As you know at IBC 2018 the Amlogic team showed new three reference boards based on new Amlogic S905Y2, Amlogic S905X2, and Amlogic S922 processors. All new SoCs running new Android TV 9.0 P (Pie). The Amlogic S905X2 and S905Y2 are actually an updated version of Amlogic S905X. In the further part of the article, you will find a functional comparison S905X SoC with its upgraded versions of the S905X2 SoC and S905Y2 SoC.
As you also know, new TV Boxes with new SoCs has appeared on the market. We recently showed you a few TV Boxes with the new Amlogic S905X2. The S905X2 SoC is specially designed for TV Box, for example Above in the picture DV8519 Android TV P TV Box device from SDMC. The S905Y2 SoC is designed for OTT 4K HDMI dongles / HDMI Sticks. Below you will find a functional comparison of the new Amlogic S905X2 and S905Y2 with the “older version” Amlogic S905X SoC, which is still very popular and is present in most TV Boxes available on the market.

As we mentioned, S905Y2 SoC is dedicated to HDMI Dongle (but recently we showed you the A95X Plus TV Box with this SoC). It is difficult to find a large number of HDMI Sticks powered by S905Y2 on the market, so a good example is the great looking HDMI Android TV Dongle also from SDMC (the company is a provider of Google-certified devices based on Android TV 8 Oreo & Android TV 9 Pie) called SDMC DV6067Y 4K Android TV dongle.
