Amlogic STB SoCs Comparison – AML8726-MX, S802, S805, and S812

The second quarter of 2014 is promising to be an exciting time for Android TV boxes based on Chinese SoCs with lots of announcements. Devices powered by Amlogic S802 quad core SoC such as M8 and Vega S89 are already available, Rockchip RK3288 Android TV boxes are likely to sell in May, together with AllWinner A80 development board and tablets, and Android media players probably coming to market in June or July. But Amlogic S802 is not the only new quad core processor announced by Amlogic, with S805 and S812 soon to be featured in HDMI TV sticks and TV boxes.

Amlogic IP/OTT STB SoC page has a comparison table for their four STB SoC. Let’s go through this table to see which processor may better match different end-users requirements.

First we’ll notice none of Amlogic SoCs feature SATA nor USB 3.0, so for those of you who require fast local storage transfer, you may be out of luck. All of the new S80x SoCs come with Mali-450 GPUs so 3D graphics performance will be very good.  Component video output support has been dropped from the new SoCs, probably because few people are still using YPbPr, with the vast majority of TV now supporting HDMI. H.264 1080p encoding is now supported, which , at least in theory, means you can do FHD video conferencing, something which was not possible with AML8726-MX (720p max). S812 and S805 are the only two SoCs in the table capable of supporting H.265/HEVC videos in respectively 4K and 1080p resolution, as well as Gigabit Ethernet. As fast I know MX only supports Android 4.2, but the latest S80x SoCs all support Android 4.4 Kitkat.

So let’s summarize the advantages, and potential use cases, of the different Amlogic’s platforms:

  • AML8726-MX – Good for 1080p video playback, and light Android usage. Proven design, cost effective (Full box with remote ~$70). Some hardware platforms support DVB-T(2), DVB-C, or DVB-S(2).
  • S802 – Good for 1080p and 4K video playback. Excellent performance with a quad core processor, Octa core GPU. Could be also used as a pretty good gaming platform.  No HEVC support.
  • S812 – Same as S802 but adding H.265/HEVC video decoding up to 4K and Gigabit Ethernet. This makes it more future proof than S802, and it could potentially be used as a media center with a USB hard drive and Gigabit Ethernet connection.
  • S805 – Upgrade for AML8726-MX with faster multi-core performance, better GPU, HEVC, 1080p H.264 video encoding, and Gigabit Ethernet. Apart from 4K support, it can do anything S812 does, so if you don’t need 4K video playback and output, this could be a cheaper solution. Power consumption should also be lower than to the Cortex A5 cores instead of Cortex A9 for the other SoCs.

Thanks! Hope that Xiaomi will start to sell their tv box soon, which is quite cheap and has some features.

very interesting lineup from Amlogic, but with some weird choices at time, the HEVC must be standard now with all SoC, and I dont’ like the A5, an A7 at least would be much better, but for a set up box, it think it would work without much problem

now I’m looking for a DVB S2 box, with h.265 support, so the S812 or S805 would be perfect, but if some manifacturers decides to do it with the RK3288, then, all the amlogic lineup will be so dule and not interesting

Didn’t know about the S812, good news at least it has HEVC but should really have a HDMI 2.0 video output as well for future proofing, hopefully it’s something that can be added to it.

The S805 looks a much better budget option than the now getting on in age 8726-MX series.

@Dan

sure, but the HDMI 2.0 wouldn’t be much a problem in the near future, but I think the real problem it’s the aging cortex A9 and much more cortex A5, with the RK3288 and A80 this time ready to take upon set up box, it’s really hard to go with amlogic unless they have a very good price

the S805 will be at 40$, very nice price for a HEVC player, otherwise, the video from charbax shows a lot of designs based on amlogic SoC

@natsu Let’s not forget that the A9 is at its latest revision which should make it a bit better. That and the 2 GHz frequency should be good enough for a decent set top box. Sure if you’re into specs and benchmarks you’ll want something better but for most consumers a quad 2 GHz TV box does the job quite well I think. What is missing here and what you will notice is some high speed connection to an external drive like SATA or USB 3.0 but I guess you can always use the gigabit Ethernet connection to a good… Read more »

Any rumors on when first S812 boxes are planned for arrival? I’m itching to get my first XBMC TV box with S802 being the primary candidate now but I’m also thinking that probably it’s wiser to wait for S812.

Small correction here. Amlogic 4.4.2 sources officially support MX/MXS/MXL too. In SDK tree there are configurations for reference boards g18 (MBX), g33 and g34 (MID). Noone from manufacturers seems to care about it. I can confirm that KK runs pretty nice on MX2 (G-Box Midnight MX2) and Zoomtak M6 devices. And… KitKat does not support Flash Player and I believe it won’t be supported 🙂

Hi there, Now I’m looking for S805 since we are not object to 4K content, but need DRAM 2GB with FLASH 8G. Do you think it’s too much for this recent STB?

hello I would like to know from you I bought a player with procesore S802 but looking around at some publicita put decoding H265 maybe I was wrong to inform me well .you can tell me if the law H265 .maybe with adroid app you can read I’ve read in the My s3 with mxplayer

Hi. Does s802-h chipset support DTS and DD+ downmix to 2 channel stereo or only pass-through?

Well. When you test video playback with XBMC it does not make any difference, because xbmc support software transcoding of DTS and AC3. You should really test playback with in-built video player, right? What is the advantages of having dts hardware decoding? What does special av support means from the table above?

I got tronsmart mxIIIplus, and on specs it says that it supports hevc up to720p. But i tested it and it supports hevc ip to 4k in mx player (kodi goes up to 1080). So why confusing people with that? Second question, is there any difference between s812 and s812-h chipset? Do those two exist, or is thos “h” just a marketing trick? What does zhat “h” stand for, and what does this “plus” in some boxes stands up for? Please, explain if you can, i am curious about that. And,third, is now a good time to get a s812… Read more »

hello,can anyone please tell me if s812 will be OK even though i have not got a HD TV, will a s812 TV box still play alright. i do have 2 HDMI ports and use a Xbox and view sky with no problems, sorry if i sound daft but im not at all sure if it will work. also does any one know what channel a TV android box will play on, will it be one of the HDMI channels, hope someone can help, thanks Gaz.

Gaz, I use an older tv with an mxq w/s805 which as an xbmc player is efficient. I use the av out to my tv av in though I can use scart converter input from av since the tv does not have hdmi. The mxq has good hdmi out to a tv so best of both worlds. If needed you could invest in a three way hdmi switched which would also work with the 812 box and your other hdmi out gadgets. If your android does not have av out I would suggest the switcher for your hdmi in to… Read more »
