Stop linking 280x cards in a 290x thread. Link 290x cards or gtfo

290X have new architecture designed toward gaming performance.
For mining old cards and old cards with new name are still way to go.

Got mine Sapphire Vapour-x 280x today, works 760khash without too much hassle. 1080/1500 1,13v @ 68 C, fan 68%. Also VRM is at 88 C and 84 C wich i like, the 7970 could easily go above 100 C.

I really like the back plate on the GPU, dont know if 7970 vapour-x also had one tho.







Thanks for the update, but you missed one important information, what's the power consumption.

Keep in mind, Toms is doing no O/C, no option flags, it's basically out of the box with guiminer. My guess is that a fully tweaked setup would be in the 950 KH/s range for scrypt. Still, lower than I anticipated. 2x$200 7950s are a better deal.

Well it all comes down to power consumption though.
2x7950 draws more than 1x290X.

Question is how much?
2x7950 should be around 400W right? And according to tom's hardware 290x draws 300W -and not even o.c.-ed as heavily as a miner's GPU would Cheesy So probably about 330-350? It would take quite a while before those 50W power cost would even itself out.

I dont use cgminer on this desktop PC wich i have 280x currently in. Here is the pic of my guiminer scrypt that i use here: These are the settings that give me those khash rates.



I get 525 khash with those settings Sad
And this settings ? 1080/1500 1,13v @ 68 C.

And make sure you set gpu threads to 2, i get about 525khash with 1 gpu thread.

Guys, R9 290X was available for order today. Will cgminer work right out of the box for this card or do we need an updated OpenCL code for it to work? Thanks

Can you please show your config file for that khash?

I get 600 maximum with my 280X... I could get 700+ but cgminer reporting a huge amount of HW errors

Seeing that makes me think it might do 800 or more in scrypt...512bit bus, 6.4ghz mem when oced.

800 seems really low for the price, need at least 1000 to worth the price right?

For the same price you can get 7990 and 1300khash+.

I think those are non-oc tests. But still it shows the value compared to the old cards. So im thinking if my 7970 works 760, and 290x works 70 more compared to 7970 based on that chart, we should be getting about 840-850khash on this?

Looks shitty to me, you get 2x 280x for about the price of one 290x and you get ~1500khash vs. 850khash for the same $$.

Doesnt look that impressive to me, i'd like to see some scrypt tests tho. And it needs ~ 300W at full load.

Based on this chart, its not worth it.... hopefully someone would get it by today or tomorrow and we can compare Smiley

I don't think this is accurate but anybody that bought R9-290x can confirm this?
