Core Processors (Intel Pentium Series)

Core Processors:

Introduce in Jun 20007. A multi-core processor is a processing system composed of two or more independent cores (or CPUs). The cores are typically integrated onto a single integrated circuit die (known as a chip multiprocessor or CMP), or they may be integrated onto multiple dies in a single chip package. A many-core processor is one in which the number of cores is large enough that traditional multiprocessor techniques are no longer efficient.
A dual-core processor contains two cores, and a quad-core processor contains four cores. A multi-core processor implements multiprocessing in a single physical package. Cores in a multi-core device may be coupled together tightly or loosely. For example, cores may or may not share caches, and they may implement message passing or shared memory inter-core communication methods.

Pentium IV: (Intel Pentium Series)

Pentium IV:

In November 2000 Intel introduced the new and very powerful high-end chip Pentium 4 formerly known as codename “WILLAMETTE”.
The Pentium 4 is a completely new processor holding several new designs. Here is a highlight.

1. 400 MHZ front side bus of 128-bit width.
2. Execution traces Cache.
3. 20-KB L1 Cache and 256 KB L2.
4. The ALU (Arithmetical logic unit) runs at twice the clock speed.
5. A new socket for simple MB design.
6. Clock frequency from 1500 MHZ.
7. 20 stages pipeline.
8. SSE2 and 128 bit MMX.
9. A new 423 pins socket design.
10. 42 millions of transistors.
11. Dual Ram bus memory channel with 850 chipset.
12. Only single processor mode available.

Pentium III: (Intel Pentium Series)

Pentium III:

The Pentium 111 was introduced in 1999. It was designed for the consumer and business market desktop computers. The Pentium –111 included 70 new instruction designed to enhance 3D imaging, and video applications, initial computers with the Pentium 111 operated at 500 MHZ but the Pentium 111 has been tested (By Intel) at speeds of over 1 GHZ using special cooling techniques.

The Pentium (intel Pentium Series)

The Pentium:

The Pentium, introduced in 1993, retains the 32-bit address bus of the 80486 but doubles the data bus 64 bits. The Pentium retained the 32 bit registers of the 486 but made it possible to deal with the 64 bit data bus by adding a second execution unit. The Pentium also has two 8-K bytes cache memories, one for instructions and for data. The original Pentium operated at a clock frequency of 60 MHZ or 233 MHZ.
