GTX680 is beaten by HD 7970 in double precision floating-point

Hmmm....very interesting

The GK104, being a gaming card, has DP limited to 1/16 SP performance, so how is this news?

There are also many other architectural choices that make it not so great for compute, that would take up place and do very little for gaming performance.

Yes, there will be a GK110(2) later, possibly this year, to take care of compute.

Linking to the inq? Isn't that grounds for a paddlin?

What's interesting is if AMD chooses to launch the next-gen highend single gpu card with a Pitcairn level DP rate and retaining Tahiti for the low-volume compute market.

If AMD had any business sense what so ever, they'd already have a 1.2Ghz 7970 ready to go, and they'd release it next month with the new drivers. Have the review guide suggest using the new AA method, and then watch as GK104 gets pounded.

Unfortunately, they're not going to do anything like that at all. Had they released 7970 at 1050mhz, it would have been close to the benchmarks in Tom's leaked slides. These next few days are going to be a lesson to AMD about underclocking your card to make a TDP target that your competition lies about.

Nah, 7990 will crush the competition anyway - so why get into a hurry?

The leaked GTX 680 benchmarks are pretty much proven to be review guide copies - so regular reviews will probably show a way more even picture.

The INQ wrote that GTX 680 is beaten by HD 7870 in DPFP, btw.

HD 7970 stomps it into the ground by a factor of nine in that respect ...

MSI Lightning 7970 is being released at 1070 MHz stock clock.

They have successfully overclocked it to 1800 MHz:

The problem with Tom's slides is that part of Tahiti's performance evaporated since launch:

No amount of mhz will help if your performance magically disappears...

Yes, we are in a thread about that, btw.

And the guy tested the card with wrong drives, giving him 705 mhz, not 1006mhz stock, so you can add 43% to the score. Which will take the result above a 7870, but is completely pointless, see post #2. Rubbish article, suits the inquirer I guess.

Agreed. In true AMD fashion they are sitting around with their thumbs up their arses thinking it will all get better with the 7990 release in 3 weeks time.

People are getting tired of dual-gpu cards same as they get tired of PhysX and all the other bull. It's not good enough from AMD, they have been completely outmanoeuvred by Nvidia since the 560 Ti - which wasn't all that great yet somehow was accepted as "The hero of our times" by most review sites.

I feel that AMD just doesn't know how to market their stuff properly. They make great products, mostly, but their marketing dept. is really letting the company down, IMO.
