A reader of this site asked me if I had a detailed breakdown of the components of memory latency for a modern microprocessor-based system. Since the only real data I have is confidential/proprietary and obsolete, I decided to try to build up a latency equation from memory…. Preliminary Comments: It… read more

Opteron Memory Latency vs CPU and DRAM Frequency
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
