It was a tough afternoon for the Millers, who were brought back down to earth with a bump after wins over Northampton Town and Exeter City.
Cardiff played with 10 men for the bulk of the game after Ryan Wintle was dismissed, yet still looked incredibly comfortable.
Goals from Omari Kellyman, Chris Willock and Isaak Davies put Rotherham to the sword and the hosts were perhaps fortunate it was not an even heavier defeat.
