Essentially an Intel 486DX microprocessor witha 16 kilobyte on-chip cache.The DX4 is the fastest member of the Intel 486 family. 75and 100MHz versions are available. At an iCOMP index ratingof 435, the 100 MHz DX4 performs up to 50% faster than the 66MHz Intel DX2. The DX4's clock multiplier allows theprocessor 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 integratedfloating point unit.Like the other 486s, the DX4 achieves performance through aRISC integer core that executes frequently used instructionsin a single clock cycle (the Pentium's can executemultiple instructions in a single clock cycle).Low power consumption has been achieved with SL Technologyand a 0.6 micron manufacturing process, giving 1.6 milliontransistors on a single chip operating at only 3.3 Volts."IntelDX4" is the entire name, the "486" has been dropped andI am assured that there is no space in the same.
