The Exynos 5 Octa chipset currently runs on the international variants of the Samsung Galaxy S4 and the Galaxy Note 3. But shortly after the announcement of the Galaxy Note 3, it was claimed that OEMs can enable true octa core support for the Exynos 5 Octa chips, allowing all eight cores to run simultaneously instead of the standard 4+4 architecture currently seen on these octa core chipsets. But Samsung has now clarified that it won’t be able to bring this update to the current crop of hardware citing performance and stability issues. This means that the Galaxy S4 and the Galaxy Note 3 will settle with the standard configuration of Exynos 5 Octa.
According to Samsung, enabling true octa core support is possible through a software patch, but the hardware is not engineered to sustain the amount of heat which will generate from so much power. So the only workaround for this would be to enable this feature and rework the internal architecture from the ground up before enabling true octa core support. So it is indeed a hardware issue and hopefully Samsung will look to rectify this when the next crop of flagships arrive. Chinese manufacturer Meizu expressed optimism about bringing true eight core support to its Exynos 5 Octa running smartphones like the MX3. But after hearing what Samsung had to say, we’re not sure if Meizu will be able to live up to its promise.
