Serial ATA is to replace parallel ATA with the compatibility with existing operating systems and drivers, adding performance headroom for years to come. AOpen i865Gm-l Motherboard reduces voltage and pin count requirements and can be implemented with thin and easy to route cables. Moreover, Serial ATA provides you an even faster transfer rate of 150 Mbytes/second; Hyper-Threading technology is an innovative design from Intel that enables multi-threaded software applications to process threads in parallel within each processor resulting in increased utilization of processor execution resources. To make it short, it is to place two logical processors into a single CPU die.
