Looks like the 5970 has lost it's crown. I'd be surprised if that card pulled more than 200 watts.

Why & Why?

7970
650 MH/s
200W?
$549+

5970
750MH/s
250W
$300 (used)

Now the 7990 will likely dethrone the 5970.  I would guess (based on 7970 results) it may w/ some optimization be the first 1 GH/s card.

As for the wattage.  It is rated for 250W and other benchmarks have put it at 230W under full load.  While it might be less while mining (if mem is downclocked) what you make you think it would be 30W less while also overclocked 20%+?

Guess we won't know for sure until someone gets a Kill-a-watt (hint hint OP Smiley ).

I thought that because my numbers were wrong. I was thinking this card would pull about 200(because I thought it's TDP was 150) and it's over clocked. My own 5970 pull around 300 to get 750 mh.

Downloaded the sources for diablominer and compiled them. ~650MH/s with the default diablominer settings and the card OC'd @ 1125/975MHz:

~530MH/s at standard clocks:

WTF and thats with -v 1? 79xx could be glorious if I can find the right settings.

Edit: You know, I just noticed the op post said GPU threads had a viable increase beyond two. Huh. I should go see if that is worth abuse, I never got better performance beyond 2 on DM (its hardwired to 2, and was the first miner to abuse that trick).

The card has been tested under full load pulling 192 watt by a hardware review site who had their hands on the first cards
That full load was doing a heavy game for a certain amount of time, they also mentioned that if you overclock the card it will use more then 200 watt.
And including burnin with furmark now do not tell me you do not know how powerfull furmark is
Its actually more stressing cards then they will ever do in real time usage including mining

This site has allways been in this respect good they test every aspect, and i believe they did more testing then others
So there is no doubt about the results, these guys test with better equipment then a kill-a-watt

Onto the answer with the threads running in the old stucture the alu where not capable of doing more then 2 threads
the new GCN seems to make it possible to make better use of the alu's is stated by amd.
So somehow you can get the card to set every and all alu to work
Which was simply not possible on the vliw architecture
The big increase in numbers on the review (most games) shows clearly that this card easily does up to 33% better then the 6970
I think for the coders out their this card poses a real challenge to get more out of it then with previous cards.
Nevertheless we have to wait what prices it will get at, after the initial run on them because i already know many of the gamers i talked to want 1 or more of them as soon as they can

Curious. What intensity did you run it at on cgminer? I figure the 7970 will be the first GPU to benefit from -I 10. On your screenshot it was only intensity 7!

Mining pulls significantly more performance than games do, and only slightly below Furmark. ~250w with overclock sounds correct for mining.

If sommeone will pull out somme more mhash`s from GCN, it could be best choice.
The prize will cut it a bit untill NV will show its babby.
Theres always hope, that somme gamers will sell somme old and "crappy"HD58XX/5970 Wink to buy HD79XX Smiley Cool

Thanks for the tip. I just tried -I 10 but it does not seem to have a significant effect on the hashing rate when compared to -I 7.

You should try -I 8 and 9.  It should be about 5% better.

I just tried changing EXECUTION_TOTAL from 2 to 3 on my machine and the hashrate went up slightly from 662.8 MH/s to 666.0 MH/s.

impressive numbers, when the prices goes down $400 these cards should be hot

now this card is out.. how about some ++real++ benchmarks?
this thing has 500 more sp than the 6990 - how can it possibly be slower?Huh

LOL you don't know a thing about mining, do you ?

6990 has 3 072 or 2*1536

5970 has 2*1600 or 3200 shaders

7970 has 2048 shaders

5870 has 1600 shaders

7990 supposedly has 4096 shaders ?

thanks for repeating what i said.
7970 has 2048 SP
6990 has 1536 SP
thats 500 more. per core, whatever, its more, MORE. so why is the card putting out so much less? maybe if you put your effort into explaining a decent answer (such as 'because the miners need re-optimisation') instead of being a flabberfinger - we could have all benefited.

6990 is dual GPU so has total of 3072 shaders gets about 800 mhash/s using two cores total.
7970 is single GPU so has total of 2048 shaders get about 666 mhash/s using one core total.

Get some sleep dude and stay off SR !
