If you mainly use one or two apps at a time, a lower memory option may be sufficient. If you multitask, play games, edit photos or use several browser tabs and apps at once, more memory can help the tablet run more smoothly.
Some HONOR tablets support OS Turbo memory expansion, which uses part of the storage as virtual memory. This can help with multitasking, but it is not the same as physical RAM, so check the base memory specification too.
