Quite frankly, there is no surprises that it is running some sort of Renoir chip in there because of the monolith design. So instead of the usual Vega 8, they customised it with a cut down RDNA2 GPU since they have the power and die budget.
The Van Gogh that leakers have found in drivers, etc.? If so, is it really the Series S CPU or a different (even if similar) thing? Either way, does it end up available in PCs or is it just some kind of leaked Xbox devkit or something? And perhaps most frustratingly, do we ever get a definite answer to a single one of these questions? 🤣
