THE BENCHMARK TESTS WE USED
Futuremark PCMark 7 1.0.4
Futuremark’s PCMark 7 includes seven PC tests for Windows 7, combining more
than 25 individual workloads covering storage, computation, image and video
manipulation, Web browsing, and gaming. Specifically designed to cover the full range
of PC hardware from netbooks and tablets to notebooks and desktops, PCMark 7 offers
complete PC performance testing for Windows 7 for home and business use. For more
information on this benchmark, see http://www.pcmark.com/benchmarks/pcmark7/
PassMark DiskMark
The DiskMark component of PassMark’s Performance Test measures data
transfer speed when reading or writing data both sequentially and randomly to one or
more disks. Many factors affect this speed, and the Advanced Disk Drive Test allows the
user to vary most of these factors and compare the results. For more information on
this benchmark, see http://www.passmark.com/products/pt.htm.
