Intel Xeon W5-3535X 20 Cores 40 Threads 4.8GHz E (LGA 4677) PK8071305501600 Workstation CPU

High-Performance Single-Socket Workstation CPU featuring PCIe 5.0 I/O density with the Intel Xeon W5-3535X / PK8071305501600

The Intel Xeon W5-3535X is a 4th Gen Sapphire Rapids-WS workstation processor for LGA4677 single-socket platforms, designed for engineering-focused compute where core throughput and deterministic latency matter. With 20 cores and 40 threads, it supports sustained multi-threaded performance while maintaining high turbo headroom for interactive CAD/CAM, EDA, and content creation pipelines.

For platform architecture, the Intel Xeon W5-3535X pairs DDR5 memory up to 4800 MT/s with ECC support and up to 4TB capacity to stabilise large working sets in simulation, CPU rendering, and virtualised lab environments. PCIe 5.0 expansion with up to 112 lanes enables dense GPU, NIC, and NVMe topologies without oversubscription, aligning the CPU with modern workstation storage tiers and high-bandwidth accelerator workflows. As the Intel Xeon W5-3535X provides no integrated graphics, deployments should plan for a discrete GPU where display or GPU compute is required.

Why Choose the Intel Xeon W5-3535X?

The Intel Xeon W5-3535X delivers an enterprise-friendly balance of compute density, memory scale, and PCIe 5.0 connectivity in a single-socket footprint, reducing platform complexity while preserving expansion headroom. For teams standardising on W790-based workstations, the Intel Xeon W5-3535X supports predictable scaling for mixed interactive and batch workloads, with VT-x, VT-d, and VT-rp enabling efficient device assignment and isolation for local virtualisation stacks.

Intel engineering for Sapphire Rapids-WS emphasises platform reliability, ECC-aware memory operation, and broad ecosystem validation across professional components. The Intel Xeon W5-3535X fits modern data centre and lab standards by enabling high-throughput I/O fabrics, NVMe-centric storage layouts, and controlled upgrade paths within LGA4677 workstation designs.
