Amlogic S805X2 AV1 capable processor was first teased as an update to S805X and S805Y Full HD TV box processors in 2019 with very little details. But companies have started to list some S805X2 based Android dongles and TV boxes.
That means we also have additional details for the processor, and we’ll look into SDMC DV9035 TV box and SEI Robotics SEI103 dongle, neither of which should be sold to end-users, but instead OEM’s or content providers.

I suppose there’s WiFi as well since that one does not seem to come with Ethernet. SEI103 is a Google certified Android TV OTT stick/dongle, but the company says it’s running Android TV 10 or higher. Netflix and Amazon Prime VIdeo are both pre-certified as well.
There’s no pricing either since it’s for operators, but you can be able to find more information on the product page. As a side note, last time I wrote about SEI Robotics, it was about their S905X4 developer kit, and one person who purchased it after reading the news on CNX Software only received it after six months, and it arrived with a broken capacitor and without access to a software development kit.
Amlogic S805X2 vs S805X and S805Y
SMDC also provided a (partial) comparison between Amlogic S805X2, S805X, and S805Y.
SoC | S805X2 | S805X | S805Y |
---|---|---|---|
Process | 12nm | 28nm |
|
CPU | Quad-core Cortex-A35 up to 15K DMIPS | Quad-core Cortex-A53 up to 11K DMIPS | Quad-core Cortex-A53 up to 13K DMIPS |
GPU | Arm Mali-G31 MP2 | Arm Mali-450 MP3 |
|
Memory | 32-bit DDR3/3L/4, LPDDR2/3 up to 4GB DDR2666 | 16-bit DDR3/4, LPDDR2/3, up to 3GB DDR240 | 16-/-32-bit DDR3/4, LPDDR2/3, up to 3GB DDR240 |
Video Decoder | 1080p60 10-bit AV1, H.265, VP9 P-2, H.264, AVS2, MPEG4/2/1 | 1080p60 10-bit H.265, VP9 P-2, H.264, AVS2, MPEG4/2/1 |
|
HDR | HDR10/10+, HLG | HDR10, HLG |
On the video side of things, the most important new features and AV1 and (optional?) HDR10+ support, and the processor should even be faster with 15K DMIPS, the more modern GPU should enable support for OpenGL ES 3.x/Vulkan 1.x, and the system supports up to 4GB RAM, although that’s unlikely on the ultra-low TV box targeted by S805X2 processor.
SDMC further explains Amlogic S805X2 consumes 35% less and is 25% more efficient thanks to the Cortex-A35 core and 12nm process which allows Amlogic to increase the frequency. At the same frequency, a Cortex-A53 should be faster than a Cortex-A35, but Amlogic S805X2 must be clocked at up to 2.1 GHz considering 1.78 DMIPS/MHz, while S805X runs at 1.2 GHz and S805Y at 1.4 GHz.
