Samsung has confirmed that it is developing a next-generation version of its Exynos 5 Octa processor, the eight-core chip found in some versions of the Galaxy S4, Digital Spy said.

The South Korean firm took to Twitter to tease an "evolution" of the mobile technology ahead of a full reveal next week.

The Exynos 5 Octa processor is an example of big.LITTLE chipset architecture, with only four cores ever active at once depending on which task the device is carrying out.

Samsung is yet to divulge how the new chip will differ from its predecessor, but it is thought that the clock speed of its cores may be enhanced or support for advanced LTE connectivity incorporated.

Samsung's forthcoming Galaxy Note 3 phablet will be powered by an Exynos 5 Octa processor, likely to be the next-generation version of the tech.

The new hardware is expected to be unveiled at this year's IFA trade show in September.
