HTC already unveiled one of the first Android smartphones with a 64-bit Snapdragon chipset, the Desire 510, but it's saving the higher-end phone for IFA. The HTC Desire 820 teasers initially suggested it will be the first phone with a 64-bit octa-core processor.
One of the popular leaker accounts on Twitter has provided more info on the device – it will be a 5.5" phablet with a 720p screen, 13MP main camera, 8MP front-facing camera (!) and a 2,600mAh battery.
The chipset is listed as MSM8916, which is the same Snapdragon 410 chipset with quad-core processor that the Desire 510 is based on. It will allegedly come paired with 1.5GB of RAM and 8GB of storage.
The octa-core info came from a post on Chinese social network Weibo so there could be two versions of the Desire 820, HTC has put out more powerful, Asia-only versions before. Or it could be that the rumored info is wrong, we'll find out for sure next Thursday.
