Re:GTX 690 in Quad-SLI Surround Review: 5760x1080

To me that is evidence of a CPU bottleneck since addition GPU's don't appear to do much, but I don't know if those with a pair of dual-GPU cards are willing to wait out for a next gen architecture and overclock it just to regain their 4-way scaling.
Afterall, the average Core 2's overclocked 3.6-3.8GHz couldn't properly handle a pair of 9800Gx2, but the equivalent nowadays is a single GTX470 and an Core i7 handles that just fine. So while the scaling of 4-way Keplers doesn't look that impressive, the bottleneck is Sandy Bridge since it cannot be practically overclocked high enough 24/7.

Hi Lephron  Even with a 3930k @ 4.6? That's what they are using.

At one point in the past 5GHz Pentium D was beaten by a stock Core 2 Duo at 3GHz, which nowadays is like a Sandy Bridge down at 2.2GHz or so. Frequency is relative and something new will always show up and upstage everything we have; and relieving any CPU bottleneck we may have where overclocking wasn't good enough-- but most folks who buy the best don't typically keep their stuff long enough to see how 4-way can scale.
A Haswell-E overclocked may improve Quad-SLI GTX690 scaling, so will the next architecture, but by then you may have moved on.

Is it possible that the scaling or lack thereof is related to low memory? The graphs do not show memory usage, but with that kind of juice from cpu and what I assume (correct me if I'm wrong) to be quad SLI, then 2gb of RAM might be limiting with a resolution of 5760x1080. This I think is more evident in games like BF3 and Batman that chew up RAM.

The commercial is top notch, too. The blonde is a hostess on G4's Attack Of The Show, and a Playboy Playmate.

It doesn't look like memory is an issue, though. Look at the fps.

That's exactly what I'm looking at. When BF3 in ultra settings goes from 41.9fps on a single 690 (2 GPUs) to 46.7fps on SLI 690 (4 GPUs). That's about a 10% increase in frames with 2 additional GPUs. The memory would be the biggest suspect. Like I said previously, they didn't record memory usage with this benchmark so it's hard to tell, but I suspect that's the culprit. It would be interesting to see the results with quad SLI of 4gb 680s to compare to this.

Looks to me that they were using a 4.6Ghz 3930K, and that mobo is PCI 3.0 ready, but im willing to bet that it was running 2.0. No way to tell if it was running both slots at 16x PCI 2.0 or not. And on top of that, that board they used says its rated for Nvidia 3-way SLI, not quad SLI, so it may not have even been using all 4 gpus correctly. To back that assumption up, the power draw on the single 690 during gaming was 456 Watts, and the power draw on sli 690 was 649. Which means that the second 690 only added 193 watts. It pulls closer to 250-260 watts not overclocked on full load. Mine with the OC i have is running 280-300 watts.

Doesn't look like it scales too well.

I wish someone would post a real review of these two cards using a single 2650 X 1600. I here that a lot of games are hampered by the quad set up like BF3 and others? Is this true? I trying to Figure if I should go 3 way 680 classy's or a couple of 690>

680 classy's does not have EVBot anymore.... so 3x680 FTW 4GB I think will beat 2x690!

2x690s would beat 3 x 680s

Speak to Delirious he's running quad sli gtx690 and I believe he's running 2560 x 1600, and he's experiencing butter smooth fps from when I had spoken to him. I'm personally running 2560x1440 and in BF3 with all max settings. I'm averaging 70-90+ and get up to 120+, too. The lowest I've seen it hit is the high 40s-50s, from what I remember. As for my vram, I've seen it hit above 1900, but never past 2gb. You also gotta rememer that these 600 series cards will only use the vram you have and stay typically under it; now I'm only speaking based on a single monitor setup. Now from the link I showed in the orginal post above, the fps are still high for a surround setup. I dont think the dips or small increase in fps in quad-sli is due to vram; it's due to the 690 not scaling right due to drivers not being mature yet. I believe Nvidia has only released 2 maybe 3 WHQL drivers? Again, this is from a "brotha" using 2x690s .

at my resolution (8080x1440) Any of the new games, I can max out all settings with the exception of any kind of AA (FXAA is enabled). I have to turn of Windows aero (I also have a 1920x1080 4th monitor and with aero off at the desktop it only uses about 150MB vram.) I average 30FPS with the 1 690. I imagine that quad SLI at this resolution would push out at least 45 FPS, but at this resolution, VRAM is heavily taxed. $2000 is too much to spend on video cards to only have 2GB of ram at my resolution. I am running this setup for s specific reason, mini-itx and all that so i needed 1 awesome card.
If i was running a full size gaming rig, I would be hands down running Tri SLI 4GB cards instead.
5760x1080 is a whole different story. It uses a ton less VRAM than 7680x1440.1600. 2GB is much more reasonable on 5760x1080. But for 7680x1440/1600, you want no less than 3GB. On the new 4K monitors that will come out we are probably going to start seeing the need for closer to 8GB vram on the surround setups.
On 1 monitor, any resolution, 2GB vram on a 690 is fine for anything out today.

Sup crezno! What is the max vram you're using at that rez? That's some hardcore surround there! I'm starting to think that aero is all flash. I'm just starting not to use it.

Im always over 1800MB VRAM and thats usually with all VRAM off. If I even do AAx2 it will not allow me to load a game, or it will crash it. In MWO, BF3, etc... with High Settings and AA off, its usually above 1900MB with Aero Off. With Aero on I get huge framerate decreases to a point its almost unplayable. But at my resolution, Aero uses right around 550MB VRAM.
