F4 or X4 GT: Poco mid-range smartphones in comparison
Poco has two smartphones in the mid-range in the F4 and X4 GT models. The differentiation of the nomenclature is complicated by the fact that there is also an F4 GT, which is more expensive and offers even more performance.
What the F4 and X4 GT have in common is the camera setup - at least on the back. Both offer a 64 MPix main camera that performs quite well in our review. The results of the wide-angle and macro lenses are less impressive. The photos are usable, but the quality is clearly below that of the main lens. On the other hand, there is a difference on the front. While the camera in the F4 has a resolution of 20 MPix and shoots nice selfies - even though lens flares occur in backlight - the manufacturer uses a 16 MPix camera in the X4 GT.
The main differences between the devices are the display and the installed SoC. The F4's 6.67-inch display is slightly larger than the X4 GT's 6.6-inch panel, but it is mainly the installed technology that makes the difference. The F4 is equipped with an OLED screen that shines with perfect black levels thanks to its design. The screen also impresses with a decent brightness level of 1274 cd/m² under testing, while the refresh rate reaches a maximum of 120 Hz. The X4 GT even delivers 144 Hz, but technically uses an LC display. Poco specifies a maximum brightness of 500 nits here.
The F4 is powered by a Snapdragon 870 with an Adreno 650 graphics unit. Although the SoC is not brand-new, it nonetheless ensures strong performance in the smartphone. Even current games can be played in high settings. The X4 GT, on the other hand, relies on the power of the MediaTek Dimensity 8100 in conjunction with a Mali-G610 MC6 GPU. Both come with UFS 3.1 storage, a capacity of 128 or 256 GB, depending on the version. The F4 has 6 GB of RAM in the small version, while the X4 GT has 8 GB in both versions.
