Video and Audio Encoding

These diagrams don't have anything new to tell us. The Core 2 Duo E4300 on the Allendale core is about 4-5% slower than the Core 2 Duo E6300 at encoding video and 2% slower at encoding audio.

The Allendale-based CPU shows good performance scalability depending on its frequency. When overclocked by 90%, the Core 2 Duo E4300 shows a performance growth of 75-90%.

Image and Video Editing

There's no difference in image and video editing applications: like in the other benchmarks, the Core 2 Duo E4300 overclocked to 3.42GHz is considerably faster than the Core 2 Extreme X6800. This confirms our point that the amount of L2 cache memory doesn't influence performance of these CPUs much.
