With last month's introduction of the Intel Xeon 5300 Clovertown series we have decided to look again at Intel's FB-DIMM memory performance. In this article we not only look at the pure memory bandwidth but we also see how it correlates to real world gains as we time the compilation of the Linux 2.6.19 kernel as well as running rounds of Enemy Territory and Quake 4.
