CES 2013: Eight-core A7 and A15 mix


Detailed back in November last year, Samsung's new eight-core Exynos is now official. Samsung announced the new mobile SoC based on the big.LITTLE configuration during its second-day keynote at CES.

Based on two quad-core clusters stitched together, the 28nm Samsung Exynos 5 Octa is not your standard eight-core chip as it either uses more powerful 1.8GHz clocked Cortex-A15 or more power effective 1.2GHz clocked Cortex-A7 cluster for standard workloads. Samsung noted that it has managed to cut down the power consumption by up to 70 percent when compared to the Exynos 5 Dual and since it comes with four Cortex-A15 (as opposed to two in the Exynos 5 Dual), it provides much higher CPU performance and twice the 3D performance of any currently available mobile processor, including the Exynos 4 Quad.

As you remember, the Exynos 5 Dual was doing quite an impressive job in the Google Nexus 10 tablet and Exynos 4 Quad was more than enough for the Galaxy Note II and the Galaxy S III.

Unfortunately, Samsung did not mention any time frame or actual devices that could feature the new Exynos 5 Octa but we guess that MWC 2013 in February might bring some new details.

This is Awesome!! but lets Clarify some stuff... : )  

There seems to be a lot of confusion over this one. To clarify, this isn't an 8-core chip, its a 4 core big.little chip.


That means even though the silicon has 8 cores on it, to the user (and to apps), it looks and behaves like a 4 core part. When performance is needed, the 4 high performance cores are used. When it isn't needed, the 4 low-power cores are swapped in (or you can be running any combo of high perf/low power cores). But you are never running more than 4 cores at a time.

Since the high power and low power cores run on the exact same instruction set, they can be swapped in on the fly without the app really knowing. Its neat, but probably gross overkill. Future processor versions will most likely just dynamically disable parts of the processing and instruction pipeline, but that takes a while to get right.  Gosh dammit i love competition !

@DJJS7 Just watch the video interview with ARM's president where he discusses Samsung's Exynos Octa. In a nutshell, it's a true 8-core where all cores can be utilized with logic assigning the demanding threads such as immersive games to the high performance A15 cores and the non-demanding threads to low power A7 cores.
