> I don’t know of any x86 processors that can compete with the Arm processors that are in use, on power consumption to performance ratio Not anymore, but there was a time when x86 was (barely) able to compete in that area and there were some x86-based smartphones and tablets. But it was too little too late: x86 already was a niche. Developers absolute had to support ARM, but x86 was optional, so many apps were not available for x86, and that was pretty much it for those devices.
