nanoseconds (lower is better)

Sisoft Sandra loads all the cores when testing memory bandwidth and again the Phenom B3s stand out against the older B2s with improved memory performance and lower latencies. The extra 200MHz northbridge frequency on the 9850 has a significant effect although it's a shame AMD couldn't get this running 1:1 like on the Athlon 64 X2s.
