Earlier this week, Samsung announced that it was bringing Heterogeneous Multi-Processing (HMP) to Exynos 5 Octa chips. Samsung didn't clarify if HMP would require new hardware, but that was the implication. Now Meizu has unexpectedly announced the Exynos 5 Octa chip in its recently unveiled MX3 will be getting HMP through a software update.

All Exynos 5 Octa processors until now have used cluster migration to manage the ARM big.LITTLE cores. That means either the four high-power A15s are active, or the four low-power A7s are cranking away. There was no way to mix the active cores from the two CPU islands. To make matters worse, Samsung's implementation of cluster migration was broken by a cache bug. Switching between CPU islands caused the cache to be flushed from memory. Moving to HMP should fix that problem by allowing the system to assign tasks dynamically to both A7 and A15 cores. All eight cores could even be running at the same time.

Meizu is one of the few OEMs buying Exynos chips from Samsung and has a close relationship with the South Korean company. Presumably it has the inside scoop from Samsung on what its chips are capable of. This opens the door for HMP upgrades on other Exynos 5 Octa devices.

    Sorry for being off-topic, but why is the top image of the left device in German? o_O

    • Miah

      erm, a German content maybe?

      • Thomas’

        In an all-chinese content store?

      Ve Gerrmans are coming for your soul :P (Yes, I am one)

        I am scared :(

    Well, this changes things for the better. Although, to be honest, I've grown accustomed to Snapdragon S-series chips because of their power and efficiency. I put down my Note 2 for a week and have been using an AT&T S4 and noticed that the experience is smoother (also in heavy games like Most Wanted) while maintaining a day-long battery.

      I can't get "day-long" battery out of my AT&T S4, rooted / stock. Probably because I have Lookout in the background. Mine lasts maybe 8 hours. My friends with Note II's get "day-long" batteries.

      The good thing about this though is that even though cranking up features, brightness and apps in the background drain my battery.. I got a spare in my pocket thanks to the plastic that everyone for some reason despises.

    • spydie

      Lots of people reporting the lagginess in the S4... none in the Note 2, thank God

      • Pedro4Prez

        None in mine, rooted and running Hyperdrive

      • ProductFRED

        Opposite for me. AT&T S4 running Wicked ROM 5 (T-Mobile based) and kTweaker kernel.

      • JJCommonSense

        they probably need to update their firmware

  • blah

    Are those iphones in the post image?

    • Rovex

      No those phones in the post are the right shape.

    • PamelaLibrarian

      No they're Meizu phones.

  • Jadephyre

    HMP ?

    • Justin W

      Heterogenous Mulit-Processing. Interesting name though.

      • John O’Connor

        het-erogenous?

        • Justin W

          Yes. The definition according to Google is Originating outside the organism, so basically it's going to use two "processors" (or in this case, the A15 and the A7) at the same time.

    • http://turbofool.com Jarrett Lennon Kaufman

      Yes. The thing that's described in the very first line of the article you're commenting on.

      • Nick Klenchik

        People don't read, they like the pretty pictures and continue to the next atricle

    • Angel

      HMP DAY!!!

      • Jonathan Isenberg

        WOOT WOOT!!!

  • Anfronie

    This is making the new Note 10.1 look all the more better...humm... will the new note get this eventually?

    • Justin W

      I'm willing to bet it already has it included on the ones that have the Exynos 5 Octa (which means those that utilize only 3G).

      • Anfronie

        And the wifi only ones right?

        • Justin W

          Derp, yes. I was thinking of Note III, but thanks for bringing that up - it'll probably be included on Note III devices that utilize only 3G and Note 10.1 2013 edition, plus available as a software rollout to other devices.

  • เกรียนเทพ ดี อันลิมิเตด

    Now, Samsung can't avoid their older devices as Meizu says it out loud like this.

  • Ale

    What kind of icon are?

  • Paul

    Interesting. I guess that's good, but the U.S variant of the Galaxy Note 3 will have an Exynos 800 so I guess it's not relevant to me. I don't know of any U.S phones actually that have the Octa Core.

    • Happy Man

      Exynos 800? :D

    • Cheeseball

      Exynos 800! :D

  • xmylo

    how can i got those Icons :D ?
