I have my 2012 Mac mini i7-quad core @ 2.3Ghz @1T SSD right here too. The new 
2018-2019 mini runs rings around it too … The old one tested the same way takes 
about 7.5 seconds per raw file conversion and output compared to the new one at 
just about 2 seconds, averaged. And the editing experience is much slower, 
about 3-5 seconds per new file selected, when compared against the new one as 
well. 

The memory use numbers for LR on the old system is very very similar to the 
memory use numbers for the new system, never actually exceeding 7G RAM. 

This doesn't give me any info at all, however, trying to compare the 
performance of my current Lightroom on Mac mini performance with Toine and 
Henk's Lightroom on PC computers with respect to memory use and rendering 
performance. That's what I was looking to understand. 

Lightroom does seem to recognize the i7-six core onboard GPU (Intel UHD 
Graphics 630, Metal-compatible) and allows me to turn on performance 
enhancement, but it is a little shy on GPU RAM at 1.5G rather than the 2.0G 
minimum on the Adobe web page that's recommended. I see a small boost in the 
frame-to-frame performance with the GPU performance enhancement turned on when 
I'm scrolling or doing a rendering adjustment, but it moves by so fast that 
watching the numbers in Activity Monitor doesn't show anything and I don't have 
the performance analyzer software I used to have (which would capture a trace 
on a much higher sampling rate basis) installed any more.
