Nvidia officially reveals their GTX 1080Ti

Nvidia has officially announced their plans to release their GTX 1080Ti GPU, with the company intending to offer GTX 980Ti owners the chance to "pre-order" the GPU early or take part in a "step up" program.

Pre-orders for the GTX 1080Ti have not started yet, though it looks like we can expect more information on this GPU within the next few weeks/months.

Right now Nvidia has not released any detailed specifications on this upcoming GPU and has not set a firm launch date, merely confirming the existence of the GPU. This finally answers our longtime question "where is the GTX 1080Ti?" but is sadly does not give us any clarification when it comes to when we can expect the company to launch the new GPU.

The GTX 1080Ti is thought to be a cheaper variant of Nvidia's Titan X Pascal, currently costing $1200 in the US. Nvidia's GTX Titan series GPUs has never been about Value for money, but the company has always released a lower end GTX variant like the GTX 780Ti or GTX 980Ti to provide gamers with enthusiast-grade performance with relatively good value.

Right now we have no idea if or when Nvidia plan on releasing their GTX 1080 Ti GPU, though we do expect Nvidia to release something in response to AMD's upcoming Vega-series GPUs in early 2017.

When looking at Nvidia's previous GTX Titan GPUs one trend is clear, that the lower priced Ti variant of every Titan GPU has half of the VRAM of its Titan equivalent. The GTX 780Ti had 3GB of VRAM compared to the 6GB on the Titan Black and the GTX 980Ti had 6GB compared to the Original GTX Titan X's 12GB.

Today's Titan has 12GB of GDDR5X VRAM and simply halving it would result in a GTX 1080 Ti that had 6GB of VRAM, something that Nvidia would simply not release given the fact that their GTX 1080 has 8GB of VRAM. With the GTX Titan series always having a VRAM capacity lead over their desktop counterparts we expect the GTX 1080Ti to have either 10GB of GDDR5X VRAM, using a cut-down memory bus to allow for the GPUs lower VRAM capacity.

In order for the GTX 1080Ti to have less VRAM than the GTX Titan X but more than the 1080 Nvidia will need to use a smaller memory bus size, changing their 384-bit memory bus to a 320-bit memory bus, allowing Nvidia to use fewer VRAM chips and create a hypothetical 10GB GTX 1080Ti.

This decrease in memory bus size will also result in a decrease in overall memory bandwidth, lowering the total memory bandwidth from 480GB/s down to around 400GB/s.

Nvidia's new job listing markets the GTX 1080Ti as a GTX 980Ti replacement, with Nvidia planning to offer their users with an upgrade/step-up system for owners their existing GTX 980Ti GPU.

At this time Nvidia has not set a firm release date for the GTX 1080Ti, though we expect the GPU to be released in early 2017.
