Samsung's Exynos 5433 is an A57/A53 ARM SoC
 

There has been a lot of confusion going on over the last few weeks on what exactly Samsung's Exynos 5433 is. Me and Joshua were pretty much convinced that it was a standard big.LITTLE A15/A7 chip configuration due to naming consistencies and evidence in firmware. Even though the Note 4 was already announced with region-specific models employing this chip, Samsung S.LSI has yet to divulge any kind of official information on the matter or even publicly announce the chip.
