Today, notebook PC customers are frequently presented with a single battery life benchmarking score that is
gathered using light workloads and a relatively idle CPU. This single score does not take into account how a
notebook PC battery may perform when the battery is used in a more “active” state, such as when a notebook
PC is running sophisticated graphics or performing complex computations.
There is currently no single benchmark test available for notebook battery life that accurately refl ects reallife
usage patterns. Adding data gathered using a heavier workload and an active CPU to the currently used
benchmark score can provide a more realistic gauge of battery life in notebook PCs—and this additional data is easily provided by existing mainstream benchmarking tests.
AMD published a paper on this issue and the goal of this white paper is to encourage a more transparent discussion around battery life benchmarking
for notebook PCs. By evaluating benchmarking results from multiple tests, such as the BAPCo® MobileMark®
2007 test and the Futuremark® 3DMark®06 test, it is possible to get a more balanced view, incorporating both
“idle” and “active” system states. This paper provides step-by-step guidance for running the two benchmarks so that notebook PC customers can obtain more realistic battery life estimates.
