The report comes from Board Channels, which suggests that AMD is making as many as 30k of these CPUs, but the report does not clarify if these are the same SKUs that were launched in 2019, or if AMD is planning an update. In case you missed it, AMD had only two Ryzen 3000G series SKUs, the 3200G and the 3400G, both quad-core SKUs.
Back in the day, these launched at $149 and $99, but prices could be even lower now.
