While the Samsung Exynos 5 Octa chips come with eight cores (four Cortex A15 and four Cortex A7), only four of them can work at executing a task at a time, making it effectively a quad core solution. That might change soon though, as Samsung has announced its Heterogeneous Multi-Processing (HMP) solution for the Exynos 5 Octa chipsets. In simple words, the new solution allows for all eight cores to run simultaneously.
“An eight-core processor with HMP is the truest form of the big.LITTLE technology with limitless benefits to the users of high-performance, low-power mobile products”, said Taehoon Kim, vice president of System LSI marketing, Samsung Electronics. Software threads that require more CPU horsepower would be transferred to the Cortex A15 cores, while the less demanding applications would be handled by the Cortex A7 cores simultaneously, thus improving performance and efficiency.
We’ve heard MediaTek talk about something similar in the past, with the company’s true Octa Core CPU to hit the market in November.
Samsung hasn’t announced whether it would be implementing HMP to its existing line up or not. If it does, we should see Galaxy S4 and Note III getting a significant performance boost. The company expects to roll out the HMP solution sometime in Q4. Perhaps, this was the big evolution for the Exynos chips Samsung was talking about not so long ago.
