In a recent post (link) I showed that local memory latency is weakly dependent on processor and DRAM frequency in a single-socket Phenom II system. Here are some preliminary results on memory bandwidth as a function of CPU frequency and DRAM frequency in the same system. This table does not… read more

In an earlier post (link), I made the off-hand comment that local memory latency was only weakly dependent on CPU and DRAM frequency in Opteron systems. Being of the scientific mindset, I went back and gathered a clean set of data to show the extent to which this assertion is… read more
Memory latency for local accesses on a wide range of computers using AMD Opteron processors.
