TERMS USED TO DESCRIBE CPUS Data Bus Size This is the number of bits that the CPU send or receive
from other components in the computer. 8 bits means that the CPU can send or receive
data in chunks of 8 bits. Word Size This is the number of bits that the CPU can deal with
internally at the same time. A word size of 16 bits means that the CPU can deal with data
in 16 bit chunks. A CPU with a larger word size can deal with more data simultaneously.
Address Bus Size This is used for storing data in RAM. Essentially the location
of each byte that is stored in RAM has an address. This address is a number.
A CPU with a larger address bus size supports more RAM.

MULTIMEDIA EXTENSIONS (MMX)Multimedia extensions (MMX) are 57 additional instructions that are added to the CPU. These instructions speed up processing for multimedia, 3D video, standard video and sound. These instructions are based on the single instruction, multiple data (SIMD) technique.
Compared to the Pentium Classic (standard Pentium), a Pentium MMX has 32KB level 1 cache (standard Pentium has 16KB of level 1 cache).
A Pentium MMX runs other applications 10% faster, and runs a multimedia application 60% faster than a standard Pentium with the same clock speed.
Intel have since developed another version of MMX, called MMX2 (MMX version 2).

PENTIUM II
The Pentium II includes MMX and an additional twelve million transistors
It uses dual independent bus (DIB) architecture. The CPU has two buses:
One bus connects the CPU to main memory (RAM). The other bus connects the CPU to level 2 cache. The Pentium II comes in a single edge cartridge
(SEC) designed to fit into a Slot 1 connector on the motherboard.

PENTIUM III
The Pentium III is a Pentium II with extra instructions for live Internet streaming. Early models were distributed as an SEC with a Slot 1 connector. Later models came as an SEC with a Socket 370 chip form.

CELERON
The Celeron CPU is a cheaper version of a Pentium cartridge with less or no level 2 cache.
The first Celeron CPU were the 300A and 333. They fitted into a Slot 1 connector on the motherboard and ran on a 66MHz system bus. It was good for office applications such as word processors, but the lack of level 2 cache was a great disadvantage.
Intel Celeron processors are available in plastic pin grid array (PPGA) form factor.

PENTIUM 4
The Pentium 4 comes in an SEC with a Socket 423 chip. It has three levels of cache:
Level 1 cache, built in to the CPU.
Level 2 cache, which is outside the CPU but in the SEC.
Level 3 cache, which is outside both the CPU and the SEC.
It has two 20-stage superpipelines and a clock speed of 1GHz to3.73GHz. It has more MMX instructions.

The socket has 370 pin-holes - hence the name Socket 370, and it has the same size as the Socket 7. There are two differences between these sockets:
There are 6 rows of pins between the edge and the center of the processor for Socket 370 processors, and 5 rows for Socket 7 processors.
Socket 370 processors don't have 2 corner pins while Socket 7 processors don't have only one corner pin. The extra corner pin doesn't allow Socket 7 processors to fit into PGA370 socket.
