Intel Xeon W5-3435X 16-Core Server CPU
This Intel Xeon W5-3435X is a 16-core server processor with 32 threads and a 3.1 GHz base frequency. It fits the LGA 4677 socket and supports DDR5 4800 memory across eight channels. The 45 MB L3 cache and 112 PCIe 5.0 lanes suit multi-GPU or high-throughput storage workloads. The processor base power is 270 W with a maximum turbo power of 324 W.
Suited for multi-threaded workstations.
The 16 cores and 32 threads accelerate rendering, simulation and virtualization workloads that scale across many threads. Eight-channel DDR5 4800 support feeds memory-hungry applications. Builders who need higher single-thread frequency or lower power draw should consider other options. The 270 W base power demands robust cooling and a capable power supply.
LGA 4677 socket and 270 W base power define
This processor requires a motherboard with the LGA 4677 socket and a power delivery system rated for at least 270 W base power. The 324 W maximum turbo power requires matching VRM cooling. Memory must be DDR5 4800; other DDR generations will not function. Verify chassis clearance for the 72°C thermal specification before purchase.

Questions about this item
How can I verify the Xeon W5-3435X is running at its 3.1 GHz base frequency after installation?
Enter the BIOS or use a monitoring utility such as Intel Processor Diagnostic Tool; it should report 16 cores, 32 threads and a 3.1 GHz base clock on the LGA 4677 socket.
What comes in the box with the PK8071305082000 and what must I purchase separately?
The tray processor is supplied alone; you must buy a compatible LGA 4677 motherboard, DDR5 4800 memory modules and a cooler rated for 270 W base power separately.
Which memory configuration should I choose for the 8-channel controller on this 16-core Xeon?
Populate all eight channels with identical DDR5 4800 DIMMs to reach the 4 TB maximum capacity and full bandwidth.
