One of the most important features of a laptop is the laptop GHz performance.
At present, the laptop market is covered by three major manufacturers of processors: Intel, AMD and VIA. Of these, Intel, the largest and best known, is responsible for more than two thirds of total global sales.
The processors are mainly produced by Intel followed by AMD. VIA is in last place with only 0.1-0.4%. To be mentioned that to remain on the market, VIA has decided to focus on a specialized segment. It is the cheap processors (with low laptop GHz value) dedicated segment, with very low power consumption but low performance. Because laptops with VIA processors are rare outside of Asian countries, is not appropriate to insist on the brand.
It is almost a rule that laptop processors to be derived from the architecture of desktop processors. Therefore, when a manufacturer launches a new generation of desktop processors, a new generation of laptop processors will follow. The two lines of processors (desktop and laptop) will often share the same innovative technologies and manufacturing methods, the vast difference between them being the power consumption.
Unlike desktop processors, which generally dissipate over 95W of heat and consumes just about as much power a laptop processor dissipates about 35W of heat and consumes about 40W (maximum value). It is worth noting that to get this low, manufacturers reduce the laptop GHz and voltage, which translates into lower performance than desktop computers.
As an example, Intel i5 desktop processor (dual core) costs $ 294 *, has a frequency (speed) of 3.60 GHz and 75W consumption. A processor of the same type but made for laptops cost $ 332 *, has a frequency of 2.80 GHz and consumes about 35W. So the laptop GHz is always lower than desktop computers.
For ultra mobile laptops, for which battery life is a priority, manufacturers further reduced power consumption and laptop GHz. For example, a processor i7-680UM (dual core) at a price of $ 317 * consumes only 18W, but has a frequency of 1.33 GHz. The good thing is that most current applications will run smoothly on low laptop GHz. The debate about the essential features of a laptop reach consensus on two points: portability and performance. Therefore, to meet consumer needs, processor manufacturers offer their share in 4 categories: top class (games / graphics utility), class (most laptops), CULV (Ultra) and lower class (entry level, cheap laptops and notebooks).
Manufacturers generally will launch a new generation of processors every 12 months. Each generation is accompanied by a processor chip that is made by the same manufacturer and integrated on the motherboard of the laptop. This is the best time to upgrade your laptop GHz. This chipset manages the operation of all important components of the laptop / PC. The combination of chipset and processor is called platform.

The chipset is changing along with the generation of processors, such as a new generation processor will not work in a laptop that uses a previous generation processor. So if you want to upgrade your laptop GHz you will need to change the chipset too. Similarly, with few exceptions, an older generation processor will not work in a laptop with a chipset from a newer generation.
