In the past few days, I have helped students read their laptops and learned a lot about them. At the same time, I am deeply impressed by the differences between the notebook market and the desktop market, not to mention the complexity and confusion of various brand series and models (just an IBM t42 series has dozens of models, each model is followed by three numbers/letters, so that outsiders do not know the so-called), just say that the commonplace of the company, Pentium M, sai Yang m, as well as the current Sonoma, Dothan and so on, this is enough to make buyers feel discouraged and at a loss. Now, we will give a brief introduction to the online materials for literacy purposes only.
When the Centrino platform was released, three major hardware components were Pentium m cpu (Banias core), 855 series chipset, and Intel Wireless/Pro 2100 3B wireless network adapter (802.11b. It can be seen that the Pentium M (PM) is only a component of the Centrino, which is why many laptops are the CPU of the PM instead of the Centrino.
The three major hardware components of the Sonoma platform are the Dothan core Pentium m cpu, 915 series chipset, and Intel Wireless/Pro 2200bg/2915abg wireless network card. Using the 915 system chipset is a major leap of the Sonoma platform. Similarly, many laptops do not comply with the Sonoma requirements, nor are they referred to as the Company's. Even if they use the Dothan core CPU. It should be noted that Intel itself does not have the official statement of the Chinese version 2, which is just a name on the Internet.
In this way, we can see that the Pentium M includes the CPU of the original Banias core and the cpu Of the current Dothan core. The obvious difference is that L2 is 1 m, while L2 is 2 m. Of course, there are also differences in technology and power consumption. If it is the Dothan core Pentium m cpu, it is generally pointed out. Sai Yang M is a simplified version of the CPU with the same core as the Pentium M, mainly because the second-level cache is only 512 K and does not support speedstep, which is significantly different from the performance of the Pentium M.
In this way, we will clarify the relationships between those concepts: Sonoma> Centrino; Pentium M (Dothan)> Pentium M (Banias)> sai Yang M. Other Processors are not mentioned here.
