The major improvement in A520 over the older A320 chipset is that general purpose lanes on the A520 chipset has support for 26 available PCIe 3.0 lanes compared to slower PCIe 2.0 on the A320 chipset. Also CPU bundled with A520 motherboards will not support overclocking which is OK since these motherboards are low-cost option ones that come with lower power delivery subsystems and are sufficient for stock usage and are not suitable for overclocking.
The A520 chipset also favours PCIe 3.0 x 16 interface for graphics cards which is more than enough. Lack of PCIe 4.0 also means that motherboards cannot utilize speedy PCIe 4.0 SSD experience.
Overview of Technical Specifications
- 26x usable PCIe 3.0 lanes with a 3rd Gen AMD Ryzen Processor
- Up to 5 USB 3.2 Gen 2 Ports (SuperSpeed 10Gbps)
- Up to 2 native USB 3.1 Ports
- Up to 6 native USB 2.0 Ports
- Up to 4x SATA Ports
Processor Support
The A520 chipset has identical processor support to that of the mid-range B550 chipset, with official support for AMD’s current Ryzen 3000 desktop processors as well as AMD’s next-generation Ryzen 4000 processors. Like with the B550 chipset, some A520 boards come with video outputs, which all but confirms support for AMD’s Ryzen 4000 APUs – especially seeing as how A520 doesn’t officially support the earlier Ryzen 3000 or 2000 series APUs.
