Processors amoung the ages

Before you read on, these are a couple things you need to know:
Bit : Also called binary digit. A single, basic unit of information, used in connection with computers and information theory.
RAM : Short for Random Access Memory, this is the most common type of memory found in computers.
MHz : Short for Megahertz.

In the start, there was the Intel 8086...
This was created in 1978. It was a 16 bit processor and it talked with its card which was a 16 wire data connection. It has 20 address lines which means it could talk with up to 1MB of RAM. The chip was available in 5,6,8 and 10 MHz versions.

And then there was the Intel 8088...
This was created in 1979, only a year after the Intel 8086. It is identical to the Intel 8086, but the only difference to this was how it handled its address wires. This chip was chosen for the first IBM PC.


Afterwards there was the NEC V20 & V30...
This was created in 1981. These are exact clones of the Intel 8086 & the Intel 8088, except they're 30% faster.

Then along came the Intel 80186...
This one was created in 1980. It was a very popular chip. There have been many versions of this chip but there were 2 main types that a buyer could choose from, the CHMOS or the HMOS, depending on what the buyer needed. The difference was that the CHMOS chip could run twice the clock speed and only a quarter of the HMOS chip.

Now there was a Intel 80286...
This was created in 1982.

The CPU Frequency (MHz) from 1993 to 2005.
