These results are reflective of the strengths & weaknesses of the Samsung system versus the Snapdrapgon, with the Snapdragon having a better FPU & thus winning by far on Linpack. The previous-generation Snapdragon SoC in the Streak (8250) also has a weaker GPU so the Samsung beats it in graphics regardless of OS.

But Froyo on a Snapdragon is very old news indeed. The Gingerbread source will be out any minute now.
