Multi-Threaded Efficiency

AMD FX: Energy Efficiency Compared To Eight Other CPUs
By , Achim Roos

The total run time of our threaded benchmarks is not as devastating to AMD's FX-8150 as the single-threaded collection. AMD is beaten by Intel's six-core Gulftown design (Core i7-980X), and it cannot hold off the Core i7-2600K. It's close to several other processors, though.

Taking a look at average power consumption, the FX-8150 finishes in last place. Even its predecessors were more energy efficient.

It's a bummer that this represents a best-case scenario for AMD, where its architecture's resources are best-utilized.

This isn't as bad as the single-threaded application benchmarks, though. And while the average power draw is high, the benchmark does not run for that long and the resulting total power consumption in watt-hours is quite low. With that said, Intel's processors offer better efficiency, regardless of the CPU model.
