I didn't think 6970s could hit 395 MH/s out of the box, unless they (Tomshardware) did some tweaking to theirs just to make it benchmark slightly above a 5870.

Total BS in that article. Most of my 5870s can EASILY get a maximum of 440 Mhash/s when slightly overclocked to 960 MHz.

6XXX sucks compared to 5XXX. Even a 6990 sucks compared to the 5970 king ATM. A 6970 can almost never beat a 5870.

Nobody really knows how the 7XXX will perform or behave until some months after release to allow for optimizations and OCing.

Wow, 6970s get nearly 400 MH/s straight out of the box?

Uh,420 m/h with 11.6 drivers & 930/1375 OC on GUIminer/win7...but consumes 375 watts.In crossfire 840 m/h uses 740 watts.Not using MSI AB.

Temps are 72c @ 90% fan speed(very noisey).

Stock got me 360 m/h.

BTW,while gaming @ the OC'ed clocks,I use 440 watts in crossfire(BF3),big diff compared to all out mining Wink

I don't think they OC'ed the 7970 at all,so with some tweaking you might see 450-475 m/hash,just guessing though.As long as power consumption drops,it might not be too bad,BUT @ $500+,not a good bang for the buck Sad

930/1375 OC != "straight out of the box".

Are the 76xx's going to be a die shrink of the 6xxx's or still on the 40nm? If they're a die shrink they still might be worthwhile, current 66xx's can do 100mhsh/s

They almost certainly will be a die shrink. Once 28nm gets established there cost per transistor is lower. Not sure if even a double the 66xx would be worth it. 100MH/s even doubled is just 200MH/s per GPU? You got FPGAs that can pull that. Granted some people might be interested but density is going to suck if the "best" miner is ~200MH/s.

If this holds up, then SI looks like a bust for mining. All GCN and pricey. For example, the 7850 has less cores than 6950 and cost about the same. From the comparison of 6970 with 7970, it looks like GCN cores don't mine as well either.

So roughly 5% faster. Given it is a die shrink one would expect a shrunk and doubled 6970 to be 70% to 80% faster. CGN uses fewer more complex shaders and just like NVidia that results in lackluster mining performance.

Nothing to see here; move along. But I'm glad to see a commercial site like Tom's review the card for bitcoin mining. The 5870 is still the card to beat. At least until the 78xx series is released; those should be just as quick for mining and use 1/2 the power.

Maybe not. The early reports/leaks indicated that 78xx would use VLIW5 and if they did I agree a 78xx is a no brainer better mining card. The bad news is later reports have now indicated that 7800 and 7700 series cards will also be CGN. Only the OEM low end junk 7600 series will be a die shrink of 6000 series. If so then there likely will be no "good" new mining card.

Hmm, I wasn't aware of that latest news tidbit ... I was operating under the assumption that the 78xx would be VLIW5. If they are GCN as you suggest (Graphics Core Next), like the 79xx, then 2012 will not likely see better GPUs than the 58xx/59xx or 69xx. Sad

Sad

Yeah I am not sure what to think some sites are indicating GCN some VLIW5 and AMD hasn't confirmed one way or the other. The 7800s are suppose to launch sometime in late Feb so likely we will know more as it gets closer to launch date.

The 7970 shouldn't even be considered for mining; GCN is AMD's version of Fermi. It is marginally faster than a 5870, sure. But it uses 30% more power to achieve 10% faster performance (250W for a 7970 vs 190W for a 5870). Not to mention a 7970 will retail for $500, compared to $200-$250 for 5870.

We have to face it : Bitcoin / integer / bruteforcing is still a tiny share of the market ATM.

May be a tiny share, but we ARE on the radar. We have the 5th bullet on the main overview page.

Fold and mine faster than ever with AMD App Acceleration powered by the unprecedented 28nm GCN Architecture.7

Mining faster than ever? I like the way that sounds!!!!

1% faster than 6990 would be "faster than ever".

That is fuggin insane that AMD even mentions mining.... Maybe we could just freakin ask them if CGN or other new 7x tech will mine better than 5x/6x and if they have more data to share on it.......?? Someone? ;p

Wow, the fact that they speak about mining on their website is a great thing

WCG is cpu-only so far.

And Folding well... check the statistics now, ATI contribute most to their computing power, then nvidia then cpu. Ok i know, this is only because a tons of bitcoin miners started folding, and 1 nvidia still kickass tons of ati on folding
But maybe with GCN things will change

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.

Pffft, bullshit.

Try projects like Milkyway@Home (that's a DOUBLE PRECISION one), Collatz Conjecture or Moo! Wrapper. Nvidia sucks there.

Yes but what is the difference between those examples / Bitcoin and something like Folding@Home or WCG ?

The marketshare. F@H and WCG etc. are big while those examples and Bitcoin is relatively small in terms of penetration.
