Nvidia Kepler - Geforce GTX680 Thread - Now with reviews

If it's 600 dollars in the US, I think some serious price fixing is going on.
The real indicator is going to be if they release it and the price on the 7970 doesn't drop. They've been sued for price fixing before and they settled out of court.

As someone here mentioned before, the real bargain is going to be found when people dump their old cards on eBay at deflated prices to pick up the new hotness.
 
Thanks.

Wow. If this is true, Kepler is looking pretty damn impressive. 7970 (or better) performance in about 800 Million less transistors and 55 less watts.

Also tells me that there's a lot of room for AMD to improve witha 89xx series.

This is very impressive. Looking forward to seeing if they can deliver at the ~$200 mark.
 
Those Kepler benches are a little fishy.

They're all at 8XMSAA which is a little odd, and I think 7970 tends to do worse with high AA for some reason.

All those games tend to traditionally favor Nvidia. Lost Planet 2, BF3 do, and I'm not so sure about Batman I think it might too.

They're all at 1080P, which we were expecting GTX680 might struggle at 2560, and conveniently there's no 2560 benches.

The 3D mark scores should be OK I guess. All I'm saying is in a full review 7970 might look better. Plus Dave Baumman hinted on B3D AMD might be looking at bumping 7970 stock to clock to 1ghz (apparently they had to make the clock decision early on, before they knew 7970's full clock potential), which would also help 7970 a lot vs 680. ~10% would make them ~even in 3Dmark.

AMD might have to cut 7970 at least $50 though if these stand up.

The turbo mode seems nice, now I get it. Seems a lot better concept than AMD's powertune stuff. Wonder if it will effect overclocking though?
 
Two price points have been posted now.

507€

607€


Just posting this for those who go WTF on the latter one.

I wouldn't base much on the pricing so far, especially not to how it will relate to USD/CAD pricing. Certainly no need of freaking out...just yet.

One could argue their yields are probably terrible on 28nm I'm guessing.

Yea, but in this case is not so clear cut. People that take that route will miss on the benefits of the new lithographic process, so in this case there's a bit more in the mix than getting a more powerful card. That would have been more plausible , for example,in the 5000/6000 transition. That's of course if the 6000 series wasn't such a reduced improvement.

Let's hope not! It will serve better our interests if that indeed was the case :) Owners had been enjoying the fastest cards around for months so they shouldn't feel bad if it causes a price reduction.

Exactly. Newegg was selling a GTX 480 the other day for 209.99. That would be a decent bump up from my 460, but there's no way I would touch a card with that power draw. I don't care if it was given to me for free (I'd just sell it on ebay).
 
Really can't wait to see the 2560x1600 benchmarks, that's my final purchase decision. Sure 2GB could be a potential bottleneck but my 580 1.5 isn't doing bad at all.
 
I know the 680 has higher fillrate...Im asking why because it seems the 7970 has better on paper specs.

Transistor count
4.31 vs 3.54

Shader Count
2,048 vs 1,1536

Ram
3 gig vs 2 gig

Bandwith
264 vs 192

Memory Type

384 vs 256
1. Transistor count doesnt matter because you could spend a lot of the transistor budget on non-gaming related areas.
2. Shader count also doesnt matter because the shaders in each are different. Apples to oranges really. Nvidia fought off 1600 AMD shaders (5870) with 480 shaders (GTX480), didnt they?
3. VRAM buffer counts, but I doubt it will show its limitation for 1080p and below resolutions. We also dont know the multi-monitor performance yet ..
4. Memory bandwidth does matter but again it starts to show under specific conditions. I remember there were some 7970 benchmarks where they underclocked the memory and the results werent that significant.

Not everyone is as aware of that site as you are. I hadn't even heard of HKEPC before today.
Just an FYI, they've been around for 8+ years.

What if ... these are guidelines from Nvidia's review guide given to the press?

You can buy like 6 5850s/GTX 460s for the price of one 7970/670. It doesn't get much more clear cut than that.
 
I'm sorry, but your know-it-all attitude is pretty funny.
What, how did you get that? Didnt mean it to come off like that.

Just do a search on "hkepc" on GAF and get results from '05 .. :D But I've read their articles since the X800 generation.
 
At least not within any kind of reasonable timeframe. Maybe a year or two from now you'll get performance on par with the 680 for $299. Even a year is very, very optimistic.

I think you misunderstood what I said. I'm not saying I want this card for $200, I'm asking if Nvidia can deliver as equally an impressive card compared to the competition (cooler, better performing) in the $200 segment.
 
Guess what, bitches... GTX 680 might come in at $400-450. More details in a couple mins. I will buy Kepler DAY FUCKING ONE if it comes in at $400-450. NOM NOM NOM

Just a note:

Looks like Kepler is going to win on price, perf/watt, perf, price/perf, die size, power consumption, and drivers... FXAA is now in the control panel too.

I'll let the pics speak for themselves. Drivers are not necessarily newest per forums, so some results supposedly are "low" via early reports, and OC has been seen up to 1350-1400mhz possibly:

EDIT with additional info regarding a new anti-aliasing method:

Practical function open: new antialiasing technology TXAA

In addition to the graphics performance, NVIDIA also for the needs of gamers, add a number of new and useful features for a new generation of the GeForce GTX 680, released a new anti-aliasing technology TXAA, a new generation of hardware rendering anti-aliasing technology, actually belongs to the old MSAA's enhanced version provides better anti-aliasing I can reduce the open antialiasing fluency decline, for the time being belonging to the GeForce GTX 680 unique anti-aliasing, but NVIDIA said that the above will be open at a later time to the GeForce GTX 500 or Model.

TXAA temporarily can be divided into two levels: TXAA 1 and TXAA, the former costs only 2x the MSAA similar, but the MSAA is better than the 8x anti-aliasing; As for TXAA 2 effect is more outstanding, but the cost only similar with 4x MSAA. TXAA game itself support to be open to use, support TXAA variety of games will be held during the year stage, although present, failed to test its real performance, but based on the NVIDIA official photos can be seen, antialiasing does, it is worth looking forward to.

In addition to the new TXAA Antialiasing, NVIDIA is also an existing graphics card users to bring good news, the introduction of the original few games before the corresponding FXAA to the NVIDIA Control Panel, users can easily turn the feature on. lead to better anti-aliasing for different games, and enhance the quality of the game screen.

GoldtenTiger is the biggest Nvidia fanboy on [H], not sure why I would believe him or his findings.
Put me down for one Kepler if its priced at $400.
 
I'm in for 2 at the 400 dollar range.

Scogoth is in for 4 at $400. You guys should do a group buy.

BTW I'm cumming if this is true. 2 GB of VRAM be damned, I'll OC that bitch to 1.3 Ghz core/7 Ghz RAM and have a monster on my hands.

Perhaps. But still... if true, it's awesome. If not true... meh.
 
I want to know more about TXAA.

I'm not going back to FXAA until the texture blurring is improved.

TXAA, which we talked about a little earlier, turns out to be a super-efficient temporal anti-aliasing algorithm. It has two levels: TXAA(1), and TXAA2. TXAA1 provides the image quality comparable to 16X MSAA, with the performance-penalty of 2X MSAA; while TXAA2 offers image quality higher than 16X MSAA (unlike anything you've seen), with the performance-penalty of 4X MSAA. Since few games natively support it, you will be able to enable it through the NVIDIA Control Panel, in the application profiles, provided you have a Kepler architecture GPU.

So yeah..if true then this is freaking super sweet
 
Damn, TXAA is exclusive to Kepler.
Umm ..

Any word on multi screen support? If i can play games on triple screens with one GPU like AMD does then im returning my 7970 and waiting for this.
 
So TXAA is some type of temporal AA? I dont think thats kin to FXAA (edge detect).

Might have ghosting issues if anything, thats the potential prob with temporal AA.
 
What's going on in here, guys?

My guess is that Epic games is using a GTX 690 which is said to possibly be launching in mid May to power the Unreal Engine 4 technology that was shown off behind closed doors at GDC this year. Sounds like a nice upgrade over my aging GTX 590. Bring it on!
