"some lightweight graphical workloads and casual gaming is surely possible"
I understand this is just a marketing article for affiliate money but you clearly have no idea what you're talking about.
The 780m is roughly the equivalent to a desktop 1650ti. My mini pc with this chip set can run almost any game at 1080p 60fps. It can run emulation upto PS2 era at 2k upscaled at 60fps. For PS3 it can play most at full speed at 720p, more a limitation on the emulator than the hardware.
Again I understand it's just marketing slop but please let someone who actually knows/understands/owns/tested the hardware to write it.
