Review of Intel Processors - Inside a Central Processor Unit (CPU) ================================================

In this second series of building your own DIY PC computer, we are going to delve more in depth into the main component of a computer which determines the level of performance: i.e the CPU (Central Processor Unit)

There are many models of CPUs in the market, and there are also pros and cons to each. Every often, a certain model of processor will require a corresponding compatible type of motherboard to support, so this is the first thing to take note when choosing the motherboard and the CPU. These 2 have to be compatible. i.e: AMD processors go with AMD compatible motherboard and Intel processors go with Intel compatible motherboard.

Although there are two major CPU manufacturers (AMD and Intel), in this article, we will be looking mainly at Intel processors although discussion for AMD processors will also be of similar nature.

For Intel, their processors are categorized into 3 main groups: namely notebook processors, desktop processors, and Internet Device Processors.

Since majority of "build your own DIY PC" enthusiasts are aiming for desktops upgrades, it is great time to explore more on Intel Desktop processors currently in the market in this article.


==============================
Intel Desktop Processors Selection
==============================


Different needs call for different products. Be it the need for web surfing, or entertainment/gaming or managing team projects, there is some suitable processor which can handle this task for you.

4 main processors have been created by Intel:
i) Intel Core2 Duo
ii) Intel Core2 Quad
iii) Intel Core2 Viiv
iv) Intel Core2 Extreme
v) more...

These names sure sounds exciting, lets find out more details on the basic terminology within the CPU chip, and then what differentiates the different type of processors.

=============
Basic Terminology
=============


Processor models mainly vary according to number of cores, Front Side Bus, Cache size, Clock speed, RAM speed and chip technology.

Different needs call for different specifications. For example: For gaming, streaming video or watching movies, a high clock speed and FSB is recommended, while for resources-intensive programs, the more L2 Cache available the better. If focus is on multi-tasking activities, more processor cores are preferred for better seamless parallel operation.

Great but what does each of these terminology mean to us? Lets check out more next.

Small Note: Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families.

Cores
+++++++
For higher efficiency, multi-core processors are introduced which consists of two or more distinct processors in the same integrated circuit. Each core can work separately or together on one large task. With threading introduced, instructions passed by programs can now be concurrently processed by more than one processor. This technology enables the user to perform several multi-tasking tasks at one go, saving you time and costs in the long run.

Clock Speeds
+++++++++++++
Simple: Higher clock speed = Higher Processing SpeedClock speed measures how fast a processor performs an activity. It is expressed in gigahertz (GHz) which means the number of billion cycles per second.For example: A 2.66GHz computer is expected to perform faster than a 2.4GHz computer, but other factors also need to take into consideration such as front side bus, number of cores, speed of memory chips etc...you get the idea: these components are interdependent.

Front Side Bus
+++++++++++++
This acts as the data transfer interface between the CPU and the memory. The higher the Front Side Bus (FSB) values, the faster the data transfer rate, and better computer performance. A point to note is that the FSB values should be matched to that of the processor for maximum efficiency.

L2 Cache
+++++++++++++
Cache works like a storage bank. It stores the information most often used and accessed, and retrieves them very fast when needed. More cache means less system lag. More advanced systems are even talking about L3 Cache as well. So Cache is also an exciting area of development in processors.

Chip Technology
+++++++++++++
This part of knowledge may not so important to a typical computer user, but it is cool to know the technology that is driving the miniaturizing of dies and hence the increase in processors performance either through more cores, or higher clock speed, FSB, cache or improved data communication and transmission.

Technology Transition for recent years have gone from 65nm to 45nm. Benefits appears in more densely packed transistors, with innovative material used which leak less energy, produce less heat, and switch faster hence providing higher efficiency and processor performance.
After understanding the backbone of processors, it is also exciting to know that there is a dedicated group of software and hardware developers to support ever-growing technology needs, so there is definitely something for everyone.

Next, we take a look at the different type of processors developed by Intel, and their core benefits and usage.

==============================================
Differentiation between the different type of processors ==============================================
