As expected, AMD has finally announced its entry-level A520 motherboard lineup which has been introduced by its board partners. The AMD A520 motherboards give entry-level Ryzen PC builders more options to select from in the budget range while offering a list of new features over the older A320 and B450 motherboards.

The AMD A520 motherboards have a lot to offer aside from their entry-level (sub $100 US) prices. The motherboards carry increased I/O, better quality components, and support for next-gen Ryzen CPUs & APUs in addition to the existing ones, something that we cannot expect from the aging and much older A320 boards.
