I'm not so sure that the 680 will affect the prices on the 7970 or the 7950 all that much. Those two cards have superior compute performance and may appeal to a slightly different market. I doubt that anyone who wants compute performance will, other than begrudgingly, choose a 680. IMHO, nVidia may be shooting themselves in the foot by forcing those who want the superior compute performance to buy whatever is the 685 equivalent, or one of their pro cards.

At this point, I think the 680 is off my list even because of the inferior compute performance.

For games alone, it is pretty obvious that the 680 is king.

Pretty impressive. I personally can't make myself buy a $500 graphics card, but I'm glad this will probably force AMD to drop the price on Radeons.

I totally agree. The 7k series cards are a better all around card, out of box. And 680 are better gaming cards out of box. But AMD far excels in compute, and they are still close in games. But here's the thing, there is less headroom on the 680 for OC. If one were to max OC both the 7970 and 680, the 7970 would be as good or better in game performance as well. AMD has always left more headroom from factory for clocks.
 

The gtx 560 ti is as good as it gets in regards to over clocking. No other card out there can touch it, and last time I checked the gtx 560 wasn't an AMD card.

Yeah, and last I checked this isnt the 560Ti. its based on the architecture, and they clocked 680 higher at factory than they did with a 560Ti.
They released the 560Ti from factory with a 822 base clock.
They released the 680 from factory with a 1006 base clock...
so you tell me, they already took up some headroom to "OC" it at the factory just to beat 7970.
Running at near anything like the 560ti, it too will also get trounced in graphics.. or OC them both and see who the winner is..

Not to mention you still seem to avoid the point that the 7k series trounces 680 in compute ability.
STOCK:
7970 60%+ compute over 680
680 10% gaming over 7970.
hardly a new king in the 680....

Not just for curiosity, what can you do with all that compute ability that you talk about?

I have media espresso with 2 hd6870 by encoding a video one of the card get's used by about 2-5%.
So the cards are not making a real difference when encoding.

Tell me the programs I can use, for now that i have amd cards, to profit from this compute performance you talk about :)

I really wonder and would like to use the cards for other than gaming...

That picture of yours clearly states that the 680 has GK110 when it has the GK104 so you're already wrong without me or anyone else needing to explain much of anything to you. That picture also has the clock frequencies wrong, it claims that the Nvidia cards have hot-clocking (Kepler does not have hot-clocking), it claims that the 680 has a 512 bit memory interface(it has a 256 bit memory interface), and it has the amount of cores wrong.

Folding, bit mining, all sorts of things. If possible, I recommend leaving encoding work to stuff like quick-sync.

For most games, the 680 is the king at stock performance and that's why it was called the king. Also, the 7970 has about 450% greater DP performance (due to Nvidia putting a crippling 1 to 24 SP to DP performance ratio, but that's how it's going nonetheless).

[citation][nom]murambi[/nom]@blazorthon Yeah its true that if overclocked the 7970 can outperform or equal the performance of the 680 but who is this who is gonna buy a more expensive card so that they can overclock it just to reach the performance levels of a cheaper card. the 680 is a very impressive card considering it was meant to replace the 560ti/570. If im not wrong the 7970 is the best that amd has to offer right now in terms of single card performance. We all know that Nvidia has its main 250w behemoth hiding somewhere waiting to be released.[/citation]

You make a good point, but I was assuming that AMD would drop the price sooner or later, then the 7970 would be worth buying and overclocking if the driver problem is fixed (at least somewhat). The Tahiti supposed has 2304 cores and the 7970 has 256 of them shut off, so both AMD and Nvidia have something hidden from common view right now. AMD could also make a 7970 that has a 1300MHz clock at stock, then they would be competitive with the 680 at stock. Heck, how about the 2304 core Tahiti with a 1300MHz clock or so, should give it a minor lead over the 680. Of course, a 680 TI or 685 with a much more powerful GK110 would probably pull well ahead in current games, but I must ask a question again. Just how long is it until more and more games become more computationally heavy? We have things like physx and more being put into use.

Please, lets see a physx comparison of the 680 and 580. Does the 680 even support it? I'd like to know why Nvidia, despite having been much more computationally heavy in previous generations, has decided to pretty much abandon one of their greatest strengths.

You kind of missed the point. It is only stock performance because NVidia set the clock real high at factory. Essentially the card comes overclocked, and LOWERS clock speed when it has to because of things like temperature, performance, etc.. If you read the article, instead of just looking at the graphs, you would have noticed that it performed worse when 'overclocked', because they clock regulator is based off of the max clock setting and adjusts accordingly. There is not a lot of headroom left in the 680 as I understand it. They used the same arch as a 560Ti but overclocked it by 22% for the 680. There was some room left by shrinking the circuit to 28nm, but scaling isn't linear.

That being said, if Tom's were to OC max both cards 7970 vs 680, id be willing to bet that the 680 wouldnt scale wel. The 7970 would be right there with 680 in game performance, and still destroy 680 in every other category. In reality, it was AMD's mistake, by not making their cards 'stock' at about 5-10% faster.

No. There is no it comes overclock crap. The 7770 and 7870 have huge 1GHz clocks strait from the factory, do we call them overclocked? They're very close to the 680 in raw clock frequencies. No, we don't. Overclocking, by definition is increasing the performance of something beyond it's factory default settings. So, if the 680comes out of the factory without a lot of headroom, well that doesn't means it came overclocked, that means it probably won't overclock very well so it doesn't have much room for improvement.

As for improvements, I bet that the 680 would scale exceptionally well with however small of an overclock it can muster. Sure, it probably wouldn't be a large performance gain, but scaling does NOT mean large, it means fairly linear. Basically, two 6970s/6950s could be said to scale well because for the longest time, there was nothing with more linear scaling than the 6970s and 6950s.

Also, I'm not sure if I'd call AMD leaving huge headroom a mistake. If they lower the prices below the 680, well then that means that if you overclock your 7970 to the point where it actually beats a 680 (might not be a safe overclock), it would be faster at a lower price point. Of course, this is relying on price cuts that if they do happen, probably won't be until the stock of 680s can keep up with demand (or get close to keeping up).

Also, the 560 TI uses the Fermi arch and the 680 uses the Kepler arch, yeah they are NOT the same. Fermi and Kepler are similar in many ways, but not the same. The 680 uses almost 15% more power than the 560TI, but how much faster is it? About 60% faster. That's some very good scaling from the new architecture and the new process node. Also, the GPU boost does not lower the clock frequency based on the workload, it increases it based on the workload. AT load, the 680 will not go below 1006MHz, it's reference base clock. If it's not at load, well, other cards also drop down when they're not at load so it's not a GTX 680 only thing and not even a Kepler only thing.

The AMD cards do similar things with Power tune and Zero Core. The difference is that the AMD cards don't really increase their clock frequencies over stock frequencies (well, stock factory default frequencies since some cards are factory overclocked, meaning overclocked beyond the reference clock frequencies).

Basically, your entire argument is based on false information that you are trying to spread despite it being wrong.

[citation][nom]Why_Me[/nom]I posted a link twice on this thread now to guru3d in regards to over clocking the 680. Guru got a 20% increase when o/c that card without touching the voltage.[/citation]

yeah, and that picture is outdated/wrong. it is still showing the 680 as a GK110. ITS NOT A GK110
so keep posting it. the 680 as released will not OC 20%.

EDIT: (This is where fuzznarf's comment ends, blame fuzznarf's poor citation organization for this discrepancy)



The 560 TI and the 680 aren't based on the same architecture so you already lost. Kepler is more or less based on Fermi, but to say that Fermi and Kepler are based on the same architecture is wrong. Are they similar? Yes. Are they different despite some similarities? Yes and nothing you say can change that fact. There are plenty of differences and that is also why they have different names. Can Kepler be called a gaming improvement upon Fermi? Sure, but an improvement and that which it improves on are not the same, otherwise there wouldn't be an improvement!

http://www.anandtech.com/show/5699/nvidia-geforce-gtx-680-review/14

I only checked the last few benchmarks in the test (I read the whole thing before thinking to check it and only went back a few times) and got about 60%. Now I've checked all 13 gaming test and got a higher number, ~79.5% and by your reaction and this article here, that is a more accurate number. Sorry about that, I didn't expect the last few tests to be so radically different from the first ten or so.

Me saying I bet it would scale well isn't spreading misinformation, it's saying my opinion. I didn't say that it WILL scale well, I said that I expect it too. I based that on the fact that increasing the GPU clock frequency scales well with pretty much every video card I've ever overclocked myself and on these online reviews. It's simple really, GPU clock frequency increases tend to scale performance within 50% of the clock frequency increase. I based that opinion on years of mine and other people's experience with graphics cards.

Looking at the Guru3D review, it seems that the 680 actually does have more overclocking headroom than Tom's thought so long as you didn't use the same overclocking methods used here at Tom's. I think that the Guru3D review is correct about this because it actually made note of how the EVGA Precision program that was used in this Tom's article didn't make much performance difference, but increasing the base clock like conventional overclocking did make a difference.

The picture posted by Why_Me earlier was junk, but now that I've read the Guru3D review, I think that the 680 could have some headroom.

Also, as for me saying that the 7970 being overclocked enough to beat the 680 MIGHT not be a safe overclock, not that it WON'T be a safe overclock. A 5-10% overclock isn't even enough for the 7970 to catch up to the 680, let alone beat it, if the 7970 couldn't beat the 680 in most games even with a 1125MHz GPU clock (slightly over 20%) like this Tom's article says. By that, the 7970 may be able to catch up to the 680 with a 1300MHz GPU clock (and correspondingly greater memory clock), but to actually beat the 680 would need an even greater overclock. Considering that most of the people who really pushed their 7970 only went to about 1300-1400MHz, going beyond that could be an unsafe overclock.

I didn't say that going to 1400-1500MHz so the 7970 will beat the 680 will be an unsafe overclock. Think about it. Most people don't get near that high on air cooling and so I think it might be unsafe. Also, when I say beat, I don't think a 1% or even a 5% improvement, I mean a greater than 5% advantage over the other. Unless the 7970 has a greater than 5% lead in most games when overclocked than the 680, then it's not beating it, it's just too close to see the difference in real life so it doesn't matter.

Obviously NOT misinformation in what I said about that either. Instead of looking at my comment and wondering how it might be right in legitimate ways, you look at how it's wrong in illegitimate ways so you miss how most of it was right because you WANTED it to be wrong.

YOU said that the 680 comes overclocked and lowers it's frequency based on the workload when it actually increases it based on the workload. YOU also said that the 560 TI and the 680 use the same architecture. You did NOT say that they're based off of the same architecture, in which case you would have still been wrong anyway because they aren't based off of the same architecture. Like I said, Kepler and Fermi are similar, but not the same, nor are they based off of the same architecture. Kepler is based off of Fermi. To say that they are based off of the same architecture implies that they have a common heritage instead of one being the heritage of the other.

You are the one who has spread misinformation and then lied about it. I cited your own comment and then you denied what you said despite it being right there for all to see. That's one of many serious problems with many people today; they enjoy an argument more than finding the truth in the argument.
 


Having now read that review, it became obvious to me that Guru3D used a different method of overclocking than Tom's did. Guru3D also made mention of the Precision software that Tom's used saying that it didn't make nearly as much difference as their unreleased version of Afterburner did. Perhaps the 680 does have more headroom than this Tom's article suggests it does. However, you still have little credibility especially after posting the picture about the incorrect "leaked" Kepler specs earlier and that is also the picture that fuzznarf was referring to when fuzznarf disregarded you in fuzznarf's last reply to you. That is why nobody has been listening to you despite talking about a Guru3D review that shows something that seemed to contradict the Tom's review because you didn't explain WHY the Guru3D review showed something different.

If the 680 truly has more headroom than we thought, then even with a proper overclock, the 7970 won't beat the 680 if the 680 is overclocked. Also, that review shows the 680 improving it's performance by about 15-20% (depending on the game and to a lesser extent, the resolution/quality tested at), not just 20% across the board.

Its a midrange card, anyone who disagrees is plain wrong. Thats not to say its a bad card, what happened here is nvidia is so far ahead of AMD in tech that the mid range card purposed to fill the 560ti in the lineup actually competed with AMD's flagship. If you dont believe me that is fine, you will see in a couple months when the actual flagship comes out, the ones with the 384 bit interface.


Oh really scotty? Im pretty sure that with the GTX 680 being labeled as it is, it's their single-gpu flagship. In other news, AMD drops the price of their Graphics cards by atleast 70$.

Just giving a bunch of graphs doesn't count as proof. For all we know you could have F***ed around in MS Paint for a while and posted them. However, who is to say that there is a modern title that is even AMD optimized, because most are Nvidia optimized. So for all you people know, AMD's cards could be 20-30% better, just because of Nvidia's bribing of Producers and Devs they get short changed.
 

Personally I could give two craps less if someone on here doesn't take the time to click the link and read the review. It's on them to read it, not me to post every page and word of said review. If someone has a problem with that review they can take it up with the boys over at guru3d.

And yes every game has a different result with the 680 in regards to FPS when it's over clocked. That's been the case with every card in the past. Different games give different results.
 

Save the poor AMD troll post for some ghetto board please. The last thing I want to read on here is some bs about Nvidia paying off game makers. If I wanted to read that crap I would go to slashdot.
 


The fact that the graph is from Guru3D (unlike you, I actually looked at their review) shows that Why_Me didn't make the graph unless he/she works at Guru3D. As for AMD optimized titles versus Nvidia optimized titles, I completely agree. I don't know of any modern games that are specifically optimized to run on AMD cards better than Nvidia cards, but several are optimized for Nvidia cards or crippled for AMD cards, pick your poison there. However, not all games are Nvidia optimized. Not even all of the games where Nvidia wins are optimized for Nvidia. To say that Nvidia might almost always win simply because almost all games are optimized for Nvidia is ignoring this fact.

I have to wonder if AMD would bribe producers and devs if they could afford to do it like Nvidia can. Remember, not only is AMD worth about half of what Nvidia is worth, but AMD also has their money spread out among more parts of the tech industry than Nvidia, so they might not bribe these guys simply because they can't afford to. Correct me if I'm wrong, but didn't AMD (or was it Ati at the time?) do the same thing before these last few years? I'm not justifying Nvidia actions (far from it), but I don't think what they do always makes a big difference because some (relatively few, but it still happens) of the supposedly Nvidia optimized games often favor AMD cards in many situations.
