Form factor & compatibility
Information on Steam Deck GPU and GeForce RTX 4070 Mobile 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 | no data | large |
| Interface | no data | PCIe 4.0 x16 |
| Length | 298 mm | no data |
| Supplementary power connectors | None | no data |
