The next Samsung Unpacked event is scheduled for August 23, and everyone expects to see the next-gen Galaxy Note phablet unveiled then. However, the details are not official yet, and it is always better to see some details on a benchmark database than to hear nothing but rumors from "insiders familiar with the matter."
As it usually happens, it looks like the Galaxy Note 8 will launch with both Qualcomm and Samsung processors. The unit spotted on GFXBench has a Samsung Exynos 8 chip inside, while the one that surfaced on AnTuTu features a Qualcomm Snapdragon 835. The list of common specs and features includes Android 7.1.1 Nougat, 6 GB RAM, 64 GB internal storage, a massive 6.4-inch display with 2,960 x 1,440 pixels, 8 MP/12 MP front/back cameras (most likely a dual camera setup on the back).
Strange enough, the AnTuTu database entry lists a screen resolution of 1,080 x 2,220 pixels. The model numbers are also different - SM-N950 on GFXBench and SM-N9500 on AnTuTu. For now, all these should be taken with a grain of salt, but the truth should be revealed next week.
