What kind of Intel Core 2 Duo has the iMac 20" and 24" ?

Question

Hi,
I wanted to compare the Intel Core 2 Duo processors from the iMac with the ones available for Dell pcs.
I noticed that there are many kinds of Intel Core 2 Duo processors: E6400, E6600, etc.
I tried to search on apple.com if they had more specific information about the kind of Core 2 Duo but couldn't find it anywhere.
Can anybody tell me ?
Cheers! cj.

Answer 1

Apple uses the mobile version of Core 2 Duo in the iMacs. They only use the 1.83 to 2.33 GHz versions.
This is from the Wikipedia;
Merom
Merom, the first mobile version of the Core 2, was officially released on July 27, 2006 but quietly began shipping to PC manufacturers in mid-July alongside Conroe.[5][6] Merom is Intel's premier line of mobile processors, with largely the same features as Conroe but with more emphasis on low power consumption to enhance notebook battery life. Intel has claimed that Merom will provide 20% more performance yet maintain the same battery life as the Yonah-based Core Duo. Merom will be the first Intel mobile processor to feature EM64T 64-bit extensions.
Intel has stated that the first version of Merom is drop-in compatible with the current Core Duo platform, requiring at most a BIOS update. It has the same thermal envelope and the same 667 MT/s bus rate.[7]
The Merom processors are labeled as the "T5x00" and "T7x00" Core 2 Duo models, with the T5200 clocked at 1.60 GHz, the T5500 clocked at 1.66 GHz, the T5600 clocked at 1.83 GHz, the T7200 clocked at 2.0 GHz, the T7400 clocked at 2.16 GHz, and the T7600 clocked at 2.33 GHz. The T5x00 models come with 2 MB of shared L2 cache, and the T7x00 models come with 4 MB of shared L2 cache.
