Galaxy Note 4 and was previously known as the Exynos 5 Octa (5433). Apparently Samsung thought its first 64-bit chip deserved better treatment than that.
With the Exynos 7 Octa, the company is going to have a much better
time with customers differentiating the more powerful Galaxy Note 4 from
the Galaxy Alpha,
which also packs an Exynos 5 Octa (5430). However, it's a much less
powerful one with a quad-core 1.8 GHz Cortex-A15 and quad-core 1.3 GHz
The Exynos 7 Octa features a octa-core cpu consisting of four
Cortex-A57 and for Cortex-A53 cores made using Samsung's 20nm
manufacturing process. This results in a 57% boost performance over the
previous generation Exynos 5 Octa chipset and thanks to the new
manufacturing process, draws less power, too.
