What went wrong with RDNA 3...?

Much has been made about the performance, or lack thereof, in the RDNA 3 architecture. Before launch, rumours persisted of 3+ GHz core clocks, and I had tried to make sense of them at the time - to no avail, leading to predictions that were around 2x the performance of the RX 6900 XT. 

Additionally, people (aka leakers) were really misunderstanding the doubling of FP32 units in each workgroup processor and so were counting more than actually existed in terms of real throughput performance and, I think it's safe to say that this decision from AMD was a disaster from a consumer standpoint. 

But is that really the reason RDNA 3 has been less performant than expected? Let's take a look!
