COM Express Type 6 Buying Guide: Intel Core i3 vs i5 vs i7

→ COM / SOM→ COM Express→ Buying guide

COM Express Type 6 is the most widely deployed computer-on-module standard for x86 embedded systems. When you buy a Type 6 module, two decisions drive cost, performance and thermal design: the form factor (Compact or Basic) and the processor class (Intel Core i3, i5, i7, Xeon or AMD Ryzen Embedded). This guide helps you choose quickly and avoid over- or under-specifying your platform.

Step 1: Compact or Basic?

  • COM Express Type 6 Compact (95 × 95 mm): the default choice for fanless or space-constrained systems using 15–28 W processors.
  • COM Express Type 6 Basic (125 × 95 mm): more room for 35–45 W H-series CPUs, Xeon processors, two SODIMM sockets and better heat spreading.

Both share the same Type 6 pinout, so a well-designed carrier board can accept either size with the right mounting holes.

Step 2: Core i3, i5 or i7?

  • Intel Core i3: the lowest cost per unit. Ideal for HMIs, kiosks, gateways and controllers where a few cores and integrated graphics are enough.
  • Intel Core i5: the sweet spot for most industrial projects. More cores and Iris Xe graphics for 4K multi-display, machine vision and test equipment.
  • Intel Core i7: maximum Core performance for edge AI, image processing and video analytics.

A practical rule: size the CPU for your peak workload plus 30% headroom for software growth over the product lifetime. Upgrading later is possible thanks to the standard pinout, but requalification has a cost.

Step 3: Consider Xeon or AMD Ryzen Embedded

If your application needs ECC memory and server-class reliability (defence, avionics, medical imaging), look at the Type 6 Basic with Intel Xeon. For graphics-intensive designs such as gaming, signage or medical displays, AMD Ryzen Embedded modules offer strong Radeon graphics and long availability.

Step 4: Check temperature range and lifecycle

Industrial projects often require -40/+85 °C operation and 7 to 10+ years of availability. Not every SKU is available in industrial temperature, so confirm this before freezing your design. Tokhatec secures long-term supply through the OEM+ Program.
