Amlogic S805X Processor is Designed for Low Cost TV Boxes with 1080p H.264, H.265 and VP9 Video Support

The low end of the TV box market is now highly competitive with Rockchip and Amlogic battling to offer the cheapest solutions available, as we’ve seen in a recent factory price list of TV boxes with RK3229 based devices selling for as low as $17.8, and Amlogic S905W based boxes going for $17.5 and up (per unit) for orders of 200 pieces. Amlogic has been working on an even lower cost SoC with Amlogic S805X based on four Cortex A53 cores, the same Mali-450MP GPU, but no 4K support, and instead H.264, H.265 and VP9 video decoding up to 1080p60, as I found out in a document shared on Amlogic Open Linux website.

Amlogic S805X will be quite similar to Amlogic S905X and S905D with the same CPU by clocked at a lower 1.2 GHz frequency, the same penta-core GPU, TrustZone support, and Fast Ethernet. The main difference is that in order to lower costs, they limited the multimedia capabilities to 1080p video decoding, and 1080p video output. Those last two actually make it more similar to Amlogic S805 SoC, but instead of a four Cortex A5 32-bit cores, S805X comes with more powerful Cortex A53 64-bit cores, and VP9 support was added to S805X.

The processor is likely be used in both Android and Linux TV boxes, as the company’s Mbox P241 reference platform / development board based on S805X SoC, comes with either 512MB DDR3 or 1GB DDR4, coupled with eMMC flash, and an AP6255 wireless module supporting 802.11 b/g/n/ac and Bluetooth 4.2.

I’ve yet to see any S805X TV boxes, even on Alibaba, but I’d expect them to sell retail for around $20 including shipping. The processor could also be an interesting choice for low cost development boards, competing against Allwinner H5 solutions.

  1. Wrt ‘competing’ against H5 on different devices than TV boxes it would be interesting how limited the count of USB2 ports is and whether S805X supports ARMv8 AES crypto extensions or not (H5 does, S905X does, S905 for example does not). Not to mention H5’s Gigabit Ethernet capability.

    Besides that some folks already test with H6 (nothing useful heard yet, am especially interested in performance of the single PCIe 2.x lane) so I would assume the area where such limited dev boards based on H5 or this S805X could survive is ‘below 15 bucks’ country?

  2. It would be nice if Amlogic stopped trying to confuse their customers by putting random stuff in chips constantly carrying the same name except for a trailing letter. They probably don’t realize that a number of potential customers will skip this one just because they’ve been told that “S805 is years old and 32-bit only”.
