- Simpler cores are better performing
- Add more cores asn cache, memory interconnection and IO is a big design issue

This isn't because Intel sprinkles magical performance/watt pixie dust on Atom—it's because high performance/watt ratios for individual chips are much easier to achieve at Atom-scale than at Xeon-scale, owing to the much larger amount of system-related complexity and overhead that goes with the Xeon's much higher level of integration and performance</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://arstechnica.com/business/news/2009/09/arm-attacks-atom-with-2ghz-a9-can-servers-be-far-behind.ars?utm_source=rss&utm_medium=rss&utm_campaign=rss">It's also the case that for raw performance, interconnects and system architecture issues matter a great deal</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/A153D06C-8C9C-4F97-8A56-CC3D170DD13B/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
