Nvidia Tegra systems within single chip which is material
form like 4plus1. Unlike the latter, where 1 core, low-power switches with 4
normal, when their performance is not claimed, the processor Samsung combined 4
high on the architecture of the core Cortex-A15 and four energy-efficient
architecture for core Cortex-A7. All are made on a common substrate.
The first group of cores used for processor-intensive tasks,
and the second - for tasks that do not require high processing power. Exynos 5
Octa made on 28-nanometer process technology, as well as a new generation of
Nvidia chip - Tegra 4 .
Samsung sets the processor Exynos, based on the architecture
of ARM, in its smartphones. In addition, she produces for communicators memory
and displays, as well as other components. According to the head of the unit,
which supplies large-scale integrated circuits, in this sense, the company is
unique.
According to estimates of Samsung, the chip, the development
of which is Exynos 5 Octa, is already used in 53 million devices. Processors on
the market for smart phones Samsung is the second largest in the world with a
share of 27%. Qualcomm is in the first with a 42% market share.
