So, the real world benefit to quad SLI is about 222% that of a normal 680.

A 690 is a bit less because you can't overclock and you're locked at about 10% under a 680 is most cases so, we multiply that 222% by 0.9 or (90%) to arrive at 199.8% or 200%.

So essentially, a 690 in Quad-Sli is already defeated by a 680 in Quad.

Now, the current claim is that a Titan is already 30% faster overall then a 680.

So, you do the same scaling for a Titan. but, include the fact that a Titan is 130% of a 680.

So let's use the same 222% but, include the percent of difference. (For Quad SLI and assume the same scaling)

In fact, all we really need to do is multiply 222% by 1.3 (130%) and we arrive at 288.6% the performance of a single 680.

Now if we were to do just Tri-Sli it comes out to about 221%.

Remember that Quad-SLI 680's were just 222% the performance of a 680 ~ Interesting, isn't it?

So realistically, even with scaling, Tri-SLI TITAN is equal to Quad 680s which are inherently better then 2 690's so...Yeah.

If anyone wants to check the math, take your performance scaling and the base performance increase of the Titan to the 680 and then do a statistical performance mock-up ~ It won't be perfect but, it will be close enough.

I never cared for dual-GPU single slot cards. Though, even way back in the 580's heyday in demanding scenarios SLI scaling could be quite good sometimes in my testing (3x 30" or 12 megapixel):

I don't get it, why is nvidia getting so expensive? The 680 launched at $500 and was barely slower than the gtx 590. Same case with the Titan and the 690.

this is probably the only card worthy of a H20 block in a long time but the price tag is pretty steep ,i passed on the first " kepler" due to luck of OC potential (MSI Lightning is the only 680 worth buying in my opinion)..........if this card will drop $100 in the next month i will pull the trigger ,but i would have hard time paying $1140 (H20 block+card) ,we are looking at about @ $2300 for SLI right now ..that just stupid for most

65FPS with Ultra 1200p 8xAA in Valley is pretty good I guess rolleyes.gif
65fps in Valley at Ultra 8xMSAA 1920x1080 (essentially Extreme HD Preset) seems very low.
Look at the scores from here: http://www.overclock.net/t/1360884/top-30-unigine-valley-benchmark-1-0/0_30
Most overclocked 680s and 7970s reach about 50 fps average at those same settings...

Extreme HD is 1080p. That Titan got 65FPS on 1200p thumb.gif
Anyway, it was just a brief moment we saw Titan hit 65FPS and 1200MHz in the video. He didn`t benchmark it, just show us how the GPU boost works

You are the one trolling pal.

I had GTX 690 4-Way SLI in my ASUS P8P67 WS build with a 2700k at 5.1ghz. I have GTX 680 3-Way SLI in my ASUS X79 Sabertooth with a 3930k at 5ghz and have one of the GTX 690s from that previous build in another identical X79 Sabertooth build.

4-Way SLI does not scale as well as 3-Way SLI. It is faster though but isn't perfect or worth the price you pay for it. 3-Way is the sweet spot and in previous generations actually smoothed out and helped micro stutter in SLI and Crossfire systems. It did in my HD 6990 + HD 6970 system for sure. There were some reviews on it which actually confirmed it too.

Don't agree with the X79 micro stutter statement at all. That's a bunch of rubbish. Maybe in cheaper board designs but not in quality ASUS boards. I've had up to 4-Way SLI and crossfire in my current build and never experienced any microstutter with my final set-ups. I have experienced it with radeonpro pro and trying different settings with my Lightning set-up, but they were merely tests and radeonpro pro in the end actually reduces and eliminates microstutter with the right settings. So thats rubbish. Maybe people are getting confused with hitting VRAM limits, maybe something else is causing it but most probably they don't know what they are doing.

Microstutter was rampant last generation in the AMD line-up and in the GTX 590. AMD had some with the HD 7970 when it first are out but since has been fixed and radeonpro pro had it fixed for some time also. AMD cards are now smooth and the performance is shockingly good as we all know. They really turned stuff around since last generation which were a mess.

So no. Everyone screaming microstutter as a way to justify a Titan is misinformed. GTX 690s of all cards have built in preventative measures for this and the cards do not Exhibit from any noticeable microstutter. I've had two, have only one now and had since launch and it's an amazing card in that regard. The powercolor HD 7990 doesn't have any microstutter either. Had a Devil for a short while and it was a premium piece of equipment.

As for the rest of what he said Titan SLI overclocked will beat 3-Way GTX 680 and 3-Way Titan SLI reference will beat 4-Way GTX 680 at 1600P and above (as for 1080P, Lol, who cares). Even if it's only 30% faster. SLI doesn't always scale 100% when getting over two cards so it doesn't have a huge task ahead of it and with everything we've seen so far the Titan despite our worst fears seems like it will be a very fast card. Not faster than a GTX 690 at reference speeds but that was far too optimistic an assumption anyways. Maybe in some cases it could but overall I would doubt it and it definatly will not be worth the $1200-1600 price tag they put on them over here.
