Nvidia are rumoured to releasing their GTX 1080 GPU in May which is expected to come with 8GB of GDDR5X memory and be powered by a single 8-pin power connector.
It is expected that it will be revealed at the Nvidia GTC event on April 4-7, 2016. This should be the official launch of the new Pascal GPU architecture.
Rumour’s indicate it won’t be a massive upgrade in terms of graphics power, and follow a similar pattern as the last generation with the GTX 1080 as a direct replacement for the GTX 980Ti with larger more powerful Pascal designs coming later.
The major improvement appears to be a lower TDP and power consumption, with it require just a single 8-pin PCIe power connector. These power saving will be due to Nvidia using the smaller and more efficient 16nm FinFET Processing node from TSMC and making several key architectural changes to Pascal.
This GPU is also rumoured to be using 8GB GDDR5X VRAM instead of HBM, with HBM being expected to power Nvidia's future Flagship Pascal GPUs (Big Pascal).
At this time the GTX 1080 GPU is rumoured to be launching on May 27th and is rumoured to have dual Displayport, a single DVI and a single HDMI 2.0 connections, though at this time we do not know if the GPU will support DisplayPort 1.3.
While the launch is no doubt exciting to any PC gamer, it does sound like gaming in 4K with max settings using a single GPU could be some way off!
