Can a Double D beat an FTW? 7970 once again challenges the 670

Not only is XFX's latest HD7970 a Gigahertz Edition it also bears their proprietary Double Dissipation cooler.  This not only provides efficient cooling but also gives the card top a very distinct look to go with the black PCB on the back.  The card runs at the stock speeds of a 7970 GHz edition, though with the help of AMD Overdrive [H]ard|OCP hit 1210MHz on the GPU and 6.86GHz on the memory.  In the end though that was not enough to win a recommendation from [H] as there is not much difference in the performance between this card and a customized GTX670 ... which happens to average $30 less in price.

"With continuous AMD price drops the XFX Double D HD 7970 GHz Edition video card has dropped into line with many of NVIDIA's GeForce GTX 670 cards. Find out if the XFX's Double Dissipation technology will excel this video cards overclocking potential when we put it head to head with GeForce GTX 680 and overclocked GeForce GTX 670."

They used the 12.9 beta drivers.

I'm having a tiny problem I can't seem to be able to subscribe your feed, I'm using google reader by the way.

"The card runs at the stock speeds of a 7970 GHz edition, though with the help of AMD Overdrive [H]ard|OCP hit 1280MHz on the GPU and 6.2GHz on the memory."

Yeah man, you have a reading problem!

The card that reachs 1280 MHz/6.2GHz itsn´t the 7970 GHz Edition, it´s the Gigabyte GTX 670, the GTX 670 used in the review. The 7970 GHz reachs 1210 MHz (GPU) and 6.860GHz (mem).

By the other side, this "Oced" GTX 670 is crap over crap, this is the first GTX 670 that I "see" with only reachs 6,2 GHz in the memory.

The two cards (GTX 670) that I have/had reach 6,85 GHz (poor result) and 7,4GHz (a good result) in the memory. The GPU OC in the GTX670 of HardOPC is "normal", far of excellent or good.

The GTX 670s are very sensitive to the memory OC, if you don´t make a good memory OC, the GPU OC is pointless and ineffective. And I repeat the point, I NEVER see, directly and indirectly (friends and acquaintances), a GTX 670 with "the HARDOPC memory OC", their and my cards reach a very much better memory Ocing.

About the use of Catalyst 12.9:

Well, they, in HardOCP, use forceware 306.02 BETA driver for the GTX 680 (very OLD driver) and forceware 306.97 WHQL for the GTX 670("official", but isn´t the latest driver too).

The last official AMD driver is the Catalyst 12.8. Well, if they are using a "beta" driver more recent that the nvidia drivers (a obsolete beta driver and the oficial driver, a worse situation, then, that the AMD setup with a more recent driver than its oficial driver).

The complains about the drivers aren´t only to one side.

Good catch, I totally transposed those numbers. 

You are getting some nice overclocks from those cards, are you pretty much leaving the GPU and just upping the RAM frequency?
