[VR] NVIDIA GeForce GTX 680 Specifications Revealed

[ShadowOfMyself]

Well thats interesting... And to think AMD was getting slaughtered in tesselation just a year ago

He said heaven, and Tess mark.. Not exactly important factors as the AMD community has pointed out since GF100.

Could be too much die space went into tess units, if they don't have a lead in Crysis 2 or BM:AC it's not going to bode well for the rest of the DX11 benches.

Didn't stop Heaven and Tess mark scores from littering the web. ;p

Where did he say this, do you have a link?

 

[notty22]

Fans forget that AMD initiated showcasing Heaven with the 5870, since that and the Dirt 2 demo were the only DX11 content at it's launch.

Wouldn't it be funny if Nvidia removed tessellation die space to get more general performance, i.e., what AMD had been doing? A complete reversal? I wonder how the GK104 will perform in Bitmining now.

 

[BallaTheFeared]

It wouldn't be funny at all, I enjoy tess even if it's just in it's infancy on the support level 🙁

GF100 totally destroyed tess, longs before it really even needed to. It's starting to shine, titles like Crysis 2, and Batman AC really show the large performance gap in that respect between 4xx and 5xxx.

I would hope tess performance is at the very least the same as GF110's full 16 poly engine performance, the 480 had 15 and the 470 has 14.

Since gk104 isn't out, I'm sure drivers still have some work to be done. The same can be said for AMD's GCN ---> going on over 2 months now with 1 official driver release?

Well the 295.73 WHQL drivers took 3-4 months to come out with only 1-2 beta releases between the last WHQL release.

That suggested the driver teams were busy working on something else.

There are rebates across the board on every GTX 500 series GPU regardless of manufacturer currently, which is a telltale sign something new is about to release.

Interesting. Sounds like the GTX 680 will be competitive with a 7970 and my guess is NVIDIA will sell it for $500 USD. Wonder if it will also pull 40%+ overclocks.

I don't think it will pull that high OC since I assume it will be already high clocked to surpass the 7970, remember this is the performance chip which wasn't meant to compete with the high-end AMD. On the other hand I think it will be priced lower than 500$.

 

[boxleitnerb]

How many 7970 can do 40+%? C'mon, lets stay realistic here. What is the average OC a 7970 can be expected to do with reasonable voltage for 28nm (be it stock or raised)?

It's possible.

That depends on how much noise you can stand and/or your cooling solution. 1200MHz is probably reasonable with voltage and quite a lot of noise with a reference cooler. Probably more acceptable with better cooling (Windforce 3, etc...). You are right though, no 40% typically unless you are under water.

Still, these cards can pick up a lot of performance O/C'ing (~25%). If the hot clock rumors are true, I'd be surprised if GK104 can do that. Not impossible, though.

 

[BFG10K]

I can’t wait to see how it compares to a GTX580. Also if it’s a new architecture, I hope it doesn’t have driver problems like the G80 did at launch. That was terrible.

You mean for windows 8? IIRC, G80 launch was during newcomer Vista.

 

[Rifter]

Dissapointing just like the 7xxx launch. Still waiting for double 580 performance in a single GPU, and will lay down cash to buy such a card as soon as its available, to bad this doesnt appear to be it. Will have to stick it out with my SLI 460's till next year at this rate.

From my sample of 1, I would say 25-35% as a broad estimate with some voltage tweaking.

1225 MHz @1.25V exhibits no tearing at all. The memory can be clcoked all the way up to 1850MHz @1.6V.

My daily OC is 1125MHz core @1.112V, 1600MHz memory @1.5V.

 

[BFG10K]

No, why would I? The driver architecture of Windows 8 is pretty much the same as Windows 7.

I ran G80 on XP and the drivers were absolutely shocking at launch. About two thirds of my games had some kind of problem that significantly impacted gameplay. It took at least a year to get things to a reasonable level.

Yep, BFG is aboslutely correct. nVidia's driver team did a terrible job when G80 came out, both with Vista and with XP. 'Display Not Responding' threads were EVERYWHERE! Wait, lets sweep this under the rug quickly!

Now that I ponder this, I believe this is why I ended up skipping G80... that and getting married and buying a house and stuff 😛 When it came time to think about upgrading my PC, I just didn't want to dork with it, I wanted it to work.

I have it on good authority that AMD clocked Tahiti low just to spite diehard fans,

and not at all - to have somewhat decent yields with fresh 28nm.

Because everyone knows that other then Nvidia everyone has great 28nm yields.

For instance AMD paper launched entire lineup, but availability is just awesome. Although it may not look that way because of great demand.

TSMC shut entire awesome-yield 28nm production, therefore screwing everyone -
- just to accommodate little Nvidia.

Yes, AMD just loves to clock low, instead of shipping products with 50%:50% probability to boot.

Some users are wary of tweaking voltage, but I would say that the majority of users willing to up the voltage a tad (even just 50mV) would easily hit 1125 at a minimum. I can get around 1125 at stock voltages, however once I over volt I can go far beyond that.

 

[96Firebird]

And yet some forum members here returned their 7970s because they didn't overclock as well as they wanted...

I'm aware that overclocking isn't guaranteed. However, most users just aren't willing to over volt. In my experience most GPU's don't oc to their potential without overvolting, i've oc'ed everything from the 285, 580, and 7970. Overvolting on my former 580s yielded me 100 more mhz.

I'm just saying, of those that had issues with oc'ing, most either did not overvolt or did it improperly (through powertune). There's obviously no way to prove this and no objective data on every single 7970 released - however in my experience, the 7970 oc's *signifigantly* higher when overvolted, yet most users aren't willing to overvolt. In my opinion i'd say the majority overclock easily with additional voltage. It also overclocks on average considerably easier than the GTX 580, the GTX 580 is lucky to get a 100mhz overclock on a reference design while the 7970 *on average* does 200+ easily. My opinion was solidified when I was able to get 1125+ easily on stock voltages, whereas I really had to wrangle with the GTX 580 to get a good overclock (and minimizing heat output). Again, my opinion based on using both of those respective products.

We can go back and forth on this where you pull posts 2 forum users made a month ago (with difficulty oc'ing), and I can pull 3 reviews showing 1125mhz overclocks at stock voltage. Whatever, as I said there's no way to provide proof of every single 7970 ever released on the market. So this is my opinion, the end.
