7990 1ghz edition to debut at computex 2012

[Roadhog]

Not to mention Skyrim, which came out last November, and was the hottest selling game last holiday season.

Huh? Pretty sure both cards can run skyrim 1080p at 60fps constant. :|

[Lanek]

Its not like 7970 or 7950 is exactly struggling in Skyrim unlike what GTX 680 does in Metro, serious sam 3, and Crysis 2.

in 1900x1200 the 680 win easy .. but at 2560x1600... this is another story . But Skyrim is so cpu limited .... at 1900x1200 you need SSAA for really push the gpu ( and there again the 7970 and 680 are at respectively 66,7 and 67.1fps )

I will not call 2fps faster, something to care about. Specially it is not really simple to test this title.. results will really depend where the reviewer have decided to run the bench.

[cegras]

Going from 0 -> 8xMSAA the GTX 680 takes a 20 FPS hit vs. 8 for the 7970? What's going on?

Memory bandwidth most likely.

Don't worry, no matter what the benches say you still get a better and smoother experience with NV cards...

[dasa]

most people here that play skyrim will also mod\tweak it and after doing that it can use well over 2g gpu mem meaning reference gtx680 can become unplayable if you take the detail to high
be interesting to see how the 4g model would go against the 3g 7970 in this situation and how much of a hit if memory bandwidth would be

the 7970 is completely cpu limited at 1900x1200 in skyrim: (Anandtech review ) 1900x1200+4xMSAA = 86.8fps ... 2560x1600 + 4xMSAA = 86.2fps .. lol 0,6fps difference between 2560 to 1900..

look like the cpu is the key in Skyrim..

Is this the same for the GTX 680? It seems to suffer much more with 8xMSAA in Skyrim.

I think in Anandtech review this is due to the fact they use 4xMSAA instead of 8xMSAA in 1900x1200.. for an unknow reason the 680 look less touched at 1900x1200 of the 7970 by this " cpu limitation " (maybe when usage is low due to cpu, the turbo boost then kick in much, keeping an higher framerates on some part at 1900x1200 ) then at 2560x1600, at the moment you put the AA, the 7970 start just to work so it dont take the same hit.
Why such a limitation ? well Skyrim is based on x87 instructions for the CPU, we can imagine with SSE4 instructions the cpu will work a bit faster and improve again the perf. removing this cpu limitation.
But really whatever you use, a 680 or a 7970... you cant be wrong in skyrim with one card or the other.


Anyway VCE is now working with HD7000 + 12.7beta and there's other improvement there. (now performance increase are fully described, and hard to doubt of them as it is shown in the test made by different review of the 12.4 vs 12.7 )

Skyrim is an oddity. At some points it gobbles up resources like crazy (example: the very first scene where the dragon attacks) while at other times it is severely CPU limited. Even with a modded settings .inf file and the Higher Res Texture Pack, it seems oddly constrained at 1920 and 2560 without 8x MSAA enabled.

hopefully for the developers the performance are not bad, i cant imagine what will have happen if the games was running at 40fps 1900x1200.

[BababooeyHTJ]

Has anyone actually done a crossfire review with 7970s at that clock speed? I would love to see how a couple of 680 or 670s compare.

[Olivon]

7950 GHz Edition I guess.

The fact of the matter is that GTX 680 struggles in every one of those games at a higher res. Serious Sam 3 is another one and there are a few more. In the games where GTX 680 does perform better than 7970 it isn't exactly struggling. 7970 performs more consistently at a higher resolution, spin that any way that you like it.

HD 7970 wins more of the demanding games - games which can't hit 60 fps at 1600p. Frankly thats where even a difference of 5 fps matters. Not when the cards are doing 80 - 100 fps. Few of the games in that list are BF3, Crysis 2, Batman AC, Alan Wake, Witcher 2 / Witcher 2 EE, Anno 2070, Shogun 2, Dirt Showdown, Serious Sam 3 BFE, Metro 2033, Crysis Warhead. Nvidia wins Shogun 2 clearly. BF3 is close enough according to most reviews. Batman AC runs much faster with FXAA on GTX 680, but with 8x MSAA its slightly in favour of HD 7970. The rest simply run faster on HD 7970. Some of the margins are quite big, ranging from 10 - 25%. The worst case is Dirt Showdown which is 50+ % faster on HD 7970 wrt GTX 680. We have to wait and see if thats a driver anamoly or a reflection of compute performance and bandwidth superiority of HD 7970. Even though Dirt Showdown is a GAMING EVOLVED title , that margin of performance difference is embarassing. When "push comes to shove" HD 7970 performs better in more cases and with significant difference.

Any selfrespecting review site has done benchmarks on the 7970 cfx oc'd over the past months.
And result is simple. 7970 pulls ahead further with any high res/AA. 1920 is still cpu limited on most games. 7970 can oc further than 680 and 670. And 680 and 670 are still very bandwidth limited on high res.

Instead of making claims like that link me to a decent review. I haven't seen any, especially with recent drivers.

what drivers?
301.10 was march 22
301.42 may 22

the rest is beta and most people dont play with that stuff, and nor do reviewers

You are usually only supposed to use that when the results that come up answer the question, which they don't.

There is not one full review of overclocked 7970s in crossfire in those results genius. Go troll somewhere else.

I'm not talking about Nvidia drivers since to be honest performance is unchanged since launch.

I would even be content with older drivers and actual games at 2560x1600.

I hate using lmgtfy but it's what lazy people ask for. Since you seem to be new to the internet I'll do the extra effort
2nd result has oc results: http://www.legitreviews.com/article/1834/1/
5th result has oc results: http://www.tweaktown.com/articles/45...ked/index.html
6th result has oc results: http://www.overclock3d.net/reviews/g...inity_review/1
Should be enough I think.

And if you wanted 7970 crossfire specifically with beta drivers you have the 6th result from the 2nd lmgtfy http://www.ocaholic.ch/xoops/html/mo...l_lang=english

Not one of those links has a GTX 670/680/690 in it and is with launch drivers. If you're going to be a smart ass at least try and make a relevant point.

WTF do I care how a couple of 7970s with launch drivers compare to fermi? Seriously dude, quit while you're ahead.

I want to see how they compare to the competition that they've had for the past few months. I don't get what is so hard to understand about that. Do you have any more douchebaggy lmgtfy links that don't offer a single answer to the questing that I asked and then be a about it?

[Stijndp]

You can stop swearing at me. I'm too old to be trapped into flaming.
You asked for oc crossfire resusts against 680/670, I gave them. You asked for crossfire performance with 12.7 beta, I gave them.

Don't play out your frustrations on other people.

Notice he said compare in the same review.

This is what bababoey is asking for proof of.

Not one of these reviews actually compares within it, a gtx 680 SLI setup which makes it impossible to draw your conclusion.

Unless you show evidence otherwise, your showing either you made up the above statement or have a bad memory.

The type of evidence bababoey is looking for looks like below.

http://hothardware.com/Reviews/NVIDI...Review/?page=7

Notice the 7970 CF and gtx 680 SLI results are in the same graph. This is what bababoey wants. Unfortunately for you, I have not done the work for you and these results show gtx 680 SLI being generally faster than 7970 CF.

The frustration is simply you not correctly answering his question. You gave an answer that doesn't answer the question and you act like it did. How are individual results from a review prior to the release of the gtx 680 going to prove.

Sorry for the reposting of what you wrote over and over. But what are you posting does not somehow prove the above statement. And calling someone lazy in an argument(and asking them to find the proof themselves), when your the one who made the instigating statement(the statement that causes the controversy) and asking for them to find there own proof is ironic and hypocritical.

Defend your own argument. Don't make the person who opposes it do it for you. They are more likely to come up with results that contradict your statement or show nothing at all.

So, where is 7990 ? Still scheduled or not ?
