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.
