Specialized Performance
AI / ML
- Intel AMX provides dedicated matrix acceleration for deep learning workloads.
- Suitable for small to medium models and inference tasks; large-scale training still typically uses GPUs or specialized accelerators.
- No integrated GPU or dedicated AI accelerator beyond CPU-based AMX/DL Boost.
- AMX provides dedicated INT8/BF16 acceleration for quantized inference and some AI workloads
- AVX-512 and DL Boost further accelerate traditional ML and HPC codes
- For large-scale training, high core count EPYC or Threadripper PRO often outperform; Xeon W shines in AMX-optimized inference and mixed workloads
Content Creation
Gaming
- Single-thread performance is strong thanks to 4.8 GHz turbo.
- Most games cannot leverage 22 cores; GPU and platform matter more.
- Not a gaming-focused SKU; high cost and power are hard to justify for pure gaming builds.
- 4.8 GHz max turbo gives solid single-thread performance for many games
- Lack of hybrid architecture and gaming-specific optimizations means newer desktop CPUs often lead in 1080p high-refresh gaming
- Best used for gaming plus heavy background workloads, not pure gaming builds

Server-oriented alternative with more memory channels and higher memory bandwidth if you’re building rackmount AI or HPC nodes rather than deskside workstations.
Our Verdict on Each
A very capable single-socket workstation CPU with high core count, strong I/O, and AMX-based AI acceleration, but its high power and cost make sense only for professionals who can fully utilize its parallelism and PCIe bandwidth.
Best for: Professional workstations for 3D rendering, CAD/CAE, video editing and AI development where you need many cores, lots of PCIe 5.0 lanes, and ECC memory in a single-socket platform.
Read the full reviewA robust single-socket workstation CPU with excellent PCIe 5.0 expansion, strong multi-threaded throughput, and AMX-based AI acceleration, but high power draw and tough competition from AMD Threadripper PRO on raw core count and memory bandwidth.
Best for: Single-socket workstation for CAD/EDA, simulation, or AI development where you want AMX, 112 PCIe 5.0 lanes, and 8-channel DDR5 ECC, and are already investing in a W790-based OEM or validated system.
