If you are interested in upgrading to the AMD Ryzen 7000 series CPUs then you will need an AM5 motherboard. The A620 chipset is for entry-level motherboards while the B650 chipset is for mid-range motherboards. In this article, we go over the differences between the AMD AM5 A620 and B650 chipsets.
AMD AM5 Platform: A620 Vs B650
Since the A620 chipset is entry-level, it does miss out on some features compared to B650. A620 is limited to CPU PCIe Gen4 and does not have Gen5 even though both chipsets have up to 28 lanes. In terms of chipset, PCIe A620 is limited to Gen3 while B650 is bumped up to Gen4 and the same is the case for PCIe uplink.
| B650 | A620 | |
| CPU PCIe | Up to 28 Gen5 | Up to 28 Gen4 |
| Chipset PCIe | 8 Gen4 | 8 Gen3 |
| PCIe Uplink | X4 Gen4 | X4 Gen3 |
| USB 32. Gen 2×2 / Gen2 | 1/4 or 0/6 | 0/2 |
| USB 3.2 Gen1 | 0 | 2 |
| USB 2.0 | 6 | 6 |
| Crossfire | Supported | Not Supported |
| CPU Overlocking | Supported | Not Supported |
| RAM Overclocking | Supported | Supported |
USB 32. Gen 2×2 is optional on the B650 motherboards while it is not available on A620. Both chipsets support RAM overclocking but CPU overclocking and Crossfire support are only available on the B650 chipset. AMD has already confirmed that there will be a B650 Extreme chipset as well which will support PCIe Gen5 for the graphics card and storage. Other features are similar as you can see in the chart below:
We do not have any news regarding when the A620 motherboards will be available but since this is an entry-level chipset, it should be available alongside the mainstream entry-level CPUs. Let us know what you think about the A620 chipset and whether or not you are interested in building an entry-level PC on the AM5 platform.
