This, coupled with the rumors for a 5.5" screen diagonal, means that we might not see any wonders with the screen-to-body ratio of Samsung's upcoming flagship, but let's not get ahead of ourselves just yet. The chipset listed is an octa-core endeavor with ARMv8 instructions set, and a Mali-T768 graphics unit.
7 Octa family, that features 64-bit architecture, clock speeds up to 1.8 GHz, and is done with the trendy 20nm process. It will eventually be paired with a tri-band LTE Category 10 modem, too.
So far so good, but here we come to the strange part. We've heard that Samsung is musing between a 16 MP and an even more generous 20 MP camera sensor for the S6, but until now had no tangible proof of this soul-searching process. Well, the first AnTuTu leak had the SM-G925F model listed with a 20 MP sensor, while this one is outfitting it with a 16 MP shooter on the back.
Also, let's not forget that there might be two versions of the S6 - a regular one for the mass Samsung fan, and a speculated experimental model with a dual-edged flexible AMOLED display, which will undoubtedly go for much more than the base version, similar to the Note 4 and Note Edge duo.
If history is any indication, we should see the S6 announced around the MWC expo in February-March, with an April release date to follow.
