Why r9 280x don't support freesync. Their gpus are the as same as r9 300
I want to buy r9 280x,His performance is much better than 380,But it does not support freesync.why?
Because the 280X is a rebranded 7970, whereas the R9 380 is a rebranded R9 285. Freesync was not made available until Hawaii (290 series), Tonga (285), and subsequent cards.
