[QUOTE="leomax, post: 272152, member: 3817"] Non-native dual core processor, Classic example is a Smithfield,Pentium D 8xx,which consist of two independent Prescott cores combined on a single silicon die with an arbiter to share the FSB. [IMG]http://xs414.xs.to/xs414/07130/des2.gif[/IMG] It can be a MCM (Multi chip module),Classic example is a presler aka Pentium D 9xx,in this case two cedar mills (6xx P4) are bolted together and packaged,there are two separate dice . Kentsfield uses the same technique for quad core . In both cases L2 cache is not shared,Each die can be considered as a single cpu,so there is only a 800MT/s FSB (1066MT/s in EE) to feed data to both core's,so there will be a performance hit in application that use coz each core gets half each. [IMG]http://xs414.xs.to/xs414/07130/intel-core2duo-diagram-440x370.jpg[/IMG] Couldnt get a better pic,sorry :P L2 is shared in case of core architectures,but there are two separate execution cores,both core can communicate with each other without going out of processor.. Athlon X2 is a bit different [url]http://xs414.xs.to/xs414/07130/scheme.jpg[/url] [url=http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_9485_13041%5E13043,00.html]Key Architectural Features[/url] [/QUOTE]
