We've already covered the features of Nvidia's GeForce GTX Titan, the $1,000 GK110-powered beast set to exist alongside GeForce GTX 690. Now it's time to benchmark the board in one-, two-, and three-way SLI. Is it better than four GK104s working together?
Two days ago, we gave you our first look at a beastly single-GPU graphics board in Nvidia GeForce GTX Titan 6 GB: GK110 On A Gaming Card. For some reason, the company wanted to split discussion of Titan’s specs and its performance across two days. That’s not the direction I would have gone (had I been asked for my opinion, that is). But after knocking out several thousand words on the first piece and benchmarking for a week straight in the background, cutting our coverage in half didn’t bother me as much.
If you missed the first piece, though, pop open a new tab and check it out; that story lays the foundation for the numbers you’re going to see today.
I’m not going to waste any time rehashing the background on GeForce GTX Titan. In short, we ended up with a trio of the GK110-based boards. One was peeled off to compare against GeForce GTX 690, 680, and Radeon HD 7970 GHz Edition. Then, we doubled- and tripled-up the Titans to see how they’d fare against GeForce GTX 690s in four-way SLI. Of course, compute was important to revisit, so I spent some time digging into that before measuring power consumption, noise, and temperatures.
Let’s jump right into the system we used for benchmarking, the tests we ran, and the way we’re reporting our results, since it differs from what you’ve seen us do in the past.

We ran into a snag right away when the Gigabyte X79S-UP5-WiFi motherboard we use as our test bench proved incompatible with Titan. Neither Nvidia nor Gigabyte was able to explain why the card wouldn’t output a video signal, though the system seemed to boot otherwise.
Switching out for Intel’s DX79SR solved the issue. So, we overclocked a Core i7-3970X to 4.5 GHz, dropped in 32 GB of DDR3-1600 from G.Skill, and installed all of our apps on a 256 GB Crucial m4 to avoid bottlenecks in every possible way.
One thing to keep in mind about GPU Boost 2.0: because the technology is now temperature-based, it's even more sensitive to environmental influence. We monitored the feature's behavior across a number of games and, left untouched, core clock rates tended to stick around 993 MHz. A higher allowable thermal ceiling easily allowed them to approach 1.1 GHz. As you might imagine, the difference between benchmarks run on a cold GPU, peaking at 1.1 GHz, and a hot chip in a warm room can vary significantly. We made sure to maintain a constant 23 degrees Celsius in our lab, only recording benchmark results after a warm-up run.

Using one Dell 3007WFP and three Dell U2410 displays, we were able to benchmark our suite at 1920x1080, 2560x1600, and 5760x1200.
In the past, we would have presented a number of average frame rates for each game, at different resolutions, with and without anti-aliasing. Average FPS remains a good measurement to present, particularly for the ease with which it conveys relative performance. But we know there is plenty of valuable information missing still.
Last week, Don introduced a three-part approach to breaking down graphics performance in Gaming Shoot-Out: 18 CPUs And APUs Under $200, Benchmarked. The first component involves average frame rate, so our old analysis is covered. Second, we have frame rate over time, plotted as a line graph. This shows you how high and low the frame rate goes during our benchmark run. It also illustrates how long a given configuration spends in comfortable (or unplayable) territory. The third chart measures the lag between consecutive frames. When this number is high, even if your average frame rate is solid, you’re more likely to “feel” jittery gameplay. So, we’re calculating the average time difference, the 75th percentile (the longest lag between consecutive frames 75 percent of the time), and the 95th percentile.
All three charts complement each other, conveying the number of frames each card is able to output each second, and how consistently those frames show up. The good news is that we think this combination of data tells a compelling story. Unfortunately, instead of one chart for every resolution we test in a game, we now have three charts per resolution per game, which is a lot to wade through. As we move through today’s story, we’ll do our best to explain what all of the information means.
