Either ways, the current silicon king in the mobile space, Qualcomm, didn't take long to announce it's own plans to make the jump towards 64-bit processors, with processors like the Snapdragon 410, 610, 615, 808, and 815, all of which will be based on ARM's new 64-bit architecture. And while chip development usually takes a long time (in smartphone years, that is), we're already getting the first real hints that the first slew of devices powered by Qualcomm's 64-bit chips are around the corner. More specifically, a recent run through the GFXBench benchmarking suite left traces of a Samsung device that was powered by a 64-bit Snapdragon 410 chip and an Adreno 306 GPU.
4.2 KitKat.The rest of the specs powering this still mysterious Samsung device (SM-G510F) include a 4.8-inch, 540 x 960 (qHD) resolution display, 1GB of RAM, and 8GB of internal storage. As for imaging, the SM-G510F makes do with an 8-megapixel rear snapper capable of 1080p video capture, and a 5MP front-facing selfie cam. Lastly, the device in question ran Android 4.
As for the type of performance you can expect from a device with similar specs, this GFXBench pass already provides some clue. That said, do keep in mind that this is likely a model in early development, so further optimizations could (and likely will) take place. With that in mind, we've got to say that we weren't very impressed -- when compared with the Moto G (which has a more demanding, 720p screen), the SM-G510F managed to snatch a victory in several tests, but not by a mile. But we'll give this the benefit of the doubt and wait until these first 64-bit Android devices become a market reality. Until then, sit tight.
