NVIDIA GeForce GTX 1080 official slides has been leaked by Videocardz. So we continue with leaks of NVIDIA GeForce GTX 1080 and now its time to compile things as now we know the full specification of NVIDIA’s Pascal based high-end Graphics card. The NVIDIA Geforce GTX 1080 is powered by Pascal GP104-400 manufactured on 16nm FinFET with a die size of 314 mm2, which is composed of 7,200 million transistors where it hides 40 Streaming Multiprocessors leading to the 2560 CUDA Cores with 160 TMUs and 64 ROPs which gives a floating point performance 8.2 TFLOPS and can boost to higher clock speeds with the new GPU Boost 3.0 algorithms.

The reference GPU reaches a Base / Turbo frequency of 1607/1733 MHz coupled with 8 GB of GDDR5X memory @ 10.000 MHz with a memory interface of 256 bits gives a bandwidth  320 GB / s, all this leads to a TDP of 180W so you need a single PCI-Express 8 – pin connector to feed this beast.

8GB GDDR5X Memory

The NVIDIA GeForce GTX 1080 is the first graphics card to feature GDDR5X memory, which can significantly increase the bandwidth of the GPU, thanks to its 8 32-bit (256 bits total) memory controllers the bandwidth reaches 320 GB / s. This value is achieved with a reference design running @1250 MHz (10 GHz effective).


Understanding of Pascal memory:

With Pascal GP104 silicon a new memory compression technology debuts. Specifically, we are up to the 4th Generation known as “Delta Compression“, which promises to improve the bandwidth of the GPU, according to official slide it delivers up to 1.7x bandwidth conservation compared to Maxwell.

NVIDIA Fast Sync

The NVIDIA GeForce GTX 1080 also brings a new technology called Fast Sync, at the moment we don’t have much detail on it, but judging by the graphics, this new tech allows much faster rendering frames (30-40 milliseconds) compared to V- Sync (90-110 ms). It might be more oriented to the world of Virtual Reality for a better experience replacing the V-Sync.

GeForce GTX 1080 Performance 

During the presentation Jen-Hsun Huang (CEO of NVIDIA) said that, the GeForce GTX 1080 is faster than an SLI configuration of two GeForce GTX 980, well this is true but only under the best possible scenario and that is limited to the Virtual reality. In virtual reality GTX 1080 is 1.7 times faster than a GeForce GTX 980For actual gaming performance we are still waiting for reviews, but it is definitely not faster, at least not in all games.

NVIDIA GeForce GTX 1080 Preemption in VR – Pascal

NVIDIA has chosen to use Preemption for Async Compute, while AMD has opted to make use of some specialized units for executing asynchronous computing, so the cards are now on the table. NVIDIA slide shows that their GeForce 10 series cards will be using Async compute in broad amount of applications that include Physics, VR and post processing. Preemption in VR would provide improved latency, better speed and fully asynchronous time wrap in VR titles. NVIDIA is calling it the first Pixel-level graphics preemption, which will allow graphics resources to preempt command buffer, pixels and triangles.

Asynchronous Computing

All the information we found on the following post” The GeForce GTX 1080 will natively support Asynchronous Compute“.

We are witnessing the implementation of a new camera system in the game that allow us to freeze the game to enter a photo modein real time called Ansel. This software will be implemented in drivers and will take advantage of GPU acceleration to render a screenshot, but not as we are used to it will convert it into 3D 360-degree format so in future we can visualize it via reality glasses or using a smartphone with virtual reality cardboard.

NVIDIA has added the ability to perform a wide variety of settings, many as if we were using a Photoshop application. For more realism, there is also a Super Resolution mode to create a high quality image of no less than8 Gigapixel or increase up to 32 times the native resolution on which we are running the game, so it will bring greater realism when you will view it via Virtual Reality glasses. Unfortunately, it will only be active in games that support this technology. The first game to support this technology are following: The Division, The Witness, Lawbreakers, The Witcher 3, Paragon, No Man’s Sky and Unreal Tournament.

You can see some examples of NVIDIA Ansel in the following link.


NVIDIA VRWorks Audio

As its name suggests, we are facing an audio technology that will further enhance our experience with the use of virtual reality glasses. This sound technology is recreated in a 3D scene promising a pretty accurate acoustic. To do this, the waves of the sound source will be heard differently depending on the position of our head, waves interacting with 3D objects, so if we stand in front of an obstacle this sound will be weaker by blocking part of these waves while others will enhance the sound bouncing on that object.


NVIDIA VRWorks Graphics

The combination of VRWorks Audio technology with the implementation of NVIDIA PhysX, which resulted in a demo called NVIDIA VR Funhouse, which must be recognized that shown quite well. Far from what we’re used to seeing with our HTC Vive, this translates into a good graphic quality to what is added positional sound and the use of a PhysX that provide greater realism to confetti when they explode the balloons, the physics of liquids, or simply wigs “mini punching bags”, which complete the visual aspect.

Simultaneous Multi Projection

Finally a technology that was already implemented by Sony with its PlayStation 4 thinking about the PlayStation VR, unless a different name, we are talking about the Simultaneous Multi Projection (SMT). This technology is introduced with the GeForce GTX 1080 (we assume that it will be also compatible with the GTX 1070) and allows the GPU to create different views of the same scene (up to 16) with a minimal decrease in performance of the GPU.

Virtual reality is the next frontier where GPUs must show their mastery and offer two different points of view at the same time without incurring a performance penalty, so it was a great challenge. With this new technology, it seems that NVIDIA has eliminated this problem. As we said at the beginning with the PlayStation VR, this technology was running a character with a frame-rate around 60 FPS. Once it will be fully implemented this stereo filter will be able to reach the 90 FPS, allowing a higher return on VR titles and thus a greater sense of realism.


NVIDIA will officially release its new GeForce GTX 1080 and GeForce GTX 1070 on June 10, 2016.  The Founder Editon will go on sale for $699 US, while the non-reference models will be available for $599 US.
