With the advancing of Intel and AMD, VIA C7-M define its focus on UMPC market. C7-M has the advantage on its power and size, making it suitable for power-limited UMPC instead of performance based Intel Pentium M ULV and AMD Turion ULV. C7-M 779 (1GHz/128KB L2/400MHz FSB) for example, it consume at a maximum of 3.5W, average on 0.75W, and 0.25W only in C4 mode. Besides, with the low profile VIA C7-M, both the heat sink and battery can be minimized. Together with integrated chipset VX700, the total size with CPU is only 1666 mm sq. compared with 2915 mm sq. of Intel Pentium-M ULV + 915GMS + ICH6-M. The smaller size helps VIA C7-M based UMPC be more portable and small.
