Maybe the Sandy Bridge platform is running on not dual channel DDR3?

Previous benchmarks have shown that Sandy Bridge has very high memory bandwidth (higher than Nehalem) yet in the benchmarks shown show a different story.
Which benchmarks have shown that? I can hardly believe that SB could nearly(x1.93) double the memory performance. What I believe is RAM running at lower speed. E.g. 1600 vs 1866 MHz. There, the difference would be approx 14 %.

What kind of efficiencies are the current Intel offerings getting at memory bandwidth?
