Samsung's Exynos 5 Octa-Core mobile processor has been introduced earlier this year, a Korean based Samsung Electronic and world's famous smartphone maker, now introduced a new mobile processor chip, a "true" Octa-Core processor that have eight cores and will able to use its all eight cores at one time.
Samsung's Exynos 5 Octa is using big.LITTLE technology. However, earlier chip ( comes in Galaxy S4 ) was unable to use its all eight core simultaneously because it have two processors, a Quad-Core Cortex A7 for little task and a Quad-Core Cortex A15 for big tasks that makes four plus four cores is equal to eight cores. But now it is able to use all eight cores for little and big tasks at a time.
The new Eight core Exynos chip with Heterogeneous Multi-Processing ( HMP ) will be ready to deploy in Q4 of this year.
