Extending this sequence, an "ExpressCard" is the logical and architectural equivalent of a PCI Express card for a portable electronic device such as a laptop. Physically, an ExpressCard slot in a laptop outwardly resembles a PC Card slot, however ExpressCard slots are not backwards compatible to PC Cards.
CFexpress 2.0 type B Gen4 Cards are basically already available in the form of the Seagate Storage Expansion Card for Xbox Series X and Xbox Series S, which are mechanically incompatible to most slots because of their lengthened housing. [5] The CFexpress 4.0 standard was announced on 28 August 2023.
ExpressCard-to-CardBus and Cardbus-to-ExpressCard adapters are available that connect a Cardbus card to an Expresscard slot, or vice versa, and carry out the required electrical interfacing. [20] These adapters do not handle older non-Cardbus PCMCIA cards. PC Card devices can be plugged into an ExpressCard adaptor, which provides a PCI-to-PCIe ...
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.
A PCI Express card fits into a slot of its physical size or larger (with x16 as the largest used), but may not fit into a smaller PCI Express slot; for example, a x16 card may not fit into a x4 or x8 slot. Some slots use open-ended sockets to permit physically longer cards and negotiate the best available electrical and logical connection.
