Samsung Exynos 5 Octa 

Announced January, 2013
  • 1.6 GHz
  • Octa core

Both the CPU and GPU are designed by ARM, who changes their GPU architecture every five years or so.

Samsung has a new Exynos 5 Octa SoC

by Peter Scott |
It features ARM’s new six-core Mali T628 graphics and to the best of our knowledge it is the first SoC to use the new GPU.
A new superphone perhaps, or a proper tablet, with a 2560x1600 screen, as the GPU appears to be optimized for that particular resolution.

Samsung Updates Exynos 5 Octa (5420), Switches Back to ARM GPU

by Anand Lal Shimpi |
The biggest question about the new Exynos 5420 is whether or not the cache coherency issues have been worked out.
Part of the problem with the design was a broken implementation of the CCI-400 coherent bus interface that connect the two CPU islands to the rest of the SoC.

Samsung releases more details on their new Exynos 5 Octa processor

by Anthony Garreffa |
Samsung are claiming that the refreshed 8-core SoC features 20% more CPU processing power, too.
The new refreshed 5420 variant of the SoC is based on Mali-T628 MP5 silicon and features four ARM Cortex-A15 cores running at 1.8GHz and four 1.3GHz Cortex-A7s in an ARM big.
Thankfully, this problem can be resolved by simply updating the kernel so the Exynos 5’s eight physical cores operate in tandem and allocate more demanding tasks to the chip’s more powerful cores.
LITTLE driver, whereby the Linux kernel doesn’t differentiate between the various architecture based cores, and the following takes place.
