Meizu says Exynos 5 Octa HMP is a software upgrade, will get to current products
Samsung has been touting the eight cores in its Exynos 5 Octa CPUs for months now.
The problem is that Exynos 54×0 is not a truly octa-core chip. It’s built on ARM’s big.LITTLE architecture, and has 4 ARM15 cores for processing intensive power hungry tasks, and four slower more energy efficient ARM7 cores for mundane stuff. And, until now, your apps could use only ARM7, or ARM 15 cores, but not both of them at the same time. Giving Samsung competitors, like Mediatek and Qualcomm, an opening to dismiss Exynos 5 as not truly an octa-core chip.
Things are about to change. Yesterday Samsung announced Heterogeneous Multi-Processing Capability (HMP) for Exynos Octa, that will allow developers to to use all 8 CPU cores at once for their apps.
But Samsung wasn’t clear whether HMP needs some hardware tweaks, or is it just a software patch, that can be pushed to already shipping Samsung phones with Exynos Octa. Can Samsung Galaxy S4 you just bought, or Galaxy Note 3 you are about to buy, be upgraded with HMP?
Now we have the answer. And it’s a “Yes”
The confirmation that current Exynos Octa chips can be upgraded with HMP comes from Chinese Meizu. Their newest smartphone– MX3, also runs on Samsung’s Exynos-Octa chip. In today’s blog post talking about power efficiency of MX3, Meizu said their flagship will get HMP upgrade later this year.
Which suggests it can be done via software patch, so your Galaxy S4 and Note 3 should get faster and more power efficient in a few months.
