The Pentium
processor with MMX technology extends the Pentium processor family, providing performance
needed for mainstream desktop applications as well as for workstations. The Pentium processor with MMX
technology is compatible with the entire installed base of applications for MS-DOS*, Windows*, OS/2* and
UNIX*. The Pentium processor with MMX technology is the first microprocessor to support Intel MMX
technology. Furthermore, the Pentium processor with MMX technology superscalar architecture can execute two
instructions per clock cycle. Enhanced branch prediction and separate caches also increase performance. The
pipelined floating-point unit delivers workstation level performance. Separate code and data caches reduce
cache conflicts while remaining software transparent. The Pentium processor with MMX technology has
4.5 million transistors and is built on Intel's enhanced CMOS silicon technology.
The Pentium processor with MMX technology may contain design defects or errors known as errata that may
cause the product to deviate from published specifications. Current characterized errata are available on
request.
