It seems NVIDIA is getting to ready to release two new mobile Maxwell GPUs in Q2 2016, the GTX 970MX and GTX 980MX. With the company already dominating the high end notebook market and 14nm/16nm next generation GPUs on their way like Polaris, the timing of this release seems a little odd.
Both GPUs will be positioned as slightly more powerful than their existing GTX 970M and GTX 980M counterparts with increased CUDA cores, texture units, and clock speed while retaining the same TDP. In addition to the aforementioned, the 970MX has 56 ROPs vs 48 in the 970M while the 980M and 980MX have the same 64 ROPs.
WCCFTech created a table which shows the differences between the new GPUs and existing ones:

There's no word on what the price will be for these new cards or what notebooks will feature them but if I had to guess, I'd say the usual suspects like Alienware, Clevo, MSI and Asus will be among the first to have these ready.
