Matthew,
You can check out the build details on the PI benchmark site - just expand the category and click on the serial number:

Something that is pretty obvious is number of threads has a huge impact on CPU score. Swap score is largely influenced by presence of RAM drive or in my case RAM Cache. The highest swap score across any CPU is around 20,000 and this seems to be achievable regardless of the CPU chosen.
I went through the benchmarks and picked out the highest CPU score and plotted that against threads. The dip at 20 threads is an Intel i9 whereas the points either side are AMD Ryzen processors.
