Samsung Galaxy S4 Performance Boosted By 10% After Software Update

This is what we are expecting from Samsung and rumors are claiming that they are working on it and preliminary benchmark show an improvement by almost 10% of the smartphone, after the new software was installed on the Galaxy S4. Samsung Galaxy S4 must be one of the most controversial smartphone in 2013, and that’s because they have decided to ship the smartphone with two different processors. And this Qualcomm Snapdragon 600 versus own made Exynos Octa processors is the cause of all controversies as users don’t know which one to pick, for the best performance. And it’s not like they have to choose, because Samsung spread the smartphone by regions, and you are in a way or another forced to buy the flagship smartphone that Samsung attributed to your region.

Even if early benchmarks showed that the difference between these two processors is very small, with a plus for the Octa Core processor from Exynos, and the press release from Samsung which disapproved any notable differences between the two processors, now that Samsung is working on a software that will improve the performance, the question comes again: Will the difference be more obvious now?

First of all, the software is planned to be released this summer and will have different release dates depending of the region and carrier, but in the same time, Samsung might be tempted to do a tweak to Octa Core processors so that they won’t be more powerful than the Qualcomm quad core. But this is just my opinion, don’t take it as granted, as it’s definitely not going to happen. Or…is it?

Well, in order to get the big picture we must look deep in the problem and analyze the exact differences between these two processors. Snapdragon 600 is a quad core processor, which means it is using all cores to process the information, while Exynos Octa has eight cores, grouped in two parts. One quad core chip which is using the Cortex A7 technology and is known for quite low performance but great for battery life, as it uses less energy while the other chip is formed by quad core built on Cortex A15 technology, which is very bad for battery life but offers excellent performance levels. The trick Samsung made, in order to equalize these two different processors was that they have cancelled four out of eight cores on the Exynos, so that at any time, only four Cores would work, while the other four wait in standby mode.

Exynos Octa models, in standby and when used a little bit, are using the A7 cores, and when you start doing multiple tasks or run programs which ask for more resources, then the A7 cores shut down and A15 come in action. From this example we can clearly see that another difference appeared between Exynos and Qualcomm processors: Galaxy S4 equipped with Exynos will have a longer battery life, beside the obvious performance which can be activated in case Samsung decides to power all eight cores at the same time trough the software they are preparing.

But in the end, Samsung is going to roll out the software with no huge difference between processor models, and maybe from future models like Galaxy Note 3 the idea of activating all eight cores will become more realistic. Otherwise all the controversial ideas about Galaxy S4 will feed up a huge complain from customers who bought the Qualcomm model and this would put Samsung in a very bad situation to the point of loosing good customers who spent lots of money on their latest technology.
