64gb is pure RAM? I thought Apple Silicon was efficient at paging SSD as memory storage - how important is RAM if you've got a fast SSD?

Memory speed is the most important factor with LLMs and SSD is very slow when compared to RAM.

While Apple Silicon's memory compression and SSD swapping are efficient, RAM access is still ~100x faster than SSD, so sufficient physical RAM remains crucial for memory-intensive workloads like running large LLMs.
