The history of Celeron M processor starts about seven years ago, when Intel, a world-leading manufacturer of central processor units for personal computers, presented its first line of low -cost economic processors with the brand name Celeron. These processors were produced in parallel with the Pentium CPUs with the aim to expand the market of low-cost personal computers. The first lines of the Celeron processors had no Level 2 cash memory, which allowed Intel to decrease significantly the price of the chip in comparison with the full-stuffed Pentium. However, this was the problem of the first Celeron processors; the absolute absence of the L2 memory caused extremely low efficiency of that processor, resulting in small popularity of them on the market. Later, Intel decided to equip its Celeron chips with the L2 memory, however, the volume was usually half of what the Pentium chip offered. Nevertheless, these appeared to be enough for the most of applications, and Celeron, being a more affordable chip than Pentium, became one of the most popular and widely spread processors for home computers, small and medium companies.

The rapid development of small sized portable laptop computers or notebooks made new demands to the central processors, requesting them to be optimized for mobile applications. It concerns, first of all, the power consumption of chips and their heat generation. As a result of new trends on the IT market, Intel developed and brought to the market the Pentium M and Celeron M chips, where "M" stands for "Mobile", indicating the chip, targeted at the notebooks.

Nowadays, the Intel Celeron M processor is a whole family of modern mobile processors, providing high efficiency and low power consumption with a very reasonable price. Now, Intel offers fourteen models of the Celeron M chips, featuring the clock speed from 1.2 to 1.6 GHz. All these processors are equipped with the L2 memory cash, which is either one Mb or five hundred and twelve Kb. The key feature of all the Celeron M chips is their high optimization for the mobile devices needs. The miniature ninety nm architecture provides a space saving feature, thus, allowing to produce extra thin and light notebooks. The central processors are among the major consumers of electric power within the computer system; that is the reason why the Intel developers made their Celeron M processor to consume as little power as possible, resulting in longer time of independent work of notebooks without battery recharging.

There is no doubt that Intel will improve and enhance its Celeron M chips. According to the company latest announcements, Intel will move Celeron M processors from ninety nm into the sixty-five nm architecture in 2006, which will surely improve the mobility of the chips. At the same time, the processor giant will stop in the near future the production of one - one point three GHz chips in favor of more effective and quick processors with a higher speed. Obviously, the next generations of Celeron and its elder brother Pentium will only enforce the Intel leading position on the world market of the central processor units.
