M.2

M.2 is a specification for internally mounted computer expansion cards, primarily used for solid-state drives (SSDs), not video cards. While some graphics cards may use M.2 slots for specific functions, M.2 is mainly designed for storage devices.

M.2 video cards are specialized, compact graphics solutions that use an M.2 NVMe slot (typically M-Key) to add display outputs to industrial PCs, servers, or systems with limited PCIe slots, often featuring low-power designs. These are not for gaming, but rather for basic display functionality.
