The Core Components of a Centrino Mobile Technology Notebook

We have probably heard all about the Intel Centrino Mobile Technology. But what makes a Centrino, well, a Centrino? In this page, we'll show and explain to you the technical aspects of the Centrino Mobile Technology - which is essentially made up of three core components. They are the Pentium-M processor, the 855 Chipset, and last but not least the Intel PRO/Wireless 2100. What are they, and in what ways do they make Centrino tick? We explain.

Intel Pentium-M Processor
A key component of the Intel Centrino Mobile Technology and a member of the Intel 855 Chipset family, the Pentium-M is also the newest processor built from ground up by Intel. Starting with speeds from 1.3GHz and up to 1.6GHz, the Pentium-M is designed to go the extra mile with its advanced power distribution intelligence. This main characteristic of the processor allows it to prioritize its power needs, as well as increasing battery life by shutting down any components not in use. In order to do that, there are various technologies within the processor that helps to make it as energy-efficient as possible.

For one, there is the built-in Enhanced Intel SpeedStep power-management technology, which is a similar feature found in the Pentium III-M and Pentium4-M processors. What SpeedStep does is to lower the clockspeed of the processor (and thus consuming less energy) when it detects that the notebook is running on batteries. Another important feature in the Pentium-M is its power-optimized 400MHz processor system bus, where it will remain powered down until it senses incoming data from the chipset. In this way, every bit of power is saved, as the processor would tend to consume less power if part of it remains powered down when not in used. The Pentium-M doesn't skimp on performance that helps to speed up your applications either - with an impressive 1MB on-die L2 cache and the already-mentioned 400MHz system bus.

With the Intel Centrino Mobile Technology's foundation of mobility in notebooks, the Pentium-M is designed specifically for the thinnest and lightest notebooks. All these are done without sacrificing performance and battery life.
