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.
