Yes. I would assume that. I can't think of any routers made in the last 5 years, possible not in the last 10, that couldn't handle at LEAST 100Mbps up and down.
You don't really start seeing issues until you start shuffling over about 150-200Mbps WAN-LAN or LAN-WAN, especially depending on the protocol. Most modern ones with a gigabit WAN port should handle up through 200Mbps just fine, no matter the protocol. After that, it gets very dependent on the router hardware and the protocol in use (a lot of routers struggel with PPPoE. Atheros/Qualcomm chipsets seem to have very good PPPoE hardware offload so it doesn't really seem to slow them down, others struggle to hit 200-250Mbps when they can hit 700-900Mbps WAN DHCP).
