Rumors of an octa-core processor from Samsung have been floating in the smartphone world for a while. Also, CES 2013 was a bit boring in terms of Samsung's announcements. It looks like Samsung has answered both the problems with this one announcement. It managed to get us quite excited by announcing first ever octa-core SoC for mobile, Exynos 5.
Recently, Samsung announced its Exynos 5 SoC at CES 2013, an octa-core CPU based chipset. It is based on ARM's big.LITTLE technology and it consists of 4 ARM coretx A15 28nm cores running at 1.8 GHz(for heavy tasks) and 4 ARM cortex A7 28nm cores running at 1.2 GHz(for light day to day tasks). Because the SoC is based on 28nm architecture, it is supposed to be more energy efficient then previous Exynos SoCs and Samsung is claiming upto 25% increase in power efficiency. Although companies do claim more then reality to market their products but this one seems a legible one and if it comes out to be true the new SoC will become faster while become more energy efficient at the same time.
Although, Samsung din't announce the GPU of this SoC but considering the fact that Exynos 5 Dual contains Mali-T604 GPU, it seemed to be a safe bet that this one will feature the same but as it turns out Samsung is instead going to go with PowerVR 544MP3 GPU in the SoC. A notable fact is that Apple currently uses PowerVR 543MP3 in its latest A6 SoC which powers its iPhone 6 and 544MP3 only differs in the way from it is that it supports DirectX 10 rendering and 2X faster triangle setup. Also, Apple's A6X(which powers iPad 4th Generation) now uses even higher version of PowerVR series GPU namely PowerVR 554MP4. So, Exynos 5 octa-core SoC is expected to deliver graphical capabilities between those of Apple iPad 3 and iPad 4.
Although, the smartphone world is abuzz with the rumor that this will the heart of Samsung's upcoming Galaxy SIV smartphone but such rumors are surely to be taken with a bag of salt. But, we can say one thing for sure that it is going to be interesting what Samsung comes up with to harness the performance out of this beast.
