Phoronix: Intel Quad-Core Memory Performance

[ Thanks to Michael Larabel for this
link. ]

“One of the many benefits of Fully Buffered Dual Inline Memory
Modules is the ability to have up to six memory channels per memory
controller. Each memory channel can also support up to eight memory
modules. With that said the total number of possible modules is 48
(permitting the motherboard can handle that much), but how do the
numbers of memory channels in use affect the performance of Intel’s
new quad-core Clovertown processor? 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…”
