S805X2 AV1 Android TV dongles and TV boxes are starting to show up

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.

SDMC DV9035 S805X2 TV box

SDMC DV9035

Specifications:

  • SoC – Amlogic S805X2 quad-core Arm Cortex-A35 processor with Mali-G31 MP2 GPU
  • System Memory – 1GB DDR4
  • Storage – 8GB eMMC flash
  • Video Output – HDMI up to 1080p60 with HDR support
  • Video Codecs – AV1, VP9, H.265, H.264
  • High-dynamic Range – HDR 10, HLG, HDR10+Optional
  • Connectivity
    • 10/100M Ethernet
    • Dual-band 2.4GHz/5GHz 802.11a/b/g/n/ac WiFI 5 with optional 2×2 MIMO,
    • Bluetooth 4.2 or higher
  • USB – 2x USB 2.0 ports
  • DRM – Playready, Widewine
  • Power Supply – 12V/1.0A via DC jack
  • Dimensions – 100 x 100 x 23mm

S805X2 TV boxThe TV box runs Android 11 on Android TV operating system, supports Google Play and Google TV services,  Chromecast, Google Assistant, as well as streaming applications such as Netflix, YouTube, Sling and Hulu, etc.. Operators can opt to run the standard or a custom operator-tier Android TV launcher.

Additional details may be found on the product page.

SEI Robotics SEI103 dongle

SEI103 S805X2 Android TV 11 dongleSEI Robotics device looks more like a Google Chromecast, and the company lists the following specifications:

  • SoC – Amlogic S805X2 quad-core Arm Cortex-A35 processor with Mali-G31 MP2 GPU
  • System Memory – 2GB DDR3
  • Storage – 8GB eMMC flash (16GB as option)
  • Video Output – HDMI up to 1080p60 with HDR support
  • Video Codecs – AV1, VP9, H.265, H.264, VC-1 etc…
  • High-dynamic Range – HDR 10, HLG, optional Dolby Vision
  • Connectivity – Bluetooth 5.0 or higher
  • DRM – PlayReady, Widewine L1, Verimatrix, Irdeto

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

S805X

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.

This confuses me even more about A53 vs A35, and I can’t find a conclusive answer as to which one is better in what areas.

Seems simple enough. The move from 28nm to 12nm allows an A35 to demolish an A53 with increased clock speed and power efficiency, despite having lower IPC.

Wikipedia lists 2.24 DMIPS/MHz for A53, 1.78 DMIPS/MHz for A35.

15K / 13K = ~1.15x performance
15K / 11K = ~1.36x performance
2.24 / 1.78 = ~1.26 (A35 must be clocked ~26% higher to have the same performance)
1.2 GHz * 1.26 * 1.36 = ~2.06 GHz
1.4 GHz * 1.26 * 1.15 = ~2.03 GHz

So the approximate clock speed would be around 2.05 GHz.

Think small, medium, and large. A53 is old now generationally and it’s replacement is the A55. Were the A35 is a different tier and newer core generation to take the spot of smallest core architecture, previously it was A53 as the medium sized core, and A73 as the large, and no “small” 64bit core from ARM when they previously had a “small” 32bit core with the old A7. Now it is A75/A76/A77 as Large cores, A55 as Medium core size, and A35 as Small core. The benefits of A35 is a smaller more compact core with better efficiency, that equates… Read more »

Everyone’s looking for the next A55, but I want to see the Cortex-X2 paired with a Cortex-A36.

technically, suscessor of cortex-a35 is Cortex-A34 of 2019, not A36
https://www.cnx-software.com/2019/08/02/arm-cortex-a34-64-bit-only-low-power-core/

Great naming sense from ARM team, i know.

next a55 maybe the rumored A65 or other“Helios” CPU core.

Neither the A35 or A32/A34 is compatible with DynamIQ as far as I can tell. So there would need to be an A36 (placeholder name) to fulfill my sick fantasy of four tiers of cores on a single SoC (e.g. A35, A55, A78, X1).

I’ve seen the Helios codename. Should be interesting.

Cortex-A35 can only be combined with A53, and A73 (or older). The later cores you mentioned (A55, A75+) use different instruction set version and a different interconnect (DynamIQ).

My guess is that at the typical 7nm to 10nm that you’d find a Cortex-A55 in, the absolute size of a single core is so small that there is little demand for something even smaller. What does happen on the low end is that you see a Cortex-A55 cluster with no private L2 caches but only the shared last-level cache, similar to what you would have in a Cortex-A35 cluster.

When you look how small SOC on raspberry pi 4 really is. Like real silicon not actual package. It is really cool! 128 pcs like this overclocked to 5GHz 🙂
and still small like common intel package

I don’t own a tv-box and I’ve never had one. Question – which ones of them let you go root without involving hacks, kingroots and similar royalty? How common are such devices? I refuse to buy anything that requires aristocratic intervention in order to get root, so I’m trying to figure out if such devices are common among tv-boxen.

All Amlogic TV boxes that I have had provided root either by default or as an option in the settings.
This does depend on the manufacturer though. These certified boxes that can play Netflix or Amazon are for sure locked down but a generic S905x4 box is likely to offer root. You need to ask for that specific model though.

The RK3266 popular in emulation handheld machines has the same CPU and GPU at 1.3GHz. For anyone wanting real world examples of A35 abilities.

I think you mean RK3326? And that Linux powered microwave uses the RK3308 which knocks out the GPU.

Yes, good you spotted it?. It should be RK3326. My bad typo?.
