The Meizu MX5 is not official yet, but recent leaks suggest that when it does launch it will not come alone – the Meizu MX5 Pro will join in with a 6" QHD screen and a chipset sourced from Samsung. Two photos show the back of the bigger device, which looks different from its non-Pro sibling – a flat glass pane, instead of beveled plastic.
The 6" screen is rumored to have a QHD resolution but that may mean the unusual 1,5360 x 2,560px resolution from the MX4 Pro (it's not that unusual, it's just the 15:9 version of QHD).
Anyway, the new Pro model will allegedly use Galaxy S6's chipset, the Exynos 7420, trading up from the octa-core MediaTek its smaller bro will use (perhaps a MediaTek Helio X10). The MX5 Pro is expected to pack more RAM too, 4GB, up from 3GB for the regular MX5.
The camera seems to be the same 20.7MP/2160p shooter as earlier models have used. The launch date for the Meizu MX5 Pro should be some time next month.
