Bandwidth is Bandwidth, and Capacity is Capacity. They each serve their specific purposes, and are not interchangeable in the manner you seem to be suggesting here.

You cannot, IOW, make up for a lack of capacity by adding bandwidth, nor can you make up for a lack of bandwidth by adding more capacity.

Yes the 4GB will help, but justifying the much higher price is not worth it.

In my opinion, if you really want full capacity of Vram, the Titan with 384bit and his 6GB is just the BEST FREAKIN card on the market for HIGH resolution thumb.gif

Glad we have some sort of a consensus thumb.gif

However, their conclusion flies in the face of all the people, including yourself, who are making the "256-bit is not wide enough for 4GB" argument. The guys at [H] are clearly suggesting that they believe the 'problem' with the SLI 4GB 670 setup is the actual GPU's performance, not the available bandwidth.

That's why they're suggesting SLI 4GB 680's, or Tri-SLI 4GB 670's, in order to have the gpu grunt needed to properly 'make use' of the 4GB.

Correct me if I'm wrong, but it seems to me that if they thought 'the problem' was the bandwidth/capacity ratio, they wouldn't be making these suggestions, because neither of those options would address that problem wink.gif

It's impossible to find a review with 3 x GTX 680 2 GB VS 3 x GTX 680 4 GB for multi-monitors





Pay attention to this review.

Final words and conclusion



This is the second customized GeForce GTX 680 board from Palit we have in our hands, and it certainly does not disappoint. The card performs 99% reference though, due to the default clock frequencies. Honestly it is a bit of a missed opportunity to see the default clocks as the 2GB version comes factory overclocked for you. So that leaves the JetStream cooler, which does an awesome job and of course that massive whopping 4 GB framebuffer.

The 4GB -- Realistically there was not one game that we tested that could benefit from the two extra GB's of graphics memory. Even at 2560x1600 (which is a massive 4 Mpixels resolution) there was just no measurable difference.

BUT AGAIN: Now the setup could benefit from triple monitor setups at 5760x1080 (which is a 6 Mpixels resolution), but even there I doubt if 4 GB is really something you'd need to spend money on. It might make a difference at 16xAA and the most stringent games, or if you game in 3D Stereo and triple monitor gaming -- I mean sure -- at any point graphics memory can and will run out. There's one exception to the rule, and that's Skyrim all beefed, tweaked and modded upwards. But the universal question remains, is it worth it investing in that extra memor? This card is 90 EUR more expensive. Well that answer depends on pricing versus your demands and requriements really, the extra memory certainly won't hurt that's for sure, but sure -- the benefits remains small
.







I remember in May last year I was hesitating between Quad 7970 or Quad GTX 680 4 GB Classified.

And the EVbot and 4GB was just to gimmicky to me so I end up with Quad 7970s.

K, I've read pretty much every review out there on the 4GB cards, including the one you linked wink.gif

I'm pretty sure that the one you're quoting is reviewing a single 4GB card. And I think there's a pretty broad consensus that the 4GB version has no benefit in a single card setup, esp not at sub-surround resolutions (save for maybe running a heavily texture-modded Skyrim, or the like).

And again, ttbomk, nowhere in that review does it 'back' the idea that 'the issue' with the 4GB card is the ratio of bandwidth to capacity. The problem is that the GPU itself doesn't have sufficient power ... either that, or the tests they've chosen simply are not 'using' enough memory for us to 'see the difference' between the 2GB and 4GB cards.

Yes it is.

I am trying to find a review that compare Tri-SLI GTX 680 2GB to 4GB and can't find any though.

Maybe no one did it yet.

This is very true. The problem I had when I had TRI-SLI 670's was the actual 2GB, not the power or the interface. People try & say it isn't a difference between 2 & 4GB when it actually is. Not talking about speed, but when you're gaming & you hit 0FPS. That's Vram limit. Nothing else.

To make the 4GB of VRAM on the GTX 670 work for you, you are going to need at least three of them for 3-way SLI, to give you the performance to back up the VRAM. Or, we would also like to see 4GB of VRAM on 2-way GTX 680 overclocked, or even 3-way GTX 680. There are advantages to more VRAM, and 4GB can smooth out performance in a lot of games, but today's games are more GPU demanding than ever. These newer games require a lot of performance, and GTX 670 is already starting to show its age in today's latest games. We are already experiencing today the fact that we need faster GPUs in games like Far Cry 3 and Hitman: Absolution.

OP, With the options you presented I'd go 4G 680's in Tri SLI.

To those that didn't bother to read about frame rating and call it voodoo, you make the case by saying it looks fine to you with your CF setup. some are not getting it. You are not getting that massive Full FPS you think you are.

It's like a Jedi Mind Trick, "Your TriFire is getting 120 FPS....thumb.gif


And we all (past tense) just believed it until somebody pulled back the covers and actually frame captured every frame coming out of the DVI / VGA port. runt Frames made of 5 to 20 or so scan lines counted as Full Frames. Oops

You cannot compare two different cards, you would have to compare a GTX 680 2 GB with a GTX 680 4GB. Not a GTX 670 2 GB with a GTX 680 4GB

(Would you compare a HD 7970 6GB to a HD 7950 3 GB? Its the same irrevelant comparaison)


Look at this, see what I mean, even the GTX 680 2GB is winning on the GTX 670 4GB.

So this totally means that your comparaison is irrevelant. rolleyes.gif
