for those who are interested: according to [0] the marketing name of
this SoC will be "A311D" - specs from the linked PDF:
- CPU: Quad Cortex-A73 + Dual Cortex-A53 (max frequency: TBD)
- GPU: ARM G52 MP4 (4ppc)
- Memory: DDR3/4 LPDDR3/4
- Video decoding: 4K H265&VP9&AVS2
- Video Encoding: 1080P H264 H265
- HDMI-Tx: 4K2K
- Ethernet: 10/100M/1000M
- AV output: CVBS
- IP License: Dolby, DTS

W400 is the reference board for this SoC, it comes with:
- EMMC
- WIFI AP6398S
- DDR 2GB

if I had to guess then I would say it's the successor of the GXL (or
GXM?) family

Martin
