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.

Exynos 5422 has 14.9GB/s for memory bandwidth. Snapdragon 805 is still the king for memory bandwidth with 25.6GB/s after they moved to 128-bit wide interface.
@davidlt
Thanks for that. I think I picked the wrong number (12.8GB/s) for Exynos 5260 instead.
On mid-august 2014 should begin shipping ODROID-XU3 powered by a Samsung Exynos 5422 …
… or there will be a new ODROID XU4 board with Exynos 5430 before ??
I would hope not. There are still rumors/benchmarks with 5433, which should be AArch64 (ARMv8). I doubt that they would name ARMv8 chip 5433, but I hope it’s 64-bit chip. I would hope that ODROID next development board will be 64-bit ARMv8.
