The winger has held talks with all three clubs and has now decided upon a move to Emirates Stadium, having flown out to Switzerland to meet Gunners boss Arsene Wenger.
A statement on Cardiff's official website read: "Cardiff City were informed on Friday morning that Aaron Ramsey's preferred destination this summer is at the Emirates Stadium with Arsenal.
"We will now continue the dialogue with the Gunners with a view to Aaron's move being completed.
"The move unlike other options however does not include a loan back period at Ninian Park for the 2008/09 season."
