Samsung goes for the throat with its 8-Core Exynos 5 Octa
Just when we were finally getting used to the notion of quad-core processors in our smartphones and tablets, Samsung is dropping a bombshell on the mobile community: an eight-core processor. In this particular case, however, there are two banks of quad-core processing units. The first bank consists of four Cortex-A15 processing units for high performance, while the second bank consists of four Cortex-A7 processing units for lighter workloads in order to save battery life.
The idea of using lower-power cores for mundane tasks sounds similar to what NVIDIA does with its Tegra 3/
Tegra 4 processors
. The Tegras feature quad-cores for high-performance applications and a fifth "companion" core to handle loads that aren't as demanding.
According to Samsung, going with this "high-low" 8-core arrangement allows it to offer 70 percent greater power efficiency than the previous generation quad-core Exynos.
“The new Exynos 5 Octa introduces a whole new concept in processing architecture…designed for high-end smartphones and tablets,” said Samsung's Dr. Stephen Woo. “When you want multiple applications to perform at their best, you want the best application processor currently available—the Exynos 5 Octa.”
Could we possibly see this new chip in a Samsung Galaxy S IV???

It also almost twice as high in the practical Browsermark and SunSpider benchmarks, as well as practical GPU benchmarks.
Fact of the matter is that adding more cores means very little if the hardware and software isn't going to really take advantage of them. It is just a bulletpoint "feature" with no practical use, except maybe to do well in synthetic benchmarks with little reflection in real-world performance.
