With the listing of Intel Core 2 Duo processors, the time to determine performance at a frequency level is over. Then came the age of the king of efficiency. Core 2 dual-core processor efficiency increased 40% and energy consumption decreased by 40%, which makes the whole machine power consumption greatly reduced, which is also the current trend of energy-saving, heat dissipation becomes no longer the most important thing, then, the miniaturization of the chassis, portability will become the mainstream trend of the future. The latest Intel roadmap shows that Intel will also aggressively promote the SFF (Small Form Factor) small chassis. It can be imagined that the future of the chassis, not only portable, but also more humane, more personalized, chassis as a computer hardware carrier will eventually and other household appliances as a part of home decoration.
