Ole Gunnar Solskjaer's side slumped to the foot of Premier League table with the defeat, with a difficult trip to Manchester United next to come after an FA Cup outing to Bolton.
But Noone, who scored to make it 2-1 and was a real threat throughout the game, believes Solskjaer's side can take heart from scoring two goals at the Etihad Stadium - with Arsenal only the other team to do this in the Premier League this term.
The 26-year-old former Plymouth and Brighton player said in the Daily Mirror: "It was amazing to get my first Premier League goal for Cardiff here.
"To come through the leagues, then do this is a great feeling. I was pleased with how I did. I'm pleased to get the goal, but obviously disappointed we've lost the game.
"We're bottom, but we have to try and take the positives from the way we've performed here.
"Coming to the Etihad and scoring twice is difficult.
"We scored two goals and made it hard for them to break us down."
