Yesterday, as part of the CES 2013 international consumer electronics exhibition held in Las Vegas, USA, held from January 8 to 11, Samsung Electronics unveiled its latest SoC-development: the world's first 8-core mobile processor Exynos 5 Octa, which was created for the subsequent applications in advanced tablets and smartphones. This chip is based on the big.LITTLE architecture, i.e. The processor has two different groups of ARM cores — four cores each, which greatly improves performance and energy efficiency, which are critical factors for future hi-end gadgets.

One of the clusters carries four high-performance Cortex-A15 cores (the same cores can be found in the Exynos 5 Dual dual-core processor, which is equipped with an ARM Chromebook and Nexus 10). The remaining four Cortex-A7 CPUs have the same set of features and capabilities as the A15 cores, but they are optimized for greater energy efficiency, not performance. By the way, the Exynos 5 Octa's energy efficiency figures are 70 percent higher than those of the Exynos 5 Dual dual-core processor, while significantly outperforming the latter in speed.

The new SoC is designed for dynamic load sharing between high performance and energy efficiency of processor cores: the A7 cores are fully capable of handling the work in standard applications (checking mail, surfing the web, etc.) with low power consumption, while ARM Cortex A15 will provide excellent performance in demanding applications and games. The A15 and A7 cores can work together seamlessly, which makes it theoretically possible to create a device that can set a new speed record while avoiding mercilessly devouring a battery. The new SoC is built on a 28nm process technology, which was claimed to be more energy efficient compared to the 32nm process used in the production of Exynos 5 Dual.

During the presentation, Samsung did not disclose the name of the GPU, which will be equipped with a new SoC, but company representatives noted that it "is twice the performance of any previous generation of processors." Probably, we are talking about the same Mali-T604 GPU, which can be found in the Exynos 5 Dual of the Nexus 10 tablet (the performance tests of the device just showed about twice the performance than the Exynos 4).
