Topic: AMD R9 290X? - page 21. (Read 108823 times)
i think the thing to do for ALTCOIN mining would be to pick up the old cards being discontinued. or just leave the network as is
Guys,
everything is rebrand exept the R9 290X
HD7970 = 280X
HD7850 = 270X
HD7770 = 260X
The 260X is similar to a 7790 iirc, but with "true audio". It's not a rebranding. 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.
The 290 series have 512 bit bus and the 290X has 2816 stream processors. So, we'll be looking at 1Mh/s Simple math tells us that the 290X should have around 20% better results than a 7970.

That's what I thought, 1mh/s for 250w sounds good to me. But too expensive at launch...650usd, yikes.

looks more like a 7950 to me 
do you mind sharing from what store you bought them from, the ones im usually buying from dont have them yet...damn it

stefffe, any chance that you could measure the power it draws with a kill-a-watt?
I got that thing in a closet somewhere, Im feeling too lazy right now

No extra options tho
Not surprising really, the 280X is just a 7970 with no voltage control
Dont know about the voltage control, I was able to lower it with 20% in CCC?

There must be valid driver on CD that come with card.
You need the 13.11 beta drivers from the AMD website.
Hi guys, just installed the card, its a gigabyte R9 280X 3GB OC. Cant seem to get the drivers installed tho, never had this problem b4. It gets installed as "standard vga adapter". GOnna try some stuff, brb.
I paid $350 for it, and Im from sweden so I guess its cheaper in the us

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?

Just got my R9 280X, gonna install it in 1-2 hours. Ill post hashrate if someone is interested...
Please do, and also the watt from wall and your undervolted settings

I am very much interested 
Also upload GPU-Z screenshot
BTW how much the card cost you?

Yeah but its gonna run WarFace like i stole it
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 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$/€ card then on one 650$.
I was told 290/290x is more energy efficiency, so it might be worth while in the long run.
