References to Navi 10, 12, 14, and 21 have appeared in lines of Linux driver code. AMD has already revealed the Navi 10-based RX 5700 XT and RX 5700, and it seems that there will be quite a few more GPUs to be released down the road. The same code also makes mention of "Lite" variants of the graphics processing units.

Hmmm and Apple has registered new portable computer references for the next months. I will wait for my IOS developer machine refresh for now.
