How to choose a notebook

The very first laptop came just a few years later, the first personal computer. However, if the first PC remotely, but it looked like today's desktop systems, this is a laptop more like an oscilloscope-sized suitcase and weighing over 10 kg. Changed anything since then? Definitely changed. And for some time.

Inside Laptop
First, go through the components inside the notebook. Before we classify them according to cost and size, to navigate the configuration.

Processor
Today, you can watch the sunset single-core processors. Dual-core mobile chips are installed, even in the budget model, although still not all. A year or two, and they will take the market entirely. So far, sales there are mobile PCs based on the following CPU (central processing units):

AMD Mobile Sempron and Turion 64. Mobile Sempron come across less frequently. The cost of the Turion 64 is low enough to abandon the lowered prices analogues in his favor. The difference in performance between them is not very significant, but the Turion - it's all the same chip is a higher class. So if you have the opportunity, it is best to stay on the laptop based on it (of course, if you choose from budget models). It is also more preferable than the Celeron M, because it supports energy-saving technologies and, on average a little faster.

AMD Turion 64 X2. Budget dual-core processors. If you do not have enough money on the Core 2 Duo, then the Turion 64 X2 as a cheaper alternative - a very worthy choice. It should be noted that now on the market there are several versions of this CPU. Preferred to stay on the series models TK, as well as recent modifications of the TL. They are built on the core Tyler, manufactured on 65 nm process technology. This will reduce their thermal performance, as well as to raise the clock speed.

Intel Celeron M. Enough good processors that differ from the older Core Duo and Core 2 Duo lower FSB FSB, one of the core, as well as the inability to dynamically change their frequency depending on load. This last point is not the most favorable impact on battery life laptop. But the performance of data the CPU is quite high. Now available on the market Celeron M 400 series and 500. The first is based on the same core as the Core Duo, and the latter - Core 2 Duo. Celeron M 500, obviously, preferable.

Intel Core Duo. These processors are even already obsolete, but still can provide very high performance.Furthermore, their heat dissipation and power consumption is lower than the Core 2 Duo, and even these chips are cheaper. Today it is possible to find a mobile PC with a very "delicious" configuration and CPU Core Duo. Do not rely on the opinion that the new is always best. If you are not fighting for every second boot Windows and programs in it, the laptop based on the previous generation processor can be your best option to purchase.

Intel Core 2 Duo. Modern mobile flagship Intel. Today, there are two versions - with the system bus 667 and 800 MHz. Naturally, it is better to buy computers based on the latter. At the same clock speed, they will provide a higher speed, and the chipset in the laptop will be newer. In addition, the new Core 2 Duo supports a special feature Intel Dynamic Acceleration, which increases the frequency of one nucleus, if the second idle. This can be very useful when performing single-threaded applications. There are also varieties with 2 and 4 MB second-level cache. The first - a model of the entire series and T7100 T5000, refer to the second remaining. The difference in speed between these chips are not very significant, therefore, to worry about buying a mobile computer with a processor, is equipped with 4 MB L2-cache is not worth it.

Pentium M. Yes, the old Pentium M is still alive. Although a new laptop based on it are hard to find. On the other hand, if you do not fundamentally have two cores to their goals, Pentium M will provide very good performance, and its thermal performance is better than the budget Celeron M and the Mobile Sempron.

On anything from the above list? If you have enough funds, then the Core 2 Duo, otherwise the Core Duo. In the budget segment, a good choice Turion 64 X2. Single-core Celeron M and Mobile Sempronnot so good, although in terms of price they are very attractive.
