Samsung first introduced the Exynos 5 Octa processor back in January by touting its ARM big.LITTLE infrastructure that was smarter at delivering quad-core performance without taxing the battery too much. Samsung today announced that the latest Exynos 5 continues those goals but also enhances graphical performance.

The new 5420 level of the Exynos 5 Octa has two quad-core processors present that divide work based on activity. The 1.8 GHz ARM Cortex-A15 cores are the more powerful but also use up more energy, so the system sometimes favors the 1.3GHz Cortex-A7 cores because they are lower power but can still deliver very good performance for less demanding activity. Samsung claims that this architecture is 20 percent more energy efficient than the previous processor, and 70 percent more efficient than if only the Cortex-A15 cores were present. Instead of using the high-power cores for simple activities like listening to music, the big.LITTLE setup is able to perform that same task and conserve energy to keep music playing for a longer period of time.

Samsung upgraded the Exynos 5 Octa to have an ARM Mali-T628i GPU, which is twice as fast as the previous Exynos. This can allow game developers to be more ambitious in their game design and build more detailed graphics because the phone or tablet will be able to handle more complex 3D gaming. When NVIDIA upgraded from Tegra 2 to Tegra 3, many games were playable on either processor, but games like Riptide had richer graphics that allowed for splashing water and smoother movement. with improved graphics in the new GPU and more efficient use of its processors could lead to better gaming options and enhanced media creation like editing videos or photos on a mobile device.

Exynos 5420 raises the clock speed of the Cortex-A15 and A7 cores, increases the memory to 14.9GB, and upgrades the graphical capabilities compared to what was seen on the Exynos 5410 earlier this year. These are definitely welcome upgrades, but the question is what device can users expect to see the new Exynos debut? I can think of one good place for Samsung to start.
