Months into its rumoured September release date, the Galaxy Note 3 will likely get an upgraded Exynos Octa 5 CPU as Samsung announced this week the completion of major reworks for the chip architecture.

The reengineer, according to the Asian tech giant, will deliver four 1.8GHz ARM Cortex-A15 processors and four 1.3GHz Cortex-A7 cores to the system, boosting its processing might by 20 per cent.

Also, the revision improves Exynos' GPU muscle by 100 per cent while maintaining its reputed power-efficient characteristic, which should afford extended operating hours to devices that the processing system will power.

According to CNET, Samsung has yet to identify the specific Galaxy devices and models that the new Exynos chip will fire up though the company indicated that volume production will commence anytime in August.

The time frame suits with the purported Galaxy Note 3 unveiling, which reports said will likely happen on September 4 with the actual release date to follow shortly in the immediate weeks.

Last week, leaked specs of the third-generation phablet surfaced, suggesting that like the Galaxy S4, the Note 3 will be served in two CPU flavours - a new Exynos 5 Octa chipset or a 2.3GHz Snapdragon 800 processor. The deployment will hinge on market destination.

Display screen attributes point to a Full HD resolution of 1920 x 1080 with Super AMOLED technology, which according to BGR News has been confirmed by Samsung. However, the screen size remains a mystery with some reports claiming that from the 5.5-inch seen in the Galaxy Note 2, it will be stretched to 5.99-inch.

But there were claims too that the Note 3's viewing window is capped to 5.7-inch.

On release date, Samsung is expected to unwrap a Galaxy Note 3 that boasts of a 13MP main cam shooter, a 3GB of RAM, an enhanced S-Pen stylus and possibly Jelly Bean 4.3, which according to reports, Google is set to unleash in August.
