iTunes Test
We ripped a 13:56 minute AIFF music sample to the hard drive. Then we used iTunes to encode it into AAC (default settings).
Blue: The time taken for the conversion in seconds. Red: x ratio (the number of times the rip could be performed in a time period). Yellow: efficiency coefficient of the processor according to frequency; this coefficient permits the judgement of the architecture quality independent from the frequency.
It should be noted that iTunes does not particularly have multiprocessor support. In fact, it only utilises one core for the encoding while delegating the remaining tasks and system management to the other core.
The efficiency coefficient shows that the Core 2 Duo is around 20% faster in these tasks than the Core Duo at the same frequency.
Note that the T7600's 4 Mb cache does not help its efficiency.
You can see that a 2.33 GHz Core 2 Duo is more than two time faster than a 1.5 GHz Core Solo in encoding.
