Curious as to whether it works that way
It depends on whether your workload is similar to the benchmark, Colin My old system is an i7-960 that also does around 5,000. On my tests so far the new system is 4 to 10 times faster on time-consuming processes like calibration, registration, drizzle integration and linear normalization.

It's excellent news as you don't have "fear" a power outage and lose your swap cache.
Yes, I think that's right, Chris. The improvement from the RAM disk is fairly small. The comparison is with a NVMe SSD. If I was using a SATA SSD or, heaven forbid, a spinning disk then the difference would likely be significant.
