Intel Xeon W7-3455 24c/48t 2.5GHz-4.8GHz 324W (PK8071305081800)

Intel Xeon W7-3455 — Advanced Workstation Engine for High-Fidelity Rendering, Scientific Modeling & Large-Scale Production Pipelines

The Intel Xeon W7-3455 belongs to the upper tier of the Sapphire Rapids workstation family, targeting creators, engineers and researchers who rely on deterministic performance under long-duration, compute-intensive workloads. With 24 cores and 48 threads, it offers a significant step up in throughput compared to the 20-core W7-3445, especially in rendering, scientific computing and real-time simulation tasks that scale efficiently across many threads.

At the architectural level, the Golden Cove cores deliver strong single-thread responsiveness required by CAD tools, DCC applications and engineering software that still depend heavily on per-core speed—examples include SOLIDWORKS, Revit, CATIA, Maya’s viewport, Unreal Engine editing and parametric modeling workflows. The high turbo ceiling of 4.8 GHz ensures fluid interaction even in scenes with complex geometry, procedural rigs or shader-heavy previews.

Where the W7-3455 stands out is in hybrid workloads that alternate between interactive single-thread phases and heavy parallel execution. CPU render engines like Arnold, Redshift (CPU mode), V-Ray, Corona and Houdini Mantra benefit from the increased core count, maintaining stable performance across multi-hour sequences. Scientific applications—including finite element solvers, CFD modules, numerical optimizers and biomedical modeling—also gain from the larger core pool and Sapphire Rapids’ improved memory architecture.

Memory bandwidth is a defining advantage of the Xeon W-series. With support for up to 8 channels of DDR5 (on corresponding W-790 boards) and capacities reaching several terabytes, the W7-3455 is capable of handling extremely large datasets. This is crucial in modern workflows where memory oversubscription becomes a bottleneck: volumetric effects, high-resolution point clouds, genome modelling, fluid partitions, ML dataset preprocessing and large engineering assemblies can operate without aggressive out-of-core penalties.

The processor integrates a substantial 67.5 MB L3 cache, reducing latency spikes during iterative solvers, shading graph computation, heavy mesh operations and parallelized compilers. In environments like Houdini FX, Blender Geometry Nodes, OpenFOAM or Abaqus explicit solvers, cache efficiency directly translates to more stable frame-to-frame and iteration-to-iteration timing.

PCI Express 5.0 support is essential for modern workstation deployments. With up to 112 lanes available in the platform, multi-GPU configurations become straightforward: RTX 6000 Ada, Radeon Pro W7800, compute accelerators, 100/200Gb NICs, FPGA cards and high-lane-count NVMe arrays can coexist without contention. This makes the W7-3455 ideal for hybrid render farms, AI inference nodes, post-production mastering studios and engineering teams using GPU-accelerated solvers.

The Xeon W7-3455 is especially well suited for film/VFX rendering and compositing pipelines; procedural and simulation-heavy workflows; high-capacity scientific and engineering workstations; multi-application studio environments requiring stability; and GPU-accelerated production setups with significant PCIe lane demands.

For teams seeking a workstation CPU that balances high multi-thread throughput with strong single-thread behavior and massive expansion capability, the Intel Xeon W7-3455 provides a highly reliable foundation for demanding production environments.
