The most important parts here are Renoir and Van Gogh. Renoir is unreleased Zen2 based APU, and Van Gogh is Semi-Custom product ordered by someone, for sure - not AMD's own product, that you will be able to buy off the shelf.
It means very simple thing. Somebody is testing how well software works with AMD CPUs, of all sorts, for upcoming switch to Apple own, x86 Semi-Custom based chips, that are designed by AMD, and manufactured by TSMC.
