The S905D3/S905X3/S905Y3 are very similar to each other and are from the SM1 Amlogic SoC family.

Here are the differences between them:

  • S905D3: enhanced audio (from AXG), 1x USB 3.0 or 1x PCIe 2.0, built-in 1G MAC and 100M PHY, two video decoders (4Kx2K@60fps + 1080P@60fps), Neural Processor Unit, MIPI-DSI and CSI input
  • S905D3-NON: similar to S905D3 but without NPU
  • S905X3: similar to S905D3 but without the DSI output and CSI input
  • S905Y3: similar to S905X3 but without DVB interface and built-in Ethernet

There are also -h variant of S905D3/S905X3/S905Y3. it is a variant of the soc that has include Dolby/DTS licenses.
