Here is the official video demonstration and overview of the Samsung’s first 8-core processor – the new Exynos 5 Octa with ARM big.LITTLE technology.
As we have noted, the new Exynos 5 Octa processor is based on two groups of four cores – Cortex A15 for maximum performance and Cortex A7 for everyday tasks. This approach allows the company to reduce the energy consumption by up to 70% compared to the dual-core Exynos 5 Dual, which relies on Cortex A15 chip.
LITTLE – Cortex A7:
Most energy-efficient applications processor from ARM
Simple, in-order, 8 stage pipeline
big – Cortex A15:
Highest performance in mobile power envelope
Complex, out-of-order, multi-issue pipeline
The best of both – seamless pairing of Cortex A15 and Cortex A7:
