Guys, everything is rebrand exept the R9 290X HD7970 = 280X HD7850 = 270X HD7770 = 260X
So, The R9 290 boasts 2,560 stream processors, the current top model, HD7970 has 2048.
Simple math tells us that the 290X should have around 20% better results than a 7970.
So lets say a HD7970 gets to 750Kh/s, a R9 290X should get around 900Kh/s. Simple math, and then there is overclocking, a HD7970 that runs 750Kh/s is obviously OC'd pretty hard, so I am only just picking easy numbers on that one.
Your math is wrong. All things being equal (they won't be) 750Kh/s would extrapolate to 1031Kh/s for the 290X (37.5% more shaders) and 937Kh/s for the 290 (25% more shaders.)

Are you sure that the following is just rebranding? HD7970 = 280X HD7850 = 270X HD7770 = 260X Last I heard they are going to improve the performance instead of just rebranding. Thanks

Thanks Well, i've seen reviews but that is just upping the core 50 Mhz and you get 1 FPS more... And the 270X has 1280 cores, so the hd7850 core has been improved but not by much. (I think a hd7870 has 1280 btw).

that's even more expansive then a 7990. Need to know which is more energy efficiency ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

I think 7990 will be better in terms of speed , they work 1400khash+ dont they? For 650€ wich is supposed to be the cost of 290x you can get 3x 7950 and get 1800khash+ out of it. I doubt 290x will be able to top that.
The 280x might be best/most optimal mining card in terms of €/khash if they come out at 200€ and have the same speed as 7970.

I'm on same page here with you. No way 290/290X is worth that money, 3 x 7950 and when you sell you lose much less on three 200$/€ card then on one 650$.

Same 28nm production process, chip is bigger than 7900 series. Not sure it can be more energy efficient. The only question is what GCN2.0 brings.

I'm also interested to see is it acting completely same as 7970 or is it better.
What brand you got and is voltage unlocked?

You need the 13.11 beta drivers from the AMD website.
