1. Portable notebook CPU main feature CPU is the core of the notebook, is the key to improve overall performance. The laptop emphasizes mobile performance, volume and weight into its important performance indicators, especially in the laptop, super light, super light Today, today, today's performance of the CPU of the laptop puts forward strict requirements. Due to the natural characteristics of the notebook, the integration of the entire laptop is higher, the heat dissipation of the portable system is more difficult than the desktop, but the processor also The proper temperature must be maintained, which has highly required heat dissipation, so the CPU of the laptop must be smaller, and it does not degrade the performance and stability of the entire laptop due to heat dissipation problems. Similarly, the CPU has a small power consumption and more helps to maintain a longer usage time. Affected by shape, the new notebook CPU must maintain a small volume while maintaining high performance and speed. Small and light portable computers need special features to maintain its best performance. In order to solve the above problems, the notebook CPU is mainly satisfied with the requirements of the requirements: l Low power consumption: reduce the operating voltage, reduce power consumption, to improve longer working hours L high-density foot pack: reduce the volume, provide more features , L Reduce heat consumption and improve the efficacy, reducing heat generation, in order to seek stability of the system under high speed operation 2, micron manufacturing process CPU is a heavyweight. The faster it, the greater the power consumption, the harder the heat dissipation problem. It is well known that heat dissipation problems will result in serious decline in notebook performance, and system reliability issues, and even affect other parts of service. Again, laptops that move the office as the original intention, there are more requirements than desktop computers in some ways. The most basic problem is: How to make the machine's working hours, users do not have to change the battery frequently? The expansion battery capacity is one of the solutions, and as the CPU of the energy consumption, it is a need for smaller power and power consumption. In addition, driven by their own characteristics, laptops will have stricter requirements for CPUs more stringent than desktop CPUs. Taking heat dissipation problems, Intel's desktop computer CPU package only withs 20 degrees Celsius temperature test can pass quality inspection, and notebook-specific CPU packages must do 100 degrees Celsius due to their own reasons; at the same time, desktop is in some Some features have some features not only unable to implement in the notebook, but also affect the stability of the computer system. Based on the above factors, it directly leads to the birth of a notebook-specific CPU. It seems to be a small step from the desktop to the laptop, and for the development of micron technology and computer technology, it is not ignored. In 1993, the first notebook dedicated CPU Mobile 386SL launched in Intel, ended the history of desktop computer CPU, a desktop computer and laptop market. In 1994, Intel's Mobile 486SL enhanced version of the 0.6 micron process was more hailed as "in the market and technology to achieve a win-win notebook special CPU", and the success of notebook dedicated Pentinum is largely benefited from its adoption. 0.5 microns production process, the performance of the performance is greatly improved ..... Overall, the micron manufacturing process makes the notebook dedicated CPU have rapidly develop. With the development of society, users have put forward lighter, thinner and smaller requirements for notebooks, which is undoubtedly another challenge to micron manufacturing processes, but to some extent, micro-production process is more excellent. Due to the use of 0.35 micron manufacturing process, notebook special MMX (multi-Pentium) CPU will successfully take the Pentinum of 0.5 micron manufacturing process with its performance, to today, the emergence of 0.25 micron manufacturing process The birth (0.25 micron concept is 1/400 of a hair diameter).
