V Pentium Family CPUs
Cyrix and AMD are out in the marketplace selling their CPUs and math co processors, calling them 80386, 80387, just like Intel's. As you can guess, Intel is not happy about this. The firm was so mad; they went to court to stop their competitors. Ha-Ha, you can't copyright or patent numbers, the judge says. So Intel runs a contest to come up with a name for the 80586 that isn't a number. Penta means five, right? And on the 19th of October 1992, the name Pentium was announced.
As usual, the Pentium was backward compatible, while offering new features. The revolutionary step in this CPU was twin data pipelines. This enabled the CPU to execute two instructions at the same time. This is known as super scalar technology, typically found in RISC based CPUs.
The Pentium uses a 32-bit expansion bus, however the data bus is 64-bits which means the system memory is addressed at 64 bits at a time. This is an important distinction to remember when working with some types of RAM packaging, which is seen in the next chapter.
