The handset will be powered by the Snapdragon 810 chipset, which includes an octa-core 1.9GHz CPU and the Adreno 430 GPU. 3GB of RAM is inside, along with 32GB of native storage. A 23MP camera is on back, which will record 4K video. The front-facing camera weighs in at 8MP.
The Sony Xperia Z5 Compact offers a 4.6-inch display featuring a 720 x 1280 resolution. Also powered by the Snapdragon 810 SoC, the Xperia Z5 Compact is equipped with the same octa-core 1.9GHz CPU and Adreno 430 GPU found in the full-size unit. 2 GB of RAM is inside, along with 32GB of internal storage. The 23MP/8MP camera combo features the same camera modules employed by the Xperia Z5.
There is also speculation that Sony will announce the Xperia Z5 Premium, with a 5.5-inch display carrying a 4K resolution. That would provide a pixel density above 800ppi, and would be the highest resolution found on a smartphone screen to date.
The company is unveiling its new Xperia Z5 lineup tomorrow, so make sure to check in here early and often.
Thanks for the tip!
