Specialized Performance
AI / ML
- 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
- AMX and AVX‑512 provide strong CPU‑side matrix and inference acceleration.
- No dedicated NPU; AI workloads rely on CPU + GPU combination.
- Excellent for AI development and small‑scale training where multi‑GPU and large memory matter more than pure CPU TOPS.
Content Creation
Gaming
- 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
- Strong single‑core turbo up to 4.8 GHz benefits high‑FPS gaming.
- Lack of hybrid E‑cores avoids scheduling oddities compared to client CPUs.
- Cost and power make it hard to recommend over gaming‑focused desktop CPUs.
- Best paired with high‑end GPU for GPU‑bound titles where CPU overhead matters.

Our Verdict on Each
A 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.
Read the full reviewA heavyweight workstation CPU with excellent multi-threaded throughput and massive I/O, best suited for users who actually need 28 cores and 112 PCIe 5.0 lanes, not for mainstream gaming or office builds.
Best for: Building a single‑socket workstation that must support multiple high‑end GPUs, large DDR5 ECC memory, and many PCIe 5.0 devices for rendering, simulation, or AI development.
