AMD's board partners are planning to introduce the entry-level A520 chipset-based motherboards in the coming week. The A520 lineup will be targeted at entry-level AMD Ryzen desktop PC builders who want to maximize value in their new PC build.

The main audience for the AMD A520 platform is the budget and value consumer base who want to get the best value out of products. The AMD X570 and B550 platforms are far out of reach from a wider audience as you're going to pay extra for the PCIe Gen 4 advantage. Sure there's the used B450 motherboard market but there's rarely a good deal due to shortage of these motherboards as production has moved over to the new 500 series chipsets.
