Benchmark Results: Efficiency
Six cores are decidedly fastest at completing our efficiency workload.
Interestingly, average power consumption was lower on five cores than on four during our workload.
Total power used scales well. It's obvious that the many-core configurations require less total power to complete our workload.
As a result, the higher active core counts deliver better performance per watt.
