<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "> Hopefully this will help shed some light - a long tome ago Apple broke up with PowerPC because of whatever and teamed with Intel. This may be one of the reasons: The processor, labeled the X7900 by Intel, is a sibling to the X7800, a 2.6GHz CPU designed for mobile computers that Intel said in its launch "the world's fastest-performing mobile processor". The X7900 (iMac 2.8MHz) wasn't expected until later this year, but Apple apparently with Intel moved quickly with the new chips.<div>Both X7800 and X7900 processors use socket P (Intel's Santa Rosa notebook platform). Apple uses chips normally slated for notebooks in the iMac, reflecting their laptop-like design. The higher temperatures of other types of desktop chips would give the iMac heat problems, or require larger and louder fans.</div><div>By the way, thanks - you just helped me think why the wireless keyboard is so like the MacBook family. </div><div>Anyway this is all so new that the Intel website is not yet updated with this chip info.</div><div><br class="webkit-block-placeholder"></div><div>HTH,</div><div>C<br><div><br></div><div><div><div> <div><div><div>On Aug 9, 2007, at 7:36 AM, Jeff Johnson wrote:</div><div><br class="webkit-block-placeholder"></div><blockquote type="cite"><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="3" style="font: 12.0px Helvetica">I agree.
