AMD and its motherboard manufacturers have announced A520 motherboards for the budget market segment. They supersede the existing A320 motherboards that were released more than two years ago. Almost all of these motherboards are expected to be priced under $100, making them suitable for budget builders. They are generally used in offices and other non-enthusiast workplaces. With the AM4 B550 motherboards costing significantly more than their B450 counterparts, these A520 motherboards may be a lucrative offering for mainstream buyers as well.

AMD A520 Chipset Specifications vs. A320, B550, X570

AMD’s A520 chipset can be thought of as an upgrade of the A320 chipset. Most of its specifications are the same as the older AM4 budget chipset. It still supports PCIe 3.0 for graphics and CPU storage, like the A320 chipset. In comparison, AMD’s mainstream B550 and X570 motherboards support PCIe 4.0 for the GPU and CPU storage. PCIe 3.0 is acceptable for the budget A520 chipset as most people building entry-level systems will not be using an expensive PCIe 4.0 storage device. Also, mainstream GPUs like the 5600/5700 class from AMD and the 2060/2070 class from Nvidia (including the next Gen ones from AMD and Nvidia) will not be bottlenecked by an x16 PCIe 3.0 slot.

AMD A520 AM4 Specifications

The only significant difference from the A320 chipset is that the A520 chipset upgrades the general-purpose lanes from PCIe 2.0 to PCIe 3.0. AMD’s older A320 chipset had four PCIe 2.0 lanes. It does not support dual GPUs or overclocking like the A320 chipset. The B550 chipset has four additional PCIe 3.0 lanes when compared to the A520 chipset. X570 only uses PCIe 4.0 lanes and has no PCIe 3.0 lanes.

AMD A520 chipset for AM4 motherboards supports the following

  • 1x SuperSpeed USB 10Gbps (USB 3.2 Gen 2) port
  • 2x SuperSpeed USB 5Gbps (USB 3.2 Gen 1) port
  • 6x USB 480Mbps (USB 2.0) ports
  • 2x SATA 6Gbps ports for storage media
  • 4x PCIe 3.0 lanes for add-in cards
  • 2x PCIe 3.0 lanes that can be configured for add-in cards or used to add two additional SATA 6Gbps ports

CPUs Supported by A520 motherboards

Asus A520 Motherboard CPU Support

The A520 motherboards will support Zen 2 based Matisse CPUs and Renoir APUs (4000G Series). They will not support older 1st or 2nd Gen Ryzen CPUs or Ryzen 3200G/3400G APUs. Most motherboard manufacturers have hinted that the A520 chipset will support future CPUs. However, Asus has gone one step further and accidentally listed that the future Cezanne and Vermeer processor families will work with AM4.
