Form Factor & Compatibility

Information on GeForce 820M and Playstation 3 RSX 65nm 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.

Bus support	PCI Express 2.0	no data
Interface	PCIe 2.0 x16	IGP
Width	no data	IGP

VRAM Capacity and Type

Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated video RAM and use a shared part of system RAM.
