Samsung announces 8-core Exynos 5 Octa mobile chipset

At CES 2013 we've seen both Qualcomm and NVIDIA announce impressive new mobile chipsets and now to round out the major three manufacturers we have Samsung showing off a new Exynos processor. While it's not an entirely new generation of silicon, the new Exynos 5 Octa chip is set to bring interesting performance and battery life gains over the Exynos 5 dual CPUs that are already in the market.

While this chip is technically an eight-core processor, it's actually four ARM Cortex-A15 CPUs paired with four ARM Cortex-A7 CPUs; the former for high-powered tasks and the latter for saving battery. The chipset uses ARM's reference big.LITTLE processor switching technology, will switch between the A15s and the A7s depending on the performance needs of the tasks, allowing for greater performance over Exynos 5 Dual chips, but also longer battery life.

The Exynos 5 Octa should also be more efficient thanks to a slight die shrinkage from 32nm HK-MG (in the Exynos 4 and Exynos 5 Dual) to 28nm HK-MG. Clock speeds of the cores aren't known at this stage but the GPU inside should stay as the Mali-T6xx series (although the exact model wasn't confirmed). Samsung also neglected when we'll see this chipset in any new devices but well place bets that it'll turn up inside the next Galaxy flagship.

This chip supports 24bit audio which is studio quality Audio. Why can't all the other phones have this amazing capability?

So, it would be similar to Tegra's 5th core. But instead of 1 Cortex-A9 it will utilize 4 Cortex-A7. Guess what will have better battery consumption. Under full load it still will utilize just 4 Cortex-A15, same as Tegra 4. So same performance as Tegra 4, other is just pure marketting...
On another hand it could utilize Cortex-A7 not just in standby. It would be enough for daily life tasks without games and software video decoding. So Cortex-A15 could work only in games unlike with Tegra 4, where single Cortex A9 wouldn't be enough for daily life tasks.

Tegra 4 uses 4xcortex a15 + cortex a7, not cortex a9.

the new intel bay trail uses a smaller process(22nm) and trigate transistors. it will smoke this pretty bad.

This would be great for linux and possibly windows rt/windows phone 8 but android doesn't use 4+ cores well at the moment, lets hope google improve android this year.

Android's SMP support is apparently shoddy at best, anyway, so there's still plenty of room for improvement even on Dual Core devices.

Supreme performance, yes.
Supreme battery life, we'll see.

Did you not read the article? This new technology is precisely meant to save battery, through using less juice hungry A7 cores for lower computing power processes, while reserving the A15s' muscle for complex tasks. Not all cores will be used when the device is idle anyways.
