Amlogic S905X5 Armv9 TV Box SoC supports AV1, H.266, Ai-SR

The Amlogic S905X5 may be first the Armv9 processor designed for set-top boxes (STB) and TV boxes, supports the latest AV1 and H.266 video codecs, and also comes with a 4 TOPS AI accelerator.

We don’t have the full details yet, and the news comes from a tease from SEI Robotics which is about to unveil an Amlogic S905X5 AI-SR (AI Super Resolution) Android TV box at IBC 2023.

Amlogic S905X5 TV Box

Preliminary specifications for S905X5 SoC and SEI Robotics TV box:

  • SoC – Amlogic S905X5
    • CPU – Quad-core Armv9 CPU (likely Cortex-A510 cores) delivering 40K+ DMIPS
    • GPU – Arm Mali-G310 V5 entry-level GPU clocked at 1 GHz for 4K HDR user interfaces
    • VPU – Up to 2x 4Kp60 10-bit H.266/VCC and AV1 video codecs, and the usual VP9, AVS3, H.265/HEVC, H.264
    • AI accelerator – 4 TOPS NPU enabling AI-SR
    • Process – “Second generation” 6 nm process
  • System Memory & Storage – TBD
  • Video Output – HDMI 2.1 up to 4Kp60 with eARC (enhanced audio return channel), VRR (Variable Refresh Rate), QMS (Quick Media Switching)
  • Audio – Support for Dolby, Dolby Atmos
  • Networking – Ethernet port, likely WiFi and Bluetooth
  • USB – 2x USB Type-A ports, 1x USB Type-C port

AI-SR (AI super-resolution) is just an upscaling method that leverages artificial intelligence to deliver a better image quality. For example, you can stream a 1080p60 video stream on a 4K TV close to the quality of a 4K video streaming providing the AI-SR upscaling works as expected.

It’s nice to see one of the first entry-level Armv9 processors soon come to market and it boasts some relatively uncommon features such as H.266 and Ai-SR. SEI Robotics did not say when the new Amlogic S905X5 “Ai-SR” Android TV box will come to market but I suspect that will be a 2024 story.
