AI / ML
- Intel AMX with FP16/BF16/INT8 and VNNI accelerates inference and light training on CPU.
- Not a replacement for dedicated accelerators but strong for CPU‑only AI prototyping and edge inference.
- Performance relative to Threadripper PRO and older Xeon W parts still awaits independent benchmarks.
- Intel AMX and AVX‑512 provide meaningful speedups for supported AI and HPC kernels
- No dedicated NPU; AI acceleration is CPU‑only
- Best for development and inference on models that fit in CPU memory, not large‑scale training
Content Creation
Gaming
- No integrated graphics; requires discrete GPU.
- High core count and turbo frequencies are helpful, but not optimized for gaming specifically.
- Modern high‑refresh gaming is better served by client‑oriented CPUs.
- Strong 4K throughput with a high‑end GPU, but not class‑leading
- High power draw and heat output under sustained load
- Best suited where gaming is secondary to creator or engineering workloads

Strengths & Weaknesses
Pros
- 20 P‑cores / 40 threads for consistent multi‑threaded performance.
- 128 PCIe 5.0 lanes – among the highest I/O counts in a workstation CPU.
- 8‑channel DDR5‑6400 support with up to 4 TB capacity.
- Intel AMX with FP16/BF16/INT8 for AI inference and analytics.
- Unlocked multiplier for tuning in workstation and enthusiast builds.
- Modern platform (W890, LGA4710) with PCIe 5.0 and DDR5.
Cons
- No integrated graphics – requires discrete GPU.
- 210–252 W power envelope demands robust cooling and PSU.
- L2 and total cache sizes are not fully disclosed by Intel.
- New platform; early adopters face premium pricing and potentially immature firmware.
- Competing Threadripper PRO parts may offer better per‑core or memory bandwidth in some workloads.
Pros
- 26 high‑performance P‑cores and 52 threads for heavy multi‑threaded workloads
- 64 CPU PCIe 5.0 lanes for multi‑GPU, NVMe, and high‑speed networking
- Quad‑channel DDR5‑4800 with ECC and up to 2 TB capacity
- Unlocked multiplier for overclocking on X‑series W790 boards
- Strong AMX/AVX‑512 acceleration for AI and HPC software that supports it
- Mature workstation platform with vPro enterprise manageability
Cons
- Very high power draw (250 W base, up to 300 W turbo)
- Expensive CPU and platform compared to high‑core‑count desktop alternatives
- No integrated graphics; requires discrete GPU
- Less efficient than modern AMD Threadripper or desktop CPUs for many lightly‑threaded tasks
- Single‑socket only; no multi‑socket scalability

Our Verdict on Each
A strong mid‑range Granite Rapids-WS workstation CPU with excellent I/O and memory bandwidth, best suited for professionals who need serious multi‑threaded performance without stepping up to 30+ core SKUs.
Best for: Professional workstation builds where you need 20+ cores, 128 PCIe 5.0 lanes, and 8‑channel DDR5 but don’t require the highest‑core Granite Rapids SKUs.
Read the full reviewA powerful, expansion-rich workstation CPU with excellent multi-threaded throughput and platform features, but high power consumption and a price tag that only makes sense for professionals who actually need its capabilities.
Best for: Professional workstation build where you genuinely need 26+ cores, >128 GB RAM, and multiple PCIe devices, and can justify the platform cost and power draw.
