http://blog.gsmarena.com/arm-showcas...d-quickoffice/ARM’s videos outline how the true octa-core implementation of the big.LITTLE architecture works when running apps like QuickOffice and Angry Birds. You can actually see when each of the cores is working and how much load it is currently under.
You’ll notice that the four Cortex-A7 cores are quite capable and the more powerful Cortex-A15 rarely have to kick in. Nevertheless, the Samsung Exynos 5 Octa 5420 chipset with ARM’s big.LITTLE MP Kernel can fire all of the eight at the same time if needed.
Here are the two videos below. The platform that the tests were made is features a four Cortex-A15 cores running at 1.8GHz and four Cortex-A7 cores clocked at 1.3GHz. The GPU is ARM’s Mali-T628 MP6.
Hopefully the Note 4 has this cpu.
They should donate 2 cores to Apple.
