This next announcement from ECS highlights the birth of two new "Mobile on Desktop" motherboards which both feature the ability to use Intel's Core Duo CPUs via the residing mPGA479M socket, thus providing quiet efficient computing in a desktop environment without compromising performance.
Both the Intel 975X chipset-based PF23 motherboard and the Intel 945GT chipset-based ECS 945GT-M motherboard are covered in more detail via the supporting PR here folks.
The Intel 975X chipset-based PF23 motherboard and the Intel 945GT chipset-based ECS 945GT-M motherboard both feature socket mPGA479M which supports the Intel Core Duo CPU, Intel's first 65nm dual-core mobile-optimised processor. This allows them to offer the lightening fast performance of a desktop with the cool, quiet operations of a notebook. A combination which provides stellar performance with reduced power consumption, improving the performance/thermal dissipation ratio which also leads to quieter fan operation and less noise.
