How many pieces the number of processor cores that is ideal for mobile devices? One, two, four or eight? The last song that was chosen by Samsung for its newest mobile processor series, Exynos 5 Octa.
It announced the Samsung on stage exhibition CES, January 5, 2013 today, as if it were not to be outdone by two other processor manufacturers, Nvidia and Qualcomm, which also the highlights of each.
Although the core two times more compared with the previous generation processor, power save and promised Exynos 5 Octa disappears not to be of the battery the high-end smartphone or tablet that carries.
Because, for the eight core belonging to Exynos 5 Octa, only four high-performance. The fourth core is based on architecture Cortex-A15, just as the property of the Exynos 5 double used in Tablet PC Nexus 10 processor. The remaining four cores using the basic architecture of the Cortex-A7 optimized for energy efficiency, not performance.
The configuration is the result of the application of the concept of "large.LITTLE "of the ARM. The eight Central Exynos 5 Octa will distribute the workload dynamically according to the amount of tax on the system. For example, browsing or other soft things will be handled by core A7, while core A15 buy when running games or other "heavy" application.
Exynos 5 will be one of the first Octa processor is the concept of large.LITTLE of it, if not completely the first time.
This concept is a little different from the approach that Nvidia Tegra processors Tegra 3 and 4, where the chip manufacturers embed an extra core (core companion) that can be used only when the four main core is disabled.
Exynos 5 Octa happens with manufacturing proeses that promises more efficient power consumption 28nm in comparison with the 32nm process used to make Exynos 5 Dual.
A matter of a couple of graphics processor (GPU) used in SoC, the Samsung offers no specific information except the assertion that the performance twice as fast compared to previous generation processors will.
If the processor "earlier generations" in question 4, is Exynos 5 Exynos record Samsung Octa probably the Mali GPU-T604 as used by Exynos 5 double wearing.
