Intro

The GeForce GTX 1070 is the second GPU based on Nvidia’s Pascal architecture. It is very similar to the GTX 1080 that we reviewed last week although it is less powerful. It is also considerably less expensive compared with the GTX 1080 which launched at $699 for the reference Founder’s Edition, or at $599 for entry-level partner cards. The GTX 1070 is expected to be priced at $379, or at $459 for the built by Nvidia reference Founder’s Edition that we are testing today, and it will be available for purchase on June 10.

Instead of repeating all of the same information in our GTX 1080 launch review, we are going to highlight the differences between the GTX 1070 and the GTX 1080, and then we will benchmark it against a similar but updated benching suite to see just how capable it is.

Since the GTX 1070 is based on the same GP104 GPU used in the GeForce GTX 1080, the GeForce GTX 1070 supports all of the same new features that NVIDIA’s Pascal architecture brings. They both deliver high clock speeds while using relatively little power – the GeForce GTX 1070 runs over 1.6 GHz with a TDP of just 150 watts. Pascal’s 16nm manufacturing process allows the GTX 1070 GPU to perform faster than prior generation GPUs giving GeForce GTX 1070 a Nvidia-claimed 70% performance lead over the Maxwell generation GeForce GTX 970 which we shall test today.

BabelTechReviews was at Nvidia’s GTX 1080 Austin Launch event earlier this month, May 5-8. Nvidia’s CEO Jensen had just fully unveiled the new DX12, fully VR-enabled, 7.1 billion transistor Pascal flagship GTX 1080 and he also mentioned the GTX 1070. Nvidia has claimed that the GTX 1080 would be significantly faster than any other single GPU video card while the GTX 1070 would be about as fast as the TITAN X. Today we will give our own testing results of the GTX 1070 and its comparison with the GTX 1080 and the other top cards.

BTR received a GTX 1070 from Nvidia only this past Friday, and for the past two days we have put it through its stock and even some preliminary overclocked paces with our updated 25-game PC benchmark suite against the GTX 1080, the GTX TITAN X and GTX 980 SLI, and also versus the Fury X, AMD’s flagship. We have fully updated all AMD cards (Fury X/290X/280X) to their latest Crimson Software drivers, and we have added a GTX 970 EXOC and a GTX 980 for a further comparison, with all GeForce cards updated to their latest drivers released this last Monday, so our test bed is completely up to date and all of our games have been patched to their latest versions as of this morning.

We are testing all of our competing cards on a clean installation of Windows 10 64-bit Home edition, using resolutions of 1920×1080, 2560×1440 and at 4K’s 3840×2160. As befits testing top video cards, we use Intel’s enthusiast Z97 platform with Core i7 4790K turboed to 4.4GHz by the BIOS, and 16GB of Kingston’s 2133MHz Predator DDR3.

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. Since we benchmark 25 games, we have a much larger benchmark suite than any other English-speaking tech site in the world, so we are going to concentrate on performance and we will only briefly summarize the new features of the GTX 1070 and will go into further detail in future articles. But first, let’s bring our readers up to date.

The GTX 980 and the GTX 970 both launched in September 2014 as Maxwell GM204 architecture – a mid-sized chip – and both of them were faster than AMD’s flagship at the time, the R9 290X. Afterward, Nvidia launched their $1000 TITAN X as GM110, a big chip Maxwell GPU with 12GB of vRAM followed quickly by their 6GB-equipped flagship gaming card, the GTX 980 Ti for $649 which is slightly faster than the TITAN X in most games. In the meantime, AMD rebadged their 200 series lineup into 300 series, renaming the 290X into the 390X and equipping it with 8GB of slightly faster vRAM. AMD also brought out their new Fiji Flagship, the Fury X at the same $650 price point as the GTX 980 Ti, but its performance generally fell short of the GeForce card.

Key Features of the Pascal GTX 1070

Pascal offers large increases in performance, memory bandwidth, and power efficiency over the current Maxwell architecture. It introduces new graphics features and technologies that confirm the PC as the ultimate platform for playing AAA games and for enjoying virtual reality. All of the features found in the GTX 1080 are also present in the GTX 1070 and we would highly recommend looking back at our GTX 1080 launch article. However, this is a very brief summary:

Nvidia sums up Pascal’s features as being “the Perfect 10”, this being the GeForce ten series beginning with the release of the GTX 1080, and now, the GTX 1070.

Nvidia has engineered the Pascal architecture to handle the demanding computing and gaming needs of technologies like VR. It incorporates five new technologies:

Next-Gen GPU Architecture. Pascal is optimized for performance per watt. The GTX 1080/1070 are about 3x more power efficient than the Maxwell Architecture.

16nm FinFET Process. The GTX 1080 and the GTX 1070 are the first gaming GPUs designed for the 16nm FinFET process, which uses smaller, faster transistors that can be packed together more densely. Their 7.2 billion transistors deliver a significant increase in performance and efficiency.

Advanced Memory. Pascal-based GTX 1080 GPUs are the first to use 8GB of Micron’s GDDR5X memory while the GTX 1070 uses 8GB of the fastest available GDDR5 memory.

Superb Craftsmanship. Increases in bandwidth and power efficiency allow the GTX 1080 and the GTX 1070 to run at really high clock speeds while only using 180 watts and 150 watts of power respectively. New to Pascal is asynchronous compute. And new GPU Boost 3 technology supports advanced overclocking functions.

Groundbreaking Gaming Technology. New VRWorks software features let game developers bring more immersion to gaming environments. And Nvidia’s Ansel technology lets gamers share their gaming experiences and explore gaming worlds in new ways.

The next generation of games will not only look better but run faster on the GeForce GTX 1080 and the GTX 1070. Nvidia has developed a number of advancements for virtual reality – reducing latency, improving image quality, and bringing a whole range of new content to VR.

The GTX 1080 Pascal GPU

First, take a look at the GTX 1080 block diagram which proved to be the world’s fastest GPU as we have shown.

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 Micron’s 256-bit GDDR5X at 10 Gbps which makes it 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).

The GTX 1070 has 3 Graphics processing clusters and it uses 15 Streaming Multiprocessors and 1920 CUDA Cores. The GeForce GTX 1070 runs at a Boost Clock Speed of 1683MHz. Its 120 Texture Units provide a peak texture fill rate of nearly 202 Gigatexels/sec. The memory subsystem of the GeForce GTX 1070 features a fully enabled 256bit memory interface, and ships with 8 Gbps of fast GDDR5 memory, providing up to 256 GB/sec of peak memory bandwidth, but not up to the speeds of the GTX 1080’s GDDR5X. We also managed more than a 200MHz offset to our sample of the GTX 1070’s core with the new Precision XOC and a surprising +500MHz offset to the GDDR5 memory to 4500MHz.

As befits a new architecture, Pascal uses a more advanced and efficient memory compression system. More effective memory compression means a significant savings in bandwidth which make for more efficiency and for faster video cards than Maxwell.

The Founder’s Edition of the GTX 1070

The GeForce GTX 1070 Founders Edition, like the GTX 1080 Founder’s Edition, are reference graphics card designed and built by Nvidia. The GTX 1070 Founder’s Edition will sell for $459, $80 more than the base models of the GTX 1070 partner cards. It was crafted with premium materials and components, including a die cast aluminum body and a low profile backplate. It is ideal for situations where air needs to be exhausted out of a case, and perfect for SLI compared with open designs which do not do well in small form factor cases.

Underneath the GeForce GTX 1070’s metal shroud lies an aluminum heatsink. Embedded in the base of the heatsink are three copper heatpipes which are responsible for drawing heat off the GPU. Heat from the heatpipes is then dissipated by the aluminum heatsink. Finally, a metal baseplate is placed on top of low profile components, providing clean air channels for the thermal efficiency and quiet cooling.

The GTX 1070 comes in a big and rather heavy box. If you remove the top of the box, it makes a nice display for the card.

The Founders Edition of the GTX 1080 and the GTX 1070 are premium built by Nvidia reference versions that will be available for purchase for the entire life of the Pascal line instead of only at launch.

Specifications

Here are the specifications for the GTX 1080:

Now let’s look at the specifications for the GTX 1070:

The connectors for the GTX 1070 are identical to the GTX 1080’s:

How does the GTX 1070 compare with the GTX 1080 and with their rival, AMD’s Fury X?

First of all, as we saw in our GTX 1080 launch article, the GTX 1080 is simply in a class above the Fury X and even well above GTX 980 SLI, GTX 980 Ti and above the TITAN X. However, the GTX 1070 is slower than the GTX 1080, and in a very few games it trades blows with the Fury X, in most others, it is much faster We are going to look at the performance of 25 games to compare the GTX 1070 with the GTX 1080, with the TITAN X, with the GTX 980 Ti and with the GTX 980 SLI, and versus the Fury X. And of course, we want to see how much the GTX 1070 has progressed over the Maxwell GTX 970 by comparing with the mildly factory overclocked GALAX GTX 970 EXOC.

However, before we do performance testing, let’s take a closer look at the GTX 1080 and check out overclocking and noise.
