Sony has already launched the Xperia Z1 f exclusively on the NTT DoCoMo network in Japan. Sony Xperia Z1 f powered by Snapdragon 800 chipset with quad-core Krait 400 CPU. The benchmark test in question is AnTuTu and the result it shows are quite intriguing. Since the Xperia Z1 and Xperia Z1 Mini share the same chipset, you’d expect them to perform the same. However, that’s not the case.
The Xperia Z1 Mini scores 34,376 points in AnTuTu, while the Xperia Z1 managed just 30,850 points in our test. The reason for the difference in the performance is sure to be the displays of both devices. The Xperia Z1 features a 5″ 1080p display, which is much more demanding than the 4.3″ 720p display of the Z1 Mini.[via] RBMen
