It is pretty disappointing that the world's first 8-core mobile processor wasn't really a good one when it was discovered to have faulty design making the whole thing useless. Whilst Samsung Electronics denied that the Exynos 5 Octa 5410 had design issues and if they did do something to "repair" that fault would mean that their factories should also be redesigned for mass producing it (these are the news I was able to read on back when the issue was still hot on the iron). Samsung kept on denying that but it was evident that the system on chip is faulty because I do not think there is a Samsung Galaxy S 4 IV today that is being sold (officially) in a market that is being powered by the Exynos 5 Octa 5410. If there are, then I am pretty sure those are devices that got out of their hands. But anyway, the good thing is, Samsung has done something on that and made the processor even more powerful. Ladies and gentlemen, the Samsung Exynos 5 Octa 5420.
The Samsung Exynos 5 Octa 5420 is based on the ARM Mali™-T628 MP6 cores. According to Samsung, the new processor is 20% better than its predecessor, the 5410. The 5420 is still an 8-core processor and is still following ARM's bigLITTLE philosophy. 2 sets of quad-core processors that actively turns on and off depending on the required power by the phone.
"The newest member of the Exynos family is able to perform General-Purpose computing on Graphics Processing Units (GPGPU) accelerating complex and computationally intensive algorithms or operations, traditionally processed by the CPU. This product also supports OpenGL® ES 3.0 and Full Profile Open CL 1.1, which enables the horsepower needed in multi-layer rendering of high-end, complex gaming scenarios, post-processing and sharing of photos and video, as well as general high-function multi-tasking operations."
"The newest Exynos processor is powered by four ARM Cortex®-A15™ processors at 1.8GHz with four additional Cortex-A7™cores at 1.3 GHz in a big.LITTLE processing implementation. This improves the CPU processing capability by 20 percent over the predecessor by optimizing the power-saving design"
