What do you expect from the GTX680?

[Smartazz]

I wonder if AMD’s compute tax allowed Nvidia to catch up in performance/die size.

 

[taltamir]

You're missing the option of slower.

Considering just how much overclocking room the 7970 has, the fact nvidia uses the same process, nvidia had extra time, and nvidia's history... slower is extremely implausible.

The question should not be whether it will be faster, but how much more power and heat and noise will be required to achieve that performance advantage, whether it will have any overclocking room at all. And will AMD immediately released a higher clocked version of of the 7970 that beats it.

 

[Phynaz]

Cool, now how about the part that competes with the 7850?

I really want to switch to Nvidia, hope they can ship it!

 

[bryanW1995]

I was going to say "slower", but computerbase has a solid reputation. So instead I'll ask the following: what resolution? It could be 18.6% faster at 1080p and 18.6 % slower at 2560x1600 with 8xMSAA.

 

[Keysplayr]

I expect it to be everything every GPU enthusiast gamer expects it to be.
Fast.

 

[NIGELG]

Fast.

What happened to your 590?

 

[bunnyfubbles]

At this point I'm expecting it to be comfortably faster at 1080p, a tossup at 1600p, and likely losing in multi monitor

the real question I'm waiting to have answered is how high an average overclock will we be able to expect from the 680 and then how it compares to the average overclock of the 7970. No 8 pin connectors and only dual six pin connectors on the reference design suggests limited breathing room in that regard and thus might not be that enticing for those of us who like to push their cards

1080P

GK104 and Tahiti both at 1000/1500, GK104 wins by 5%

GTX680 versus HD7970 at stock, GTX680 wins by 18%

You heard it here first!

what about when we clock the cards to consume the same amount of power? nVidia looks like it is going to have a huge performance per watt advantage this round when that has traditionally been a weakness. At any rate normalizing is silly, its all about stock vs. stock or maybe average OC vs. average OC

We don't compare Fermi at the same clock rate as Evergreen or Norther Islands and take it seriously (Fermi would crush even harder), why would we do the same for Kepler vs. Southern Islands

How fast do you think it will be?

I believe Nvidia is pulling the wool over our eyes, the gk104 being a mid-range part that performs exceptionally well, enough so to call it a 680 to command a higher price upon release.

And when AMD refresh the 7970, the gk100/110 will be out in time to counter it.. and beat it, maybe at a higher price.

This.
The GTX680 is not deserving of the name if the leak at THG is somewhat accurate. +30% over the 580 is really great for a midrange part like a 660Ti, but underwhelming for a high end GPU to say the least.

I expect the 680 to be 10% faster than the 7970 in some scenarios, tied in others. There will be very much cherrypicking going on I assume.

On the other hand GTX 580 was 15-20% faster than GTX 480. That would make this GTX 580 -> GTX 680 change bigger.

Are you being purposefully ignorant that gtx480 -> 580 was the same node?

This is a full shrink. Performance should be at 60-100% if its targeted at the high-end segment. Clearly its not.

 

[Xed]

I'd guess 0-10% faster than a stock 7970 but not clocked as conservatively so less oc headroom.

I was saying that GTX 580 -> GTX 680 is performance wise bigger change than GTX 480 -> GTX 580 was.

..and yes it's rather obvious that GK104 wasn't originally meant as high end GPU. poor double precision performance is yet another indication of that.

 

[BallaTheFeared]

I'm not sure where this is coming from, but Nvidia has noticeably more TDP headroom left, if anyone clocked their cards higher it's AMD.

 

[Silverforce11]

Since when is TDP headroom relevant to clockspeed headroom?

 

[BallaTheFeared]

Since when was MHz between different uArchs grounds for presumed OC headroom?

7970 got trashed in perf/watt, Nvidia cards these last few generations have destroyed AMD's cards in OC headroom.

Just a far fetched guess, but it's unlikely AMD is going to have any advantage in any area this gen.

Grasp though if you must.

"Far fetched guess" and you say others "grasp"? Seriously do you listen to yourself?

 

[BallaTheFeared]

No I don't listen to myself on a text based forum, that's silly.

So you don't hear that voice (of reason and logic) in your head when you type things up?

Figures.

 

[BallaTheFeared]

Nope, I don't hear any voices of reason and logic when I post, but I do see a burning bush and the words I post come to me through a big booming voice from the sky.

 

[Meaker10]

Pulling even with 7970 factory overclocked cards and pushing down prices generally would be ideal!

 

[boxleitnerb]

The 580 was not really deserving either. But I guess we need to get accustomed to the fact that names mean squat anymore. Anyway, as silverforce said - different node, new generation. So 60+% is expected.

 

[nenforcer]

I will be curious as to the Eyefinity benchmarks versus the nVidia surround.

I expect AMD to have a more rubust solution since it's what, 3rd generation now, compared to nVidia's first.

They will also have 3GB VRAM which could help quite a bit compared to only 2GB for GTX 680.

 

[sontin]

And now we get something around 40%+ (twice of the GTX560TI) (and i hope 60% ) for 27% less power. And if you clock the card 14% higher you will get the 60% or more.
