Sommaire

Industrial CPU Tiers: From Low Power to High Performance

CPU Class	TDP	Best For
Intel Atom / Celeron N	4 à 15W	IoT gateways, data loggers, simple HMI
Intel Core i3 / i5 (U-series)	15 à 28W	SCADA workstations, operator panels, MES terminals
Intel Core i5 / i7 (H-series)	45 à 65W	Machine vision, SCADA servers, AI edge inference
Intel Core Ultra / Xeon	55 à 125W	High-performance edge computing, multi-camera vision, AI NPU
AMD Ryzen Embedded	15 à 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 à 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 à 10 year supply guarantees vs 2 à 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 à 15W fanless
SCADA workstation (1 à 2 screens) → Core i5 U-series, 15 à 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

For reliable fanless operation in ambient temperatures up to 50°C, specify processors with TDP of 15W or less (Intel Atom, Celeron N-series, Core i-series low-power variants). For ambient temperatures up to 40°C, 25 à 35W TDP processors (Core i5/i7 embedded U/H-series) are reliably cooled in well-designed fanless enclosures. Processors above 45W TDP generally require active cooling.

Intel Atom processors (x6000E Elkhart Lake series, 6 à 12W TDP) are designed for IoT gateway, edge connectivity, and protocol conversion applications, high I/O integration, low cost, lower performance. Intel Core i5/i7 (25 à 45W embedded-grade) delivers workstation-class performance for SCADA, machine vision, and AI inference. Choose Atom/Celeron for simple data collection; choose Core i5/i7 for demanding real-time processing.

SCADA client and HMI applications typically run well with 4 à 8GB RAM. SCADA servers with large tag databases need 8 à 16GB. Machine vision systems running deep learning models benefit from 16 à 32GB. IoT gateway and protocol converter applications function reliably with 4GB. As a rule, specify more RAM than your application currently requires, it is the cheapest upgrade that prevents future performance bottlenecks.

Industrial embedded PCs should use NVMe SSD (M.2 or 2.5-inch) rather than spinning hard drives. SSDs have no moving parts (critical for vibration resistance), faster boot and application load times, and operate across the full industrial temperature range. Choose industrial-grade SSDs (with power-loss protection and wide temperature ratings) rather than consumer SSDs for production applications.
