MMX is a single instruction, multiple data (SIMD) instruction set designed by Intel, introduced in 1997 with its P5-based Pentium line of microprocessors, designated as "Pentium with MMX Technology".[1] It developed out of a similar unit introduced on the Intel i860, and earlier the Intel i750 video pixel processor. MMX is a processor supplementary capability that is supported on recent IA-32 processors by Intel and other vendors.MMX has subsequently been extended by several programs by Intel and others: 3DNow! and ongoing revisions of Streaming SIMD Extensions.

MMX is a Pentium microprocessor from Intel that is designed to run faster when playing multimedia applications. According to Intel, a PC with an MMX microprocessor runs a multimedia application up to 60% faster than one with a microprocessor having the same clock speed but without MMX. In addition, an MMX microprocessor runs other applications about 10% faster.

The MMX technology consists of three improvements over the non-MMX Pentium microprocessor:

57 new microprocessor instructions have been added that are designed to handle video, audio, and graphical data more efficiently.
A new process, Single Instruction Multiple Data ( SIMD ), makes it possible for one instruction to perform the same operation on multiple data items.
The memory cache on the microprocessor has increased to 32 thousand bytes, meaning fewer accesses to memory that is off the microprocessor.
