You can order the Xiaomi Mi3 with the Tegra 4 but there were no clues earlier about the Snapdragon version of the device. So if you guys feel that the Tegra 4 is not that promising there is Snapdragon 800 version for you out there and that too with the same price tag of 1,999 Yuan.
According to the company Mi3 Snapdragon would be listed in china sometime in December, also with the Wi-Fi 801.11ac protocol which was found missing in the Tegra 4 version.
Obviously the Snapdragon version would be faster. It would have better clock speeds. Snapdragon Version(MSM8974AB) would have 2.3 GHz of core speed, 550 MHz of GPU speed and 993 MHz LPDDR3 speed, whereas the Tegra 4 version (MSM8974) has 2.2 GHz core speed, 450 MHz GPU speed, and 800 MHz LPDDR3 speed. So a better performance is guaranteed.
