Korean electronics giant Samsung has released more exciting details about its next-generation Exynos dual-core processor for mobile devices, which will be twice as fast as comparable Exynos chips currently used in its smartphones and tablets.

The new dual-core, 1.7GHz chip is the first on the market to feature ARM's new Cortex A15 CPU , which will deliver significantly improved performance over the Cortex A9-based chips found in most smartphones and tablets currently on the market. Moreover, the new chip will also consume 30 percent less power than existing Exynos chips, Samsung noted on its Web site.

Samsung's Exynos chips power a range of Galaxy smartphones and tablets. The Galaxy Note 10.1 tablet, for instance, will come later this month with a quad-core version of the Exynos 4 chip.

The Exynos 5 Dual chip, however, will provide far better multimedia performance than its predecessors. According to a Samsung blog post, the next-generation Exynos mobile processor will allow mobile devices to display images at a 2560 x 1600-pixel resolution, and can help devices play back full 1080p high-definition at 60 frames-per-second (fps), which is double the normal rate.

As tablets and smartphones are increasingly used for entertainment and gaming, displays are playing an crucial role. Apple's latest iPad, which also packs an ARM processor and an Imagination Technologies graphics processor, features a high-resolution Retina display that can deliver images at a 2048 x 1536 pixel resolution.

Meanwhile, the Exynos 5 processor uses an ARM Mali T604 graphics processor with four cores, allowing for more efficient screen refresh rates when reading e-books or Web pages, thus helping save power, noted Samsung. The chip will also come with support for USB 3.0, which means we could soon see smartphones and tablets with USB 3.0 ports for fast data transfers.

Much like the latest Exynos dual- and quad-core chips based on Cortex A9, the Xynos 5 chip will be based on the 32-nanometer manufacturing process. Several companies including Qualcomm are already having chips made using the 28nm process.

Samsung did not detail when it plans to pack the latest processors in mobile devices, but the chips are being manufactured already. ARM said it expects the first Cortex A15 devices to arrive early next year, while Texas Instruments has already announced OMAP 5430 and 5432 chips based on Cortex A15. No mobile devices have been officially announced for the Exynos 5 Dual, and no release date has been announced for the first Cortex A15-powered devices.
