AMD has quietly started releasing A620 series AM5 motherboards. Combined with the new entry-level A620 motherboards, a new AM5 system is down to around $400 to assemble. However, the new A620 series motherboards seem to have some limitations in terms of processor support.A620 motherboards have native 65W TDP support
According to press materials shared by AMD, the A620 series will basically support 65W processors and higher TDPs will not be guaranteed. As the A620 series is available immediately, the following information will be important in new system builds.
Firstly, the A620 chipset does not support PCIe Gen5 interface, which is probably the most significant difference from the B650 series. There are also fewer available PCIe lanes (36 maximum). More importantly, the chipset doesn’t support CPU overclocking, which is understandable when you consider the costs. However, the A620 series supports memory overclocking and the DDR5 standard.
AMD has confirmed that the A620 chipset may have limited support for 65W+ TDP Ryzen 7000 CPUs. This means that not all Ryzen 7000X3Ds are guaranteed to be supported by default. Interestingly, AMD uses the Ryzen 7 7800X3D (120W) processor, which will be released this week, in its A620-based system recommendations.Care should be taken when purchasing
AMD states that 65W TDP CPUs are supported by default, but there is no certainty for models with higher TDP. So this is at the discretion of the motherboard manufacturer. If they are supported, multi-core performance may be affected, but the company expects these limitations to have ‘minimal impact on gaming performance’. Ryzen 7000 CPUs with higher TDPs can be expected to perform similarly to that of a B650/X670 motherboard running in Eco Mode which limits TDP to 65W. Therefore, rather than a single core, the performance difference will indeed be experienced on the multi-core side, but it will not be a serious amount. It is also reported that the A620 chipset supports peak power up to 88 watts by default, but naturally this value will not apply to all motherboards.
Therefore, the official page of the product should be checked to make sure that the A620 motherboard supports higher TDP. Some brands provide this information on their models, but there are some that do not specify it. Currently only Biostar, Gigabyte and ASUS have a CPU support list with some A620 models supported up to Ryzen 9 7950X3D with the latest BIOS. On the MSI and ASRock side, this information has not been updated for now. As a result, it is useful to look at TDP support and processor support on the product page when buying A620 series motherboards.
