Benchmark Results: Efficiency
The total runtime tells us how long the systems took to complete our full efficiency workload, including most of the applications mentioned previously. Clearly, the difference between one, two, and four cores is significant, while adding cores five and six don't yield the same performance jumps. This is very applicable to real life and typical applications.
The average power consumption during this efficiency run increases with every core we switch on, but look at how the bars create a curve that flattens out. Average power may increase, but so does performance, and probably to a larger extent.
These results are similar to what we found on our AMD system. The total power required to complete our efficiency workload is lowest with a maximum number of cores.
These results clearly show how performance increases significantly with additional cores while power consumption increases more moderately. If we relate performance to power used, we get confirmation that 5- and 6-core operation is most efficient.
