Bensley Platform

Bensley Platform- A Comparitive Understanding

• Intel's shared bus architecture has several advantages; it is simple, easy to implement, cheap, and it is quite effective for two processor systems.
• However, when you have four CPUs on a single shared bus, there is not a lot of bandwidth to go around and there is an increase in cache coherency traffic to boot.
• All together, this makes Intel's shared bus a suboptimal solution for four processors or more.
• Fortunately, Intel has gone to great lengths to address these issues in Bensley.
• Figure 1 above  shows a comparison of the Lindenhurst platform to the Bensley platform.
• The main focus will be on the buses and the memory subsystem.
• The figure is self Illustrative and throws a comparative understanding with on going Lindenhurst platform architectures.
