Samsung Galaxy S4 and the Exynos 5 Octa 8-core CPU: What You Need to Know



Although it told Pocket-lint that UK handsets would feature the company's own 1.6GHz octa-core Exynos 5 CPU, during its launch event in New York on 14 March, and reinforced that claim in its press release, it has now been confirmed that we will be getting the Galaxy S4 powered by the 1.9GHz quad-core Snapdragon 600 processor instead.




Samsung Galaxy S4 May Use Exynos 5 Octa 8-core Processor




However, we previously understood the benefits of the octa-core processor to be relevant to power management, being able to switch to the second set of four cores in order to offset less power-hungry processes. Many suggested this would help with battery life.


The Exynos 5410 processor of the Galaxy S4 octa core is not able to turn his eight cores simultaneously for reasons of safety. It can only use its four 1.6 GHz Cortex-A15 cores or four 1.2 GHz Cortex-A7 cores at a time, according to the workload. But the HMP technology allows Galaxy S5 Exynos 5422 to run all the eight cores of processor simultaneously during high utilization. Thus (42.1 + 41.5 GHz) Exynos 5422 Galaxy S5 has taken a lead over (42.5 GHz) Snapdragon Galaxy S5, especially in the CPU department. 2ff7e9595c
