Samsung unveils beefed up Exynos 5 Octa 5420 as Galaxy Note 3 launch looms

Samsung has unveiled the latest addition to its popular Exynos chipset family, the Exynos 5 Octa 5420, prompting speculation that the Galaxy Note 3 could well feature an 8-core SoC.

Like its predecessor, the Exynos 5 Octa 5410, the 5420 will be based on ARM's big.LITTLE processing architecture, featuring four low-power Cortex-A7 CPUs clocked at 1.3GHz and four beefier Cortex-A15 CPUs running up to 1.8GHz.

Perhaps more importantly, the new Exynos 5 Octa 5420 will offer a vastly superior graphics set-up, featuring a six-core ARM Mali T628 GPU with 3D capabilities "over two times greater" than the first Exynos 5 chipset.

According to Samsung, the new Exynos 5 SoC will be oomph-y enough to facilitate "desktop-quality" video editing, as well as supporting 1080p video playback at 60fps.

Again, such capabilities sound like a boon for the future Galaxy Note 3. Samsung often talks up the productivity and professional benefits of its flagship phablet, and recent rumours have pointed to the device sporting either a 5.7in, 5.9in or even a 6.3in Full HD display.

At the same time, some speculation has it that Samsung may favour a Snapdragon 800 SoC for the Note 3 under the hood. Other gossip points to the Korean firm's next phablet coming with a 13-megapixel primary camera.

We'll likely know more in just over a month, when the annual IFA extravaganza descends on Berlin - as usual, we'll be heading over to Germany to cover the Teutonic blockbuster every step of the way.
