Notebook processor is typically a lower powered processor, than those in comparable desktop computers,although some manufacturers use the technology same as their desktop processors to give laptops a performance edge. Processors designed for laptop generally consume less power and are thus exposed to cooler than desktop processors. This is important because the battery would last a long time. Desktop computers usually have a huge heat sinks and fans to cool, but it is difficult for the small things in notebook computers, and fans of notebook battery drain quickly.
Thermal Design Power or TDP. This gives the maximum amount of power that the processor cooling solution. Not always will dissipate the energy, but generally, if you want the CPU cooler, go to the lowest TDP get.Some users say that Celeron processors are not good to be used for intensive applications such as 3D games and other works but are very suitable for the average home user who just wants to just surf the Internet and browsing.
Functional properties distinct notebook-processors which include a number of things like, the cache and bus speeds and speed chip it contains. Mainstream processors are moving towards the two nuclei.
You can still use single core processors today, but there is better performer processor from Intel i.e dual-core, even if they are not large. The cache and the bus speed determines how fast the processor communicates . In addition to the characteristics of raw power, different cores have different options. For a good understanding of the performance you need to look professional or benchmarks for comparison with models of laptops. It is often difficult to do with laptops, because it is so easy to compensate for other parts of the test setup.
If you want the best performance, Intel is currently rules with the latest Core 2 Duo processors.With that said, if you want to negotiate, you can purchase a laptop with an older chip, Intel or AMD chip. For notebook users performance is usually not a big problem. If you want your notebook as your primary computer, and you have a number of multimedia and gaming application to be used then go for Dual Core Processors
Each manufacturer has there own dual core type processor – Core Duo & Duo 2 for Intel and Athlon 64 x 2 and Turion x 2 for AMD
Single Core processors
Intel = Centrino or Pentium 4
AMD = Athlon & Turion
It all depends on your budget
