I understand that you want information about the power consumption of the Intel® Xeon® Processor E3-1245 v6 and the Intel® Xeon® Processor E5-2630, let me help you with this.
I regret to inform you that the power consumption will depend of the features of each processor (software) and the hardware you are using, For instance, the processor integrates Enhanced speed step technology, this will help reducing power consumption. Please check this info “Enhanced Intel SpeedStep® Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep® Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep® Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.”
Hope it helps.
