Yeah, there's a lot of confusion and rumors around the new R line, and the fact that AMD still has not released any official details isn't helping.
The only new products in the R9 line are the 290 (Hawaii Pro) and 290X (Hawaii XT.) Everything else is just a re-brand. That's why the non-reference 280 and 280X are already on the market, because all OEMs had to do was print new boxes
I will probably post a buyer's guide on the forums once I am 100% sure on all the details. But for now, it pretty much breaks down like this:
R5 210 => HD 5450/6350/7350
R5 220 => HD 6450/7450
R5 230 => HD 7470
R7 240 => Crippled version of HD 8570
R7 250 => HD 8570
R7 260 => Re-worked HD 7770 with 128 more stream processors
R7 260X => HD 7790
R9 270 => Re-worked HD 7870
R9 270X => Re-worked HD 7870
R9 280 => HD 7970
R9 280X => HD 7970 Ghz Edition
R9 290 => Re-worked and underclocked HD 7970 with 512 more stream processors
R9 290X => Re-worked and underclocked HD 7970 with 768 more stream processors
