If you buy AMD it is possible that you can upgrade later without throwing all your system away, unlike Intel systems. I am saying that because AMD is about to jump to 7nm chip burning, and given AMD past history, it will be compatible with current AMD chipsets. For me, parameters such as chip price, thermal efficiency, power draw and upgrade paths are as important as chip raw performance. In general, with Photoscan with more cores/threads you will never go wrong.
