AMD A520 Chipset
Today, AMD completes its 500 Series Chipsets for its AMD Ryzen processors with the launch of the AMD A520 Chipset for socket AM4. The AMD A520 Chipset is the successor of AMD A320 Chipset which launched in early 2017. This is entry-level support for AMD 3rd Gen AMD Ryzen Desktop Processors (Ryzen 3000 series Zen 2 Architecture) on the AM4 socket platform. The new A520 Chipset also allows future support for future upgrades based on Zen 3 (Ryzen 4000 series) when they are launched. However, once again it does not support AMD Ryzen 5 3400G and Ryzen 3 3200G.
The A520 Chipset primary upgrade is the use of PCI-Express 3.0 (PCIe Gen 3) General Purpose Lanes instead of A320’s PCI-Express 2.0 lanes. This means a broader range of connectivity options and faster performance to those peripherals. For example, it can support 4x SuperSpeed USB (10Gbps) on 3rd Gen Ryzen processors. Up to 2 native USB 3.1 ports, 5 USB 3.2 Gen 2 Ports, 4X SATA ports, 6 native USB 2.0 ports, and 26x usable PCIe 3.0 lanes with a 3rd Gen Ryzen Processor.
Otherwise, it supports the same PCI-Express 3.0 lanes to graphics and SSD and CPU Chipset Uplink speed. There is no support for PCI-Express 4.0 graphics or SSD. There is no dual-graphics support. Also, importantly, there is no support for overclocking.
The AMD A520 Chipset is available now from major motherboard manufacturers worldwide.
AMD has listed some boards that will support this, the A520 motherboards you have are the ASRock A520M Pro4, ASUS TUF GAMING A520M-PLUS, Biostar A520MH, GIGABYTE A520 AORUS Elite, and MSI MAG A520M Vector WiFi. Some of these are micro-ATX form factor and the others are ATX form factor. This chipset would also be perfect for mini ITX, so we will have to see if boards of that stature come about.
