Samsung Release Details of the Octa-Core Exynos 5420 Processor


After teasing the news last week, Samsung officially unveiled the Exynos 5420, the latest processor in its line of Exynos 5 Octa eight-core processors. The new processor offers twice the 3D graphics performance of the 5410 thanks to a new ARM Mali graphics chip, as well as a general performance that’s about 20 percent better, according to Samsung.


Like the Exynos 5 Octa processors before it, the Exynos 5420 comes equipped with two sets of four cores. Four ARM Cortex-A15 cores clocked at 1.8GHz handle the tougher jobs, while four Cortex-A7 cores clocked at 1.3GHz handle easier tasks. However, unlike previous models, the Exynos 5420 may be able to run all eight cores at once for more demanding tasks. The redesigned eight-core CPU also fixes an issue with the Exynos 5410′s CoreLink CCI-400 that hurt performance and drained battery life quicker than expected.

The Exynos 5420 will be available starting in August, but we probably won’t see it featured in a smartphone until the Galaxy Note III makes its debut. Samsung is expected to announce the third-generation phablet in early September during IFA expo in Berlin.
