Probably you heard that the ASUS Zenfone 3 Deluxe model, which is the top-end variant in the lineup will have another version reportedly sold in some Asian countries. The major difference in the new model would be that it will be powered by the Snapdragon 823 chipset. However, now, we have just spotted a promotional material of the ASUS ZenFone 3 Deluxe which reveals that the phone is powered by Snapdragon 821 and not Snapdragon 823. So, the SD821 powered variant of the device could be announced later.
The name doesn’t matter much. Whether it’s called the Snapdragon 821 or Snapdragon 823, the chip would just be a gentle upgrade to the existing Snapdragon 820 SoC. This makes sense, because 820 is already a powerful chip, and even if it was going to be upgraded within a year, it should be only a gentle one.
