The Galaxy S II GL Benchmarks have begun to surface:

This new average is very, very impressive. Compared to Hardkernel Odroid-A development platform (also Exynos 4210), the results are similar, which implies that the resolution is weakly correlated with frame-rates up to at least 1366x768. The bottom line? The Exynos 4210 w/ Mali 400 is looking like a very fast SoC.

The Galaxy S 2 should excel at gaming.
