Samsung is reportedly developing a new ARM Cortex-A15-based SoC (system-on-chip) that may very well power its next flagship smartphone.
The processor, dubbed Exynos 5440, was unearthed on Samsung’s Kernel Git page, adding fresh credence to rumours that the handset unofficially dubbed the Galaxy S4 will rock an Exynos 5 series chipset produced using a more energy-efficient 28nm manufacturing process.
The exact clock speed or GPU details of the 5440 were not revealed. So it’s not clear how this SoC differs from the 5450 we reported previously, which is also said to feature four Cortex-A15 cores (plus an eight-core GPU) and is thought highly likely to feature on the S4.
What’s probably a given, though, is whichever chip makes the cut is almost sure to be of an A15 variety. There’s also a good possibility that it’s based on ARM’s ‘big.LITTLE’ architecture that combines a two quad core A15 and A7 clusters together, with the aim to deliver high performance with the former and conserve battery life with the latter.
Other additions mooted to be on board include a 13-megapixel camera that was allegedly left out of the Galaxy S3 amid supply shortages and a 4.99-inch full HD display with a Retina-beating 441 pixels per density.
