How Much Bandwidth Do Streaming Services Use?
However, for streaming, you only require a certain amount of speed. For Netflix HD streaming, Netflix says it will take 5.0 Mbps (Megabits per second). Other services — from YouTube to HBO Go — should require a similar amount of bandwidth for their HD, 1080p streams. if you’re using Netflix’s 4K UHD stream — and you’re probably not — that will require 25 Mbps. Music streams will require much less bandwidth than video streams.
Take this into account. If you’re using a Netflix HD stream, upgrading from 25 Mbps to 50 Mbps won’t help you. But upgrading from 5 Mbps to 15 Mbps would definitely give you some wiggle room, allowing you to handle multiple streams or a stream and some downloads without problems.
