A new Amlogic roadmap has appeared on the networks where we see the new SoC S905X4, S805X2 and S908X with hardware decoding 4K@120fps of the open source video codec AV1 that until now only had high-end Realtek RTD1319 SoC / RTD1311 and that we have not seen in the market yet. These Chips that are expected to compete with the latest SoC’s announced by Rockchip and that we hope not to see in the market until mid-2020 at least.
Amlogic S908X
This is the most powerful SoC of those announced is the S908X, predictably equipped with the latest CPU + GPU cores, support for 8K@60fps resolutions and 64-bit RAM. In addition to native decoding of AV1 codecs that improves the efficiency of HVEC and VP9 codecs by 25 to 40% and also support for AVS 3.0 that will be extended in the Chinese market.
Amlogic S905X4
The S905X4 is a new chip that is the evolution of the Amlogic S905X3 with which it is compatible pin by pin, which will facilitate its adoption by manufacturers. This new SoC seems to maintain the basic structure of the S905X3 with 4 ARM Cortex-A55 processors and an Arm Mali-G31MP2 GPU although with improvements in video playback with AV1 decoding and audio with the inclusion of two DSPs, they also have audio support AFE audio front-end and also WWE wake word engine, which indicates that it can be targeted to voice assistants, perhaps for future Amazon Alexa / Fire devices or for voice controls of upcoming Xiaomi Mi Box models.
Amlogic S805X2
This SoC is a new low range of which we have less information for boxes or other devices with FullHD video output at 60fps that we do not know its CPU + GPU configuration. This new S805X2 seems to also incorporate native decoding for the AV1 codec.
