Have you seen 680 at 1.3GHz somewhere?

Hmm interesting... how high does the 680 overvolt to at 1186MHz base clock and what voltage was it drawing at 1.2/1.3 GHz?
OK, let me know when you see 1.3GHz 680.That's not how it works. You have Base Clock + GPU Boost on top.
So if it's overclocked to 1110mhz, it can easily hit 1210mhz, if it's overclocked to 1186, it can hit 1277-1304mhz in games, and so on.
^ That's on reference GTX680s. Non-reference 680s with better VRM and power phases may even be able to hit more.
Of course, you can spend $80 more and cross fingers for a 1250mhz 7970. Then HD7970 might actually win.

The way I look at it, HD7950 would need an 800-->1200mhz overclock just to match a stock GTX680. All that for just $50 more (plus all the other benefits with features, EVGA, etc.)? Who is going to buy a $460 HD7950 with non-reference cooler just to overclock it 40% to say look my card is just as fast vs. guaranteed performance out of the box?
It's not a slam dunk because GTX680 should have been a $399 GTX670Ti. The performance delta over the GTX580 is evident that this isn't the real Big K.
500mm^2 GTX685? If GTX685 has 2304 SPs, 384-bit bus and proper DP performance, that's going to make GTX680 and HD7970 look like toys.
I can't believe how much defending on this forum went towards HD7950's $450 pricing, a 14-month older card only 5% faster than a GTX580. After NV lowered GTX580's prices to $360-370, it was already questionable. Finally, GTX680 seals HD7950's fate and echoes what many have been saying all along - HD7950 is just mid-range next generation performance at next generation high-end prices.

This is gonna vary from card to card as chip quality differs of course. But at least they compare more than one game. 7970 doesn't look as bad when both cards are going all-out OC. But it's still clearly losing in BF3. Check out the AvP differential though, as that finally pushes the GtX 680 beyond its 2GB VRAM.
TPU also found that 7970 catches up a bit when OC vs OC:

Yes, and it's slower than 1.8GHz 7970.Maybe we should all that a step back and see how this plays out over the next few weeks.
(not a realistic clock speed, but it is over 1.3GHz per the request)

1.15V @ 1277mhz
on a reference card with reference blower. That's insane.
That's lower than HD7970's stock voltage. That likely explains why an 1186mhz GTX680 with GPU boost still consumes less power than an OCed 7970. Most 7970s need 1.25-1.3V to reach 1250mhz on air.
This is from software, so may not be 100% accurate.
up to 2F90 (up to 75% quality) - 1.1750V
up to 34D0 (up to 80% quality) - 1.1125V
up to 3820 (up to 85% quality) - 1.0500V
up to 3A90 (up to 90% quality) - 1.0250V"

You know nV has a winner on its hands when people who normally rail against them are posting screenies of them ordering 2.
Kepler is a great chip. I can't wait until we see it at its full potential.
That was done by kingpin with a special modded VRM soldered on the board and a special BIOS. Wizzard is saying that the standard BIOS has a hard GPU boost limit coded in... Did you read the entire article....:thumbsup:
Even 1.3GHz with boost will be very hard to find.Review.
If you are talking about 1.3Ghz Base clock + GPU boost on top? That's >1400mhz on the core. Not sure if serious expecting this from a reference card with 4 power phases an air cooling with 2x6-pin power connectors.
$600 Lightning card with LN2? For sure, many of us have a friend who knows a friend who works at a factory where we get free lifetime supply of that stuff.
1.15V @ 1277mhz
on a reference card with reference blower. Now they just need to release Direct CU II, MSI TwinFrozr or Gigabyte Windforce 3X for this chip.
That's lower than HD7970's stock voltage. I am guessing this explains why an 1186mhz GTX680 with GPU boost still consumes less power than an OCed 7970. From what I've seen, 7970s need 1.17-1.20V to reach 1150-1200 and 1.25-1.3V to reach 1250mhz on air.

What's the performance clock for clock?
