iPhone 7 vs iPhone XS vs iPhone 12 pro

Currently using Gaia gps to create and navigate adventure motorcycle routes using a iPhone 7. I create them using the snap to road feature and quit often it doesn’t snap to the road. Just being curious if buying a newer iPhone with more Ram memory and faster processor speed would help this situation? Would I even be able to tell or notice a difference (worth the cost of upgrading) ? iPhone 7 2 mb RAM / IPHONE XS 4 mb RAM / IPHONE 12 Pro 6 mb RAM
