IntelDX4
     
         Essentially an {Intel 486DX} {microprocessor} with
        a 16 kilobyte on-chip {cache}.
     
        The DX4 is the fastest member of the {Intel 486} family.  75
        and 100MHz versions are available.  At an iCOMP index rating
        of 435, the 100 MHz DX4 performs up to 50% faster than the 66
        MHz {Intel DX2}.  The DX4's {clock multiplier} allows the
        processor to run three times faster than the {system clock}.
        This performance is achieved in part by a 16K on-chip {cache}
        (double that of the other 486s).  The DX4 has an integrated
        {floating point unit}.
     
        Like the other 486s, the DX4 achieves performance through a
        {RISC} integer core that executes frequently used instructions
        in a single {clock cycle} (the {Pentium}'s can execute
        multiple instructions in a single clock cycle).
     
        Low power consumption has been achieved with {SL} Technology
        and a 0.6 micron manufacturing process, giving 1.6 million
        {transistor}s on a single chip operating at only 3.3 Volts.
     
        "IntelDX4" is the entire name, the "486" has been dropped and
        I am assured that there is no space in the same.
