Rage3d has an excellent article.

The AMD Radeon HD 7970 doesn't introduce any new filtering methods but, like Cayman, does support EQAA, in addition to MLAA and the traditional standard & edge detect modes. Partially Resident Texture support can make for better hi-resolution images, as seen in AMD's Leo demo, made the by the creators of AMD's Toy Shop demo. Watching Leo at the AMD SI tech day was nothing short of jaw dropping. Sitting in the front row and watching a pre-rendered quality animation being real time rendered on three 60" HDTVs was an incredible experience. The demo uses tessellation and new indirect light methods processed by compute, as well as PRTs, to deliver a very high quality image. The Leo demo will be available sometime later, once the usual legal bumpf has been taken care of.

That's almost perfect 300% scaling! 😱

Doing the math that's 2.986!!!!

197.642 / 77.2 = 2.56 = 256% scaleing (out of a possible 300%) for 3 cards.

still room for improvment in drivers.... that said... doesnt look too bad avg. 200+ fps with everything on in BF3.

for the rumors about disabled cores

197.642 / 77.2 = 2.56 = 256% scaleing (out of a possible 300%) for 3 cards.

It's actually ~260%, assuming linear scaling with clocks from 925 to 1100/1125. He was using the wrong card (stock), but so are you (1125 MHz instead of 1100) 😉

 

[Arkadrel]

Crap your right.... I just assumed 1125mhz was used for both..
but he used only 1100mhz for that result of 197.6 fps.

3x 7970 @1100mhz = ~200 fps avg in BF3 1920x1200 everything on.

260% out of 300%.... still room for improvements hehhehe 🙂

 

[Panopticon]

not to thread hijack but based off previous AMD launches should we expect this card to sell out day one despite reports of healthy supply? Also based off of passed launches such as the 58xx how long after initial sellout did a second round of cards become available? This is the first time I have bought into a new gen at launch so i'm trying to assure that I can snag a 7970 or 50 at time of launch.

edit: I didn't mean to post this in the official review thread. Mods feel free to delete I don't want to derail a benchmark thread.

I'd like to see that 7970CF compared to my 6990+2x6950 setup, but it would probably take 7970TriFire for me to see any gains, besides quadfire has much less microstutter than either 2-way or 3-way setup.

 

[Arkadrel]

@Lepton87

7970 in CF and both overclocked would be faster, than your 3x6950 setup.
Hell a single 7970 overclocked enough (~1200mhz+) beats a 6990/590 on its own.

 

[Lepton87]

I don't have 3x6950, I have 1x6990+2x6950. Not every sample overclocks well, for example guru 3d only managed 1050/5800, I can overclock my cards by a similar amount.

Guru 3d managed 1050/5800 in their original review because that's where they stopped. In their follow up they got 1125 on the core of the same card. They stopped because they wanted to make sure they finished their review without frying the card.

I still wouldn't count on every sample reaching power tune limits, techpowerup got 1075MHz/1715. The memory frequency is just awesome though, although judging from their brief tests it doesn't seem to increase performance by any appreciable amount. It seems that 7970 is not memory bandwidth bound.

 

[badb0y]

Lol so it not only beats the performance of GTX 580 but the price too? Time to camp Newegg lol

AMD makes money and I'm sure it's still a very healthy amount, consumer gets a kick a card at a great price, AMD has made turned some hostile cheapskates like myself into potential customers.

Good business decision IMO.

Now we have to see if us consumers are passed the difference or it goes to the retailer pocket.

Whoops, my fault, I realized I used the non-OC number for my base. Haha.
