In terms of performance, there’s very little to separate the two phones. The Realme X2’s Snapdragon 730G SoC is optimised to offer better gaming performance than the standard Snapdragon 730 chipset on the Redmi K20. However, both chipsets are capable of delivering excellent gaming performance.

Design and Display

The most noticeable changes on the phone come in the form of design and display. The Redmi K20 offers maximum screen real estate by incorporating a pop-up selfie camera, while the Realme X2’s waterdrop notch feels a bit outdated. Both phones feature an edgy paint job with Gorilla Glass 5 on the front and back. Additionally, only the Redmi K20 supports HDR content. In terms of colour accuracy and brightness, the Redmi K20 does have the edge over the Realme X2.

The Realme X2 gets a quad-camera setup with a 64-megapixel sensor at the helm, while the Redmi K20 offers a triple-camera setup with a 48-megapixel primary Sony sensor. On the front, Realme opts for a 32-megapixel, f/2.0 lens, while Redmi utilises a 20-megapixel, f/2.2 motorised pop-up selfie camera. In terms of the front camera, the X2 does have an edge. Realme also offers a macro lens for getting up close to subjects. The Redmi K20, on the other hand, features a telephoto sensor, which provides better details in zoom and portrait shots.

Battery and Software

Both phones pack a similar battery size, but Realme offers 30W fast-charging support while Redmi is limited to 18W fast-charging. Additionally, Realme also does a better job with the software. ColorOS may not be the cleanest Android skin, but it is miles ahead of MIUI.


While the Redmi K20 gets a better design and display than the Realme X2, the latter does have a slight edge in performance. Additionally, the fast-charging support and cleaner software, which is set to improve with the next edition of ColorOS, make the Realme X2 a better overall smartphone than the Redmi K20. When it comes to overall camera performance, we’d also suggest opting for the X2 over the K20.
