Basically both the I9100 and I9100G have the identical features as claimed by Samsung but the only thing that differentiate both is the processor and GPU that the unit run. I9100 run on 1.2GHz ARM CortexA9 Exynos 4210 and ARM Mali-400 GPU while I9100G uses Texas Instruments OMAP4430 CPU and PowerVR SGX540 GPU.
While according to the review from Lowyat member, the processor for I9100G seems to be capped at lower clock speed of 1008Mhz and it seldom goes up till the 1.2GHz as claim by Samsung even while performing Stress Test or benchmarks. But one thing for sure, the I9100G seem to have a better control of Galaxy S2′s poor battery life and overheating issue faced by most of I9100 users. And as claim by the review, user of I9100G may encounter some problem to download some apps / games in the Android Market/Samsung Apps on I9100G as it failed to be optimized for the TI processor.
在我看来,lag的主因是因为cpu比较低造成的,当初出G版的时候已经有消息了,G版的比较省电,因为很少会去到1200mhz,都是control在1000mhz左右。当然这个是见仁见智的问题,因为我的s2基于省电的理由都被我控制在800mhz(我个人做事比较专心很少multitask,一点点的lag在我接受的范围就ok)
