Just asking if r9 380x is better then r9 280x/290.
It's a rebrand,but same hashrate and low power consuming.
The 380x in NOT a rebrand.
The 380 is a rebrand of the 285, which was a 'side-grade' compared to 280x but still slower than 290.
The 380x never existed before (it was produced for some OEM products only).
The chip is
Tonga (GCN1.2) and it is considerably different from previous vidcards.
FYI.
