Performance in Real Applications
We also benchmarked the notebooks in a few real-life applications.
The Penryn core is better at encoding video with the DivX 6.7 codec.
The same goes for encoding of MP3 files. The Merom core is somewhat slower.
The test script for Photoshop CS2 performs a typical processing of five 5-megapixel photos. The notebooks are roughly similar in this test.
Strangely enough, the more advanced CPU is slower in the Excel-based script. The Penryn is not so much better than the older core after all.
The Core 2 Duo T7700 and T8300 processors take about the same time to archive a folder with files.
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 Penryn core is a tiny bit faster.
The Penryn core wins the final rendering test, probably due to its large cache.
