What is better? Sapphire r9 280x dual-x oc or and Radeon r9 380.
There is often a shift in the lineup when refreshed as AMD did, but this time, they are pretty much direct rebadges. 290X = 390X+oc, 290=390, 280X=380X and 285=380 and so on.
Thus, the 280X is more powerful as the 380 is a rebadged 285 which was a tweaked 280.
