The Pentium® processor 75/90/100/120/133/150/166/200 extends the Pentium processor family, providing
performance needed for mainstream desktop applications as well as for workstations and servers. The Pentium
processor is compatible with the entire installed base of applications for DOS*, Windows*, OS/2*, and UNIX*.
The Pentium processor 75/90/100/120/133/150/166/200 superscalar architecture can execute two instructions
per clock cycle. 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 75/90/100/120/133/150/166/200 has 3.3 million
transistors and is built on Intel’s advanced 3.3V BiCMOS silicon technology. The Pentium processor
75/90/100/120/133/150/166/200 has on-chip dual processing support, a local multiprocessor interrupt controller,
and SL power management features. The Pentium processor may contain design defects or errors known as
errata which may cause the product to deviate from published specifications. Current characterized errata are
available upon request.
