Hello,
I would not recommend i9-13900 and i9-14900 series, as many Metashape users have problems with them, see the discussion thread here:
https://www.agisoft.com/forum/index.php?topic=15903.msg70034#msg70034Some managed to resolve the issues, by tweaking the hardware settings, but personally I wouldn't recommend to get them, in order to avoid all the hassle.
So for Intel CPUs, i9-14700 could be an option, and for AMD some fast Threadripper would be also good, but I think it is not required to get more than 48-64 physical cores.
