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

NVIDIA GeForce GTX Titan X 12GB in SLI - Two is Much Better Than One
NVIDIA blew us away with the GeForce GTX Titan X, but they are about to do it again with SLI goodness. Two GM200 GPUs in a single system is simply superb.

When I started writing my GeForce GTX Titan X review, I was packing my bags to prepare for NVIDIA's GPU Technology Conference in San Jose, California - but now I'm back from GTC 2015 with another Titan X in hand, and we're about to get some GM200 in SLI results that are sure to impress.




During GTC 2015, NVIDIA officially announced the GeForce GTX Titan X, which is powered by the full GM200 core. We went through this in our original review of the Titan X, where we have a super powerful video card that impressed us in every resolution possible. We even tested it with NVIDIA's 4K Surround, where we used three 4K monitors for a huge 6480x3840 resolution, thanks to Acer's XB280HK displays.


Even still, the Titan X was able to provide a playable 30FPS or so frame rate, but we're excited to see what two Titan X cards can do in 4K Surround. First, we'll see how they do in our usual tests, with 1080p, 1440p and 4K.




Titan X samples are hard to come by, so we're quite excited to have two of them in the TweakTown labs. We have a third one on its way, and a fourth is something we're going to be working on. It's still pretty unbelievable that we have this type of power right now on 28nm technology - incredible fast, but very efficient video cards with the possibilities really opening up with 4-way SLI and 4K and beyond.


NVIDIA were very kind to provide us with a second GTX Titan X, so we immediately began testing the Titan X in SLI as soon as I landed back from my GTC 2015 trip. It was quite an amazing sight, seeing two Titan X cards in SLI.



Testing Method


Because I'm just starting out reviewing GPUs, we're going to slowly evolve our benchmarking setup. I'm not going to dive into the deep end and start testing out real-time FPS, as this will hurt the quality of the reviews. Instead, I'd like to nail these initial reviews and then we can start doing real-time numbers of games like Far Cry 4, and Star Citizen. For now, I've played Battlefield 4 on a 64-player server to provide some real-world performance numbers.




For now, I'm going to be using the same suite of benchmarks I've been using on my Tweakipedia articles, which uses a mix of synthetic benchmarks with Futuremark's 3DMark and Unigine Heaven. After that, we have a bunch of titles with built-in benchmarks (which does not represent actual in-game performance) but they are repeatable for you at home to gauge the performance of your PC or GPU.


Over time, I will be adding in new benchmarks and a new section that will concentrate solely on real-time gaming benchmarks. This will take more time per review, as I'll have to invest time into actually physically playing the games, but it'll be worth it in the long run. For now, let's get right into the synthetic benchmarks and see how this NVIDIA GeForce GTX Titan X performs in SLI.



Test System Configuration


We only recently built our new X99-powered system, something you can read about here. As for the detailed specifications, this is what we're running:




  • CPU: Intel Core i7 5820K processor w/Corsair H110 cooler
  • Motherboard: GIGABYTE X99 Gaming G1 Wi-Fi
  • RAM: 16GB Corsair Vengeance 2666MHz DDR4
  • Storage: 240GB SanDisk Extreme II and 480GB SanDisk Extreme II
  • Chassis: Lian Li T60 Pit Stop
  • PSU: Corsair AX1200i digital PSU
  • Software: Windows 7 Ultimate x64
  • Drivers: 347.88




We're running the system at stock CPU speeds, which will provide more of a 'real-world' feel to our benchmarks. Sure, this isn't an i7-5960X at 5GHz, but what person is going to team up an incredibly expensive CPU with a mid-range GPU? Not many.


Our GPU tests are changing, shifting toward more of a real-world feel. But don't worry, we will be doing some crazy balls-to-the-wall tests that will see serious overclocks, Extreme Edition processors, and much more in the coming months. For the most part, we will be doing more real-world testing by teaming up the right processor with the right GPU in its price category.
