Samsung 8-core Exynos 5 Octa mobile processor
Samsung is announcing a new 8-core processor, but it's not quite what you'd think. It's better, reports the verge. The new silicon is called the Exynos 5 Octa, and it uses ARM's new big.LITTLE processor technology. The processor design switches between two clusters of four cores each: ARM Cortex-A15 for performance, and Cortex-A7 to handle common workloads while providing better battery life. Samsung said it is focusing on three areas: processing, memory and display technology.
This isn't even the first chip to use separate cores for heavy and light workloads. But Samsung says that it can cut power consumption by up to 70 percent compared to the Exynos 5 Dual by being able to tackle common jobs with the lower-voltage A7 cores, which means — far more than the Exynos 5 Dual — we could see it fit inside smartphones. And since it has four Cortex-A15 cores, the Exynos 5 Octa stands to outclass that existing Exynos 5 Dual, the dual-core-A15 processor found in the Nexus 10 — already an extremely fast chip — and Samsung says it provides twice the 3D performance of any previous mobile processor, including the company's Exynos 4 Quad.
Samsung’s Exynos 5 Octa is comprised of two sets of four cores: ARM Cortex-A15 and and Cortex-A7, and is said to lower power consumption by up to 70 percent compared to the Exynos 5 Dual.
The Exynos 5 Octa is expected to be made available in high-end smartphones as it is expected to make multitasking on mobile devices a smoother experience as there should be no stuttering when playing HD videos. The Exynos 5 Octa also has twice the 3D performance of any of Samsung’s previous mobile processors and is the first mobile processor to implement ARM’s big.LITTLE technology. So what does all of this mean to you, the average and above-average mobile-device user? Simple – expect your mobile devices to get some serious speed and 3D graphic improvements if it’s built with the Exynos 5 Octa.
We're definitely looking forward to seeing if Samsung can deliver better battery life and better performance (if not simultaneously) in the next generation.
If this goes into the Galaxy S4, daaaamn.

The fifth Tegra core is an A15, so we'll see just yet.

One word: OVERKILL lol.
I don't understand why they didn't just drop the Cortex A7 to a dual core, if the Cortex A7 is meant to be a low power part, why does it need to be quad core? I understand the A15 being quad core but not the low power one...
Also, Tegra 4 does have one advantage up its sleeves that no one else has, it's that "One Shot HDR". No one else seems to have it yet...

Yeah, I thought exactly the same - 5th low-power core makes sense in phones, as well as Intel's HT. But packing 8 cores in a phone? When even 4 cores in desktops are rarely utilized properly?
Regarding 1-shot HDR, it's a known technique which involves multiple exposures on 1 click - it can be achieved with several subsequent exposures or just reading the data and extending exposure time (the latter is troublesome but gives lower movement-related errors). Unless NV patented it, it's not that difficult to achieve. I believe SGS4 will have such feature, perhaps not exactly as in NV implementation, but it should be present.

I can't imagine having a cell phone with an 8 core processor. A Tablet however would benefit from more horsepower.
It's all about the OS not the processor. Look at the upcomming BB10 phones the dev devices are dual core and snappy as hell.
Even Apple realizes this as they are currently building IOS7 from the ground up possibly as a Microkernel OS. IOS and android and Windows 8 are horrible for mobile devices from an efficiency perspective.

Its the next step in developing mobile PC so yeah where these devices will take over desktops. Seriously I rather see tech development on batteries for these portable devices.

Probably won't be too long before someone makes an ARM F@H client and builds a Galaxy folding farm.
