These two processors are the same model, both HI 3798 MV 311/310, but whether they can be brushed depends on the actual situation. If the processor, WiFi chip, RAM and ROM are all the same, it may be brushed. If it's different, it's best not to brush it.
You can see what processors you download, what WiFi you support, and whether ROM is EMMC or NAND. You can brush it if it meets the requirements.
