AMD publishes details about the A620 chipset for the AM5 platform. Manufacturers already announced motherboards with this chipset last week. AMD didn’t release any information about the A620 at the time, so concrete specifications weren’t known yet.
AMD reports in the chipset that, among other things, the A620 chipset is connected to the CPU with four PCIe 4.0 lanes, He also writes for TechPowerUp. The chipset does not support PCIe 5.0 for video cards or SSDs, not even for the PCIe 5.0 lanes built into Ryzen 7000 CPUs. Furthermore, the chipset supports up to two USB ports with transfer rates of 10Gb/s and two USB ports with fast speeds. 5 Gb / s, six USB 2.0 ports and four SATA connectors.
It is not possible to overclock the CPU on A620 motherboards, although the DDR5 memory can be overclocked. So the chipset supports EXPO, an analogue of AMD XMP with memory overclocking profiles. Officially, the A620 chipset supports a maximum of DDR5-6000 memory.
A slide from AMD also talks about possible limited support for Ryzen 7000 CPUs with TDPs above 65W. AMD writes that it does work, but only if your motherboard has bios with a specific Agesa version. Also, multithreaded performance may be a little limited on A620 motherboards, due to the lower voltage regulation module (VRM) current limits of motherboards with these chipsets. However, the company expects these limits to have a “minor impact on game performance”.
In the past week, several manufacturers have already announced their A620 motherboards. These motherboards are relatively limited compared to the B650 or X670 models. ASUS only reported Euro prices at the time; The cheapest model from that company costs 139 euros. However, AMD states in its chipset that A620 motherboards will also be available at $85.
