The world's thinnest phone to date breaks cover: meet the 4.85mm-thin, 64-bit Oppo R5

At this point, it seems that the race for thinner, leaner, and slender handsets won't stop anytime soon. During the past year or so, a number of different smartphones took the crown and reigned supreme in the slim department, most notably this year's Gionee Elife S5.5 and the 2013's Huawei Ascend P6. As usual, once you get at the top, almost everybody can take aim at you.

Such is the case with Oppo, the China-based manufacturer that is known for the devices such as the Oppo N1, the hot-out-of-the-oven Oppo N3, and the Oppo Find 7a, but henceforth it will be also known as the maker behind the world's slimmest phone - with dimensions of the 148.9 x 74.5 x 4.85mm, the Oppo R5 is the first device to wander into sub-5mm territory with its extremely slender, 3D-welded aluminum profile of 4.85mm. We'll let that one sink in. Yes, it's the thinnest smartphone at the moment (and don't get us wrong, this is an impressive milestone overall), yet it's note the sole highlight of this razor-thin trooper.

At 4.85mm, the Oppo R5 is the thinnest smartphone in the world

Inside the device, Oppo has fitted a phase-shifting, heat-absorbing material that adornd the device with optimal thermal efficiency, as Oppo puts it. Neat. The manufacturer has packed some pretty adequate hardware inside the device, too. See, the front is graced by a 5.2-inch AMOLED display with a resolution of 1080 x 1920 pixels. This puts the pixel density of the Oppo R5 on par with the one of the Sony Xperia Z3 - 423ppi. The piece of silicon that churns the nuts and bolts of the Oppo R5 is a 64-bit Snapdragon 615 SoC comprising eight Cortex-A53 cores and humming at up to 1.5GHz – not the most potent chipset we've seen, but it should do the job just fine, shouldn't it?
