GIGABYTE started as a research and development team and has since taken the lead in the world's motherboard and graphics accelerator markets. To truly reach out to all consumers, GIGABYTE further expanded its product portfolio to include more diverse digital products such as Notebook and desktop PCs, digital home appliances, networking servers, communications, mobile and handheld devices, servicing every facet of people's lives at home or at work. Motherboards are printed circuit boards containing PC microprocessors, memory devices, and other key chips. In addition to motherboards, the company's product menu features servers, graphics accelerators, thermal products (chassis and coolers), netbook and notebook computers, desktop PCs, wireless communications equipment, and mobile phones. Motherboards make up around three-quarters of the company's revenues.
