How to Choose a Processor for Your Industrial Embedded PC

Industrial CPU Tiers: From Low Power to High Performance

CPU Class	TDP	Best For
Intel Atom / Celeron N	4–15W	IoT gateways, data loggers, simple HMI
Intel Core i3 / i5 (U-series)	15–28W	SCADA workstations, operator panels, MES terminals
Intel Core i5 / i7 (H-series)	45–65W	Machine vision, SCADA servers, AI edge inference
Intel Core Ultra / Xeon	55–125W	High-performance edge computing, multi-camera vision, AI NPU
AMD Ryzen Embedded	15–35W	High-graphics, multi-display applications

Key Processor Considerations for Industrial Embedded PCs

• TDP vs fanless cooling — fanless chassis have a heat dissipation limit (typically 15–65W); never exceed the chassis TDP rating
• Industrial temperature grade — not all Intel Core processors have industrial temperature variants; confirm extended-temp support with your hardware vendor
• Long-term availability — industrial embedded processors have 7–10 year supply guarantees vs 2–3 years for consumer CPUs
• Integrated graphics vs discrete GPU — for basic SCADA displays, integrated graphics is sufficient; for machine vision or AI, a discrete GPU may be required

Matching CPU to Application

• Simple data logger / IoT gateway → Intel Atom or Celeron N, 6–15W fanless
• SCADA workstation (1–2 screens) → Core i5 U-series, 15–28W fanless
• Machine vision (single camera) → Core i5 or i7 H-series, 45W fanless or active cooling
• Edge AI (NPU + vision) → Intel Core Ultra with integrated NPU or Core i7 + NVIDIA GPU
