Intel Xeon W-3175X Review
The Intel Xeon W-3175X is a 28-core, 56-thread workstation processor built on Skylake architecture, running a 3.1 GHz base clock that boosts up to 4.5 GHz on select cores within a 255 Watt TDP on the LGA 3647 socket.
This chip is Intel's answer to AMD's high-core-count Threadripper lineup, targeting extreme workstation users needing genuine 28-core throughput on Intel's platform specifically.
Platform
This workstation chip requires a specialized LGA 3647 motherboard, typically paired with hexa-channel DDR4 memory for genuine workstation-scale bandwidth, a fundamentally different platform than mainstream desktop builds.
How Is the Xeon W-3175X in Terms of Performance
With 28 cores and 56 threads, this chip targets the most demanding workstation workloads: professional 3D rendering, video production, and scientific computing, competing directly with AMD's Threadripper lineup for extreme multi-threaded users specifically wanting Intel's platform.
Benchmarks
Cinebench R23 multi-core scores of 31,119 place this chip at genuine workstation-tier throughput. Geekbench 5 multi-core scores of 23,453 confirm massive parallel capability, though single-core scores (1,112 Cinebench R23) trail more modern architectures given this chip's Skylake-based design.
