In terms of what? In terms of uneven times it makes a huge difference.
FCAT shows otherwise for the most part. Both companies trade places depending on the game when you follow the frame through the whole pipeline.

Why is it that these things ALWAYS end up in an nVidia vs. AMD war?
Why can't we just get relevant information and take it for what it is? Not a single benchmark has surfaced, yet the 7990 is already doomed due to perceived issues. Driver problems, surprisingly, hasn't come up yet, but I'm sure it will now that I've mentioned it.
This forum, back in 2003 - 2008 was a different place altogether.
I, for one, am looking forward to benchmarks and actual real-world tests of the 7990. I've long been a fan of ATI/AMD dual-GPU cards, having owned every version that's been produced and NEVER had a single problem that wasn't my own fault.
Will it compete with the Titan? WHO CARES? What's the point of a thousand-dollar card beyond "I can afford it, so why not!?" That market is so small that there's just no room for competition. And those that have more than 1 of them - they clearly have disposable income greater than the rest of the population. And guess what? That card will be outdated by next year too, just like every other king of the mountain, either by another nVidia card, or an AMD card...

And the battle rages on...interesting to see AMD and Nvidia still slugging it out long after the initial release of the 79xx series.
SLI-756
yes.

Looks good, but won't this just perform the very similarly to the current 7990 offerings from Asus for example? Its just AMD are now making one themselves!? Or am I missing something here?
On a side note, I've ordered myself a MSI 7970 OC from Scan for £275, so anyone interested in a 7970 should head on over there as thats a great price and well I couldn't resist it 😉

Uhm its very noticeable, should i list some reviews saying cf is not as smooth as sli?
The Postman
Yes please do it ... we care a lot...

Probably not because if that's the conclusion you reached then you're reading the wrong reviews. Up until 2 days ago all the reviews have been using fraps to record frametimes and latency. Fraps captures pre windows pipeline. FCAT, an nvidia released tool, shows different results. FCAT allows you to view the frame throughout the entire pipeline.
Arstechnica published an article using the FCAT tool and the results were significantly different than previous frametime articles. CF and SLI often trade places in both frame latency and consistency.
Anandtech also published an article about AMD and their opinion on frametiming. They pretty much said that they favor low latency over a smoother frame experience but they will update their driver to allow the user to decide.
So yeah, it's basically a problem both nvidia and AMD suffer from at this point and they both trade places in latency and stuttering depending upon the title.

He IS right, CF is not as smooth as SLI. Nvidia have made SLI smoother by delaying frames by 1 frame apparently. We're missing the point here; currently, it's advisable to use VSync, flip queues, FPS caps to reduce / eliminate microstutter. Until the driver drops in July, where we can choose between smoothness and latency (SLi goes for smoothness by default).
Microstutter exists, this is a fact, many people notice it, even if it was minor (which it is often not with CF). SLI also has microstutter, but only now are some reviews showing this.

What you're saying is very interesting. Can you please link to the article?

In terms of why its going to get slated to buggery, it could be a single card, doesn't matter.

Why care if it has "issues" or not? it will be the fastest single gpu (dual chip) on the planet, that's all that matters.
Also since we dont know anything about it it could use the same PLX thing like nvidia's GTX690.. But no all bitch it will be crap, actually only nvidia fans always raise their voice, kinda tiresome to read this over and over again..
If someone says anything against nvidia he's a troll, a AMD fanboy, etc., sorry and no offense but you diehard NV fans are those trolls - like parasites :P 😀

Read 80% of the posts in this thread and you will see why I choose not to use Crossfire of SLI.... EVER. :wanker: lol
Its nothing but headaches, even on a forum.
Rich_Guy
Its rumoured to be faster than the Asus Ares.

Sli's been nothing but awesome for me, only issues that arise is from new releases that are waiting on NVidia or game devs to release and update or just messing around with sli profiles/bits can sort things without too much hassle.
As for the 7990, why are people comparing this to the titan? Isnt the 7990 dual core and the Titan a single. I think comparing to the gtx690 is what people should be doing.

I think a 7990 is not worth it when it performs about the same and is more expensive than two 7970 cards.
If you look at these forums than people have issues with their graphics cards and seems it doesn't matter whether that is SLI/CF or single card configs. People have more to write about problems than if all goes well. In that case they are just gaming. 😉

You do realize that goes both ways AMD has their share of fanbois as well a few are on display in this thread. Me, even though I have 670 sli right now that does not mean I would not get one of these cards. I'm a fan of performance when I got my 670's they were the best for the money and that's all there is too it being dedicated to one brand over another on pure principal is just narrow minded and dumb.
-Tj-
thats a 7970 in crossfire, not real 7990. They assumed it will be the same like Asus Ares 2x7970 slapped together and they dont have a clue either if it will use PLX chip or crossfire bridge..
So in the end your point is? Actually dont bother Im not interested, I know you prefer nvidia. 😉
Oh yes i know that very well, but its far wrose when nvidia fans steep in..
I also dont mind one or the other company, I bought this 570 gtx back then becuase it offered better perf. compared to 6000 series, if I would buy a new gpu now i would deffo pick up 7970 ghz, GF600 is not my thing at all. Maybe GK110 but that thing is overpriced for what it offers.
