Samsung already have a few octa-core big.LITTLE SoCs part of Exynos 5 Octa family with Exynos 5410, Exynos 5420, and Exynos 5422/5800, all based on 28nm process. The company has just announced a new Exynos 5 Octa processors with Exynos 5430, but this time manufactured using 20nm High-K Metal Gate (HKMG) process technology providing 25% less power consumption compared to 28nm Exynos SoCs.
Exynos 5430 SoC will feature four ARM Cortex A15 cores at 1.8 GHz, four Cortex A7 cores at 1.3 GHz, supports WQHD (2560×1440) and WQXGA (2560 x 1600) displays using hibernation display and Mobile Image compression (MIC) in order to lower power consumption. It also said to support HDMI, come with a Multi Format Codec (MFC) supporting HEVC/H.265 decoding, as well as an enhanced dual ISP, and up to 17GB/s of memory bandwidth. That’s about all the information I could get at this point. The CPU core frequencies are lower than Exynos 5422, but the maximum memory bandwidth appears to be higher (17GB/s vs 14.9GB/s), and of course the power consumption is significantly lower. It will also be found in the recently announced Galaxy Alpha smartphone.
More details should eventually surface on Samsung Exynos 5430 page.
