In most cases the maximum project size that can be processed is limited by the amount of RAM available. Therefore it is important to select the platform allowing to install required amount of RAM.
See Memory Requirements.
Complex geometry reconstruction algorithms need a lot of computational resources for processing. A high speed multi core CPU (3GHz+) is recommended.
Agisoft PhotoScan supports GPU acceleration for image matching and dense cloud generation steps, so high-end OpenCL or CUDA-compatible graphics card can speed up the processing.
