S912 VS S812, What’s different?

s812 VS s912

Nowadays, a wide variety of Android tv boxes flooded the network streaming media player market, variable quality of the situation of weeding. Such as Amlogic S905, S812, S905, S905X, and S912, RK3229, RK3399, RK3388, etc. Even some wily old bird could be confused, it is completely new to the novices. Now Amlogic s912 vs S812, to further distinguish between the characteristics of them.

Big Surprise at the end of the post!


Amlogic S912 is an advanced application processor designed for high-performance 4K OTT/IP set-top box. The main system CPU is an Octa Core ARM Cortex A53 CPU and with ARM Mali-T820MP3 GPU, a secured 4K video codec engine and best-in-class HDR image processing pipeline.

But surely Amlogic S912 with eight Cortex A53 cores and its “multi-core high-performance 3D GPU”, namely ARM Mali-T820MP3 must deliver a significant boost in performance.

The Amlogic S812 chipset is comprised of an ARM cortex-A9 quad-core 32 bits processor, clocked at a maximum speed of 2 GHz and a Mali 450 graphics octa-core coprocessor.

Amlogic S812 is an advanced application processor designed for Set Top Box. It integrates a powerful CPU/GPU subsystem, and a secured 4K video CODEC engine with all major peripherals to form the ultimate low power multimedia AP. The main system CPU is a quad-core ARM Cortex-A9r4 CPU with the eight core ARM Mali-450 GPU.

What’s different between Cortex A53 and Cortex-A9

As well known Cortex-A9 is Armv7-A, regarding Cortex-A53, it is ARMv8-A (i.e. 64bit architecture). The instruction set is not compatible with Armv7-A although the philosophy has inherited Armv7-A. Therefore, it is definitely different from Cortex-A9. However, AArch32 mode of Cortex-A53 can emulate the Armv7-A (i.e. Cortex-A9/7).

Play different in 4K and 3D  function

The newer design on the Amlogic 912 includes 4K H.265 hardware video decoding and 60hz 2160p video streams. This means that the Amlogic S912 chipset wins if you are considering it mainly for media streaming and playing purposes.

The octa-core Mali 450 graphics processor included in the Amlogic S812 chipset, on the other hand, is about 30% faster and thus more capable than the humbler Penta-core included in the newer S912 chipset. This means that as a 3D graphics gaming tv-box, the S812 would be the winner.

Learning about these product parameters is an important skill for recognizing good streaming media players. So now have you known how to choose a better tv box, picking a right gift for your Dad, family or friends for a coming Christmas?
