Intel QuickPath Interconnect Technology (QPI)

In this our part , get come to that , prevent arrive at in about [ story ] of , Intel Quickpath Interconnect Technology or that call briefly that , QPI , that vacate , for the principle works of way god takes to send speed tall data at is known that , QPI , the part in today the thing that us has will coming to will repeat that is in about [ story ] of with regard to , way , Intel , have way expansion or group QPI aforementioned this compound come to again one the group will originally from to have to come to one just the group on CPU in species , Bloomfield , but with Gulftown in today it has will to come to two all the group together , and we come to see that , the reason that must have the expansion comes in to are two that group because , what , or because , when CPU there is the axle evaluates more and more , then necessary to must have the way in taking sends wide data goes up with , in fact already will ? that we come to follow see [ praise ] the answer ( yes sir )

For the way takes to send the data that the name that , QPI , this at have to have the expansion comes in to are two that group because , way , intel , by oneself , have planning will to give CPU , in species , Gulftown or Westmere 6 core , this have various usabilities more and more , in this place will mean the character of the lead will go to is usable to can choose can use both of in Pat the form , Desktop , or , Pat the form , Workstation , and , Server , in principle already that having comes to of QPI two group amount will see and is usable effectively when , there is the usability on Pat the form , Workstation or Server , more than , because , in Pat the will form aforementioned this like to to have the usability in the format of , Multi-CPU or there is using CPU , one more than , by the group QPI at compound come to again one the group is will the way for use in transmitting data between CPU , together by oneself


In case of , there is using CPU two amount at the same time , the part in one again the group , will the way for use to take send the data between , IOH Chip , soft CPU and if , be in case of of , Path From Desktop , usual that the way QPI as a result , might still perform at not different from in the age of , Bloomfield , anyhow , be the channel takes to send the data between , CPU and IOH by pillar duty of IOH , that will the group , Pci-express Controller , for link up Graphic card , and lead the data from Graphic , a card sends to come in to CPU and memory , for do the data processing , and return go to again for show there , information other division from Chipset ICH or Southbridge , as a result , will still transmit way way that the name that , DMI , reach Chipset IOH , and change reach CPU change the way of , QPI next.
