Software and Measurement/Analysis Tools:
If available, the latest 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
Our test is a simple one, determine the overall AC power consumption, noise level, and heat output of the product
at various states. To stress the CPU, we
use either Prime95 (large FFTs setting) or CPUBurn depending on which produces
higher system power consumption. To stress the GPU, we use FurMark, an OpenGL
benchmarking and stability testing utility.
Storage devices and subsystems are also 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.
