X8

X8 is an alphanumeric designation used in multiple, distinct domains. Without a specific context, it does not refer to a single concept but rather to a label that often signals eight units, eightfold, or an eight-by dimension in different settings.

In mathematics and computing, “x8” is not a standard mathematical notation for multiplication. Eight times x is written as 8x. The string “x8” can appear in variable names or labels in code or documentation. In digital electronics and memory technology, “x8” describes the data width of a component: an 8-bit wide data bus or chip. It contrasts with x4, x16, etc., which indicate different bit widths. In hardware specifications, “x8” sometimes appears to indicate a module that has eight data lines.

In transportation and automotive contexts, “X8” or “8x8” commonly denotes eight wheels with drive to all axles, i.e., an eight-by-eight configuration, used in trucks, heavy transport, and some military vehicles. The designation can identify a model, a drivetrain layout, or a system with eight simultaneous units.

In product naming, many brands use “X8” as a model suffix for electronics, drones, cameras, or vehicles. The name often signals a sense of advanced capabilities or a platform-wide designation rather than a single fixed feature set. Because the meaning is entirely context-dependent, the same label can refer to different products in different industries.
