Redmi K50
With its four high-end processors from both Qualcomm and MediaTek, the Redmi K50 series may be the most comprehensive lineup from the brand to date. Since the previous Redmi K40 series only had three options, it’s clear that the lineup has expanded.

Redmi K50 Series:

According to @PandaIsVeryBald, Redmi K50 will be using a complete range of processors, such as the Snapdragon 870, Snapdragon 8 Gen1, Dimensity 7000, and Dimensity 9000′.
Snapdragon 870 was previously found on the Redmi K40 (Mi 11X / Poco F3), but the other three chips are all brand new and have not yet been used in a smartphone. Originally a flagship-level chip, the Snapdragon 870 was rebranded as a more affordable alternative to Qualcomm’s Snapdragon 888.
Compared to the Snapdragon 888, the Snapdragon 8 Gen1 will be a true flagship processor that will surpass it. Qualcomm’s chip was earlier rumored to be called Snapdragon 898, but has now been officially renamed.
From MediaTek, the Dimensity 9000 will be the brand’s top-of-the-line offering, and it will compete with the Snapdragon 8 Gen1. According to the latest reports, the Dimensity 7000 has already entered the engineering phase. With an AnTuTu score of 750,000, the Snapdragon X18 scored above the Snapdragon 870 but below the Snapdragon 888.
Redmi is likely to release four phones in this series. It include the Redmi K50, the Redmi K50 Game Edition, the Redmi K50 Pro, and the Redmi K50 Pro+. It should be expected, as always, that Xiaomi will go with different names for different regions. If Xiaomi sticks to its current naming convention, the Redmi K50 can be sold as the Mi 12X in India and as the Poco F4 in the rest of the world.
In terms of specs, the Redmi K50 Pro and Redmi K50 Pro+ will feature high-quality E5 AMOLED displays. Fast charging will be supported as well. The launch date is anticipated for either February or March.
