The DirectCU III cooler design from ASUS uses copper heatpipes in direct contact with the GPU. Atop the copper heatpipes are situated aluminium-finned heat sinks that are specially designed to direct heat away from the GPU with the help of three further fans. If the GPU is not under heavy load, e.g. 2D applications, and remains below the temperature threshold, the cooling fans can be slowed down or stopped completely when temperatures allow. This enables the quietest possible running of the graphics card. The grey-black cooler cover comes complete with RGB-LED lighting and the backplate serves to provide the graphics card improved stability and rigidity.

The NVIDIA GeForce GTX 1080 Ti Graphics CardThe NVIDIA GeForce GTX 1080 Ti graphics card is based on the GP102-GPU with Pascal architecture and represents the flagship of the GeForce GTX 10-series. Employing a massive 11 GB of VRAM, a huge 3.584 CUDA cores as well as high GPU clock frequencies, the GTX 1080 Ti was made for 4K/UHD-resolution gaming, and represents an excellent choice for experiencing the best that Virtual Reality has to offer - as demanded by HMDs like the HTC Vive.
Forged with the new 16-nm FinFET manufacturing process, the GPU is able to fit a sensational 12 billion transistors onto the 471 mm² GP1102 chip. The 16 nm process, in combination with the Pascal architecture, also permits a notable reduction in power consumption with a 250 Watt TDP. This low TDP is combined with a cooler design appropriate for maintaining high boost clocks over long periods of time.
The GeForce GTX 1080 Ti graphics card is equipped with a gigantic 11 GB GDDR5X VRAM which is connected to the chipset by means of a 384-bit memory interface. GDDR5X VRAM has a 50% higher bandwidth when compared to GDDR5 VRAM which, when the high memory clock frequencies, allows a memory bus bandwidth of 484 GB/s.
Features supported by the GeForce GTX 1080 Ti include, among others, Direct X12, OpenGL 4.5, Vulkan, 3D Vision, NVIDIA Surround, Tessellation, PhysX, Ansel, CUDA, NVENC, SMX, GPU Boost 2.0, Adaptive Vertical Sync, SLI, G-Sync, VXGI, Super Resolution, 4K Ultra HD Support, 4K Surround, NVIDIA ShadowPlay, NVIDIA GameStream, HDCP and Simultaneous Multi-Projection 4.0.
Virtual Reality and 4K Gaming with the NVIDIA GeForce GTX 1080 TiSimultaneous Multi-Projection 4.0 (SMP) allows the GeForce GTX 1080 Ti to conserve geometry-rendering performance by rendering multiple perspectives (known as "Viewports") in a single pass. The Pascal architecture supports up to 16 of these Viewports simultaneously. SMP is primarily of interest to users of Virtual Reality (VR) and can massively improve the performance of the GTX 1080 TI during VR-related applications when compared to its predecessors.
One component of SMP 4.0 is known as Lens-Matched Shading (LMS), which optimises image rendering to prevent parts of the image unseen by the user in VR (due to the lenses) to remain unrendered. The curved lenses are situated between the eyes and the display to allow the image to be correctly adjusted.
Asynchronous Compute is the simultaneous execution of both the necessary calculations and render requests, and this is especially relevant in the context of APIs like DirectX 12 or Vulkan. As a result, faster and more efficient communication between the CPU and GPU occurs. The advent of Pascal architecture means that the GTX 1080 Ti is capable pausing calculations and buffering them, also known as "pre-emption".
Asynchronous Timewarp and Interleaved Reprojection technologies techniques utilised by VR HMDs to prevent frame-rates falling below 90 Hertz. Asynchronous Compute allows the GP102 GPU to better prioritise these rendering techniques to guarantee an incredible VR experience.
In order for the card to reach its full potential in the long-term, new drivers should be downloaded and installed from NVIDIA or the third party manufacturer at regular intervals.
