Overall there have been far fewer surprises than we had hoped for at this years Mobile World Congress, but one nice surprise which many may have missed is that ARM are showing off a prototype Samsung tablet running the Exynos 5 Octa chip. The 5 Octa was first unveiled at CES, but it’s only now at MWC we can actually see the chip in action.
The 8-cores are split in to 4 Cortex-A7 cores and 4 Cortex A-15 cores, which can instantly turn on and off, or share processes depending on the task. Engadget have a video here, which shows the tablet in action and how the cores switch depending on what is required. For example complex graphics are handled by the A15 portion of the chip while video playback goes to the A7 side.
The idea is that the 5 Octa will not only be powerful but also be more efficient, with claims that power usage could be cut as much as 50% depending on how you use a Exynos 5 Octa device.
