The Florida Today article On second flight, SpaceX Falcon 9 rocket to launch 'brute' of a satellite from Cape describes the upcoming SpaceX launch of SES-12.
At roughly 12,000 pounds, the SES-12 spacecraft built in France by Airbus Defense and Space is not the heaviest of its kind, but is big and tall.
“It’s basically two satellites in one,” said Halliwell, describing broadcasting and broadband satellites “smashed together into one bus.” (emphasis added)
According to Airbus, the satellite is the biggest and most powerful yet to rely entirely on electric propulsion to reach and hold its final orbit high over the equator.
Using electric propulsion cuts the weight usually reserved for chemical fuels, making mass more available for mission-related payloads.

Is this just vague marketingspeak, or is the number of transponders, or total bandwidth roughly double previous similar communications satellites? Are there two identifiably distinct satellite functions present using one bus? It certainly looks complicated:
