The A620 chipset does not support CPU overclocking
Recently, it has been reported that AMD is about to bring a cheaper A620 chipset, and some manufacturers have submitted new motherboard models to the Eurasian Economic Commission (EEC), which means that cheaper AM5 motherboards are getting closer to players. At the same time, the A620 chipset will have two different versions. At first, it was the same Promontory 21 (PROM21) chip as the B650/X670 series, and later it will be changed to the Promontory 22 (PROM22) chip, but the functions provided by the two are likely to be the same.
Recently, Twitter user @g01d3nm4ng0 revealed that the A620 motherboard does not allow CPU overclocking, which is expected. However, it can support DDR5 memory overclocking, which means that players can manually overclock or read AMD EXPO configuration files. In the past, some A520 motherboards with AM4 platform could be overclocked by adjusting BCLK, but AMD never intended to do so on entry-level motherboards.
As has been rumored in the past, the A620 motherboard does not support PCIe 5.0. The PCIe 5.0 channel directly connected to the Ryzen 7000 series processor is downgraded to PCIe 4.0, and the number remains unchanged. At the same time, the PCIe channel provided by the PCH is also downgraded from the PCIe 4.0 of the B650/X670 series to PCIe 3.0. In addition, the A620 chipset does not support USB 3.2 Gen2x2 interfaces, only two USB 3.2 Gen2 interfaces and two USB 3.1 Gen1 interfaces.
When AMD released the Ryzen 7000 series processors and X670/B650 series chipsets, it announced that the motherboard of the AM5 platform will start at $125. However, currently, the cheapest B650 motherboard can’t meet this standard, at least it needs to be more than $160. With the introduction of the A620 chipset, the AM5 platform is expected to reduce installed costs and also boost sales of Ryzen 7000 series processors. In the financial report for the fourth quarter of 2022, the revenue of AMD’s customer business unit fell by 51% year-on-year, which was directly cut in half, largely due to the weak sales of Ryzen 7000 series processors, which ultimately dragged down the company’s performance.
