Energy consumption between different CPU models started to be a key point of interest in the Sandy Bridge era due to enormous gains in the perf/Watt metrics which were normally the province of GPUs along. We analyse two crucial figures: first of all idle tests where the system is cold booted into Windows and no additional applications are executed - the watts are noted on the external energy monitor we use; second the system is loaded with 3DMark FireStrike - watts are again monitored for the duration of the test and the highest rated wattage result is then noted down. Below are the results of this energy test.
