Samsung has updated its Exynos 5 Octa mobile and tablet processor, claiming it now offers twice the 3D graphics processing power of its predecessor.

The new Exynos 5 Octa, announced yesterday, will be the first production-ready processor built on ARM's latest GPU (graphics processing unit) architecture. Samsung previously used a GPU design by rival British firm Imagination in the last version of the Exynos chip.

The new processor is based on ARM's big.LITTLE infrastructure, offering four Cortex A15 cores clocked at 1.8GHz and four Cortex A7 cores at 1.3GHz. The revamped processor is said to boost the CPU (central processing unit) capability by 20 per cent.

The South Korean giant said that it's been seeing increased demand for high-end graphics processing and believes that the new octa-core chip will help deliver this, while also decreasing power consumption on devices.

The previous version of the processor, which came with Imagination's GPU, has been around for months, but it's only been available in just a few of the company's products, including certain versions of the Samsung Galaxy S4.

Samsung has not revealed which devices will be powered by the updated Exynos 5 Octa processor but it did say that it is currently sampling the technology with a number of customers.

The new processor is set to go into mass production next month.
