Performance is the main concern of laptop buyers

Survey on some Vietnamese technology forums such as VOZ, Amtech and HHVN shows that most consumers consider processing power, power consumption and price are the three things they most consider when deciding to buy the device. laptop.

Regarding the processing capability of laptops (ranked by the majority of participants in the above mentioned forums), the chips are getting smaller and smaller to meet the requirements of compact design for Mobile computing devices, while the power is constantly being improved to enforce the number of processing tasks with many types of high-capacity content.

This is due to the continuous development of semiconductor technology based on Moore's Law, which typically represents a transition to a 45-nanometer (nm) microprocessor set up by Intel last November. With this achievement, now each microprocessor is only about the size of a stamp but contains up to 820 million transistors. Intel's 45 nm Penryn line of chips are the first to use metal gate transistors, increasing performance, limiting leaks compared to silicon port technology.

" If we use transistors that are similar to those of 15-20 years ago, now every microprocessor must be as big as a two-story building, " Intel's Bill Kircos said.

Enhancing the power of microprocessors and shrinking their size is not all that laptop users expect. The need for mobile computing with increasingly complex tasks means that power consumption is not small. Therefore, new semiconductor chip technologies are forced to find ways to solve this problem. This is also the third most important factor in the decision to buy laptops by survey participants on forums.

According to Stephen Smith, Intel's director of digital business, the most power-hungry 45 nm chip system consumes no more than 120 watts. Laptops released in the first quarter of 2008 show a consumption of only 25 watts, compared to the laptop's 35 watts using the current 65 nm technology, thus contributing significantly to prolonging laptop battery life. .

In parallel with limiting power consumption, 45 nm chips enhance clock and cache clock to improve processing speed compared to 65 nm with at least 40% - 60% efficiency handling photos and videos .

When the basic elements mentioned above are attractive enough, the price will be the most interesting issue left to convince people to spend money on laptops, especially for a market like Vietnam, where cost factors for the majority of consumers are always sensitive. More than 75% of participants surveyed on Amtech forum and nearly 50% of HHVN ranked in second place among the factors affecting their decision to buy laptops. In fact, the price of most computer items is always in a constant downward trend, while the configuration is getting higher.

At Vietnam IT and Consumer Electronics Show 2008 (VN Computer Electronics Expo 2008) held in Ho Chi Minh City. Ho Chi Minh City from July 16 to July 19 this year, the world's largest chip maker Intel is expected to launch domestic consumers a breakthrough mobile processor technology, promising to create New push for the laptop market in the world as well as in Vietnam.
