According to recent reports, NVIDIA is working on a GeForce GTX 990M GPU for notebooks. The chip allegedly carries the codename “N16E-GXX” and is expected to be released by Q4 this year.
Independent industry insiders have revealed to Notebookcheck that the GTX 990M chip will be based on the NVIDIA Maxwell GM204 architecture, similar to the desktop GTX 980 card. The card will allegedly have a TDP around 100 to 185+W, so notebook manufacturers will need to come out with an impressive cooling system on their notebooks for optimum performance. Due to the high TDP, the chip will reportedly be soldered onto the motherboard and not be offered as a MXM solution.
As far as performance goes, the Notebookcheck report claims it will be closer to the performance of the current GTX 980M in SLI, which means slightly higher performance than a standard desktop GTX 980.
It is rumored that the GTX 990M could be priced twice as high as the current GTX 980M. NVIDIA could announce the card by the end of September, which means the first notebooks with the GTX 990M could be out by Q4 this year.
