Meet the new and improved Exynos 5 Octa processor, designed to bring enhanced graphics performance and energy efficiency to the next generation of high-end smartphones and tablets. Advanced ARM® GPU Compute technology and a suite of power-saving features allow our latest processor to run complex applications while conserving battery life - because a mobile device isn't really mobile if you have to worry about charging it all of the time. We'll fill you in on the most important specs for this new SoC and give you an idea of what to expect from future devices that run on it.

Enhanced Graphics with New ARM® Mali™-T628 GPU

The new Exynos 5 Octa (5420) packs an ARM® Mali™-T628 GPU, which is powerful enough to support 3D graphics processing that's more than twice as fast as the Exynos 5410, for smoother rendering and diminished lag times. The Mali-T628 is also capable of GPU Compute functionality, meaning it can perform general-purpose computing and intensive tasks to help alleviate the CPU's workload and speed up processing times. In combination with big.LITTLE architecture, GPU Computing significantly increases power efficiency for noticeably better battery life. OpenGL® ES 3.0 and Full profile OpenCL™ 1.1 support provide the additional power that's needed to render high-quality, complex gaming scenarios and handle comprehensive photo and video editing.

Making Advanced Applications Possible

GPU Compute technology was once limited to PCs and other desktop devices, but ARM® Mali GPUs are bringing this functionality to mobile. There are a lot of advantages associated with GPU Computing that will open up opportunities for innovative applications on mobile devices that use the new Exynos 5 Octa (5420).

  • Video and image stabilization and editing – Get creative! Edit photos right after you take them or apply filters to live video directly on your smartphone.
  • Facial detection - Refined facial recognition allows for enhanced security features and content restrictions for children.
  • "Open eye" detection - You won't have to retake nearly as many photos if your smartphone's camera only captures an image when everyone is looking at the camera.

Increased Power Efficiency for Extended Use

The new Exynos 5 Octa (5420) features four 1.8GHz ARM® Cortex™-A15 cores and four 1.3GHz Cortex™-A7 cores in an optimized big.LITTLE™ configuration. This power-saving design provides 20% increased CPU performance over the previous version of the processor, but with 70 percent greater energy efficiency than Cortex-A15 cores alone. The system switches amongst eight cores of Cortex-A15 and Cortex-A7 processors depending on workload, selecting the right core for the right task and saving power in the process.

If you're an avid mobile gamer who's into FPS games with complex graphics or fast-paced, high-frame-rate racing games, the "big" Cortex-A15 cores are there to do the heavy lifting. Even if gaming isn't your thing, you'll notice faster page loading times and better graphics quality when browsing websites with high-quality media. Big.LITTLE technology is all about balance, so the "LITTLE" Cortex-A7 cores step in to take care of lighter workloads, like pulling up work emails, playing music and texting. The Cortex-A7 series is the most energy-efficient processor that ARM® has to offer, helping your device go longer between charges so you can stay connected while you're busy living life.

All of you Photoshoppers and Instagram addicts will be happy to hear that the Exynos 5 Octa (5420 ) also features Mobile Image Compression (MIC), which lowers the system power required to bring photos from memory to your screen for processing. This means photo-editing doesn't unduly impact battery life, and you can get the maximum use out of your mobile devices with high-resolution displays.
