iMX8 Product Families

The iMX8 series of applications processors are the next generation of multi-core platforms by NXP heavily oriented towards potentiating solutions for advanced graphics, imaging, machine vision, audio, voice, video, and in general infotainment and safety-critical applications.

As part of NXP's go-to-market plan, it is foreseen to launch 4 different product families: iMX8, iMX8M, iMX8M Mini, and iMX8X. The differences between each of the families can be summarized in the chart provided by NXP and shown below.

It is important to note that, provided to date, iMX8M is the only family that is being commercially distributed, the rest of the families remain in the PreProduction stage.
