Any difference between the Redmi Note 4 & Redmi 4 phone?

If it's the same, I rather take the Redmi 4 since it's smaller.

Edit: Just checked that there are also Redmi Note 4 Pro but I can't find it in the net. Is RN4 Pro = RN 4X?

Nobody's answering, so I answer it myself.
After few hours of research, this is what I found.

1) RN4 =/= Redmi 4. Both using difference processor/GPU
2) RN4 = RN 4X (malaysia version). The difference is probably the camera sensor.
3) RN4 Pro => the "Pro" is simply to denote it is using Snapdragon processor. Sometimes RN 4X Pro appears, where the Pro is to denote it is using SD processor as well.
