Samsung in 'final stages' with a 64-bit Exynos processor, prime candidate for the Galaxy S588
After it became clear that Samsung is still producing the A7, and the Koreans chimed in they are all for doubling the mobile chipset bits, it was a matter of time before we learn such an Exynos is indeed in the pipeline, and we might see it in the next flagship, the Galaxy S5. This chip is meant for smartphones as well as tablets, said the Samsung source, cited by the publication.
The 64-bit architecture has its advantages before the 32-bit, and these are not only the much higher amount of addressable RAM it allows, but also multitasking and overall productivity shenanigans. Its power will really shine when software gets written from the ground up to take advantage, and what better way to push developers than actually have flagship phones and tablets with the tech already on the market.
