Samsung Officially Announces Exynos 7 Octa big.LITTLE ARM Cortex A53/A57 Processor

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.

Exynos_7_OctaHere’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.

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)

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 😛
