Testbed device listing.
If available, the latest motherboard BIOS is installed prior to testing. Certain services/features
like Indexing, Superfetch, System Restore, and Windows Defender are disabled
to prevent them from causing spikes in CPU/HDD usage. We also make note if energy
saving features like Cool'n'Quiet/SpeedStep or S3 suspend-to-RAM do not function
properly. If a WiFi adapter is present, it is disabled unless the system lacks wired ethernet.
Our main test procedure is designed to determine the overall system power consumption
at various states (measured using a Seasonic Power Angel). To stress the CPU, we
use either Prime95 (large FFTs setting) or CPUBurn depending on which produces higher system power consumption. To stress the IGP, we use FurMark, an OpenGL benchmarking and stability testing utility.
Finally, storage subsystems are tested briefly using CrystalDiskMark (1000 MB of 0x00 fill test data) and a Kingston HyperX 3K 120GB solid state drive. For USB and eSATA we use an external eSATA/USB 3.0 dock to connect the drive.
