i buyed a new gpu RX570 4 gb and when i placed it on my pc
and when i downloaded the drivers it's detected as an RX580 8 gb
whats the problem?
looks like you got 580 gaming x in a 570 box. are the serial numbers on a card and box matching? run some tests, if it scores like 580 then its 580. probably shop mistake
you're right it's an rx580 it's shop mistake
