Intel Xeon W7 3445

High-Density Workstation and Entry Server CPU Platform with the Intel Xeon W7-3445 (PK8071305081900) on LGA4677

The Intel Xeon W7-3445 is a 4th Gen Sapphire Rapids workstation and entry server processor for the LGA4677 socket on the W790 platform, designed for single-socket systems that need strong per-core performance alongside scalable I/O. With 20 cores and 40 threads, the Intel Xeon W7-3445 supports CPU-bound engineering and content pipelines while retaining the isolation and control features expected in enterprise-class deployments.

Built around a DDR5 ECC memory architecture, the Intel Xeon W7-3445 enables high-capacity configurations up to 4TB (platform dependent) with consistent error protection for long-running render, simulation, and virtualization tasks. PCIe 5.0 connectivity with up to 112 lanes (system implementation dependent) aligns the Intel Xeon W7-3445 with I/O-dense builds, including multi-NVMe storage tiers and multiple accelerators, reducing contention in mixed compute and storage workflows. As a tray CPU (no cooler), it integrates into engineered thermal solutions appropriate for its 324W TDP.

Why Choose the Intel Xeon W7-3445?

The Intel Xeon W7-3445 delivers a practical density-to-performance balance for 1S platforms where memory footprint, PCIe expansion, and virtualization controls must scale without moving to multi-socket complexity. The Intel Xeon W7-3445 supports enterprise reliability through ECC memory enablement and platform features such as Intel VT-x, VT-d, and EPT for controlled lab virtualization, small application servers, and secure device passthrough.

Intel’s Xeon workstation and server engineering prioritizes predictable platform behavior, broad ecosystem validation, and long lifecycle alignment with modern data centre standards, enabling consistent firmware, driver, and management integration across W790-based deployments.

Key Applications:

CAD and CAE workstations
CPU-bound rendering and content creation
Virtualization labs and test environments
Small database and application servers
I/O-dense multi-NVMe storage nodes

At Happyware - Server Hardware you benefit from non-binding offers tailored to your build requirements and an extended warranty up to 6 years, supporting controlled rollout planning for Intel Xeon W7-3445 based workstation or entry server fleets.
