I recently got a Netgear R6220 router, an AC1200 dual-band router with very impressive specs. It was awarded the best router in 2016 and now in 2019, I still think it is a very good router. It has a 2 core Mediatek MT7621 (MIPS) processor with 128 MB RAM & 128 MB ROM i.e. ample space with some good processing power. Below you can see the impressive specs. BTW: I got this for almost 15 USD which was a steal!
