Samsung started to commit code related to Exynos 7 processor to mainline kernel in August, but at the time details were scarce, and many tech websites referred to a Exynos 5433 64-bit processor from Samsung. Exynos 5433 for a Cortex A53/A57 SoC did not make much sense as the company recently announced Exynos 5430 based on Cortex A15 and A7 cores, so finally Exynos 5433 has been renamed to Exynos 7 Octa.
Here’s what we know about Exynos 7 Octa from information on Exynos 7 Octa page and an older Anandtech article about Exynos 5433:
- CPU – 4x Cortex A57 cores @ 1.9 GHz , 4x Cortex A53 cores @ 1.3 GHz
- GPU – Mali-T760 @ 700 MHz
- Memory Controller – 2x 32-bit @ 825MHz (13.2GB/s b/w)
- Display – Up to WQHD (2560 x 1440) / WQXGA (2560 x 1600) resolutions
- Video – Advanced multimedia format codec (MFC) including support for H.265/HEVC @ 60 fps
- Camera – Up to 16 MP 30fps rear camera, Up to 5MP / 30 fps front-facing camera, with dual ISP allowing for simultaneous video recording.
- Process – 20 nm HKMG
A57 cores are said to provide 57% more performance than the A15 cores found in Exynos 5 Octa processors, whereas. Mali-T760 GPU should deliver up to 74% enhanced graphics performance over Mali-T628 used in Exynos 5 Octa.
Samsung Exynos 7 is used in the international version of the Galaxy Note 4 smartphone.

Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.
That chip has to be some sort of crippled version, not only rumor of running on 32-bit mode only, but even the memory is 2 * 32-bit is ridiculously low-end (@1650MTps while at it), and only supporting ancient legacy less that 4k/UHD resolutions.
Hopefully they finally do a decent 64-bit mode chip sooner, rather than later.
Phone vs tablet/STB = 32-bit vs 64-bit?
So basically this is the rumored Exynos 5433?
Something’s fishy here. I doubt that “A53 cores are said to provide 57% more performance than the A15”. It’s probably the high end A57 cores that are 57% faster than the A15 cores. A53 cores should have performance better than the A7 cores but they’re not high end cores.
Marius Cirsta: you’re right. “HMP technology along with ARM Cortex-A57 cores and Cortex-A53 cores provides a 57% CPU performance increase from the previous generation Exynos, Exynos 5 Octa.” (from Samsung’s Exynos 7 Octa page)

Yes, sorry typo. I meant to compare “new” big cores to “old” big cores.
Now, the only question is when guys from Hardkernel will give it a chance and put on some of their future boards. Seriously I’d like to have one ARMv8 here at least but as a hobbyist I refuse to pay $$$ asked for AMCC and current AMD prototype boards… 🙂
I’m excited as you are with this new baby.. 🙂 As soon as we can we’ll release our ARMv8 board 😛
