- CPU speed is important in pretty much all steps
- Multiple CPUs can help, but not as multiple GPUs. I would simply spend money on a better single CPU system with 2x GPUs rather than the money for a dual CPU system.
- RAM is important depending on the amount of photos. The minimum requirements for zephyr are 16GB, lets say that if you always work with less than 1000 photos, 32GB are more than enough.
- the GPU is very important, especially the cuda cores. Note that generally it's much better to get 2x mid/high tier cards rather than the highest tier card possible. GPU memory is mostly important for the photoconsistency step, but its automatically handled if there is not enough ram. We suggest at least 2GB.
Make also sure to get a good NVMe SSD
