Performance and total cost of ownership (TCO) are key optimization metrics in large-scale data centers. According to these metrics, data centers designed with conventional server processors are inefficient. Recently introduced processors based on low-power cores can improve both throughput and energy efficiency compared to conventional server chips. However, a specialized Scale-Out Processor (SOP) architecture maximizes on-chip computing density to deliver the highest performance per TCO and performance per watt at the data-center level.
