Buyers should pay attention to what Radeon RX 560 cards they are purchasing, as AMD was discovered to allow OEMs like Sapphire, Asus and PowerColor market RX 560 versions with 14 compute units instead of 16. These downgraded versions are most likely to be found on Amazon and Newegg.

Few, just checked my device and it still has 16 compute units.
How do you check how many CUs you have?
My XFX 560 I just got a week ago shows 14. Huh.
