A great question, I don't have answers but do have a few observations.
- I recently bought a new laptop with quad i7 @2.3 GHZ. It is perhaps
10% faster than my deskto Quad AMD APU at 2.9GHZ on doing a "Local
Contrast" exercise in the Digikam editor, which to me is the most CPU
intensive activity I notice.
- Both of these systems are very usable for Digikam, but more speed is
always better.
- Digikam seems to run (and max out, occiassionally) on one core. I
believe I have seen Guiles comment that multicore parallel processing is
being worked on. In any case, for a given CPU Power dissipation, the
fewer the cores the better, I believe. More zip per core, until
multicore is ready.
--If you decide to go with a high power CPU (>100W), which will for sure
provide better performance, but want to keep it quiet, I highly
recommend you invest in a water cooling system (Slug on CPU piped to
radiator/fan on the back of the case). I have been very pleased with one
I have on an older 125W CPU. They are in the range of $80-$100.
- From what I have seen, the Facial Recognition feature seems to be a
big resource user. If you plan to use it, that is probably the best
benchmark to focus on.
--An interesting question for the developers might be - Will facial
recognition in the future be able to uilize the GPU APIs and pixel
engines? If so, that might make a high performance (gaming) Graphics
sub-system worthwhile. Otherwise, I doubt graphics performance would
make a lot of difference for still image processing. All this might be
dependent on your OS - I run openSUSE Linux. The Nvidia APIs (and
drivers) seeem more advanced here in this area.
A great question, I look forward to inputs from others, particularly on
good ways to benchmark systems with Digikam in mind.
