Pentium Pro
     
         (Known as "P6" during development) {Intel}'s
        successor to the {Pentium} processor, in development Jan 1995,
        generally available 1995-11-01.  The P6 has an internal
        {RISC} architecture with a {CISC}-{RISC} translator, 3-way
        {superscalar} execution, and {out-of order execution} (or
        "{speculative execution}", which Intel calls "{Dynamic
        Execution}").  It also features {branch prediction} and
        {register renaming}, and is superpipelined (14 stages).
     
        The P6 is made as a two-chip assembly: the first chip is the
        {CPU} and 16 kilobyte {first-level cache} (5.5 million
        {transistors}) and the other is a 256 (or 512) kilobyte
        {second-level cache} (15 million transistors).  The first
        version has a clock frequency of 133 Mhz and consumes about
        20W of power.  It is about twice as fast as the 100 MHz
        Pentium.  The original 0.35 micron versions of the Pentium Pro
        released on 1995-11-01 run at 150 and 166 Mhz for desktop
        machines and up to 200 Mhz for {servers}.  Heat disspation is
        about 20 Watts.
     
        The Pentium Pro is optimised for 32-bit software and runs
        16-bit software slower than the original Pentium.  The
        successor was the {Pentium II}.
