According to a report from Korean site Hardware Battle, Nvidia is working on two new GM204 Maxwell-based mobile GPUs, the GTX 980MX and the GTX 970MX, both with higher number of CUDA cores as well as higher clocks compared to the currently available Geforce GTX 980M and the GTX 970M. The earlier announced Geforce GTX 980 Notebook, which is pretty much a desktop version of the GM204 GPU, will still remain the flagship mobile GPU in Nvidia's lineup.

While Hardware Battle did not specify its source, the site manage to get most of the specifications for the new GPUs. According to the table made by Videocardz.com, the Geforce GTX 980MX will pack 1664 CUDA cores, 104 TMUs and 64 ROPs. Its GPU will work at 1048MHz and it will feature 4GB or 8GB of GDDR5 memory clocked at 5000MHz and paired up with a 256-bit memory interface. With both higher CUDA core count as well as higher clocks, the GTX 980MX should end up significantly faster compared to the currently available GTX 980M GPU, with 1536 CUDA cores and 1038MHz GPU clock.

The Geforce GTX 970MX will pack 1408 CUDA cores, 88 TMUs and 56 ROPs which makes it decent boost compared to the GTX 970M, which featured 1280 CUDA cores. The upcoming Geforce GTX 970MX works at 941MHz for the GPU and will feature 3GB or 6GB of GDDR5 memory clocked at 5000MHz.

Unfortunately, Hardware Battle did not reveal any information regarding the TDP of these two new GPUs but we doubt that it will be much over 125W and 100W seen on the GTX 980M and the GTX 970M.

The source also did not reveal any details regarding the launch date but we might have seen them launch sometime in Q2 2016, with notebooks based on those GPUs launched at Computex 2016 show which kicks off on May 31.
