Audio and Video Encoding Performance

Below you get a look at the main screen CPU-Z screenshot to give you a look at the actual specifications of the unit that we will be testing further on below.

The ViewSonic VPC190 will be run through the standard AIO test regime here at TweakTown. This includes iTunes Encoding and Media Transcoding.

Please note that no 3DMark or game tests are included for our AIO reviews since they are not powerful enough to run the graphics intensive tests. All systems are tested "as is", which means operating systems and drivers can and do vary and some come pre-installed with applications that may or may not affect performance. Any anti-virus or security applications are disabled and uninstalled before any testing is started as they can affect test numbers.

For the iTunes encoding test I take the Stone Temple Pilots - Core CD album in MP3 format and encode it to AAC format using iTunes and time the results with a stopwatch.

All tests are performed with the system in High Performance mode with minimum CPU set to 100%.

As you can see in the chart above, the ViewSonic VPC190 is much slower in this benchmark than the Gateway ZX4800-06 I tested recently. I suspect that this will be the average score in the new AIO category for us with rigs running netbook hardware.

For the movie encoding test I take the Microsoft Magic of Flight VC-1 WMV video with six channel audio (1080p HD) and transcode it to XviD (1080p HD) with LAME MP3 two channel audio and a MP4 container using MediaCoder 0.7.3.4616 32-bit edition.

All tests are performed with the system in High Performance mode with minimum CPU set to 100%.

Again, the ViewSonic VPC190 was far behind the Gateway ZX4800-06. The ViewSonic VPC190 is certainly not the machine you would want to lean on for converting lots of video.
