The much-rumored Samsung Galaxy S5 has leaked in some interesting images, showing a high-end smartphone with a stylish metallic build instead of the regular plastic.

Samsung recently released the Galaxy S5 as its flagship smartphone for 2014, but the rumor mill is busy churning about another variant, higher-end and built with more premium materials.

This top-notch variant of the flagship is rumored to launch as the Samsung Galaxy S5 Prime, and the folks over at Phone Arena have received three intriguing images allegedly showing the handset.

If you haven't followed the rumors so far, the Samsung Galaxy S5 Prime is expected to boast a 5.2-inch QHD display with an impressive resolution of 2560 x 1440 pixels. Under the hood, the smartphone powerhouse will reportedly pack a quad-core Qualcomm Snapdragon 805 processor, as opposed to the Snapdragon 801 chipset found on the existing Galaxy S5 model.

The Prime version will also spice things up in the RAM department, sporting 3GB of RAM instead of the 2GB the standard Galaxy S5 packs. Moreover, Samsung is also expected to replace the Adreno 330 graphics in the regular version with an Adreno 420 GPU, which should come as exciting news to mobile gaming enthusiasts. On the software side, the new Galaxy S5 Prime is expected to rock Android 4.4.3 KitKat out of the box.

Phone Arena further points out that Samsung aims to beat LG to the punch, as the latter is about to launch its next-generation flagship, the LG G3, with a QHD display and top-end specifications.

Aside for the aforementioned specs, the Samsung Galaxy S5 is also expected to come with an aluminum body, finally breaking Samsung's love of plastic. The leaked images also show that the speaker is relocated on the bottom of the phone instead of the rear, and the new design also seems to be slightly curved at the back. The Samsung Galaxy S5 Prime will apparently sport the same perforated look as the original flagship, though this time it will be all metal-clad.

These newly-leaked images look pretty legitimate, but there's no way to determine for sure whether they're the real deal or not. At the same time, all of these specifications are based solely on rumors and speculation, with nothing officially confirmed. As always in such cases, it is highly recommended to take everything with a grain of salt for now.

Phone Arena's source further said the Galaxy S5 Prime is currently undergoing testing. If this turns out to be true, the new smartphone should become official soon enough. We'll keep you up to date as soon as we hear more, so stay tuned.
