For as quickly as GPU architecture is advancing, particularly in the power efficiency space, the mobile sector is still somewhat partial to cooling and energy limitations.<\/p>\n

It\u2019s for that reason that mobility GPUs are usually significantly dialled down when compared to their desktop brethren.<\/p>\n

Take the comparison between GeForce GTX 980 and GTX 980M for example: The GTX 980 has the GM204\u2019s full complement of 2048 CUDA cores, 64 ROPs and 128 TMUs, all of which are clocked at 1126 MHZ and can be boosted to 1216 MHZ. On the other hand, the GTX 980M sports just 1536 CUDA cores, 96 TMUs and, fortunately, all 64 ROPs, but they\u2019re running at a slower core speed\u2013 1038 MHZ.<\/p>\n

That means just 75% of the desktop equivalent\u2019s performance, which, while good, isn\u2019t quite good enough for NVIDIA.<\/p>\n

NVIDIA\u2019s latest mobility flagship, which the press has named the GTX 990M, was unveiled at a Chinese technology conference last month<\/a>.<\/p>\n

And while it\u2019s reported to use the full GM204 GPU, much like the GTX 980, it wasn\u2019t confirmed until now.<\/p>\n

\"NVIDIA-GM204-GPU\"<\/a><\/p>\n

At IFA 15<\/a> the site Computerbase got the chance to play around with ASUS\u2019 shiny, new water cooled ROG GX700 notebook. The GPU they found inside was not a GTX 980M, but something altogether more powerful.<\/p>\n

\"ASUS<\/a><\/p>\n

The GTX 990M, according to what Computerbase was able to report, uses the entire GM204 GPU, which means 2048 CUDA cores, and it runs at an impressive 1190 MHz to boot.<\/p>\n

While NVIDIA\u2019s mobility cards do not offer boost functionality, the GTX 990M still has a higher base core speed than even the GTX 980.<\/p>\n

Alongside the fully-fledged GM204 GPU is 8GB of GDDR5 RAM running at 2.5 GHz (5GHz equivalent), which is 2 GHz slower than its desktop part, but still manages a fairly impressive 160 GB\/s.<\/p>\n

\"NVIDIA-GeForce-GTX-990M-Specs\"<\/a><\/p>\n

The GTX 990M puts NVIDIA firmly at the top of the mobility GPU market, and by a good distance. AMD really doesn\u2019t have anything capable of competing.<\/p>\n

Expect any notebook\/laptop equipped with the GTX 990M to cost, well, a lot, but it is purely for the top end of the enthusiast spectrum.<\/p>\n
