I believe in industry parlance this is called an Advertorial (an advertisement dressed as an editorial). I didn't see a disclaimer though so either they are being dishonest with their audience or very tone deaf.

The NUC seems more like a Mac Mini than a real desktop PC and comparing it to a gaming PC is just strange. Despite their argument, yes, if you want to play games at optimal graphics and performance levels you DO still need a discrete GPU. Even game consoles (which require a fast data bus) have a discrete GPU despite their (usually) unified memory architecture.
