Samsung’s upcoming Exynos 5433 gets benchmarked

Samsung’s next Galaxy Note will debut early next month during the company’s ‘Unpacked Episode 2’. The South Korean giant is also set to unveil the Exynos 5433 Octa SoC which will power the Galaxy Note 4 which will be the first SoC based on ARM’s ARMv8-A architecture to ship with an Android device.

The Exynos 5433 Octa will pack two core islands but will swap the usual Cortex-A15/A7 combo for a fresh pair of Cortex-A57/A53 cores at unspecified frequencies along with ARM’s big.LITTLE technology. Current benchmarks scores however suggest that Samsung’s new silicon outshines Qualcomm’s Snapdragon 805 SoC by over 2500 points on AnTuTu while running on Android 4.4 KitKat, i.e with the Dalvik VM instead the 64-bit optimized ART. – The Exynos 5433’s Cortex-A57 cores clocked at 1.3GHz beat the S805 which employs four Krait 450 at 2.5GHz!


Of course, the downside of bumping the instruction set to have such a high IPC also means that the chip will draw more power, AnTuTu reports that the Exynos 5433 managed to break the 4W ceiling at 2560×1440, a record otherwise only attained by Nvidia’s Tegra K1 at 1920×1080. That being said, benchmarks don’t necessarily translate into real life performance so we’ll have to review actual Note 4 units before making any sort of conclusions.


The new 64-bit Exynos silicon will be manufactured on a 20nm node with Samsung’s HKMG process, Samsung will also opt for ARM’s latest Midgard high-end offering; the Mali-T760MP (exact number of cores unknown) which is currently the most architecturally advanced mobile GPU. This also means that Galaxy Note 4 will be able to have more breathing space as far as pixel drawing and processing is concerned, thus further curbing (if not eliminating) the performance drawbacks of having a QHD display.


We hope that Samsung will draw a fine line between the performance-efficiency factor by making proper adjustments with regards to power saving/thermal management mechanisms such as thermal throttling, clock gating or dynamic frequency scaling.
