OnePlus 9's design is newer than the OnePlus 7's, although it is just a bit thicker and a bit heavier. The OnePlus 9's processing unit is very similar to the processing unit in OnePlus 7, and although the OnePlus 9 has a greater amount of RAM, they both have 8 processing cores.
OnePlus 9 counts with a display that's very similar to the screen in OnePlus 7, although the OnePlus 9 also has a quite better resolution of 1080 x 2400, a little larger display and a little bit more pixels per inch in the screen. OnePlus 9's memory to store more games and applications is very similar to OnePlus 7's one, both have equal internal storage.
OnePlus 9 features a little bit better camera than OnePlus 7, because although it has a tinier diafragm aperture, and they both have the same resolution back camera, the OnePlus 9 also counts with a way better video quality and a much bigger camera sensor shooting much higher quality photos and videos.
OnePlus 9 features longer battery lifetime than OnePlus 7, because it has a 4500mAh battery size.
Although OnePlus 9 is a better device, it costs a lot more money than OnePlus 7, and it doesn't have such a good price and quality relation as OnePlus 7. So if you want that extra features and specs, you can buy OnePlus 9, but if you don't you can save a couple dollars and buy the OnePlus 7, letting go some features and specifications.
