The XFX card is clocked exactly the same as the ATI reference card with a 750MHz core clock and an 800MHz memory clock. As such, performance with the card should be nearly the same as the other HD 4770 reference clocked cards. ATI has released Catalyst 9.5 drivers to support the new card and performance is in line with the other cards.
