The gargantuan Australian import turned the coveted Group One into a procession under trainer Aidan O'Brien's son, Joseph.
So You Think will not be seen again in competitive action in Ireland as he is due to take up studies in Australia later in the year.
He will, however, still be aimed at Royal Ascot next month before heading to Sandown to defend his crown in the Coral-Eclipse in July.
"He has an unbelievable presence," Aidan O'Brien said.
"We're probably only really getting to know him and doing the right thing with him.
"This is the last time you'll see him in this country.
"Training him has been an unbelievable experience.
"We'll look at Royal Ascot (Queen Anne Stakes or the Prince of Wales's Stakes).
"Then he'll go for the Eclipse (Sandown) as that's the only race that fits into his program before he goes into quarantine (for stud duties in Australia)."
So You Think registered his first Group One victory in Europe in this mile-and-a-half (2400m) prize 12 months ago.
While he went on to land the Eclipse, he returned to Ireland this weekend having suffered four consecutive defeats.
Although a slightly disappointing fourth in the Dubai World Cup on his first start of 2012, Ballydoyle's six-year-old was the 2-11 favourite for this lesser event and the result was never in any doubt.
Joseph O'Brien eased him alongside pacemaker Robin Hood rounding the home turn and soon stamped his authority on the race.
Famous Name was predictably the horse to give chase, but his long wait for a Group One will have to go on as he was not in the same league as So You Think, who eased home by six lengths.
"He's an amazing horse," the trainer said.
"He's very unusual in that his mane and his tail grow twice as quick as any other horse which means he has a wild look about him."
