Redmi K20 Pro vs OnePlus 7 vs Asus 6Z vs Black Shark 2: A spec-battle of budget flagships

The Redmi K20.

As far as specifications go, the Redmi K20 Pro comes with a 6.35-inch display with an FHD+ resolution and 19.5:9 aspect ratio. The device has a fingerprint sensor of the in-display variety along with a pop-out front-facing camera which gives the phone a near bezel-less design.

Redmi's 'Flagship Killer 2.0' has certainly got the flagship-level internals as well. Powering the device is a Snapdragon 855 SoC which is paired with up to 8 GB of RAM and 256 GB of storage. The device runs on Android 9.0 Pie along with Xiaomi's MIUI 10 skin overlaying it.

In terms of optics, the Redmi K20 Pro has triple rear cameras which consist of a 48 MP primary sensor + 13 MP ultra-wide sensor + 8 MP telephoto lens with 2X optical zoom. The pop-out camera on the phone has a 20 MP sensor. In terms of video shooting capabilities, the device has a 960 fps slo-mo feature along with 4K @ 30 fps recording

All these high-end specs at surprisingly low-cost make you wonder whether there's a catch. Our review has found out that apart from nigh-time photography, the Redmi K20 Pro is a beast in every sense of the word. So here's a small spec-comparison of the device with the competition. For the purpose of this comparison, we have chosen the OnePlus 7 (Review), Asus 6Z (Review), and Black Shark 2 (Review).

Verdict

The triple-cameras on the K20 Pro offers a great value proposition amongst all the other phones, all of which have dual-cameras. Then there is also the fact that the K20 Pro offers 8 GB RAM + 256 GB storage at the lowest price and keeps the Snapdragon 855 chipset that all the others have. In terms of screen-to-body ratio, only the Asus 6Z seems to have a comparable display thanks to its flip-out camera. Like the PocoF1 before it, Redmi K20 Pro has again hit the bulls-eye for giving customers a worthy flagship smartphone at a very low-cost.
