Its been quite some time since the Core Duo processor was released. Then the Core 2 Duo came out which brought about decent increases in performances ranging from ~10-30% if I am not wrong. Then recently Santa Rosa rolled out bringing about slight performance increases. The Core Duo was releases in January 2005 and now it is August 2007. Most probably we will see new processors in January next year too. So since two years we have seen a modest increase in processor performances, nothing too great. Will Intel's Penryn bring about something similar? So that if I buy a Penryn computer, after say 2 years I will still feel happy about my computers performance? I mean I wouldnt mind buying a Core Duo even today. The Core Duo was a significant upgrade over the Pentium line up. So do you expect Penryn to be a significant upgrade over Core 2 Duo?
