- Accessory Port Testing
Ports to which an external storage device can be connected to are tested using HD Tune Pro to obtain their maximum, minimum and average read and write speeds. USB 2.0, USB 3.0 and eSATA ports are tested using a Corsair Neutron GTX 240GB SSD that is capable of saturating the theoretical bandwidth available.
The Corsair Neutron GTX is housed inside an Icy Dock external enclosure which features a SATA I/II/III to USB 3.0 and eSATA converter.
- Gaming Tests
Battlefield 3 is run at 1920 x 1080 resolution with the graphics preset set to "Ultra." The test is ran three times due to higher variability than the other benchmarks. FRAPS is used to record 60 seconds worth of FPS data and recording starts when the character first picks up the gun at the start of the campaign and usually finishes shortly after the train explosion. The game is played in a similar manner each time.
3DMark Vantage is ran on the Performance preset to get a feel for how the computer would manage gaming. The CPU, GPU and combined scores are reported. A higher overall score is the best and a high GPU or CPU score shows particular prowess with tasks that use that part of the computer.
3DMark 11 is run on the Performance preset and the Physics, GPU and combined scores are reported. This test is only run if the system supports DirectX 11. A higher overall score is the target, though a high individual result shows prowess in a particular area.
3DMark is the latest benchmark by Futuremark. The Cloud Gate test is ran with all of the default settings and the score, GPU score, and physics score are all recorded in the chart. The Cloud Gate test is intended to be run on home desktops and notebooks.
- System Tests
PCMark 7 is run to get an overall idea of how the system performs as a whole. It tests all aspects of the PC and puts a score on how well it performs overall. In this test, a low scoring area can affect the overall score, so it's important to read the analysis. A higher score is better.
MobileMark 2012 is another test run to get a feeling for the system performance taken as a whole. MobileMark 2012 uses real-world applications as part of the benchmark. We use the Office Productivity suite which includes applications like Adobe Acrobat and Microsoft Word. The test also reports battery life as all tests are run on battery. Higher is better for both results.
CrystalDiskMark is run to put a number on how well the system hard disk drive / SSD runs. It measures five different metrics, of which higher is better for all. The higher the numbers, the snappier the operating system will feel, especially if the "4K" number is high, as most operating system files are small files.
- Battery Life
PowerMark is used to measure battery life of the system when set to "Balanced" and "Performance" power plans. This test simulates several different activities, but uses custom built applications.
