Pentium:
Pentium is the fifth-generation x86 architecture microprocessor released by Intel Corporation in 1993. It succeeds the 486 processor. Though it was named as Pentium this chip was actually to be named 80586 or i586.
Intel first introduced the Pentium in two versions: 60MHz and 66MHz. The 60MHz version though it works fine, it was slow & didn't quite pass the 66MHz quality-control cut. Hence 66MHz version was released.
Pentium has 3.1 million transistors which use a 32-bit address bus, 64-bit data path, 16K on-chip cache and it has speed which varies from 60MHz to 200MHz. The processor is a combination of two 486DX chips in one larger chip. The advantage of this architecture is that each chip can execute instructions independent of each other. This type of parallel processing ability is called super scalar.
