Nvidia GTX 1070 SLI vs Titan X Pascal – 22 Games Tested Plus Synthetic Benchmarks

The GeForce GTX 1070 is the second graphics card based on Nvidia’s latest Pascal architecture following the powerful GTX 1080. It is a great card that delivers a significant performance increase over the last-gen products at a reasonable price point. In this post, we take a look at how two of these cards in SLI stack up against the the fastest GPU on the planet, the Titan X Pascal. Can the GTX 1070 SLI reach the performance level of the Titan X? Let’s find out.

Nvidia GTX 1070 SLI vs Titan X Pascal Performance Comparison

Based on the 16nm FinFET Pascal architecture, Nvidia Titan X is the fastest consumer GPU available on the market right now. It is around 60% faster than the last-gen GTX Titan X Maxwell and 20-30% faster than the latest GTX 1080. The card features 11 TFLOPs of FP32 and 44 TOPs of INT8 making it well-suited for neural networks and machine learning.


But, with great performance comes a premium price tag. The Titan X Pascal is priced at a whopping $1200 which is $350 more expensive than spending approximately $850 on the GeForce GTX 1070 SLI. This includes cost of two GTX 1070s at around $400 each plus $40 for an HB SLI bridge.

In terms of performance, the Titan X is around 25-40% faster than a single GTX 1070 so it should be interesting to see how this graphics beast fares against two 1070 cards in SLI where the latter is the “value” solution.

That being said, it’s worth mentioning that a single powerful GPU generally has advantages over SLI solutions; it’s often perceived as “smoother,” and the user never has to worry about deviation from ideal scaling that could deteriorate the expected results.

The GTX 1070 SLI versus Titan X benchmarks come from our friend Elric over at Tech of Tomorrow. Elric tested 22 games however, some DirectX 12 games were tested in DirectX 11 and that’s because they didn’t show any type of scaling at all in the latest graphics API.

There you have it. As you can see above when SLI scales well, it delivers a solid performance and even beats the Pascal version of the Titan X in many games. And it’s clear from the benchmark results that the GTX 1070 SLI scales very well. Obviously, not every game out there is going to scale and that’s one of the things why they recommended to buy the absolute best card that you can if you have the money.

The DirectX 12 games appear to have more issues with multi-GPU scaling than those on DX11; the only title where DX12 is faster is Ashes of the Singularity. That’s because not everything in DX12 has caught up so we’re not seeing great scaling across the board with that yet. But, as drivers change in DX12 matures, we can expect to see much better results in SLI all the way across the board.


So the question is, which graphics solution is suitable for you? Is it the $1200 Titan X Pascal or the $850 GTX 1070 SLI? Well the Titan X did perform extraordinarily versus two upper-midrange GPUs. The card is certainly expensive but it’s ideal for 4K and possibly the only consumer video card that could handle maxed out settings at that extreme resolution. The GTX 1070 SLI offers a similar level of performance but power usage and noise will be higher with it compared to the Titan X(P).

In short, if you want the fastest single GPU available today so that you could play the very latest games as soon as they are released, the Titan X may be the best choice for you. But not everyone can afford to splash out $1200 for a graphics card. In that case if you don’t mind waiting for an SLI profile then the GTX 1070 SLI is the way to go for you.

    Single Titan X Pascal wins hands down every time. Why? No SLI microstutter, scaling issues (especially with native DX12 games), and just plain better and smoother gameplay. Also, less power required and quieter operation. And I still prefer the Titan X Pascal over GTX1080 SLI for the exact same reasons. Yes, I could have easily afforded GTX1080 SLI, but know better that SLI has way to many issues now in the long run.

    For most AAA games sli is close to perfect with no micro stutter. Not all though

    “But, as drivers change in DX12 matures, we can expect to see much better results in SLI all the way across the board.”

    This is absolutely not true. DX12 is the opposite of DX11, where you see most of your performance gains due to driver optimization. The onus of responsibility and work to improve and optimize performance in DX12 titles is on the game/application developers, not on hardware manufacturers. However, due to Nvidia not offering true hardware support for asynchronous compute, amongst other low level API features that improve performance and reduce driver overhead, driver workarounds must be developed to optimize and improve performance.

      You really don’t know what you are talking about. Most DX12 and Vulkan support for multi-GPU will end up being Split Frame Rendering (all GPU’s work on the same frame). We need the game engine to improve, and then the game devs can do a better job of that.

      Driver support is still there, but this feature is primarily in the game itself.

      And NVidia isn’t “not offering” support for DX12 with asynch compute. Most of the focus has been optimizing by AMD for their specific Asynchronous Compute architecture which NVidia doesn’t even have in their GPU’s so they can’t easily create drivers for this.

      NVidia Pascal has something similar with Dynamic Load Balancing.

      Also, we’re still seeing gains comparing DX11 to DX12 that sometimes look even better for AMD because their DX11 performance is subpar.
