Samsung announces new mobile SoC, the eight-core Exynos 5 Octa


During Samsung’s second CES keynote, the company announced an eight-core system-on-chip called the Exynos 5 Octa. The chip will be based on ARM big.LITTLE architecture, which incorporates four ARM Cortex-A15 chips and four low-power Cortex-A7′s. This allows for dynamic scaling based on the workload; less intensive tasks will use the A7′s, while gaming and HD video decoding will use the A15′s. The team also scaled the manufacturing from 32nm to 28nm, significantly improving thermal efficiency in the process.

The chip was designed for both smartphones and tablets, and will lean toward the high-end devices for both. These devices will be able to take advantage of the Exynos 5′s ability to multitask, as high and low priority tasks will be shunted to the appropriate sub-chip. Samsung boasts that it provides double the 3D performance of any other mobile processor; that should be good news to anyone who uses his device for gaming and video.

While there’s no word on when we can expect to see this chip in a Canadian shipping phone or tablet, it at least gives us something to look forward to. Now that Nvidia, Qualcomm and Samsung have all announced the next wave of mobile processors, 2013 is bound to be an interesting year for computing.

    This will be insane. My bet’s on the octa to rule performance, followed by qualcomm, then nvidia. Just cause that’s how it’s been for the past 2 generations.

    • Erik

      What about performance per watt?

    • Acco

      Hard to say. I’m going to go with Qualcomm on PPW. But I’d bet good money that we’ll see the Octa powering a future chromebook.

      RIP Android :)

      With this chep is definitely RIP RIM and APPLE!!

    Not sure I see the benefit of the 4 Cortex A7 cores. 1-2 would be enough, as they are only used when the phone is idle.

    • Richard

      Not only when the phone is idle. They are used under lighter load, like browsing the web, text messaging, basic tasks. When you start something that requires a little more oomph the the A15 cores will kick in givin you some extra power for those CPU intensive applications like games.

    • Tomatoes11

      I disagree. Four A7′s can do more tasks than 1 or 2. That way you rely less on the A15 cores. If you only had one A7, I would guess that one of the A15 cores would be active like 90% of the time.

      I guess they could have used two A9′s as the power saving cores but that is a little overkill.

    Before everyone starts OMG Octa core-ing this is more like Nvidias 4 + 1 where you have 4 going for heavy stuff and one going for light stuff, except this is 4 + 4

    • Brad F, Brad F(anboy), jack

      4 + 1 = 5
      4 + 4 = 8

      Hmm.. 8 > 5.

      OMG Octa core! Octa core! Octa core!

  • Kid.Canada

    But why? Even the quad core processors that are in phones now can’t be used to its full potential. Why is an 8 core processor necessary on a smartphone let alone a 4 core which is already too much for what it can do today. Why not focus on making bigger batteries, which is has a bigger priority, instead of making faster processors which is completely unnecessarily for a phone. Don’t get me wrong, I’m not against the progess of technology but you have to admit that this will be completely pointless and a major battery hog on a 4-5 inch smartphone.

    • justjoshin

      This will rule with ubuntu on it. This is what ubuntu were aiming at with there desktop convergence paradigm. The current generation of phones are slightly underpowered to be running fully fledged desktop apps.

    • CRTC

      This is not a “8″ core CPU. Its 2 quad cores. At any given time only 1 of the set of 4 cores will run. BIGlittle is 4 powerful a15 cores for lots of power, and 4 ultra low power a7 cores for light work. Majority of tasks will run on the 4 low power cores saving battery.

    • Gman

      marketing purpose, this is how average joe that claim to be a tech guru will tell you more cores = more power = best phone. Pretty common in Asia at least. Like the sales man will also tell customers this is the most powerful phone because the number of cores. If ppl program it smart enough, or the OS is optimized good enough, you don’t need low power CPU cores that and just runs everything with 1 CPU and spread the work load if for more intensive work. But having massive raw power is never a bad thing.

    • Richard

      There are only 4 active cores at any given time. 4 low-power cores to conserve battery, and 4 high-performance cores to give you the power needed to run demanding apps. It’s not about what apps can do with those today, but about what the next generation of apps will be able to do with those.

  • John

    2200MAH battery = dead in 4 hours.

    Seriously, these phones are going to need massive batteries to run the big a*s 5″ screens and crazy prosessors.

  • derpingtons

    Someone posted a mockery involving 4.X Ghz Octacore 8gb RAM phones a few weeks ago. nostradamus.

    This will sit nicely in the dash of my Hummer H1 With 40″ Rims

  • Hmza

    Okay. How do I say it?

  • TrickyD

    But can it run Far Cry?

    • Richard

      If you manage to find a build of Far Cry that’s been compiled to run on ARM processors, I’m sure it would.

  • Gsizzle

    Better come with a minimum 3500mAh Battery for smartphones.

  • Awkward Turtle

    Why?

  • Tomatoes11

    This sounds awesome but I am a little concerned about the concept. Usually these tricks have a consequence. For example, low polygon/textures with a lot of shading algorithms look almost as good as high polygon/ram intensive textures but you can still notice a difference.

    With the big little architecture, I feel that if the software isn’t coded properly, the chip set could perform more like a Quad core A7 rather than a Quad core A15. That is fine for something as light as IOS but Android needs the all out approach.

    meh, no support from cyanogenmod – no care
