A few months back, Samsung debuted its latest Exynos 4 quad core mobile System on a Chip (SoC) based on four Cortex A9 cores. The company recently released details of its next generation Exynos processor, only this time it is a dual core variant. The Samsung Exynos 5 Dual (Exynos 5250) is packing the latest mobile ARM technology with two ARM Cortex A15 CPU cores and a Mali T604 graphics core.

The dual core processor is running at 1.7 GHz and features the NEON fixed function hardware for accelerated video decoding. Further, the Mali T604 GPU is based on ARM’s new Midgard architecture. The T604 includes a unified shader design with support for OpenGL ES 3.0 and the full OpenCL 1.1 profile. Not too shabby for a mobile GPU!

The Exynos 5250 also sees an upgrade (from 6.4 GB/s in the Exynos 4) in memory bandwidth to 12.8 GB/s between the processor and two port LPDDR3 memory at up to 800Mhz. The increased memory bandwidth along with the new–and more powerful–processor and graphics hardware enables Samsung to offer support for much higher resolution displays up to WXQGA or 2560x1600 pixels.

Other features of the new Exynos 5 dual core processor include USB 3.0 support, wireless display support, and a claimed ability to playback 1080p video at 60 FPS using Google’s VP8 video decoder (no word on H.264 performance, though the ARM processor’s NEON hardware should handle those videos well enough). The GPU is also able to allegedly use 20-times less power when displaying a static image (such as a web page or ebook page) called PSR mode.

According to the Android Authority, the first product to be powered by the new Samsung Exynos 5 processor will likely be the company’s upcoming Galaxy Tab 11.6 tablet. Quad core variants of the Exynos 5 should come out following the successful dual core launch.

The Cortex A15-based mobile processor is packing some impressive specifications, and it will be interesting to see Exynos 5-powered devices. Specifically, it will be interesting to see how it stacks up compared to products like NVIDIA’s Tegra 3, TI’s OMAP 5, and even Samsung’s own Exynos 4 quad core SoC. Are you excited about the new dual core SoC?

I still like 4 core with 2gig Ram But better support for graphics and other features.
Maybe easier developing for their phone.
Anything easier and more flexible is appreciated.
I like that they added OpenGL 3.0 to it.
I am not excited about this phone.

I like the USB 3.0 support, but I hope, if you benchmark this in any tablet or device that uses this processor, that you test the USB with Cheep USB 2.0 thumb drives, Then more expensive USB 3.0 thumb drives be sure to use 64 gig thumb drives and transfer files that are at least as big as the space available on the drives after they are formatted. Please try as much as possable to max out the USB bandwith on any tested device that USES USB 3.0 to see if the device is able to get close to the advertised bandwidth (less overhead). There are loads of 64 gig USB thumb drives on the market for less than $40.00 and thats what most can now afford. Problem is, in many devices the USB 3.0 device drivers are not performing very well with USB 2.0 thumb drives. My ASUS U56E's USB 3.0 port does not play nice with with USB 2.0 thumb drives, even after I installed the most up to date driver software. Please Stress test mobile devices like you test High performence gaming rigs.
