Ok thanks.
New info about the GHz version. I noticed the results from this review
OC results
Edit:
Investigation regarding lower performance then standard 7970.
Power Consumption
Not sure how accurate those results are.

Let say without knowing if this is due to a particular model.. basically for do 1075mhz( 1100mhz) i will not touch the voltage on my card, so 1112mv or 1175mv depending the card... their card is at 1256mv who is clearly too high... 1300mv is the max you can obtain from MSI Afterburner, 1256mv is something you will use for pass 1200-1250mhz, not for use at 1075mhz.
... Note, im not too much surprised if they will be some model who will throttle a little bit back ( 1075 to 1000mhz ), in 3Dmark11 ( the second test is extremely aggressive, this is where my oc break when i attain the limit of the card ( redsquare on the plant )

It doesn't make sense to me either. The GHz Edition shouldn't need to be at 1.256mv just to maintain 1075MHz clock rate. Which is why I posted about it. But if the rumor is true that we will see the GHz Edition later this week we will find out for ourselves what the real T2 versions are all about.
It's probably a better binned version that can sustain that much more voltage. It doesn't need it, but it might help with stability.
Which brings me to the conclusion that either they clonked on the BIOS on the GHz editions. Or that they have gotten worse bins or somehow made a cooler revision.

AMD is working on three new Radeon HD 7900 series SKUs. This includes the dual-GPU Radeon HD 7990, the Radeon HD 7970 GHz Edition and the Radeon HD 7930. The 7990 is reportedly delayed until August to make it perform within "acceptable" range of the GeForce GTX 690, while the Radeon HD 7970 GHz Edition could be just around the corner. The 7930 on the other hand is expected after June, when NVIDIA's upper-mainstream SKUs become available.
The Radeon HD 7970 GHz Edition is aimed against NVIDIA's GeForce GTX 680. AMD will raise the reference clock speeds for the HD 7970.

7930 sounds intriguing, but would be an odd fit when there's very little pricing (or performance) space between 7950 and 7870 as it is (on newegg at least a few days ago, one model of 7950 was as low as $340 after rebate, while 7870's typically ran $329).
Really the glaring gap in ATI's lineup imo is between the 7770 and 7850. Coming from a 4890, I either pay 129 for a 7770 that is probably a sidegrade, or have to pony up 250 for the 7850. That's a huge gap. It would be great if I could get something actually worth buying for $150 or $180. Even $200.
It would be nice if Nvidia either fills that gap, or introduces something that pushes the 7850 price down.
But about the ghz edition, I think it is a great idea and applaud AMD's aggressiveness.
It continues to amaze me that AMD actually gained on Nvidia in performance by a significant margin this gen than last (if not tied), yet somehow the feeling on the street seems like Nvidia routed them. A lot of that is due to the simple fact you have one card clocked at 925 going against one clocked at 1058, and which boosts even higher. Most people dont parse the fact you can get much more out of the 7970 through overclocking, they just look at stock benches.
Still think AMD maybe needs a boost like technology, but for now 1075 mhz 7970 is great. People will actually be forced to realize it's arguably as fast as 680 and faster than 670. That should enable it's price to stay up at least ~$450 too rather than having to sink farther due to perception 670 is faster. For example I tallied up one of those early ghz reviews, the non ghz edition won 9 of 20 tests vs 670. The ghz edition won 14 of those 20. At least Joe Schmoe should get the hint it's faster than 670.

7970 @ 1750 MHz on a "slower" Z77 platform is quicker than a 1957 MHz 680 on the faster X79 board:
http://hwbot.org/benchmark/3dmark11_-_performance/rankings?cores=1#start=0#interval=20
btw, that leaves the clock difference about the same, stock versus extreme overclock is about 20% higher clocks for the 680.
The 7970 has a higher performance to overclock ratio. With the new GHz edition (assuming it's at 1075MHz) should do fairly well at 1200 & higher.

And a lot of that is due to the fact that nVidia schooled AMD's top dog with a mid range chip while laughing at the bank.
Last gen nVidia struggled to come up with a dual GPU solution and now things seem to be reversed and so on.
That helps.
Yep tesselation off, but well this is a 3770K vs a 3960K this mean 3K points lower on Physic and some on combined.
But anyway, i think this is the only score i have seen with a 680 at this clock speed. 7970 and 680 under LN2 clock nearly the same in most case. ( let say around 1700-1750mhz )

Physics score is not very important for the P-score and the higher clock speed of the 3770K gives it an edge in the graphics score and certainly doesn't hurt in the combined. Tesselation setting plays a huge role in the score.
I completely agree, But after compare, if i use a 3930 in 3Dmark11 over my 2600K @ 5.ghz ( with a bit less speed on the 3930 ) i will gain something a bit more of 1K on final score. ( less of what is gained without tesselation ofc )

With hyper-threading enabled on that 2600k? HT makes a huge difference on the score.
ofc

Hmm... This sounds quite odd. You don't happen to have a link to these results? With what GPU (and speed) are these results and what are the P-scores?
LOL. Yes, this again, Nvidia's invisible high range chip really kicks the crap out of Tahiti. Too bad it's invisible.
I heard AMD had a super duper high range chip that's 4x as fast as GTX 680! Take that! So 680 is really competing with AMD's low end.
For that matter Nvidia still hasnt even got the rest of their lineup (anything less than $400) out going on, six months?

It's not invisible. It'll come a bit later. Right now the 294mm2 chip is adequate for high end.
AMD of course has stuff coming up as well, we'll see how those stack up against the big K.
- You cannot compare clock speeds between different architectures like that.
- The 680 is GK104, the successor to GF114. GF114 was the 660Ti. The 6970 tied the 570 last generation. This generation, the 7970 tied (or close enough) what is essentially the 660 Ti of this generation.
Nvidia's execution this generation has been dreadful, yes, but that is irrelevant to the argument you had presented earlier.
On a side note, your maturity level and knowledge about GPUs are incredibly contrasting to that of the rest of the community here...
