NVIDIA GeForce GTX Titan X 12GB in SLI - Two is Much Better Than One

By: Anthony Garreffa | NVIDIA SLI Articles in Video Cards | Posted: Mar 28, 2015 7:05 am

Titan X Times Two = Wow.

 

As you're about to see below, two GM200-powered GeForce GTX Titan X cards in SLI is something that truly needs to be seen, in order to be believed. We have some absolutely mammoth performance and some great SLI scaling between these cards.

 

Performance at 1080p

 

No one is going to buy two Titan X cards and throw them into SLI at 1080p, and as you can see from our Battlefield 4 results, we're maxing out the capabilities of the Frostbite engine itself with a huge 175FPS average on the Medium preset. Turning it up to Ultra, we think premature drivers are seeing a reduction in performance with the cards in SLI - with 13FPS less average performance than the single Titan X.

 

GRID: Autosport has hit a wall at 160FPS, so the Titan X SLI set up doesn't offer anything at 1080p. But, we're also running $2000 worth of VGA cards at 1080p, which is not the typical scenario. But in saying that, Metro: Last Light has some great scaling with the Titan X in SLI, where we shift up with those minimum frame rates from 7FPS to 24FPS, which is huge. The average FPS also jumps up from 100FPS on the single Titan X to 141FPS on the Titan X in SLI - an improvement of 41%.

Tomb Raider has some massive scaling with the second Titan X, leaping from 138FPS to 235FPS, representing a huge 70% increase in performance. The minimum FPS was also increased by a huge 68%, increasing from 104FPS on the single Titan X to 175FPS minimum on the SLI'd Titan X cards.

 

Performance at 1440p

 

We are getting some huge limitation with the Frostbite engine in Battlefield 4 with the two GeForce GTX Titan X's in SLI, where at 1440p and the Medium preset, we're achieving a huge 144FPS minimum and 183FPS average - On the Ultra preset, we see a huge 120FPS minimum and 166FPS average.

 

We hit the 160FPS wall on GRID: Autosport, even at 1440p with our Titan X's in SLI. Metro: Last Light lathers up the SLI goodness, with a huge 53% performance improvement over the single Titan X with an average of 101FPS, versus the 66FPS on the single Titan X.

 

Shadow of Mordor has a decent increase of 26% at 1440p, while Thief enjoys a nice 49% improvement thanks to the second GeForce GTX Titan X. Tomb Raider scaling continues its kicking ass from 1080p to 1440p, with an improvement of 71% - increasing from 92FPS average at 1440p, to 158FPS.

 

Performance at 4K

 

Amazing performance with the Titan X SLI and Battlefield 4 at 4K, where on the Medium preset we have a huge 138FPS average, beating out the GTX 980 SLI and its 128FPS average. Comparing it to the single Titan X, the Titan X's in SLI are 53% faster for average FPS. The difference between the single Titan X and Titan X's in SLI was also beneficial for the minimum frame rate, which leaps from 64FPS to 86FPS, or 34%.

On our Ultra preset (minus AA) the Titan X SLI is our new star: 119FPS average, a massive 63% improvement on our single Titan X score, and 26% faster than our two GTX 980s in SLI. We're seeing the 384-bit memory bus come into play here, which is great to see. 119FPS average at 4K with Ultra settings is just amazing performance - bring on those 4K 120Hz panels, I say.

 

This is what we're here for, right? Starting with GRID: Autosport, we're not near the 160FPS wall that we experienced with 1080p and 1440p, but the performance benefit of the second Titan X is apparent. We see an increase of 28%, from the 95FPS on the single Titan X, to the 122FPS on the Titan X SLI.

 

Metro: Last Light enjoys a 26% increase in performance from the second GM200-powered GPU, while Shadow of Mordor excels with a huge 54% increase in performance thanks to the Titan X SLI. We see Thief with a huge 68% increase in average FPS, while Tomb Raider leaps by 56%.
