One of the highlights of this year CES was the announcement of an Octa-Core mobile SoC from Samsung – the Exynos 5 Octa. This absolute beast of an SoC makes use of ARM’s big.LITTLE implementation and packs 4 Cortex-A15 based cores, and 4 lower-power Cortex-A7 based cores, manufactured on the 28nm HKMG process.
The use of ARM’s big.LITTLE technology will allow this SoC to provide the best of both worlds – performance and battery life. On the GPU side, it was assumed that Samsung went with ARM’s Mali GPU, which was found inside the Galaxy S II and the Galaxy S III.
However, it looks like Samsung may have had a change of heart and has instead used PowerVR’s Imagination GPU on its latest SoC. AnandTech has confirmed from multiple sources that the Exynos 5 Octa SoC packs in three cores of PowerVR SGX543 GPU, with each core clocked at 533MHz.
This is the same GPU that Apple uses in its A5 and A5X SoC, with the latter being found inside the third generation iPad. Considering the PowerVR SGX543 inside the Exynos 5 Octa SoC is clocked so high, it should be able to beat the 3rd generation iPad in benchmarks. However, it won’t be able to surpass the performance of the A6/X SoC found inside the iPhone 5 and the fourth-generation iPad.
There is a very strong possibility that Samsung will end up using the Exynos 5 Octa SoC on its upcoming Galaxy S IV smartphone.
