The Samsung Exynos 5 Octa chipset has brought a lot of excitement in last CES and the SamsungExynos Twitter account is slowly fanning the flames with little teasing tidbits of info like the image above of the chipset.
It’s a 3D render of the SoC rather than a photo of a production unit. In the same tweet, Samsung is talking up the energy efficiency of the chipset.
In case you missed it, the Exynos 5 Octa uses ARM’s big.LITTLE design. It has two groups of four processor cores – the big group consists of four blazing fast Cortex-A15 CPUs, while the LITTLE group has four power-efficient Cortex-A7 cores. That’s eight-cores in total, hence Octa. Only one of the groups is active at a time, the other goes to sleep (similar to how NVIDIA’s Tegra 3 chipset works, but with more low-power cores).
Samsung claims a 3.3x reduction in power usage thanks to the A7 cores, which are enough to handle menial tasks and are only 13% of the size of an A15 core, so they’re cheap. The overall performance is reportedly the same as an A15-only design. The switch between core groups happens in 30-50ms.

The Samsung Galaxy S IV next Samsung flagship keeps talking about himself.
An image alleged to be of Samsung’s upcoming Galaxy S IV smartphone was published on Friday by SamMobile. If authentic, the image reveals that Samsung will finally ditch its traditional home and navigational buttons for on-screen keys.
The bezel around the device is thinner, giving the upcoming Galaxy smartphone a near edge-to-edge display, similar to Motorola’s DROID RAZR M.
The Galaxy S IV is rumored to feature a 4.99-inch Super AMOLED full HD 1920 X 1080 display, and include a 2GHz quad-core Exynos processor, 2GB of RAM and a 13-megapixel rear camera.
It should be noted, however, that SamMobile could not 100% confirm that the image is authentic. The most recent rumors suggest the Galaxy S IV will be released in April. But with the Samsung Lebanon facebook’s account hinting a realese date to May, we will hear a lot about the GS IV.
In the mean time you should take this rumors with a pinch of salt, until we hear an official word from Samsung.
Samsung’s Galaxy S line of flagships traditionally launches in Q2 – the original launched in June, the sequel in April and the Galaxy S III in May. What about the S IV? A post on Samsung Lebanon’s Facebook account points to May for the Samsung Galaxy S IV launch date.
While we know better than to take anything coming from a Facebook page for granted, we wouldn’t be the least bit surprised if the Galaxy S IV has a May launch (it’s when the S III launched after all).
Earlier, Reuters reported that the S IV will be launching in April, which doesn’t seems slightly less likely, given the enormous popularity the Galaxy S III and Note II are still enjoying.
That’s for the launch date, when the new phone might be announced is a completely different matter. The first two of the line were announced a few months before launch, while the Galaxy S III was announced and launched in May. We expect the forth Galaxy S flagship to follow the footsteps of its predecessor, though, and only go official a couple of weeks before it hits the shelves.
Now if everyone could please stop with the CES/MWC announcement rumors – it’s simply not happening. What we might see at CES though, is tech that will go into the Galaxy S IV like the rumored 5″ 1080p Super AMOLED or a Cortex-A15 based chipset, which are also going around the rumor mill.
Recently, Samsung is rumored to put a quad Cortex-A15 CPU inside the Galaxy S IV with the Exynos 5450 chipset, but EETimes is reporting that the Korean company has a more interesting chipset in the works – the first one to use ARM’s big.LITTLE technology.
This tech pairs a number of powerful Cortex-A15 cores with the same number of low-power Cortex-A7 cores (similar to NVIDIA’s fifth core in Tegra 3). The chipset seamlessly switches between the high and low power cores depending on the load (but it can’t run all at the same time).
The chipset in particular will pack four A15s clocked at 1.8GHz and four A7s clocked at 1.2GHz. The A7s will reportedly match a quad-core Cortex-A8 CPU (not that such exist), while the four A15s should offer a big increase over the already powerful A15 duo that powers the Nexus 10. The chip will be built on a 28nm process and pack 2MB of cache.
We’re sure that there will be plenty of rumors that this will be the chipset in the Galaxy S IV, but it’s more likely to see it in a tablet first.
