Rumor: Nvidia brings desktop GPUs GTX 1070 and 1080 to laptops

Nvidia is reportedly not coming with a GTX 1070M and GTX 1080M with derived GPUs for laptops. The manufacturer would use the GPUs of the desktop versions of the GTX 1070 and 1080, as it did before with the GTX 980.

Nvidia will only lower the TDP with the GTX 1070 and 1080 for laptops, but the GPUs will remain the same, PCGamer writes based on information the site heard from its sources during the Computex. The manufacturer also does not intend to release special M variants of the high-end graphics cards for laptops. The GTX 1070 and 1080 have TDPs of 150W and 180W respectively. While this is low compared to previous video cards, laptop clocks need to be reduced to lower tdp, according to PCGamer.

The site thinks the first laptops with the video cards will appear in August or September. Videocardz notes that the MXM 3.0 type B specification prescribes a maximum TDP of 100W and that Nvidia will probably use its own module if the rumor is correct. An in-house developed module could increase costs.

The GTX 1070 and 1080 are both built around the GP104 GPU. That GPU is based on the new Pascal architecture and is produced on a 16nm finfet process. Nvidia has activated 1920 shaders for the GTX 1070 and the full 2560 for the GTX 1080. In the past, Nvidia always used derived GPUs for laptops. For example, the GPU of the GTX 980M is a GM204 with 1536 shaders, while the GM204 of the GTX 980 for desktop cards has 2048 shaders. Last year, Nvidia brought the GTX 980 with the full GPU to laptops for the first time.

MSI and Gigabytes Aorus, among others, come with gaming laptops with GPUs of Nvidia’s new generation, TweakTown writes. The site refers to the name GTX 1080M but admits that this name was not mentioned by the companies. Nvidia will probably keep the M designation for less high-end GPUs for laptops, such as with cards with the GP106, which seems to be coming to laptops in MXM form.
