We got cosy with a prototype of the Samsung Exynos 5 Octa tablet, one which was demoed on ARM’s booth to showcase in vivo how big.LITTLE processor configuration works (for a background on what big.LITTLE works, check this out). The processor, we reported earlier, reached a whopping 24,249 on Antutu according to one trusted source.
The tablet was running a series of applications to demonstrate how eight cores coexist with varying load. In some scenarios, like video playback or map navigation, only the four Cortex-A7 cores were used with the A15 in deep sleep state. Switching to web browsing used one Cortex-A15 and three Cortex-A7.
Swap that for complex graphics, all four Cortex-A15 would be fired up. Note that the product didn’t provide with any details about energy savings gained by using the (unknown) GPU rather than both sets of cores. As for the tablet itself, it was a prototype not unlike the mobile development platform Qualcomm displayed at its booth.
Presented in a rather eye-catching bright yellow chassis, it has a number of ports (including USB 3.0 and a microSIM) and has a big 10.1in display. Samsung is one of five SoC manufacturers, together with Renesas, Mediatek, Fujitsu and CSR, that have committed to implementing big.LITTLE on their products.
