Samsung Exynos 4212 is the successor to 4210 that power the SGS2.It is built using a 32-nanometer process compare to 45-nanometer process on 4210 of SGS2, 4212 packs a new graphics core, which should deliver up to 50% faster rendering of 3D graphics.

even if you overclock your SGS2 to 1.6 ghz or even 2.0 i dont think you can beat the 4212
