I may have confused the terminology. My point is that it's integrated into the laptop and isn't an upgradable component.
Actually, that is incorrect.
The Radoen HD 8970m is an MXM format graphics card for laptops; version 3.0b I think.
The MXM formats are basically graphic cards designed specifically for expensive gaming laptops with an MXM port. The version denote the size of the MXM graphics card; the higher the number the larger / thicker the graphics card. That means you cannot stick a MXM 3.0 graphics card in a laptop that can only use MXM 2.0 graphics card.
The MXM format is reserved only for high end graphics cards so that you will never be able to find a GT 730m MXM card. Additionally, some laptop manufacturers solder MXM cards into the MXM slot which make them non-upgradeable.
