AMD engineer submitted driver code shares six new Device IDs. Vega20 was originally thought to move the architecture from 14nm to 12nm but it could well jump straight to 7nm. Supporting this idea, a next-gen Vega accelerator, as AMD officially stated at CES 2018, is being built specifically for machine learning applications on the 7nm node.

The Linux driver code that came to light this weekend contains references to six new Vega20 GPUs. In the screen shot below you can see the device IDs listed under the /* Vega 20 */ section. You can see that the code has been reviewed and signed off by three AMD engineers.
