Mobile PCI Express Module (MXM) is an interconnect standard for GPUs (MXM Graphics Modules) in laptops using PCI Express created by MXM-SIG. The goal was to create a non-proprietary, industry standard socket, so one could easily upgrade the graphics processor in a laptop, without having to buy a whole new system or relying on proprietary vendor upgrades.
Smaller graphics modules can be inserted into larger slots, but type I and II heatsinks will not fit type III and above or vice versa.
Dell's Alienware m5700 platform uses a heatsink that will fit Type I, II, & III cards without modification.
MXM 3.1 was released in March 2012 and added PCIe 3.0 support.[1] [2]
First generation modules are not compatible with second generation (MXM 3) modules and vice versa. First generation modules I to IV are fully backwards compatible.
| MXM Type | Width | Length | Pins | Module Compatibility | Thermal Compatibility | Max. Power | Max. GPU size [3] | |
|---|---|---|---|---|---|---|---|---|
| MXM-I | 70 mm | 68 mm | 230 | I | I | 18 W | 35 × 35 mm | |
| MXM-II | 73 mm | 78 mm | 230 | I, II | II | 35 W | 35 × 35 mm | |
| MXM-III (HE) | 82 mm | 100 mm | 230 (232) | I, II, III | I, II, III | 75 W | 40 × 40 mm | |
| MXM-IV (Deprecated) | 82 mm | 117 mm | 230 | I, II, III, IV | I, II, III, IV |
| MXM Type | Width | Length | Module Compatibility | Thermal Compatibility | Max. Power | GPU memory bus | |
|---|---|---|---|---|---|---|---|
| MXM-A | 82 mm | 70 mm | A | A | 55 W | 64-bit or 128-bit | |
| MXM-B | 82 mm | 105 mm | A, B | A, B | 200 W | 256-bit |
MXM is no longer freely supplied by Nvidia but it is controlled by the MXM-SIG controlled by Nvidia. Only corporate clients are granted access to the standard. The MXM 2.1 specification is widely available.

The Qseven computer-on-module form factor uses a MXM-II connector, while the SMARC computer-on-module form factor uses a MXM 3 connector. Both implementations are not in any way compatible with the MXM standard.
