Form factor & compatibility

Information on GeForce GT 635M and GeForce GTX 1080 11Gbps compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.

Laptop size	large	no data
Bus support	PCI Express 2.0	no data
Interface	PCIe 2.0 x16	PCIe 3.0 x16
Length	no data	267 mm
Width	no data	2-slot
Supplementary power connectors	no data	1x 8-pin
