That is useful info, but still does not quite address the question.
The question was how memory type, memory amount and bandwidth factor into actual performance. So let me rephrase: Given a budget of $X, what performance/limitations should you expect with
- 256GB of non-unified DDR5 in a PC, just CPU
- 128GB of DDR5 for an APU
- 96GB of unified DDR5
- Whatever Nvidia will sell you for $X.
An answer of "just compare a single memory bandwidth number" seems a bit short. Sure, more bandwidth helps, but is half as much RAM at double bandwidth better or worse?
