I'm completely confused. I've upgraded sisoft sandra from 2010.SP1d to 2012.1824, and it's reporting completely different benchmark figures.

From identical settings, aggregate memory performance in Memory Bandwidth test has gone from 29.2 GB/sec to 27.8 GB/sec. Memory latency has gone from 42ns to 17.7ns (!?).

Anyone know what's going on?
