The 3770K Rig had 16GB (2 sticks) of DDR3 2300 RAM CAS 16 or 18 timings (I forget exactly, but I bought it in 2012 so it's old)
The 1800X Rig had 16GB (2 sticks) of DDR4 3000 RAM and CAS 14 1T
The thing that really surprised me was 400 Mhz on a 6 year old CPU was significantly faster than any IPC gains made over that same time period, based on my tests, for processes that weren't as multi threaded. My test wasn't perfect but it was a very fair and controlled "real world" test, using the same images and everything, doing exactly what I use it for. Anything heavily multi-threaded though and the Ryzen destroyed it, but that was in line with expectations.
I REALLY want to buy Ryzen haha but this test kind of took the wind out of my sails given that it is basically what I would be buying a new computer to help speed up. Some processes are faster but some are slower. Overall it's probably a bit faster or equal once you average both processes (HDR Merge & HDR Create). Exporting is of course massively faster, as expected.
This is my graph (A NEF is a Nikon RAW image file, in this case 36 megapixels each):
