Alongside the headline-dominating Xiaomi 12 and Xiaomi 12 Pro, Xiaomi also launched the Xiaomi 12X at its event in China today. The Xiaomi 12X appears to be a more affordable variant of the Xiaomi 12, with one notable difference being the use of a Snapdragon 870 over Qualcomm's new Snapdragon 8 Gen 1.

this is the phone i would buy out of the three, because it is small + it has the sd870 which is more efficient being made on tsmc. BUT, xiaomi has priced it very high, very close to the normal 12 so, for 80$ more I would just get the normal 12 or even the 12 pro instead. base price for 12x is 500 bucks and base price for 12 is 580$. I would have expected the 12x to be more like 400-450 bucks.
