Real Applications
Next we tested the notebooks in a few real-life applications.
The Core 2 Duo T7500 finds it easy to encode video with the DivX 6.7 codec.
MP3 encoding is an easy task for the notebook’s high-frequency CPU as well.
This test script from Adobe Photoshop emulates the processing of five 5-megapixel photographs. The notebook delivers high performance here, too. Note that its performance differs noticeably between the two cores.
The U3S shows its best again thanks to the high CPU frequency. The threefold performance hit in the battery mode is due to the aggressive power-saving measures.
Data compression is not a problem for a top-performance CPU that could use a large amount of system memory.
In the next test a script is used that prepares a video clip for uploading to YouTube. The clip was made out of four video fragments captured from a digital camera. The Core 2 Duo T7500 copes with the job easily. The notebook’s performance is much lower in the battery mode, though.
The results of the final rendering test are proportional to the CPU frequency.
