Briefly about the new: Samsung introduced the first 8-core Exynos 5 Octa processor
Yesterday, at the CES 2013 international exhibition of consumer electronics held in Las Vegas, USA, from January 8 to 11, Samsung Electronics presented its latest SoC development: the world's first 8-core Exynos 5 Octa mobile processor, 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 in each, which significantly 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 processor, which ARM Chromebook and Nexus 10 are equipped with). The other four Cortex-A7 CPUs have the same set of features and capabilities as the A15 cores, but they are optimized for greater energy efficiency rather than performance. By the way, the energy efficiency indicators of the Exynos 5 Octa are 70 percent higher than those of the dual-core Exynos 5 Dual processor, while significantly exceeding the latter in speed.
The new SoC is designed to dynamically share the load between high-performance and energy-efficient processor cores: A7 cores are quite capable of cope with work in standard applications (checking mail, web surfing, 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 seamlessly with each other, which gives a theoretical opportunity to create a device that can set a new speed record, avoiding the merciless battery consumption. The new SoC is built on a 28nm process, which has been 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 that will be equipped with the new SoC, but company representatives said that it "is twice as high as any previous generation of processors." This is probably the same Mali-T604 GPU that can be found in the Exynos 5 Dual of the Nexus 10 tablet (device performance tests just showed about twice as much performance as Exynos 4).
