I can relate
Two months ago, I've upgraded from a Q8400 Penryn and 8GB RAM (2008 vintage) to a Dell Precision notebook, which runs an 6820HQ Skylake with 16GB RAM.
The Passmark scores are (from the website):
Q8400: 3227 (100%)
6820HQ: 8619 (267%)
I don't know why my scores are better than the ones on the site. Maybe I have better mainboards with faster interconnects, or better cooling which makes the CPU's throttle less. (I can run my desktop and both of the old and new laptops at full speed indefinitely without throttling, which is often not the case for prebuilt system, especially laptops.)
However, my real scores (running Passmark myself) are:
Q8400: 3561 (100%)
6820HQ 9125 (256%)
Even on the old computer, Calibre was fast enough in general usage, with a library of close to 900 books, with many Delphi Classics in there. The one thing where I do see a very noticable difference in speed is with said Delphi Classics. They convert a lot faster. Also, on the old desktop I could only run three conversions at once (4 CPU's minus 1, so I can still do other stuff), while the new laptop can run 6 conversions ((4 CPU's - 1) * 2 for hyperthreading). Yes, Hyperthreading does gain me the possibility to run twice as many conversions, while also doing them at least 2,5x faster
The 6GB of RAM also helps.
HarryT: Have you looked into the Calibre settings? It has a setting to set the number of processes. I often see the worker processes rise way over 12GB of RAM when converting multiple Delphi's at once.
