I wonder what the version sold on Amazon. Indeed, there is a difference between the two, in particular at the processor. To enter in the art, the GT-i9100 Samsung Exynos SoC integrates a 4210 GT-i9100G a Texas Instruments OMAP4430. Certainly they house both a CPU ARM Cortex-A9 dual-heart 1.2 GHz, but the first houses the ARM Mali GPU young MP-400 while the second houses the older PowerVR SGX540. Performance tests have also shown that the first CPU was better than the second, which limits most of the time at 1.0 GHz, even under load.
