The Pentium
The next member of the Intel family of microprocessors was the Pentium, introduced in the year 1993. With the Pentium, Intel broke its custom of numeric model names partly to prevent other chip manufactures from by using same numeric names, which inferred that their products were functionally identical to Intel's chips. However The Pentium is yet considered part of the 80x86 series.
The Pentium chip itself represented another leap forward for microprocessors.The power and speed of the Pentium dwarfed all of its predecessors in the Intel line. In practical terms this means is that the Pentium runs application programs about 5 times faster than a 486 at the same clock speed. Part of the Pentium's speed comes from a super-scalar architecture, which permit the chip to process more than 1 instruction in a single clock cycle.
