Nvidia’s GeForce GTX 990M is based on ‘Maxwell’ GM204 graphics chip

Nvidia Corp. is gearing up to introduce its GeForce GTX 990M, an all-new graphics processing unit for laptops. Despite expectations, the company will continue to use its GM204 chip for its new adapter designed for gaming notebooks.

Nvidia GeForce GTX 990M graphics processing unit for mobile computers will use fully-fledged GM204 processor with 2048 stream processors, 128 texture units, 64 raster operations pipelines and 256-bit memory interface. The GPU operates at 1190MHz, according to ComputerBase, which tried out Asustek’s new ROG GX700 laptop powered by the new GPU.

The new GeForce GTX 990M should demonstrate performance on par with desktop GeForce GTX 980, which means that the new graphics adapter will be the highest-performing graphics solution for mobile computers. Thermal design power of the fully-fledged GM204 is pretty high, hence, the GeForce GTX 990M will be used only for ultra-high-end laptops.

Previously it was expected that Nvidia will use a version of its GM200 graphics chip for its GeForce GTX 990M adapter. However, even at low clock-rate, the GM200 may be too hot and power-hungry for laptops.

Nvidia did not comment on the news-story.
