A New Challenger Appears: Realtek Dragon NIC on ECS Z170 Motherboards
 

When a motherboard manufacturer develops a product, it has to consider which third party controllers are going to be used. When we discuss network controllers, there are several entrants in the market that satisfy a range of prices and marketing opportunities although I perhaps would not call the motherboard network controller market competitive or crowded. When an engineer/sales rep has to choose the controller, depending on the NIC manufacturer there may also be firmware and software additions which add value.
