It's not a new topic when talks about Amlogic S905X2, S905Y2, S922 processor since Amlogic had already showcased them at IBC 2018.You may
have read many articles about them from different bloggers. Today I just want to introduce our available products based on them while talking
about the difference between them.

Amlogic S905X 1gb solution substantially lowers the production cost to enable increased market penetration of 4K set-top boxes
worldwide, which makes it becoming the most successful CPU in the OTT TV box market. Amlogic S905X2 / S905Y2 are actually
an updated version of Amlogic S905X. Compare with Amlogic S905X, Amlogic S905X2 and S905Y2 upgrade their GPU to the
Mali-G31 MP2 model with new features such as support for ultra-low power, Dolby Vision, H.265, HDMI 2.1, USB3.0 etc.
There was no big difference between S905Y2 and S905X2 in function.The S905X2 is specially designed for TV Box, for example
 DV8519 Android TV P device 

The SoC S905Y2 is designed for OTT Dongle because of its small package size. The application product is
DV6067Y 4K Android TV dongle,you can find more info at the product page

Amlogic S922X VS Amlogic S912

Amlogic S922X is an heir of Amlogic S912 which has a Hexa Core configuration with four Cortex A73 cores and
two Cortex A53 low power consumption, It support for USB Type-C/PCI-E U which actually has at least 10 times
faster in speed compared traditional USB 2.0. Amlogic S922X has a next-generation ARM Mali-G52 MP4 GPU with
support for all HDR standards.  We also launched an Android TV Box running on Amlogic S922X, you can find
