Is there any differences (Shaders/ROPs or anything else) between these two models ?

I own a 7970 @ 1275/1700 1.2v (Accelero 7970), just wondering if both clocked at the same speed will perform the same.

-------------------------

Gigabyte G1.Sniper 3 | 2700K @ 4.60Ghz 1.26v HT ON [IX TIM] | D14 3 x GT 1450RPM | 2x4GB G.Skill Sniper 1.25v | HD7970 @ 1275/1700 Accelero 7970 | 2x1TB Samsung SP F3 + 1xCorsair F3 GT 180GB | CM HAF-X | M12 II 750W

No, the only difference is in the clock speed.
GHz editions, as the name implies, are clocked at 1000 MHz
or higher.

[Corsair 16 GB CL9 DDR3 @ 1333 MHz] [WD 600 GB VelociRaptor HDD] [Seasonic Platinum Series 1000 PSU]
[Creative Sound Blaster X-Fi Titanium HD] [Asus HD7970 DC2 @ 925 / 1375 MHz]
[Samsung S24A650D on DisplayPort @ 1920 x 1080p / 60 Hz]

.. And can also turbo up to 1050mhz. Your card outperforms a stock 7970 GHz edition.

with a little help with  msi after burner a stock/default clock speed card can reach  a  very high overclock   ,  but just like cpu overclocking your milage will varry

Still overpriced compared to nVidia IMO, it should be $399.99 for the base stock card, ~$425 for the stock overclocked card, and ~$450 for the OEM aftermarket cooled cards, then maybe another $25 price hike for the Ghz edition

Looks to be priced right to me. With the 12.7 beta's at least. Pretty huge win if toms is right. It'll mean in the first time in 4 or 5 generations of GPU's AMD has a flagship thats faster then Nvidia X80 Version of what they are using.

yeah  it's true  the   beta 12.7's  made a large differance  in alot of games  even more then the reviews state

and the differance between  normal 7970's and the new ghz edition  , is the firmware   , and maybe they are binned higher

Doesn't matter if the performance is upped to GTX x80 levels, the power draw is still greater than the nVidia counterpart. I also don't like how they killed throttling (though this is quite likely a feature temporarily removed in the latest beta drivers so they can make sure it will work right with the Ghz edition cards without issues). Idle power draw is nice, but it still slurps down 30w more power than the GTX 680, which is hardly acceptable, though it may be explained by a new architecture having several inefficiencies to be fixed with the HD 8000 series, after all the fun that was poked at Fermi, I'm surprised nVidia didn't counter back with that clip from National Lampoons Christmas Vacation where he flicks on all his lights and they have to kick in the auxiliary nuclear generator...

it's only a extra 30 watts    lol    power consumption  is the last thing i think about ,  but i suppose some people care

For desktop chips it's not really an issue other than it makes AMD look bad, but the mobile market where every watt counts...
