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.

Generations

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.

1st generation

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

2nd generation (MXM 3)

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

Specification

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.^{[citation needed]}

Other uses

VIA QSM-8Q90 Qseven computer-on-module using a MXM-2 connector

Congatec SMARC computer-on-module using MXM-3 connector

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.^{[citation needed]}
