nanoseconds (lower is better)

The memory performance is greatly improved in the B3 Phenoms – with not only lower latencies but faster read, write and copy speeds. The write speeds are still "limited" but Everest does only load one out of four cores. The yellow turbo mode is virtually identical to the red turbo mode – there's very little memory performance and there is no latency difference.
