NotebookCheck spoke to its sources and was unable to confirm yesterday's rumor about a new GTX 900MX refresh from NVIDIA. Instead, the site received confirmation that a Pascal-based refresh is still on track for the end of 2016 or early 2017.
Furthermore, NotebookCheck also claims AMD is unlikely to launch Polaris-based notebook GPUs before the start of 2017.
The new Polaris architecture from AMD is to be expected mid-2016, but the chances of consumer notebooks shipping with the new AMD GPU before the start of 2017 will be small.
So far, there has been no reason for Nvidia to upgrade its unrivaled top chips GeForce GTX 970M and GeForce GTX 980M. And then there there is also the Geforce GTX 980, which is completely out of range for current AMD graphics solutions.
