Wikipedia is a reasonable place (although not exhaustive) to learn about this technology.<br />http://en.wikipedia.org/wiki/Multichip_module<br /><br />Typically, vendors like Intel will mention when a CPU is a multi-chip module. For example, this forward looking article was describing the (future) Nahalem family members, some of which were not single-die CPU's.<br /><br />http://www.techradar.com/news/computing-components/graphics-cards/idf-not-all-intel-nehalem-cpus-single-die-147908<br />"Following Intel's eight-core Nehalem CPU announcement at IDF, Tech.co.uk can exclusively reveal that not all members of the new 45nm processor family will be based on a single-die design."<br />...<br />"Nehalem processors with integrated graphics will actually be built using two separate chips or dies packed into a single processor package. One die will contain the processing cores, the other the memory controller and integrated graphics core."<br />...<br />"For now, it's not known what impact the multi-chip approach might have on performance. But it will give Intel more manufacturing flexibility and perhaps allow it to support new memory technologies more rapidly. Instead of requiring a respin of a monolithic single-die CPU"<br /><br />Another example announcement, note the "dual-die" vs "native" language:<br />http://brightsideofnews.com/news/2009/4/16/intel-says-no-to-28nm2c-focuses-on-22nm-ivy-bridgehaswell--larrabee.aspx<br />"Nehalem's die-shrink family is called Westmere and is consisted out of at least four chips: dual-core CPU [plus dual-core CPU+GPU], native quad-core, native octal-core and possibly a dual-die hex-core"<br /><br />The question about whether the Intel 5500 series is a MCM or a single die comes down to what Intel states (since we can't really open up the CPU package, nondestructively, and see.) The 5500 appears to be a single die:<br />https://www.lemcomputers.com/store23/catalog/article_info.php?articles_id=1<br />"MONOLITHIC QUAD-CORE.<br />The Xeon 5500-series represents Intel’s first quad-core processor built on a single die. As a result, each core gets a smaller L2 cache and all four cores now share a large L3."Davidhttps://www.blogger.com/profile/00490096261085972137noreply@blogger.comtag:blogger.com,1999:blog-1088547107592909501.post-79274729064935220292009-05-29T16:16:31.708-04:002009-05-29T16:16:31.708-04:00Very interesting indeed.

It seems as if most people are interpreting the "multi-chip module" listed in the Oracle verbage to equiate to cores. Also, where can I find documentation on the 55xx series processer that confirms it is not using MCM technology?Tedwardhttps://www.blogger.com/profile/16735040260691579368noreply@blogger.com
