With the 28nm core I expect we will be able to overclock higher and run them cooler which should yield better results.

Well there is no guarantee.  AMD may be pushing these cards harder than 40nm models.  Remember 40nm is pretty mature now so getting yields high is almost trivial which means you have lots of very good chips (more than you can use in the best cards).  Sometimes after a die shrink overclocking hits a brickwall until they work the kinks out. 

I remember one Intel CPU after a dieshrink that couldn't be overclocked more than 2% without crashing.  Intel was selling the chip at almost redline because they didn't have good enough yields to use a better quality chip for that part/pricepoint.

Like the rest of you, I'm waiting impatiently for someone to get some hashing numbers.  Exciting stuff, though!  Why not release it last week so sell them for xmas?  If I was in charge of this world, that's what I would have done.

AMD wanted to have it in stores 2 weeks ago.  The chips are made by TMSC and they had delays.  Nothing AMD could do but watch and see Christmas shopping season vanish.

That is quite impressive, though I doubt the ~2x speed boost will entirely translate to mining. Many of the benchmarks from the review showed more like a 50% increase, anyways. Cost-wise, at a MSRP of $550, so $450-$500 at Newegg, it still would not be as good a deal as older cards in MH/s per dollar. Electricity costs could be cut, certainly, but if electricity is your main hindrance to profitability, FPGAs will still be way more efficient in MH/s per joule.

Not sure why he included that chart.  It is FLOATING point performance.  It has nothing to do with Bitcoin mining.

I wouldn't call it "ATI = fail yet again".

The 5000 & 6000 series cards are based on a concept of LOTS of simple shaders.  The issue is that a 7000 cards based on the same architecture would likely have way MORE but relatively inefficient shaders than a mainstream video game can use.  Pixel count isn't rising as fast as it was in the past.  The number of effects isn't rising either but gamers are expecting more complex and immersive effects.  The more to more complex shaders was inevitable.  If it wasn't the 7000 series it would be the 8000 or 9000 series.  

It just is bad news for miners as SHA-256 is pretty damn simple.  It only takes in the hundred millionth of a second range to complete a hash.  Other than Bitcoin nothing needs that much hashing power.  Other integer performance seems to be doing fine.  NQueen is a classic non-cryptograpy integer based problem and the 7970 is roughly 2x as powerful as 5970.     AES even got a nice boost, it will be nice to use GPGPU to open encrypted files 20x faster.  

AMD never intended for Bitcoin to be fast with their videocards.  It was more like a very lucky coincidence we got as good of performance as we did.  Now the trend is towards more powerful shaders and that is likely going to break that beneficial happenstance. 

Makes me glad I am sitting on 16 5970s though.  


On edit:  I wonder how much L1 cache the GPU have.  Would be beyond funny if these cards did great a so called "GPU unfriendly chains".

Got a nice stock of 5870s. Happy right now. ATI = fail yet again.

IMHO they are still pretty damn smart and they want to compete with Nvidia. Nvidia blows ATI for things like weather forecasting, folding and other important scientific, real world changing stuff. The catch ? Bitcoin is integer and folding ( GPGPU computing in general ) is based on floating point and DP ( double precision ). The 58xx were EPIC for integer but crap at floating point. The CGN crap is bringing more FP to the table to compete with Nvidia. We have to face it : Bitcoin / integer / bruteforcing is still a tiny share of the market ATM.

Too soon to see mining performance, mining software still has to be optimized.

No way. Look @ efficiency.

HD7970: 414 Mh/s @ 254 W
HD5870: 375 Mh/s @ 190 W

Ah, excellent news. Cant wait to buy some cheap 58x0 cards from gamers upgrading to this.

malevolent -- Point taken, i just get carried away with banter sometimes Smiley Actually i dont give 2 shits about the 7 series no more haha.

BF3, i kick ya ass in heli. Was 89th in world before on BF2. I got BF3 after i promised not to buy EA again for £7.50. Paid 11.99 for expansion for been a BF2 sucker ha. Me and a good co pilot and you aint got a chance with the new systems.

FPGA for the win, whatever adios, see you next year

Well,we are always looking for good players to fill our server,check us out,we have our own 64 man server & a private server for us to practice on.Just come & kill,we're not stars at the game but we do have a great time,we also use Mumble for comms:)

http://theblackduck.net/araven/

Hope you get your game goin Mouse,would be fun to see some guys from the "Bitcoin place" in game Cheesy

We have some fixes we found out about on our forum,so check em out & hope one of em gets you up & playin!!!!!!!!!!!!!!!!!!

BTW,my name in game is my name here Cool

Well,MSI Afterburner crashes my PC when playin BF3 or BC2,so I'm stuck using CCC or whatever it is.So no underclocks for my mem...........& the 6970 xfire is soooo sweet Cool

As for CPU,I OC my FSB to 206,a little extra for the games Wink

But my gaming is more important than mining for now,unless we hit $8-10 per coin......or more Undecided

+ gameing is anger management for me Shocked

Thanks for the info Grin

After this last patch I noticed my frame rates dropping to like 1-2fps every now and then.  Usually it's around 80-120.  It happens often enough to be REALLY annoying, and sometimes the game will just lock up for me.  It usually occurs when I turn really fast or scope-in -- basically whenever I encounter an enemy player, lol perfect timing!

I did some searching and there's currently no fix for it, but some people have had success by updating their audio drivers (for those using Realtek onboard audio).  Also disabling CCC's "AMD Optimized" tesselation seems to help as well.  Unfortunately I've yet to find a fix that works on my system. Sad

Weird, i just hit "Reset" on MSI Afterburner before playing and everything run fine, BF3 too

Well,I get 840 m/hash(420 each with OC'in) with my crossfire 6970's @ 740 watts(entire PC with fans & AMD 965 quad).My electricity is .11 kwh=about $60-80 per month.Still profitable,but barely.

You could sell your 6970 and get a 5970+5850 (or 5830 at least)

You could also underclock and undervolt your CPU to 1 GHz or less... unless you ain't only mining with it Cheesy

I rock BF3 so I'm getting my moneies worth Grin

I'm watching & waiting..........the 7000's need to beat that by 30-40%(power consumption or hashing) for me to even think about upgrading.

Doubtful I'll upgrade my GPU's anyways as FPGA's are looking more promising,but @ almost $600 for 300+ m/hash its still a bit much too invest just yet,if they come down to around $400 or so..............
