Samsung’s new octa-core processor is one of the company’s first chips based on ARMv8 architecture. The Samsung Exynos 7 Octa is a 64-bit chip that features 4 ARM Cortex-A57 CPU cores and 4 lower-power ARM Cortex-A53 cores.

The company says the new chip is up to 57 percent faster than its older Exynos 5 Octa processors.

The 8 CPU cores are arranged using ARM’s big.LTTLE HMP architecture which allows up to all 8 cores to be used at once.

The new chip uses a 20nm process and features ARM Mali T-760 graphics.

It supports screen resolutions up to 2560 x 1600 pixels, can handle 4K H.265/HEVC video playback, and has an image signal processor that can support devices with 16MP rear and 5MP front-facing cameras.

  1. Put that processor in a 13.3 inch Chromebook with 4gb RAM for $299 and I’ll buy two of them!

  2. It’ll be interesting to see how this compares in benchmarks to the K1 (both 32 and 64 bit versions) and the 32-bit Snapdragon 805!

    1. Was just going to ask if anyone knew how these stack up against the K1’s, I guess it’s early days & I’m sure we’ll see plenty of comparisons before too long.

      1. We also might have to wait for 64-bit versions of benchmark apps to show up if the code isn’t in there already. I think that’s why the 5S and 6 model iPhones do so well in single core tests in Geekbench against current 32-bit chips on Android.
        If I’m wrong and anyone wants to explain, correct me.

      1. If it’s 66% better than K1 that means it’s also quite a bit better than Intel’s BayTrail Atom chips, which would make it very interesting for use in Chromebooks! 🙂 (But I’m skeptical)

    2. I am not sure that the Exynos7 will beat the Denver K1 for everyday tasks, in a
      thermally-limited environment (like a phone or even a tablet). The Exynos7 will probably need to throttle back since 4 fully loaded A57s are fairly hungry.

      According to NV, Denver has much higher IPC compared to the base
      Cortex-A57 which Samsung uses in the Exynos7. True, the K1 it is only
      dual-core, so heavily multi-threaded apps will run slower on it than on a fully loaded, 8-core HMP Exynos7. In a phone/tablet environment, the workload is NOT heavily multithreaded, so the higher IPC of the Denver is actually a big advantage here (a good trade-off).

      The Exynos7 may be a better notebook processor than the dual K1 due to the number of cores. In a notebook environment, the full thermal envelope of the Exynos may be used without throttling so all of its raw power may be unleashed if the applications can utilize it (which I doubt, even in this environment). I hope NV produces a 4-core Denver variant for laptops soon.
