It&#8217;s the <strong>equivalent of getting two microprocessors in one<\/strong>.<br \/>\nDual core technology refers to <strong>two individual microprocessors on a single die cast chip<\/strong>. This is essentially two computer processing units (CPUs) in one. The advantage of a dual core chip is that <strong>tasks can be carried out in parallel streams, decreasing processing time<\/strong>. This is referred to as thread-level parallelism (TLP).<br \/>\nTLP is also possible on motherboards that can accommodate two separate CPU dies. When TLP is accomplished in a single CPU through dual core technology, it is called chip-level multiprocessing (CLM).<br \/>\nIn dual core CPUs, each microprocessor generally has its <strong>own on-board cache, known as Level 1 (L1) cache<\/strong>. L1 cache significantly improves system performance, because it is much faster to access on-chip cache than to use random access memory (RAM). L1 cache is accessed at microprocessor speeds.<\/font><\/font><\/p>\n<p><font size=\"3\"><font face=\"Georgia\"><br \/>\nThe <strong>Intel\u00ae Core\u21222 Duo<\/strong> desktop processor delivers revolutionary dual-core performance and breakthrough <strong>processor energy efficiency<\/strong>.<br \/>\nBased on the revolutionary Intel\u00ae Core\u2122 Microarchitecture, the Intel Core 2 Duo processor has been developed for an increasingly <strong>multimedia-centered, high-definition world,<\/strong> and is designed to <strong>do more in less time<\/strong>.<br \/>\nIntel Core 2 Duo processors <strong>operate at lower frequencies while producing higher performance<\/strong> compared to today\u2019s higher frequency processors, thus enabling quieter and smaller desktop PCs.<\/font><\/font><\/p>\n<p><strong>Therefore we can conclude like this<\/strong>:<\/p>\n<p><u><strong>Core Duo<\/strong>                           vs                     <strong>Core 2 Duo<\/strong> <\/u><\/p>\n<p>2 Core in a Single chip                     2 Core in a single Chip<\/p>\n<p>32 &#8211; bit                                              64 &#8211; bit<\/p>\n<p>Consume more power                    Comparatively less<\/p>\n<p>2 MB L2 Cache                                4 MB L2 Cache<\/p>\n<p><u>First Generation                             2nd Generation <\/u><\/p>\n<p><em> I am sure there are more differences, and if you know any of them I request you to share it with us. <\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Intel's convention of naming its processor series is quite interesting.
