Following of new round of benchmarks from MacRumors, my take outs are: 16 GB is (much) better than 8 GB from a speed point of view (well, duh!), the Mac mini is the best most of the time with a few exception (slower than MBP on SSD write speed is one such exemple, hard to explain). Adobe Lightroom Classic doesn’t take advantage of the RAM difference, which is not surprising to me (thanks to multiplatforms Adobe’s software) You can get all the details from MacRumors website: here and here.
