Sony Mobile Communications Inc. on Wednesday unveiled its next-generation Xperia Z5 and Xperia Z5 Compact, alongside “the world’s first 4K smartphone,” the Xperia Z5 Premium.

Along with the 4K display, the Xperia Z5 features Sony’s new 1/2.3 Exmor RS for mobile 23-megapixel sensor and F2.0 G Lens. Sony said this is its first “completely re-imagined” smartphone camera module since Xperia Z1.

Being a flagship offering, the Xperia Z5 Premium has to compete with other flagship offerings available right now. Below we compare the Xperia Z5 Premium to four rivals.

Note: On September 9, Apple is expected to unveil its next-gen iPhones, the iPhone 6s and iPhone 6s Plus. The iPhone 6s Plus is said to feature Apple’s A9 chip, 2GB of RAM, an upgraded LTE chip, 12-megapixel rear camera, upgraded FaceTime camera, Force Touch technology and run iOS 9. Naturally, the iPhone 6s Plus will become the new yardstick for phablet-sized flagship smartphones and we’ll have an updated comparison post-launch.
