8-channel DDR5-4800 memory controller and a power-delivery system capable of 360 W peak for the 20-core 2.9 GHz processor.
