The GeForce GTX 1070 Ti is NVIDIA’s latest Pascal GPU that we review today and benchmark with 35 games.  It is similar to the GTX 1070 although it is more powerful and closer to the GTX 1080 in performance.  This new $449 GTX 1070 Ti is more expensive than the $379 GTX 1070, but it is also less expensive compared with the GTX 1080 which can be found for around $500 bundled with Destiny 2.  The GTX 1070 Ti will compete directly with AMD’s reference RX Vega 56 which is supposed to retail for around $399.

Instead of repeating the same information from our GTX 1080 and GTX 1070 launch reviews, we will highlight the differences between them and the GTX 1070 Ti, and then we will benchmark it using our 35-game benching suite to see just how capable it is.  We are going to compare its performance with the GTX 1080 and the GTX 1070, and we will see how close it can get to the RX Vega 64 Liquid Cooled Edition which retails for $699.  We are still waiting on aftermarket custom RX Vega 56 designs as they are not yet available, nor can we flash the BIOS of an air-cooled Vega 56 onto our liquid cooled Vega 64.  

The GTX 1070 Ti is based on the same GP104 GPU used in the GeForce GTX 1080.  It supports all of the same features that NVIDIA’s Pascal architecture brings.  Pascal delivers high clock speeds while using relatively little power – the GeForce GTX 1070 Ti runs over 1.6 GHz with a TDP of under 200 watts.  With the arrival of the GeForce GTX 1070 Ti, NVIDIA’s GeForce GTX lineup consists of the following GPUs:

  • GeForce GTX 1080 Ti
    GeForce GTX 1080
    GeForce GTX 1070 Ti
    GeForce GTX 1070
    GeForce GTX 1060 6GB
    GeForce GTX 1060 3GB
    GeForce GTX 1050 Ti
    GeForce GTX 1050

NVIDIA claims that the GTX 1070 Ti is also supposed to be an excellent overclocker, and we will let you know if we are able to reach 2GHz or not.  If so, an overclocked GTX 1070 Ti should be able to match stock GTX 1080 performance which would overall make it faster than a RX Vega 64 in our benches.

BTR received a GTX 1070 Ti Founders Edition from NVIDIA, and for the past week we have put it through its stock and even some preliminary overclocked paces with our updated 35-game PC benchmark suite.  Our testing platform is Windows 10 Home 64-bit, using an Intel Core i7-8700K which turbos to 4.6GHz for all cores as set in the ASRock Z370 motherboard’s BIOS, and 16GB of HyperX DDR4 at 3333MHz. The settings and hardware are identical except for the video cards being tested.

We are also featuring our newest 2017 games including Destiny 2, Middle Earth: Shadow of War, Assassin’s Creed Origins, and also Wolfenstein: The New Order on the Vulkan API.  We will compare the performance of 35 modern games at 1920×1080, 2560×1440, and at 3840×2160 resolutions with maximum settings.

Specifications and Features of the GTX 1070 Ti

Before we give you the results of our performance testing, we want to briefly cover Pascal architecture, as well as detail the specifications and features of the new GTX 1070 Ti.  Since we have a larger benchmark suite than any other English-speaking tech site in the world, we are going to concentrate on performance and we will only briefly summarize the new features and specifications of the GTX 1070 Ti.

Pascal GP104

Here is the GTX 1080 block diagram.Pascal GPU

The GTX 1080 GPU has all 4 Graphics Processing clusters enabled with 64 Raster Operating Units, 20 SMs of 128 Cores each totaling 2560 CUDA cores, 20 Geometry units and 160 Texture units.  It uses GDDR5X at 10 Gbps on a 256-bit memory interface which means it is significantly faster than GDDR5, and its 1.61GHz GPU clock has a boost of 1.73GHz or higher.   We also easily managed better than a 1.9 GHz boost clock with complete stability and an offset of +400MHz to its GDDR5X memory (5400MHz).

As befits the slower GTX 1070, it has 3 Graphics processing clusters (one of the GTX 1080’s GPCs are disabled), and it uses 15 Streaming Multiprocessors, 120 Texture Units, and 1920 CUDA Cores. The GeForce GTX 1070 runs at a Boost clock of 1683MHz. The memory subsystem features a 256bit memory interface, and ships with 8 Gbps of GDDR5 memory. We also managed more than a 200MHz offset to our sample of the GTX 1070’s core and a + 500MHz offset to the GDDR5 memory to 4500MHz.

The GeForce GTX 1070 Ti is built around the same GP104 GPU but with 19 Streaming Multiprocessors (SMs).  The GeForce GTX 1070 Ti features 2432 CUDA Cores and 152 Texture Units. Like the GeForce GTX 1070, the GTX 1070 Ti also runs with a Boost clock of 1683MHz and it has 8GB of GDDR5 memory operating at 8 Gbps featuring a 256-bit memory interface.  And as you will see, it also overclocks very well.


Here are the specifications for the GTX 1070 Ti:

The specifications for the GTX 1070 Ti are much closer to the GTX 1080 than to the GTX 1070.  The main differences between the GTX 1070 Ti and the GTX 1080 are that the new Ti has slower memory but retains most of the 1080’s CUDA cores and texture units.  

Like the other Pascal cards, the GTX 1070 Ti includes support for NVIDIA Simultaneous Multi-Projection (SMP) technology, which allows it to seamlessly project a single image simultaneously to both eyes, yielding a 3x VR graphics performance improvement over NVIDIA’s last generation GPUs. This allows GTX 1070 Ti users to play VR games with higher levels of detail with this tech enabled than similarly performing video cards without it. SMP has been integrated into the Unreal and Unity Engines, and more than 30 SMP-enabled VR games are already released or in development, including Batman Arkham VR, Elite Dangerous, and Eve Valkyrie.

The Founders Edition of the GTX 1070 Ti vs. Partner custom editions

The GeForce GTX 1070 Ti Founders Edition (FE), like the GTX 1080 FE and the GTX 1070 FE, are reference graphics card designed and built by NVIDIA.  The GTX 1070 Ti Founders Edition will sell for $449.  It is crafted with premium materials and components and it is ideal for SLI or for situations where air needs to be exhausted from a small form factor case.

Custom cards designed by NVIDIA’s partners will also be available today at launch. The partners have many custom-designed cards, including basic models, miniature cards, and those with special fans and cooling solutions.  We are unsure if they will differentiate their products on the basis of “factory overclocking” but there will be no confusion as to how the GTX 1070 Ti performs since the GTX 1080 is also an excellent overclocker.

How does the GTX 1070 Ti compare with the GTX 1080, the GTX 1070, and with AMD’s new RX Vega?

We are going to look at the performance of 35 games to compare the new $449 GTX 1070 Ti with the $499 GTX 1080, with the $379 GTX 1070, and also with the much higher-priced $699 RX Vega 64 Liquid-cooled edition.   Comparing with AMD’s top $700 liquid cooled card should be a very unfair comparison as the $450 GTX 1070 Ti is only intended to compete with the RX Vega 56 in a similar price range.  At stock clocks, the RX Vega 64 Liquid cooled edition is much faster than the reference Vega 56 which does not usually catch it even when it is overclocked.

However, before we do performance testing, let’s take a closer look at the GTX 1070 Ti
