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.)

Don't get caught up in the game and have a nice day!

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

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).

Last time i've seen the branding there is no 290 non X, so I don't know what you are talking about Smiley

There is, I see some review it says that Radeon R9 290 is coming too, being that Radeon R9 290X even more powerful then R9 290.

Any news on launch price?


650€ for R9-290X and 520€ for R9-290. All other cards are rebrand with new price and little higher default clocks.

that's even more expansive then a 7990. Need to know which is more energy efficiency  Grin

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.

R9-290 sounds like a good idea...

Euro prices translate 1:1 to USD bro, so expect a $520 price at launch. Maybe lower after a month or so.

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$/€ card then on one 650$.

I was told 290/290x is more energy efficiency, so it might be worth while in the long run.

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.

You need the 13.11 beta drivers from the AMD website.
