Our efficiency workload consists of most of the benchmarks you found on the test setup page. We split into single-threaded and multi-threaded workloads to get a better look at what you’ll see in real life if you decide to overclock your Phenom II X6. This single-threaded section includes Adobe Acrobat, iTunes, Lame, and WinZip.
It’s interesting to see that the total power used to complete the full single-threaded workload is actually lower on the overclocked processors. Performance and power consumption scale linearly, as you can see by total power used being identical on all three overclocks.
