What is quick path interconnect. Its advantages ?
A. In the earlier designs the processor used to connect to the north bridge, which in turn used to connect to the memory controller and the south bridge. In the core i7 the memory is connected directly to the processor. A new interconnect technology QPI ( Quick path interconnect) has been introduced. One advantage is potentially higher data through put rate. The biggest advantage of QPI is its ability to connect to another processor. Processors can communicate to each other directly using QPI. This opens up several possibilty. For example, a motherboard can have two core i7 processors boosting performance required by gaming desktops. AMD was leader in this technology in its Opteron processors using it Hypertransport Bus. Intel is following AMD’s footsteps by using QPI tech Q. How does the cache memory of core i7 differs from the core 2 processors. A. The L1 cache of the core i7 is same as that of the core 2 processors – 64 KB of the L1 cache divided into 32 KB of data and 32 KB of inst
