High-resolution display, Exynos 5430 processor touted in premium Galaxy S5
A premium version of the Samsung Galaxy S5 could be on the way, according to a rumor. The leak suggests that the "Project KQ" smartphone could have a QHD display, rather than the 1080p screen used by the Galaxy S5 at launch, and that these previously-rumored features were being mulled over by management before being removed from the device.
SamMobile claims the Galaxy S5 went through ten prototypes, with the initial prototypes using the higher-resolution display, though this was evidently removed at the third iteration. It is thought that production issues for the QHD screen lowered the levels of production Samsung wanted for the device, promoting the step down. The display is apparently still used in the late-phase development of Project KQ, with the Galaxy S5 known in production as Project K, and is being combined with an Exynos 5430 processor and Intel-powered LTE.

The Exynos 5430 uses four Cortex-A15 cores clocked at 2.1GHz and four Cortex-A7 cores at 1.5GHz, combined with a 600MHz ARM Mali GPU. The processor also uses a HEVC controller that can support up to 8K video playback, far in excess of what is required for a QHD smartphone, and a dedicated Cortex-A5 for audio processing.
It is believed that the Exynos version of Project KQ is for the South Korean market and not for global release. A second version, which is thought to be a derivative of the KQ, has apparently been caught using a Snapdragon 805 processor instead, and could be the international model.
So far, Samsung has yet to hint at releasing a premium version of the Galaxy S5 officially. The manufacturer did recently invite media to an event on April 29th for a device with a connection to the letter K, though it is believed to be the launch of a camera-focused Galaxy S5, a similar device to the Galaxy S4 Zoom.
