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](https://bitcointalk.org/Smileys/default/smiley.gif) ).

Guess we won't know for sure until someone gets a Kill-a-watt (hint hint OP ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ). 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](https://bitcointalk.org/Smileys/default/wink.gif) to buy HD79XX ![Cool](https://bitcointalk.org/Smileys/default/cool.gif)

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.

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](https://bitcointalk.org/Smileys/default/huh.gif)

Get some sleep dude and stay off SR !
