Details on Samsung’s Exynos 5433 Processor & Possible inhouse Graphics Processor
Samsung has had a busy month with the launch of their new flagship Note 4 which has a variant which is supposed to come with the Korean company’s own Octa-core Exynos 5433 processor. However, when it comes to the details regarding the processor, there has been little to no information which is readily available. However, details are beginning to emerge thanks to the good folks over at AnandTech.
According to AnandTech, new sourcecode of the Exynos 5433 reveals that Samsung is using ARM’s new Cortex A57 & A53 chips in their big.LITTLE configuration of the Octa-core processor. The big.LITTLE configuration is a core architecture developed by ARM which puts a larger, more capable, less energy efficient core with a smaller, less capable, more energy efficient core which allows the core to adjust to needs of the device dynamically between the two cores. This leads to better battery life and increased performance – two things many of us want in our devices. The significance of the usage of the two processors comes when you look at some of the previous rumours which hinted that the newly announced Exynos 5433 would use the Cortex A15 and A7 instead. The combination of the A57 & A53 processors will allow for better performance and better battery optimizations compared to the relatively dated A15 & A7 combination.
Another item which came up in AnandTech’s article, is the fact that the Exynos 5433 is capable of 64-bit processing, something Android L is able to take advantage of. However, Samsung did not tout the Exynos 5433 as a 64-bit processor instead they chose to label it as a more powerful 32-bit processor. The reasoning behind this, it appears, is due to the 64-bit capabilities being “turned off” by Samsung from the get go. This limits the processor to its 32-bit architecture. However, while unlikely, it is possible that Samsung could implement the 64-bit architecture later on when the Note 4 receives Android L.
The Exynos 5433 processor is coupled with ARM’s latest Mali T760 graphics processor which will be running at 700 MHz, the highest speed yet when it comes to mobile graphics processors from ARM. This promises to bring quite a hefty bit of graphic capacity to the Exynos 5433 which we have seen in recent benchmarks.
In addition to this, it looks like Samsung maybe on its way to start producing its own in house graphics processor. In the months preceding the launch of the Galaxy S5, rumours began surfacing of the Korean behemoth beginning development on producing its own in house graphics processor to complement its Exynos line. According to recent reports, Samsung has managed to hire engineers from companies such as NVIDIA, AMD, and Intel among others. These companies are quite obviously some of the front runners in the chip fabrication industry. In addition, it has also surfaced that Samsung has been developing its own graphics processor for a few years prior to rumours surfacing.
