Intel Officially Unveiled the 2.8 GHz Core 2 Duo Merom

The high-end iMac is powered by an Intel 2.8 GHz Core 2 Duo Merom, a processor which did not officially exist till yesterday. The German website Heise identified its entry in Intel Core 2 Duo mobile CPU catalog: Core 2 Extreme X7900, with the corresponding price US$815 per unit for 1000 unit order...
The power consumption is of course proportional to the high clockspeed, 44W instead of 35W for lower models; but it does not seem to affect the silence of the new iMac 24" at work.
As all the Intel "Extreme" CPU, the multiplication coefficient of this processor should not be locked, so on a BIOS-equipped PC motherboard, one could easily push it to 3.0GHz and even more. On a Mac, we miss such overclocking tools, and despite a genial hack, the frequency will remain unchanged, even tough we would really enjoy to push it in its "Extreme limits".
