Laptop Performance considerations before making your Laptop Purchase

With so many different applications, functions, and specialized computing tasks available today, choosing a laptop has become a bit more daunting in recent years. That is to say, in the world of laptops, the definition of a “good” laptop often depends on the function(s) the end user needs it to do. Unfortunately, what sometimes happens is that base their purchasing decisions on someone else’s criteria of good. This can lead to a person not getting as much computer as they can for their money, and/or paying too much for features they do not need or use.

To that end, this article is intended to break down the various parts of a laptop, explain their importance, and compare the options available. While time and space restrict us from dissecting every model of every component available, we will discuss some of the more common options and the difference between. Finally, we will focus mainly on Laptop Performance, rather than all of the “bells and whistles” available. This guide will be written in a series-with 1-2 elements discussed daily. Be sure to check back in the next days for the complete series.

CPU:

The CPU-or processor-is the “brains” of a laptop or desktop, and thus is arguably the most important factor in determining Laptop Performance. This element drives the processing of the computer. It organizes and carries out tasks and operations. It is the CPU which is primarily responsible for speed, multi-tasking ability, and overall function.

How to choose based on CPU:

1. Cores, Cores, Cores. Generally speaking, the more cores there are in a CPU, the better. Thus, quad cores typically are better than dual cores which are better than single core–if all things are equal.

2. How fast does your bus go? Another thing that is often overlooked in determining Laptop Performance is bus speed. In terms of processing, the “front-side bus” is the main area of concern. The higher the number the better (ie 800mhz is better than 677mhz)

3. Category of CPU: There are many categories/families of CPUs. Within those families, there are individual CPUs that vary in functionality and Performance. Generally speaking, within each family, there are two things to consider. The first is the speed, or the MHz of a CPU. However, it is only one piece of the puzzle. The second thing to look at is what number the processor is within the family. Generally, the higher the number the more efficient processor. (Ie: Intel Core 2 Duo T6400 is generally a bit (very small bit) better than the Core 2 Duo T5800. However, this is not always the case. If it is available, be sure to check bus speed.

CPU Categories by Ranking (best to last)

1. Intel Core i7-Very few laptops have this, but they are out there. In terms of Laptop Performance, these are considered the best. However, they are very pricey

2. Intel Core 2 Quad-Available on a few laptops

3. AMD Phenom II (Some of these outperform Core 2 Quad slightly-II 965)

4. Intel Core 2 Duo

5. AMD Athlon II

6. AMD Turion Dual Core

7. Intel Pentium

8. AMD Athlon I

9. Intel Celeron

For ease of Decision making, I would suggest breaking it down to:

- Intel Core 2 Duo

-AMD Athlon II (make sure it is not basic Athlon I)

-AMD Turion

-Intel Pentium

Note that there are variations of each family that performs slightly better than some in the next higher category. Use this chart merely as one of the tools you use to narrow down your choices. Before Buying, be sure to look specific processors in terms of their specific performance.
